WARNING

Mar ‘95

ELECTRIC AND MAGNETIC FIELDSmay be dangerous

2.a. Electric current flowing through any conductor causes localized Electric and Magnetic Fields (EMF). Welding current creates EMF fields around welding cables and welding machines

2.b. EMF fields may interfere with some pacemakers, andwelders having a pacemaker should consult their physicianbefore welding.

2.c. Exposure to EMF fields in welding may have other healtheffects which are now not known.

2.d. All welders should use the following procedures in order tominimize exposure to EMF fields from the welding circuit:

2.d.1. Route the electrode and work cables together - Securethem with tape when possible.

2.d.2. Never coil the electrode lead around your body.

2.d.3. Do not place your body between the electrode andwork cables. If the electrode cable is on your right side, the work cable should also be on your right side.

2.d.4. Connect the work cable to the workpiece as close aspossible to the area being welded.

2.d.5. Do not work next to welding power source.

1.h. To avoid scalding, do not remove theradiator pressure cap when the engine ishot.

ARC RAYS can burn.4.a. Use a shield with the proper filter and cover

plates to protect your eyes from sparks andthe rays of the arc when welding or observingopen arc welding. Headshield and filter lensshould conform to ANSI Z87. I standards.

4.b. Use suitable clothing made from durable flame-resistantmaterial to protect your skin and that of your helpers fromthe arc rays.

4.c. Protect other nearby personnel with suitable, non-flammablescreening and/or warn them not to watch the arc nor exposethemselves to the arc rays or to hot spatter or metal.

ELECTRIC SHOCK cankill.3.a. The electrode and work (or ground) circuits

are electrically “hot” when the welder is on.Do not touch these “hot” parts with your bareskin or wet clothing. Wear dry, hole-free

gloves to insulate hands.

3.b. Insulate yourself from work and ground using dry insulation.Make certain the insulation is large enough to cover your fullarea of physical contact with work and ground.

In addition to the normal safety precautions, if weldingmust be performed under electrically hazardousconditions (in damp locations or while wearing wetclothing; on metal structures such as floors, gratings orscaffolds; when in cramped positions such as sitting,kneeling or lying, if there is a high risk of unavoidable oraccidental contact with the workpiece or ground) usethe following equipment:

• Semiautomatic DC Constant Voltage (Wire) Welder.• DC Manual (Stick) Welder.• AC Welder with Reduced Voltage Control.

3.c. In semiautomatic or automatic wire welding, the electrode,electrode reel, welding head, nozzle or semiautomaticwelding gun are also electrically “hot”.

3.d. Always be sure the work cable makes a good electricalconnection with the metal being welded. The connectionshould be as close as possible to the area being welded.

3.e. Ground the work or metal to be welded to a good electrical(earth) ground.

3.f. Maintain the electrode holder, work clamp, welding cable andwelding machine in good, safe operating condition. Replacedamaged insulation.

3.g. Never dip the electrode in water for cooling.

3.h. Never simultaneously touch electrically “hot” parts ofelectrode holders connected to two welders because voltagebetween the two can be the total of the open circuit voltageof both welders.

3.i. When working above floor level, use a safety belt to protectyourself from a fall should you get a shock.

3.j. Also see Items 6.c. and 8.

Mar ‘95

FUMES AND GASEScan be dangerous.5.a. Welding may produce fumes and gases

hazardous to health. Avoid breathing thesefumes and gases.When welding, keepyour head out of the fume. Use enoughventilation and/or exhaust at the arc to keep

fumes and gases away from the breathing zone. Whenwelding with electrodes which require specialventilation such as stainless or hard facing (seeinstructions on container or MSDS) or on lead orcadmium plated steel and other metals or coatingswhich produce highly toxic fumes, keep exposure aslow as possible and below Threshold Limit Values (TLV)using local exhaust or mechanical ventilation. Inconfined spaces or in some circumstances, outdoors, arespirator may be required. Additional precautions arealso required when welding on galvanized steel.

5.b. Do not weld in locations near chlorinated hydrocarbon vaporscoming from degreasing, cleaning or spraying operations.The heat and rays of the arc can react with solvent vapors toform phosgene, a highly toxic gas, and other irritating prod-ucts.

5.c. Shielding gases used for arc welding can displace air andcause injury or death. Always use enough ventilation,especially in confined areas, to insure breathing air is safe.

5.d. Read and understand the manufacturer’s instructions for thisequipment and the consumables to be used, including thematerial safety data sheet (MSDS) and follow youremployer’s safety practices. MSDS forms are available fromyour welding distributor or from the manufacturer.

5.e. Also see item 1.b.

FOR ELECTRICALLYpowered equipment.

8.a. Turn off input power using the disconnectswitch at the fuse box before working onthe equipment.

8.b. Install equipment in accordance with the U.S. NationalElectrical Code, all local codes and the manufacturer’srecommendations.

8.c. Ground the equipment in accordance with the U.S. NationalElectrical Code and the manufacturer’s recommendations.

CYLINDER may explodeif damaged.7.a. Use only compressed gas cylinders

containing the correct shielding gas for theprocess used and properly operatingregulators designed for the gas and

pressure used. All hoses, fittings, etc. should be suitable forthe application and maintained in good condition.

7.b. Always keep cylinders in an upright position securelychained to an undercarriage or fixed support.

7.c. Cylinders should be located:• Away from areas where they may be struck or subjected tophysical damage.

• A safe distance from arc welding or cutting operations andany other source of heat, sparks, or flame.

7.d. Never allow the electrode, electrode holder or any otherelectrically “hot” parts to touch a cylinder.

7.e. Keep your head and face away from the cylinder valve outletwhen opening the cylinder valve.

7.f. Valve protection caps should always be in place and handtight except when the cylinder is in use or connected foruse.

7.g. Read and follow the instructions on compressed gascylinders, associated equipment, and CGA publication P-l,“Precautions for Safe Handling of Compressed Gases inCylinders,” available from the Compressed Gas Association1235 Jefferson Davis Highway, Arlington, VA 22202.

Mar ‘95

WELDING SPARKS cancause fire or explosion.6.a. Remove fire hazards from the welding area.

If this is not possible, cover them to preventthe welding sparks from starting a fire.Remember that welding sparks and hot

materials from welding can easily go through small cracksand openings to adjacent areas. Avoid welding nearhydraulic lines. Have a fire extinguisher readily available.

6.b. Where compressed gases are to be used at the job site,special precautions should be used to prevent hazardoussituations. Refer to “Safety in Welding and Cutting” (ANSIStandard Z49.1) and the operating information for theequipment being used.

6.c. When not welding, make certain no part of the electrodecircuit is touching the work or ground. Accidental contactcan cause overheating and create a fire hazard.

6.d. Do not heat, cut or weld tanks, drums or containers until theproper steps have been taken to insure that such procedureswill not cause flammable or toxic vapors from substancesinside. They can cause an explosion even though they havebeen “cleaned”. For information, purchase “RecommendedSafe Practices for the Preparation for Welding and Cutting ofContainers and Piping That Have Held HazardousSubstances”, AWS F4.1 from the American Welding Society(see address above).

6.e. Vent hollow castings or containers before heating, cutting orwelding. They may explode.

6.f. Sparks and spatter are thrown from the welding arc. Wear oilfree protective garments such as leather gloves, heavy shirt,cuffless trousers, high shoes and a cap over your hair. Wearear plugs when welding out of position or in confined places.Always wear safety glasses with side shields when in awelding area.

6.g. Connect the work cable to the work as close to the weldingarea as practical. Work cables connected to the buildingframework or other locations away from the welding areaincrease the possibility of the welding current passingthrough lifting chains, crane cables or other alternate cir-cuits. This can create fire hazards or overheat lifting chainsor cables until they fail.

PRÉCAUTIONS DE SÛRETÉPour votre propre protection lire et observer toutes les instructionset les précautions de sûreté specifiques qui parraissent dans cemanuel aussi bien que les précautions de sûreté générales suiv-antes:

Sûreté Pour Soudage A L’Arc1. Protegez-vous contre la secousse électrique:

a. Les circuits à l’électrode et à la piéce sont sous tensionquand la machine à souder est en marche. Eviter toujourstout contact entre les parties sous tension et la peau nueou les vétements mouillés. Porter des gants secs et sanstrous pour isoler les mains.

b. Faire trés attention de bien s’isoler de la masse quand onsoude dans des endroits humides, ou sur un planchermetallique ou des grilles metalliques, principalement dans les positions assis ou couché pour lesquelles une grandepartie du corps peut être en contact avec la masse.

c. Maintenir le porte-électrode, la pince de masse, le câblede soudage et la machine à souder en bon et sûr étatdefonctionnement.

d.Ne jamais plonger le porte-électrode dans l’eau pour lerefroidir.

e. Ne jamais toucher simultanément les parties sous tensiondes porte-électrodes connectés à deux machines à souderparce que la tension entre les deux pinces peut être letotal de la tension à vide des deux machines.

f. Si on utilise la machine à souder comme une source decourant pour soudage semi-automatique, ces precautionspour le porte-électrode s’applicuent aussi au pistolet desoudage.

2. Dans le cas de travail au dessus du niveau du sol, se protégercontre les chutes dans le cas ou on recoit un choc. Ne jamaisenrouler le câble-électrode autour de n’importe quelle partiedu corps.

3. Un coup d’arc peut être plus sévère qu’un coup de soliel,donc:

a. Utiliser un bon masque avec un verre filtrant appropriéainsi qu’un verre blanc afin de se protéger les yeux du ray-onnement de l’arc et des projections quand on soude ouquand on regarde l’arc.

b. Porter des vêtements convenables afin de protéger lapeau de soudeur et des aides contre le rayonnement del‘arc.

c. Protéger l’autre personnel travaillant à proximité ausoudage à l’aide d’écrans appropriés et non-inflammables.

4. Des gouttes de laitier en fusion sont émises de l’arc desoudage. Se protéger avec des vêtements de protection libresde l’huile, tels que les gants en cuir, chemise épaisse, pan-talons sans revers, et chaussures montantes.

5. Toujours porter des lunettes de sécurité dans la zone desoudage. Utiliser des lunettes avec écrans lateraux dans les

zones où l’on pique le laitier.

6. Eloigner les matériaux inflammables ou les recouvrir afin deprévenir tout risque d’incendie dû aux étincelles.

7. Quand on ne soude pas, poser la pince à une endroit isolé dela masse. Un court-circuit accidental peut provoquer unéchauffement et un risque d’incendie.

8. S’assurer que la masse est connectée le plus prés possiblede la zone de travail qu’il est pratique de le faire. Si on placela masse sur la charpente de la construction ou d’autresendroits éloignés de la zone de travail, on augmente le risquede voir passer le courant de soudage par les chaines de lev-age, câbles de grue, ou autres circuits. Cela peut provoquerdes risques d’incendie ou d’echauffement des chaines et descâbles jusqu’à ce qu’ils se rompent.

9. Assurer une ventilation suffisante dans la zone de soudage.Ceci est particuliérement important pour le soudage de tôlesgalvanisées plombées, ou cadmiées ou tout autre métal quiproduit des fumeés toxiques.

10. Ne pas souder en présence de vapeurs de chlore provenantd’opérations de dégraissage, nettoyage ou pistolage. Lachaleur ou les rayons de l’arc peuvent réagir avec les vapeursdu solvant pour produire du phosgéne (gas fortement toxique)ou autres produits irritants.

11. Pour obtenir de plus amples renseignements sur la sûreté,voir le code “Code for safety in welding and cutting” CSAStandard W 117.2-1974.

PRÉCAUTIONS DE SÛRETÉ POURLES MACHINES À SOUDER ÀTRANSFORMATEUR ET ÀREDRESSEUR

1. Relier à la terre le chassis du poste conformement au code del’électricité et aux recommendations du fabricant. Le dispositifde montage ou la piece à souder doit être branché à unebonne mise à la terre.

2. Autant que possible, I’installation et l’entretien du poste seronteffectués par un électricien qualifié.

3. Avant de faires des travaux à l’interieur de poste, la debranch-er à l’interrupteur à la boite de fusibles.

4. Garder tous les couvercles et dispositifs de sûreté à leurplace.

SAFETY PRECAUTIONS

ADDITIONAL SAFETY PRECAUTIONSAlways operate the welder with the roof and casesides in place as this provides maximum protec-tion from moving parts and assures proper cool-ing air flow.

Read and understand all Safety Precautionsbefore operating this machine. Always followthese and any other safety procedures included inthis manual and in the Engine Owner’s Manual.

MACHINEGROUNDING

Because this portable engine driven welder or genera-tor creates it’s own power, it is not necessary to con-nect it’s frame to an earth ground, unless the machineis connected to premises wiring (your home, shop,etc.).

To prevent dangerous electric shock, other equipmentto which this engine driven welder supplies powermust:• be grounded to the frame of the welder using a

grounded type plug, or• be double insulated.

When this welder is mounted on a truck or trailer, it’sframe must be securely connected to the metal frameof the vehicle.

Where this engine driven welder is connected topremises wiring such as that in your home or shop, it’sframe must be connected to the system earth ground.See further connection instructions in the section enti-tled “Standby Power Connections”, as well as the arti-cle on grounding in the latest U.S. National ElectricalCode and the local code.

In general, if the machine is to be grounded, it shouldbe connected with a #8 or larger copper wire to a solidearth ground such as a metal water pipe going into theground for at least ten feet and having no insulatedjoints, or to the metal framework of a building whichhas been effectively grounded. The U.S. NationalElectrical Code lists a number of alternate means ofgrounding electrical equipment. A machine groundingstud marked with the symbol is provided on thefront of the welder.

SPARK ARRESTERSome federal, state, or local laws may require thatgasoline engines be equipped with exhaust sparkarresters when they are operated in certain locationswhere unarrested sparks may present a fire hazard.The standard muffler included with this welder doesnot qualify as a spark arrester. When required by localregulations, the K894-1 spark arrester must beinstalled and properly maintained.

An incorrect arrester may lead to damage to theengine or adversely affect performance.

TRAILERSThe recommended trailer for use with this equipmentfor road, in plant and yard towing by a vehicle(1) isLincoln’s K957-1. If the user adapts a non-Lincoln trail-er, they must assume responsibility that the method ofattachment and usage does not result in a safety haz-ard nor damage the welding equipment. Some of thefactors to be concidered are as follows:

• Design capacity of trailer vs. weight of Lincolnequipment and likely additional attachments.

• Proper support of, and attachment to, the base ofthe welding equipment so there will be no unduestress to the framework.

• Proper placement of the equipment on the trailer toinsure stability side to side and front to back whenbeing moved and when standing by itself whilebeing operated or serviced.

CAUTION

Do not attempt to use this equipment until youhave thoroughly read the engine manufacturer’smanual supplied with your welder. It includesimportant safety precautions, detailed enginestarting, operating and maintenance instructions,and parts lists.------------------------------------------------------------------------

ELECTRIC SHOCK can kill.• Do not touch electrically live parts or

electrode with skin or wet clothing.• Insulate yourself from work and

ground• Always wear dry insulating gloves.

------------------------------------------------------------------------ENGINE EXHAUST can kill.• Use in open, well ventilated areas or

vent exhaust outside.

------------------------------------------------------------------------MOVING PARTS can injure.• Do not operate with doors open or

guards off.• Stop engine before servicing.• Keep away from moving parts.

------------------------------------------------------------------------

•See additional warning information atfront of this operator’s manual.

-----------------------------------------------------------

WARNING

• Typical conditions of use, i.e., travel speed; rough-ness of surface on which the trailer will be operat-ed; environmental conditions; like maintenance.

• Conformance with federal, state and local laws.(1)

(1) Consult applicable federal, stste and lpcal lawsregarding specific requirements for use on publichighways.

PRE-OPERATION SERVICE

READ the engine operating and maintenanceinstructions supplied with this machine.

OIL

The ZR-10 is shipped with the engine crankcase filledwith SAE 10W-30 oil. Check the oil level before start-ing the engine. If it is not up to the full mark on the dipstick, add oil as required. Make certain that the oil fillercap is tightened securely. Refer to the engine Owner’sManual for specific oil recommendations.

FUEL

Fill the fuel tank with clean, fresh, lead-free gasoline.Observe fuel gauge while filling to prevent overfilling.

BATTERY CONNECTIONS

This welder is shipped with the negative battery cabledisconnected. Make sure that the Engine Switch is inthe “STOP” position and attach the disconnectedcable securely to the negative battery terminal beforeattempting to operate the machine. If the battery isdischarged and does not have enough power to startthe engine, see the battery charging instructions in theBattery section.

WELDING OUTPUT CABLES

With the engine off, connect the electrode and workcables to the studs provided.These connectionsshould be checked periodically and tightened if neces-sary. Loose connections will result in overheating ofthe output studs.

When welding at a considerable distance from thewelder, be sure you use ample size welding cables.Listed below are copper cable sizes recommended forthe rated current and duty cycle. Lengths stipulatedare the distance from the welder to work and back tothe welder again. Cable sizes are increased forgreater lengths primarily for the purpose of minimizingcable voltage drop.

Connect the work cable directly to the work piece.Do not allow welding current to return throughelectrical conduit, pipes or building structuresthat are not suitable to carry welding current. Donot connect the work cable to the welding frame.Stray welding currents may also damage auxiliarypower cords or equipment.

ANGLE OF OPERATION

Internal combustion engines are designed to run in alevel condition which is where the optimum perfor-mance is achieved. The maximum angle of operationfor the engine is 15 degrees from horizontal in anydirection. If the engine is to be operated at an angle,provisions must be made for checking and maintain-ing the oil at the normal (FULL) oil capacity in thecrankcase in a level condition.

When operating at an angle, the effective fuel capaci-ty will be slightly less than the specified 10 gallons.

HIGH ALTITUDE OPERATION

If the ZR-10 will be consistently operated at altitudesabove 5000 ft, a carburetor jet designed for high alti-tudes should be installed. This will result in betterfuel economy, cleaner exhaust, and longer spark pluglife. It wil l not give increased power which isdecreased at higher altitudes. Engine horsepower isreduced by 3.5% per 1000 feet for altitudes above377 feet.

Do not operate a ZR-10 with a high altitude jetinstalled at altitudes below 5000 ft. This willresult in the engine running too lean and result inhigher engine operating temperatures which canshorten engine life.

High altitude jet kits are available from the enginemanufacturer.

MUFFLER RELOCATION

Shut off welder and allow muffler to cool beforetouching muffler.

The ZR-10 is shipped with the exhaust coming out onthe left side. The exhaust can be changed to theopposite side by removing the two screws that holdthe exhaust port cover in place and installing thecover on the opposite side. (Operating the ZR-10without the cover in place will result in a higher noiselevel and no increase in machine output.)

LOCATION / VENTILATIONThe welder should be located to provide an unrestrict-ed flow of clean, cool air to the cooling air inlets and toavoid heated air coming out of the welder recirculating back to the cooling air inlet. Also, locate the welderso that engine exhaust fumes are properly vented toan outside area.

“ CONTROL” SWITCH

Provides a fine welding current adjustment within theRange Switch settings in the STICK/TIG mode andwelding voltage control with the Range switch set inthe wire feed mode.

“IDLER” SWITCH

The idler switch has two positions, “HIGH” and“AUTO”.

When in “HIGH” ( ) position, the engine will runcontinuously at high idle.When in “AUTO” ( / ) idle position, the idleroperates as follows:

• WELDING

When the electrode touches the work, the welding arc is initiated and the engine accelerates to fullspeed.

After welding ceases (and no auxiliary power isbeing drawn), the engine will return to low idleafter approximately 10 to 16 seconds.

• AUXILIARY POWER

With the engine running at low idle and auxiliarypower for lights or tools is drawn (approximately100-150 watts or greater or 1500W on 460v 3ø) from the receptacles, the engine will accelerate tohigh speed. If no power is being drawn from the receptacles (and not welding) for 10-16 seconds, the idler reduces the engine speed to low idle.

460 Volt 3 Phase Receptacle with GroundThe 460 volt receptacle can supply 12.5 amps of 3phase power, or up to 15 amps of single phase power.A NEMA plug L16-20P is required to use this recepta-cle. The ground (GND) connection is connected to themachine frame, it is NOT the neutral of the threephase connection, and should under no circum-stances be connected to the neutral of any 3 phaseload. Do not connect 460V 3 phase to premiseswiring.

If 460 volt single phase load is to be run, the X leadmust be one of the leads in the circuit in order for theautomatic idle to function. Using a NEMA plug L16-20P, connect either X and Y or X and Z to the recep-tacle, as well as the machine ground.

All auxiliary power is protected by circuit breakers withthe following values:The 115V has 15 amp circuit breakers for each plug ofthe duplex receptacle. The 230V has 50 amp circuitbreakers for each hot lead going the 230V receptacle.The 460V 3 phase circuit breakers / switch has a 3phase, 15 amp circuit breaker.

Ground WirePeriodically check the ground wire at plugs, powercords and auxiliary loads to ensure that the groundingcircuit is intact and connected.

MOTOR STARTINGMost 1.5 hp AC single phase motors can be started ifthere is no load on the motor or other load connectedto the machine, since the full load current rating of a1.5 hp motor is approximately 20 amperes (10amperes for 230 volt motors). The motor may be runat full load when plugged into only one side of theduplex receptacle. Larger motors through 2 hp can berun provided the receptacle rating as previously statedis not exceeded. This may necessitate 230V operationonly.

The 460 volt 3 phase output of the ZR-10 is capableof running most 460VAC 3 phase motors up to 10HP.A 10HP motor must be started with no load on themotor and no other load connected to the machine,since the full load current of a 10HP 460VAC 3 phasemotor is approximately 12.5 amps. Refer to the recon-nect phase output to any load, the ground at the 3phase receptacle is NOT the neutral of 3 phase con-nection, and should under no circumstance be con-nected to the neutral of any 3 phase load.

ZR-10

AUXILIARY POWERThe ZR-10 can provide up to 9,000 watts of 115/230volts AC, single phase 60Hz power, or 460 Volts,3phase, 60 Hz for continuous use. The front of themachine includes four receptacles for connecting theAC power plugs; one 20 amp 460 volt 3 phase NEMA,one 50 amp 115/230 volt NEMA 14-50R receptacleand two 20 amp 115 volt NEMA 5-20R receptacles.Do not use 3 phase power and single phase powersimultaneously.

Do not connect any plugs that connect to the powerreceptacles in parallel.------------------------------------------------------------------------Start the engine and set the “IDLER” control switch tothe desired operating mode. Set the “CONTROL” to10. Voltage is now correct at the receptacles for auxil-iary power.

A qualified person must make connections to plugs.Connect each wire of the cord to the proper plug ter-minal, especially ground.

115/230 Volt Dual Voltage Receptacle

The 115/230 volt receptacle can supply up to 39amps of 230 volt power to a two wire circuit, up to 39amps of 115 volts power from each side of a threewire circuit (up to 78 amps total). Do not connect the115 volt circuits in parallel.

115 V Duplex ReceptaclesThe 115V auxiliary power receptacles should only beused with three wire grounded type plugs or approveddouble insulated tools with two wire plugs.

The current rating of any plug used with the systemmust be at least equal to the current load through theassociated receptacle (Refer to Tables I and II). Donot attempt to connect power receptacles in parallel.

STANDBY POWER CONNECTIONS

The ZR-10 is suitable for temporary, standby, or emer-gency power using the engine manufacturer’s recom-mended maintenance schedule.

The ZR-10 can be permanently installed as a standbypower unit for 230V-3 wire, single phase 35 ampereservice.

(Connections must be made by a licensed electri-cian who can determine how the 115/230V powercan be adapted to the particular installation andcomply with all applicable electrical codes.)The following information can be used as a guideby the electrician for most applications (refer alsoto the connection diagram shown in Figure 1.)

• Install a double pole, double throw switch betweenthe power company meter and the premises discon-nect.

• Switch rating must be the same or greater than thecustomer’s premises disconnect and service over-current protection.

• Take necessary steps to assure load is limited tothe capacity of the ZR-10 by installing a 35 amp230V double pole circuit breaker. Maximum ratedload for the 230V auxiliary is 35 amperes. Loadingabove 35 amperes will reduce output voltage belowthe allowable-10% of rated voltage which may dam-age appliances or other motor-driven equipment.

• Install a 50 amp 115/230V plug (NEMA type 14-50)to the Double Pole Circuit Breaker using No. 8, 4conductor cable of the desired length. (The50 amp115/230V plug is available in the optional plug kit.)

• Plug this cable into the 50 amp 115/230V receptacleon the ZR-10 case front.

WARNING

AUXILLIARY POWER WHILE WELDING

It must be noted that the above auxiliary power ratingsare with no welding load. Simultaneous welding andpower loads are permitted by following Table III. Thepermissible currents shown assume that current isbeing drawn from either the 115V or 230V supply (notboth at the same time). Also, the “Output Control” isset at “10” for maximum auxiliary power.

WARNING

ROUTINE MAINTENANCE• At the end of each day’s use, refill the fuel tank to

minimize moisture condensation in the tank.Running out of fuel tends to draw dirt into the fuelsystem. Also, check the crankcase oil level and addoil if indicated.

Make certain that the oil filler cap is securely tight-ened after checking or adding oil. If the cap is nottight, oil consumption can increase significantlywhich may be evidenced by white smoke comingfrom the exhaust.

• OIL - Maintenance schedule for changing the oil andoil filter after break-in:

The above schedule is for normal operating condi-tions. More frequent oil changes are required withdusty, high temperature and other severe operatingconditions. Refer to the maintenance section of theEngine Owner's Manual for more information.

NOTE: Engine life will be reduced if the oil and oil fil-ter are not changed according to the manufacturer’srecommendation.

• Air Cleaner - With normal operating conditions, themaintenance schedule for cleaning and re-oilingthe foam pre-filter is every 25 hours and replace-ment of the air cleaner filter every 100 hours.More frequent servicing is required with dustyoperating conditions. Refer to the maintenancesection of the Engine Owner’s Manual for moreinformation.

• Refer to the maintenance section of the EngineOwner’s Manual for the maintenance schedule,spark plug servicing, cooling system servicing, andfuel filter replacement.

• Blow out the machine with low pressure air period-ically. In particularly dirty locations, this may berequired once a week.

• Output Range Selector and Polarity Switches:Switch contacts should not be greased. To keepcontacts clean, rotate the switch through its entirerange frequently. Good practice is to turn the han-dle from maximum to minimum setting twice eachmorning before starting to weld.
