FIRE PREVENTION Hydraulic System15 Planer Operation & Maintenance Manual

Maintenance

The machine and some attachments have componentsthat are at high temperatures under normal operatingconditions. The primary source of high temperatures isthe engine and exhaust system. The electrical system, ifdamaged or incorrectly maintained, can be a source ofarcs or sparks.

Flammable debris (leaves, straw, etc.) must be removedregularly. If flammable debris is allowed to accumulate, itcan cause a fire hazard. Clean often to avoid thisaccumulation. Flammable debris in the enginecompartment is a potential fire hazard.

The operators area, engine compartment and enginecooling system must be inspected every day and cleanedif necessary to prevent fire hazards and overheating.

All fuels, most lubricants and some coolant mixtures areflammable. Flammable fluids that are leaking or spilledonto hot surfaces or onto electrical components cancause a fire.

Operation

Do not use the machine where exhaust, arcs, sparks orhot components can contact flammable material,explosive dust or gases.

Electrical

Check all electrical wiring and connections for damage.Keep the battery terminals clean and tight. Repair orreplace any damaged part or wires that are loose orfrayed.

Battery gas can explode and cause serious injury. Usethe procedure in the Operation & Maintenance Manualfor connecting the battery and for jump starting. Do notjump start or charge a frozen or damaged battery. Keepany open flames or sparks away from batteries. Do notsmoke in battery charging area.

Check hydraulic tubes, hoses and fittings for damageand leakage. Never use open flame or bare skin to checkfor leaks. Hydraulic tubes and hoses must be properlyrouted and have adequate support and secure clamps.Tighten or replace any parts that show leakage.

Always clean fluid spills. Do not use gasoline or dieselfuel for cleaning parts. Use commercial nonflammablesolvents.

Fueling

Stop the engine and let it cool before adding fuel. Nosmoking! Do not refuel a machine near open flames orsparks. Fill the fuel tank outdoors.

Ultra Low Sulfur Diesel (ULSD) poses a greater staticignition hazard than earlier diesel formulations withhigher Sulfur content. Avoid death or serious injury fromfire or explosion. Consult with your fuel or fuel systemsupplier to ensure the delivery system is in compliancewith fueling standards for proper grounding and bondingpractices.

Starting

Do not use ether or starting fluids on any engine that hasglow plugs. These starting aids can cause explosion andinjure you or bystanders.

Use the procedure in the Operation & MaintenanceManual for connecting the battery and for jump starting.

Spark Arrester Exhaust System

The spark arrester exhaust system is designed to controlthe emission of hot particles from the engine and exhaustsystem, but the muffler and the exhaust gases are stillhot.

Check the spark arrester exhaust system regularly tomake sure it is maintained and working properly. Use theprocedure in the Operation & Maintenance Manual forcleaning the spark arrester muffler (if equipped).

Cutting Procedure (Contd)

Figure 56

Press the trigger (Item 1) [Figure 56] on the rightsteering lever once. The drum will rotate.

With the loader in motion, adjust the skis to the desiredcutting depth. (See Hydraulic Ski Adjustment on Page42.)

Keep both hands on the steering levers. When therotating drum contacts the work surface, it will suddenlyshift the loader position. Be prepared to make a loaderposition correction to keep the planer cutting on thecorrect course.

Slowly tilt the planer forward into the work surface untilboth skis are flat on the work surface [Figure 57].

For optimum planer performance the skis should beadjusted while the loader is in motion, so the planer drumbits are making as shallow a cut as necessary to removeany surface imperfections, stripes or markings on thework surface.

The planer skis (Item 1) must both be on the worksurface and the stabilizer wheels (Item 2) [Figure 57]must be off the work surface at all times while the planeris cutting.

Excessive vibration usually indicates the planer skis arenot properly contacting the work surface. Lower the liftarms and tilt the planer forward as needed to maintainconstant contact with the work surface.

Cutting Procedure (Contd)

Figure 58

The planer drum rotates in the direction of the arrow[Figure 58].

NOTE: Right ski and right side plate removed forpicture clarity.

Drive forward into the material that is to be planed. Theplaner undercuts the material, breaking it out in anupward direction.

Faster loader travel speeds will create a rougher surface.Adjust travel speed and cutting depth until the desiredcutting results are obtained.

Cutting Concrete: The recommended cutting depth perpass should be 12,7 mm (0.5 in) or less to achievedesired cutting depth make multiple passes.

Cutting Asphalt: The recommended cutting depth perpass should be 76,2 mm (3 in) or less. The performanceof the planer cutting asphalt will best determine thecutting depth. The age of the asphalt, the size of theaggregate and the temperature of the asphalt will allaffect how deep of a cut that can be made, and at whattravel speed.

Figure 59

Mill your first pass at the desired depth. Now return to theoriginal starting point, align the ski so it just overlaps theedge of the previous cut, do not adjust the ski (Item 1)[Figure 59]. This will keep the cutting depth the same asthe first pass.

Adjust the ski on the milled surface (Item 2) [Figure 59]so the planer housing remains level providing a level cut.
