DESCRIPTION
Palmgren Bench Grinders are equipped with a totally enclosed ballbearing motor. Armature assembly is dynamically balanced forsmooth operation. Motor housing is compact so long pieces ofwork can press against both wheels without touching the motorframe. Removable wheel guards allow for easy changing of wheels.Two-way tool rests are adjustable for wheel wear and angle grind-ing. Grinders come complete with spark guards, safety eyeshieldsand dust collection hose. (Dust Collection hose not included with82061A).
UNPACKING
Check for shipping damage. If damage has occurred, a claim mustbe filed with the carrier immediately. Check for completeness.Immediately report missing parts to dealer.
To be certain the grinding wheels have not been damaged in ship-ment, strike the edges slightly with a metal object. A ringing soundindicates a good wheel, but a dull noise may signal a fracture.
WARNING: If you suspect a wheel of being fractured, replace itimmediately. Fractured wheels may shatter, cuasing serious injury.

INSTALLATION (CONTINUED)• Grounding plug should be plugged directly into a properly
installed and grounded 3- prong grounding-type receptacle(See Figure 3).
• Do not remove or alter grounding prong in any manner. In theevent of a malfunction or breakdown, grounding provides apath of least resistance for electrical shock.
WARNING: Do not permit fingers to touch the terminals of plugwhen installing or removing from outlet.
• Plug must be plugged into matching outlet that is properlyinstalled and grounded in accordance with all local codes andordinances. Do not modify plug provided. If it will not fit in out-let, have proper outlet installed by a qualified electrician.
• Inspect tool cords periodically, and, if damaged, have repairedby an authorized service facility.
• Green (or green and yellow) conductor in cord is the groundingwire. If repair or replacement of the electric cord or plug is nec-essary, do not connect the green (or green and yellow) wire toa live terminal.
• Where a 2-prong wall receptacle is encountered, it must bereplaced with a properly grounded 3-prong receptacle installedin accordance with National Electric Code and local codes andordinances.
WARNING: This work should be performed by a qualified electrician.
• A temporary 3-prong to 2-prong grounding adapter (SeeFigure 4) is available for connecting plugs to a two pole outletif it is properly grounded.
• Do not use a 3-prong to 2-prong grounding adapter unlesspermitted by local and national codes and ordinances.
(A 3-prong to 2-prong grounding adapter is not permitted inCanada.) Where permitted, the rigid green tab or terminal onthe side of the adapter must be securely connected to a per-manent electrical ground such as a properly grounded waterpipe, a properly grounded outlet box or a properly groundedwire system.
• Many cover plate screws, water pipes and outlet boxes are notproperly grounded. To ensure proper ground, grounding meansmust be tested by a qualified electrician.
EXTENSION CORDS• The use of any extension cord will cause some drop in voltage
and loss of power.
• Wires of the extension cord must be of sufficient size to carrythe current and maintain adequate voltage.
• Running the unit on voltages which are not within ±10% of thespecified voltage may cause overheating and motor burn-out.
• Use the table to determine the minimum wire size (A.W.G.)extension cord.
• Use only 3-wire extension cords having 3-prong groundingtype plugs and 3-pole receptacles which accept the tool plug.
• If the extension cord is worn, cut or damaged in any way,replace it immediately.

ELECTRICAL CONNECTIONSWARNING: All electrical connections must be performed by aqualified electrician. Make sure tool is off and disconnected frompower source while motor is mounted, connected, reconnected oranytime wiring is inspected.
• Motor and wires are installed as shown in wiring diagram (SeeFigure 5). Motor is assembled with approved, 3-conductor cordto be used at 120/240 volts. Motor is prewired at the factory for120 volts.
• To use the grinder with a 240V power supply, have a qualifiedelectrician rewire motor and attach a 240 volt, I5A three-prongplug onto grinder line cord.
OPERATION
WARNING: Always wear safety glasses complying with UnitedStates ANSI Z87.1 (shown on package) before commencing powertool operation.
• Keep a steady, moderate pressure on the work and keep itmoving at an even pace for smooth grinding.
• Pressing too hard overheats the motor and prematurely wearsdown the grinding wheels.
• Note the original bevel angle on the item to be sharpened andtry to maintain that angle. Sharpening a cutting edge requiresremoving burrs from edge.
• Deburring edge is done best by using the grinder to pull burrfrom edge across the bevel angle.
• The grinding wheel should rotate into object being sharpened.
• Dip work into a coolant regularly to prevent overheating.Overheating can weaken metals.
