Palmgren Operating Manual & Parts List 9682072A, 9682073A and 9682075A
DESCRIPTION
Palmgren Bench Grinders are equipped with a totally enclosed ball
bearing motor. Armature assembly is dynamically balanced for
smooth operation. Motor housing is compact so long pieces of
work can press against both wheels without touching the motor
frame. 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 eyeshields
and dust collection hose. .
UNPACKING
Check for shipping damage. If damage has occurred, a claim must
be filed with the carrier immediately. Check for completeness. Im-
mediately 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 sound
indicates a good wheel, but a dull noise may signal a fracture.
WARNING: If you suspect a wheel of being fractured, replace it
immediately. Fractured wheels may shatter, causing serious injury.

SAFETY RULES
WARNING: For your own safety, read operating instructions
manual before operating tool.
PROPOSITION 65 WARNING: Some dust created by using
power tools contain chemicals known to the state of California to
cause cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:
• Lead from lead-based paints
• Crystalline silica from bricks and cement and other masonry
products.
• Arsenic and chromium from chemically treated lumber.
Your risk from these exposures varies, depending on how often you
do this type of work. To reduce your exposure to these chemicals;
work in a well ventilated area and work with approved safety
equipment. Always wear OSHA/NIOSH approved, properly fitting
face mask or respirator when using such tools.
BE PREPARED FOR JOB
• Wear proper apparel. Do not wear loose clothing, gloves, neck-
ties, rings, bracelets or other jewelry which may get caught in
moving parts of machine.
• Wear protective hair covering to contain long hair.
• Wear safety shoes with non-slip soles.
• Wear safety glasses complying with United States ANSI Z87.1.
Everyday glasses have only impact resistant lenses. They are
NOT safety glasses.
• Wear face mask or dust mask if operation is dusty.
• Be alert and think clearly. Never operate power tools when tired,
intoxicated or when taking medications that cause drowsiness.
PREPARE WORK AREA FOR JOB
• Keep work area clean. Cluttered work areas and work benches
invite accidents.
• Do not use power tools in dangerous environments. Do not use
power tools in damp or wet locations. Do not expose power
tools to rain.
• Work area should be properly lighted.
• Use proper extension cord. Make sure your extension cord is in
good condition. When using an extension cord, be sure to use
one heavy enough to carry the current your product will draw.
An undersized cord will cause a drop in line voltage resulting in
loss of power and overheating. Extension Cord Table on page 4
shows the correct size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next heavier gage.
The smaller the gage number, the heavier the cord.
• Keep visitors at a safe distance from work area.
• Keep children out of the workplace. Make workshop childproof.
Use padlocks, master switches or remove switch keys to prevent
any unintentional use of power tools.
TOOL SHOULD BE MAINTAINED
• Always unplug tool prior to inspection.
• Consult manual for specific maintaining and adjusting
procedures.
• Keep tool clean for safest operation.
• Remove adjusting tools. Form habit of checking to see that
adjusting tools are removed before turning machine on.
• Keep all parts in working order. Check to determine that the
guard or other parts will operate properly and perform their
intended function.
• Check for damaged parts. Check for alignment of moving parts,
binding of moving parts, breakage of parts, mounting and any
other condition that may affect a tool’s operation.
• A guard or other part that is damaged should be properly re-
paired or replaced. Do not perform makeshift repairs. (Use the
parts list to order replacement parts.)
• Maintain tools with care. Keep tools sharp and clean for best
and safest performance. Follow instructions for lubricating and
changing accessories.
