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
grinding. Grinders come complete with spark guards and safety
eyeshields.
UNPACKING
Check for shipping damage. If damage has occurred, a claim must
be 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 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.

INSTALLATION (CONTINUED)
• Do not remove or alter grounding prong in any manner. In the
event of a malfunction or breakdown, grounding provides a
path of least resistance for electrical shock.
WARNING: Do not permit fingers to touch the terminals of plug
when installing or removing from outlet.
• Plug must be plugged into matching outlet that is properly in-
stalled and grounded in accordance with all local codes and or-
dinances. Do not modify plug provided. If it will not fit in outlet,
have proper outlet installed by a qualified electrician.
• Inspect tool cords periodically, and, if damaged, have repaired
by an authorized service facility.
• Green (or green and yellow) conductor in cord is the grounding
wire. If repair or replacement of the electric cord or plug is nec-
essary, do not connect the green (or green and yellow) wire to a
live terminal.
• Where a 2-prong wall receptacle is encountered, it must be re-
placed with a properly grounded 3-prong receptacle installed
in accordance with National Electric Code and local codes and
ordinances.
WARNING: This work should be performed by a qualified
electrician.
• A temporary 3-prong to 2-prong grounding adapter (See Figure
3) is available for connecting plugs to a two pole outlet if it is
properly grounded.
• Do not use a 3-prong to 2-prong grounding adapter unless per-
mitted by local and national codes and ordinances.
(A 3-prong to 2-prong grounding adapter is not permitted in
Canada.) Where permitted, the rigid green tab or terminal on the
side of the adapter must be securely connected to a permanent
electrical ground such as a properly grounded water pipe, a prop-
erly grounded outlet box or a properly grounded wire system.
• Many cover plate screws, water pipes and outlet boxes are not
properly grounded. To ensure proper ground, grounding means
must 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 carry
the current and maintain adequate voltage.
• Running the unit on voltages which are not within ±10% of the
specified voltage may cause overheating and motor burn-out.
• Use the table to determine the minimum wire size (A.W.G.) ex-
tension cord.
• Use only 3-wire extension cords having 3-prong grounding
type plugs and 3-pole receptacles which accept the tool plug.
• If the extension cord is worn, cut or damaged in any way, re-
place it immediately.
ELECTRICAL CONNECTIONS
WARNING: All electrical connections must be performed by a
qualified electrician. Make sure tool is off and disconnected from
power source while motor is mounted, connected, reconnected or
anytime wiring is inspected.
• Motor and wires are installed as shown in wiring diagram (See
Figure 4). Motor is assembled with approved, 3-conductor cord to
be used at 120 volts. Motor is prewired at the factory for 120 volts.
OPERATION
CAUTION: Always follow proper operating procedures as defined
in this manual even if you are familiar with use of this or similar
tools. Remember that being careless for even a fraction of a second
can result in severe personal injury.
WARNING: Always wear safety glasses complying with United
States ANSI Z87.1 (shown on package) before commencing power
tool operation.
• Keep a steady, moderate pressure on the work and keep it mov-
ing at an even pace for smooth grinding.
• Pressing too hard overheats the motor and prematurely wears
down the grinding wheels.
• Note the original bevel angle on the item to be sharpened and
try to maintain that angle. Sharpening a cutting edge requires
removing burrs from edge.
• Deburring edge is done best by using the grinder to pull burr
from edge across the bevel angle.
• The grinding wheel should rotate into object being sharpened.
• Dip work into a coolant regularly to prevent overheating. Over-
heating can weaken metals.
MAINTENANCE
• As wheels wear, tool rests should be positioned closer to the
face of the wheels.
• The gap between the wheel and the tool rest should not be
greater than 1/16”. When the wheels are worn to the extent that
the 1/16” maximum gap cannot be maintained, the wheels
should be replaced.
• Replacement wheels for model 9682090 must have a minimum
rated speed of at least 1800 RPM and a maximum wheel diame-
ter of 6” .
• To loosen nuts holding the wheels, disconnect power and push
a wood wedge between the tool rest and the wheel to keep the
shaft from turning. The threads on the right side of the grinder
(facing unit) are right hand; threads on the left side are left
hand. Tighten nuts securely before operating the grinder.
• For grinding efficiency, wheels should be dressed periodically,
especially if they become clogged from grinding soft metals.
