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. (Dust Collection hose not included with
82061A).
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, 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 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
installed and grounded in accordance with all local codes and
ordinances. 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 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
replaced 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 4) 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
permitted 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 per-
manent electrical ground such as a properly grounded water
pipe, a properly 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.)
extension 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,
replace 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 5). Motor is assembled with approved, 3-conductor cord
to be used at 120/240 volts. Motor is prewired at the factory for
120 volts.
•To use the grinder with a 240V power supply, have a qualified
electrician rewire motor and attach a 240 volt, I5A three-prong
plug onto grinder line cord.
OPERATION
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
moving 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.
Overheating 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.
•Models 82061B, 82062B, 82071B and 82081B: Replacement
wheels should have a minimum rated speed of at least 3600
RPM.
•Model 82101A: Replacement wheels must have a minimum
rated speed of 1800 RPM.
•Maximum wheel diameter is 6” for 82061B and 82062B, 7” for
82071B, 8” for 82081B, and 10” for 82101A.
•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.
