OPERATION (CONTINUED)
• A manual reset overload protector is located on the right side
of the base. If the protector breaks the circuit, wait at least 15
seconds and then push protector in to reset. Restart grinder by
pressing the ON button and selecting High or Low speed.
• 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.
• Use slower wheel speed when sharpening tempered tools.
Overheating will destroy the temper.
• When grinding at high speed, dip work into a coolant regularly
to prevent overheating. Overheating can weaken metals.

• 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
the 1 / " maximum gap cannot be maintained, the wheels
16
should be replaced.
• Replacement wheels should have a minimum rated speed of at
least 3600 RPM.
• Maximum wheel diameter is 6" for 82066 and 8" for 82086.
• 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.
Palmgren Grinding Wheel Dressers, Model 82901 are recom-
mended (See pages 9 and 11).
