The following recommendations will help you
sharpen specific tools:
TWIST DRILL BITS
Drill bits are best sharpened on a sharpening
jig (available at most hardware stores). Begin
on one side of the point at the existing angle,
then twist the bit while maintaining contact
with the grinding surface. Sharpen only the
tip.
This technique requires considerable practice,
so take your time and make a few "dry runs"
first with the grinder off. Be sure to maintain
the original cutting edge angle as this is impor-
tant to the efficiency of your bits. One work
rest has a V-groove angled to fit most drill bits.
LAWN MOWER BLADES
Lawn mower blades are usually sharpened on
only one edge and dressed up slightly on the
other. Perform this sharpening process on both
cutting ends of the blade. After sharpening, be
sure to balance the blade by removing addi-
tional material.
Caution: an unbalanced lawn mower blade
may cause excessive vibration which will dam-
age the lawn mower.
CHISELS AND SCREWDRIVER BLADES
When sharpening chisels and screwdrivers,
work rest should support the chisel at the cor-
rect angle against the wheel.
WHEEL REPLACEMENT
If you must replace a grinding wheel, be sure
to obtain one with a safe rated speed greater
than the "no load speed" r/min marked on the
data plate of the grinder.
To replace the grinding wheel, remove the
wheel cover by loosening the screws. Loosen
the wheel nut in a clockwise direction for the
left side and a counterclockwise direction for
the right side. Remove the outer flange and
grinding wheel. To install a new grinding
wheel, reverse the above procedure. Be sure
the grinding wheel and outer flange are prop-
erly seated on the spindle shaft.

MAINTENANCE
WARNING: when servicing, use only iden-
tical replacement parts. Use of any other part
may create a hazard or cause product damage.
GENERAL
Keep the bench grinder clean. Remove dust
from working parts and beneath the grinder
frequently. Make sure the bench grinder oper-
ates properly. Check screws, nuts, and bolts for
tightness.
Servicing requires extreme care and knowl-
edge and should be performed only by a quali-
fied service technician. For service we suggest
you return the tool to your nearest authorized
service center for repair. When servicing, use
only identical replacement parts.
