the other. After sharpening, be sure to balance the blade by removing additional material
from the heavy end. There are a number of inexpensive cone balances on the market for
this purpose. Unbalanced blades can cause serious crank shaft damage to your lawn
mower. Always remove spark plug wires from the mower before servicing the blades to
prevent accidental starting.
MAINTENANCE
WARNING: For your own safety, turn switch OFF and remove plug from power source
outlet before adjusting and maintaining your bench grinder. If power cord is worn, cut, or
damaged in any way, have it replaced immediately.
CARE OF GRINDING WHEELS
In normal use, grinding wheels may become cracked, grooved, rounded at the edges,
chipped, out of true or loaded with foreign material. CRACKED WHEELS SHOULD BE
REPLACED IMMEDIATELY, while any of the other conditions can be remedied with a
dressing tool (available at most hardware stores). New wheels sometimes require
dressing to make them round.
WHEEL REPLACEMENT
If you must replace a wheel be sure to obtain one with a safe rated speed at least as high
as the ‘NO LOAD’ RPM marked on your grinder’s nameplate and with a 1/2” center hole.
6” diameter wheel should be a maximum of 3/4” wide. Test new wheels for cracks and
maintain the existing sequence of retaining hardware. Be sure the tool is unplugged
before attempting repairs.
Your bench grinder will accept most polishing and buffing wheels available at dealers and
hardware stores.
WARNING: The use of any other accessories is not recommended and may result in
serious injury.
