Grinding wheel and guard must be securely
attached as described in this operating manual
before connecting the grinder to a power source.

Grinding wheels must be stored in a dry place.

Before attaching the grinding wheel, inspect it for
visible defects. If cracked, chipped, or warped, do
not install it.

Do not overtighten the clamp nut on the grinding
wheel. Excessive tightening can cause the wheel
to crack during operation

Make sure that the guard is in good condition and
securely installed before operating grinder.

Do not clamp the grinder in a vise or use as a fixed
grinder.

Never turn on the grinder with the grinding wheel
or any rotating parts touching the workpiece.

Use only grinding wheels in compliance with ANSI
standard B7.1 and rated greater than 11,000 rpm.

Do not use the grinder if the disc flange or clamp
nut is missing or if the spindle is bent.

Always hold the grinder securely with two hands
while working and at all times when it is running.

Never cover the air vents in the motor housing
with your hands while operating the grinder.

Hold the tool away from your body while it is
running. Keep your hands away from the abrasive
attachments.

Dust and waste materials should not be allowed to
build up in the workshop. Hot metal sparks could
start a fire.

Do not remove the soft paper in the center of the
grinding wheel. NOTE: If this paper has been
previously removed, insert some soft rubber or
paper between the grinding wheel and disc flange.

Do not enlarge or alter the center hole of the
grinding wheel as this could result in breaking it.

Use only the normal grinder surface. Never use
the side or upper surfaces for cutting.

KEEP THE TOOL AND ITS HANDLE DRY,
CLEAN, AND FREE FROM OIL AND GREASE.
Always use a clean cloth when cleaning. Never
use brake fluids, gasoline, petroleum-based
products, or any strong solvents to clean your tool.

RULES FOR SAFE OPERATION FOR GRINDERS

The operation of any grinder can result in foreign objects being thrown into your eyes,
which can result in severe eye damage. Before beginning power tool operation, always
wear safety goggles or safety glasses with side shields and a full face shield when
needed. We recommend Wide Vision Safety Mask for use over eyeglasses or standard
safety glasses with side shields.

WARNING:

WARNING:

If any parts are missing, do not operate your grinder until
the missing parts are replaced. Failure to do so could
result in possible serious personal injury.
