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.

1.

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

2.

Grinding wheels must be stored in a dry place.

3.

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

4.

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

5.

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

6.

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

7.

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

8.

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

9.

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

10.

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

11.

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

12.

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

13.

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

14.

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.

15.

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

16.

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