Installing or removing flex wheel
(optional accessory)
WARNING:
Always use supplied guard when flex wheel is on tool.
Wheel can shatter during use and guard helps to reduce
chances of personal injury.
Follow instructions for depressed center grinding wheel/
Multi-disc but also use plastic pad over wheel. See order of
assembly on accessories page in this manual.
Installing or removing abrasive disc
(optional accessory)
NOTE:
Use sander accessories specified in this manual. These
must be purchased separately.
Mount the rubber pad onto the spindle. Fit the disc on the
rubber pad and screw the lock nut onto the spindle. To
tighten the lock nut, press the shaft lock firmly so that the
spindle cannot revolve, then use the lock nut wrench and
securely tighten clockwise.
To remove the disc, follow the installation procedure in
reverse.
OPERATION
WARNING:
It should never be necessary to force the tool. The
weight of the tool applies adequate pressure. Forcing
and excessive pressure could cause dangerous wheel
breakage.
ALWAYS replace wheel if tool is dropped while grinding.
NEVER bang or hit grinding disc or wheel onto work.
Avoid bouncing and snagging the wheel, especially
when working corners, sharp edges etc. This can cause
loss of control and kickback.
NEVER use tool with wood cutting blades and other
sawblades. Such blades when used on a grinder
frequently kick and cause loss of control leading to
personal injury.
