CAUTION:
The wheel guard must be fitted on the tool so that
•
the closed side of the guard always points toward
the operator.
Mount the wheel guard with the protrusion on the wheel
guard band aligned with the notch on the bearing box.
Then rotate the wheel guard around 180 degrees. Be
sure to tighten the screw securely.
To remove wheel guard, follow the installation procedure
in reverse.
Installing or removing depressed center
grinding wheel/Multi-disc
010271
WARNING:
Always use supplied guard when depressed center
•
grinding wheel/Multi-disc is on tool. Wheel can
shatter during use and guard helps to reduce
chances of personal injury.
Mount the inner flange onto the spindle so that the
recess on the inner flange fits onto the two parallel flat
faces on the spindle. Then fit the wheel/disc on the inner
flange and screw the lock nut onto the spindle.
In case of mounting a wheel/disc thinner than 3mm,
place the lock nut so that the protrusion on the lock nut
faces outside. Otherwise place it so that the protrusion
on it fits into the inner diameter of the wheel/disc.
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.

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.
CAUTION:
After operation, always switch off the tool and wait
•
until the wheel has come to a complete stop before
putting the tool down.
