Installing or removing flex wheel (optional

accessory)

009434

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)

009435

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 saw blades. 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.

Grinding and sanding operation

009429

ALWAYS hold the tool firmly with one hand on housing

and the other on the side handle. Turn the tool on and

then apply the wheel or disc to the workpiece.

In general, keep the edge of the wheel or disc at an

angle of about 15 degrees to the workpiece surface.

During the break-in period with a new wheel, do not work

the grinder in the B direction or it will cut into the

workpiece. Once the edge of the wheel has been

rounded off by use, the wheel may be worked in both A

and B direction.

Operation with wire cup brush (optional

accessory)
