Installing or removing wheel guard

(For depressed center wheel, multi disc /

abrasive cut-off wheel, diamond wheel)

For tool with locking screw type wheel guard

(Fig. 4 & 5)

WARNING:

• When using a depressed center grinding wheel/Multi-

disc, flex wheel, wire wheel brush, cut-off wheel or dia-

mond wheel, the wheel guard must be fitted on the tool

so that the closed side of the guard always points

toward the operator.

• When using an abrasive cut-off / diamond wheel, be

sure to use only the special wheel guard designed for

use with cut-off wheels. (In European countries, when

using a diamond wheel, the ordinary guard can be

used.)

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 to such an angle that it can

protect the operator according to work. 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 (Fig. 6 & 7)

Mount the inner flange onto the spindle. Fit the wheel/

disc on the inner flange 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 wheel, follow the installation procedure in

reverse.

WARNING:

• Only actuate the shaft lock when the spindle is not

moving.

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 grind-

ing.

• 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 fre-

quently kick and cause loss of control leading to per-

sonal 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 (Fig. 8)

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 work-

piece. Once the edge of the wheel has been rounded off

by use, the wheel may be worked in both A and B direc-

tion.

Operation with abrasive cut-off / diamond wheel (optional accessory) (Fig. 9)

The direction for mounting the lock nut and the inner flange varies by wheel thickness.
