WARNING:

• 

When using a depressed center grinding wheel/

Multi-disc, flex wheel, wire wheel brush, cut-off 

wheel or diamond 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 opera-

tor according to work. Be sure to tighten the screw securely.

To remove wheel guard, follow the installation proce-

dure in reverse.

 Lever

Loosen the lever on the wheel guard after loosening the screw. 

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 to the position shown in the figure. 

Tighten the lever to fasten the wheel guard. If the lever is too 

tight or too loose to fasten the wheel guard, loosen or tighten 

the screw to adjust the tightening of the wheel guard band.

To remove wheel guard, follow the installation procedure in reverse.

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. 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 pres

-

sure. 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, espe

-

cially 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

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.
