To remove the disc, follow the installation procedure in 

reverse.

NOTE:

 Use sander accessories specified in this man

-

ual. These must be purchased separately.

OPERATION

WARNING:

 

It should never be necessary to 

force the tool.

 The weight of the tool applies ade

-

quate pressure. Forcing and excessive pressure 

could cause dangerous wheel breakage.

WARNING:

 

ALWAYS replace wheel if tool is 

dropped while grinding.

WARNING:

 

NEVER bang or hit grinding disc 

or wheel onto work.

WARNING:

 

Avoid bouncing and snagging the 

wheel, especially when working corners, sharp 

edges etc.

 This can cause loss of control and kickback.

WARNING:

 

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:

 

Never switch on the tool when it 

is in contact with the workpiece, it may cause an 

injury to operator.

CAUTION:

 

Always wear safety goggles or a 

face shield during operation.

CAUTION:

 

After operation, always switch off 

the tool and wait until the wheel has come to a 

complete stop before putting the tool down.

CAUTION:

 

ALWAYS hold the tool firmly with one 

hand on housing and the other on the side grip (handle).

Grinding and sanding operation

15°

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° to the workpiece surface.

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

work the grinder in forward direction or it may cut into 

the workpiece. Once the edge of the wheel has been 

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

forward and backward direction.

Operation with abrasive cut-off / 

diamond wheel

Optional accessory

WARNING:

 

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 some European countries, when using a diamond 

wheel, the ordinary guard can be used. Follow the 

regulations in your country.)

WARNING:

 

NEVER use cut-off wheel for side 

grinding.

WARNING:

 

Do not "jam" the wheel or apply 

excessive pressure. Do not attempt to make an 

excessive depth of cut.

 Overstressing the wheel 

increases the loading and susceptibility to twisting 

or binding of the wheel in the cut and the possibility 

of kickback, wheel breakage and overheating of the 

motor may occur.

WARNING:

 

Do not start the cutting operation 

in the workpiece. Let the wheel reach full speed 

and carefully enter into the cut moving the tool 

forward over the workpiece surface.

 The wheel 

may bind, walk up or kickback if the power tool is 

started in the workpiece.

WARNING:

 

During cutting operations, never 

change the angle of the wheel.

 Placing side pres-

sure on the cut-off wheel (as in grinding) will cause 

the wheel to crack and break, causing serious per-

sonal injury.

WARNING:

 

A diamond wheel shall be oper-

ated perpendicular to the material being cut.

Mount the inner flange onto the spindle.

Fit the wheel / disc on the inner flange and screw the 

lock nut onto the spindle.
