ALWAYS hold the tool firmly with one hand on rear 
handle 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) 

 

CAUTION: 

• 

Check operation of brush by running tool with no 
load, insuring that no one is in front of or in line with 
brush. 

• 

Do not use brush that is damaged, or which is out of 
balance. Use of damaged brush could increase 
potential for injury from contact with broken brush 
wires.

Unplug tool and place it upside down allowing easy 
access to spindle. Remove any accessories on spindle. 
Mount wire cup brush onto spindle and tighten with 
supplied wrench. When using brush, avoid applying too 
much pressure which causes over bending of wires, 
leading to premature breakage. 

Operation with wire wheel brush (optional 
accessory) 

 

CAUTION: 

• 

Check operation of wire wheel brush by running 
tool with no load, insuring that no one is in front of 
or in line with the wire wheel brush. 

• 

Do not use wire wheel brush that is damaged, or 
which is out of balance. Use of damaged wire 
wheel brush could increase potential for injury from 
contact with broken wires. 

• 

ALWAYS use guard with wire wheel brushes, 
assuring diameter of wheel fits inside guard. Wheel 
can shatter during use and guard helps to reduce 
chances of personal injury.

access to spindle. Remove any accessories on spindle. 
Thread wire wheel brush onto spindle and tighten with 
the wrenches. 
When using wire wheel brush, avoid applying too much 
pressure which causes over bending of wires, leading to 
premature breakage. 

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 European 
countries, when using a diamond wheel, the 
ordinary guard can be used.) 

• 

NEVER use cut-off wheel for side grinding. 

• 

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. 

• 

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. 

• 

During cutting operations, never change the angle 
of the wheel. Placing side pressure on the cut-off 
wheel (as in grinding) will cause the wheel to crack 
and break, causing serious personal injury. 

• 

A diamond wheel shall be operated 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.
