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. 

MAINTENANCE 

 

CAUTION: 

• 

Always be sure that the tool is switched off and the 
battery cartridge is removed before attempting to 
perform inspection or maintenance. 

• 

Never use gasoline, benzine, thinner, alcohol or 
the like. Discoloration, deformation or cracks may 
result.
