To install the abrasive paper, raise the lever to open the 
clamper. Insert the paper end into the clamper. aligning 
the paper edges even and parallel with the sides of the 
base. And then return the lever to its original position. 
(Prebending paper makes attachment easier.) 
Repeat the same process for the other end of the base, 
maintaining the proper paper tension. 

After inserting the paper, make sure the clamper holds it 
securely. Otherwise the paper will be loose and subject 
to slippage, resulting in uneven sanding operation. 

OPERATION 

Sanding operation 

 

CAUTION: 

• 

Never run the tool without the abrasive paper. You 
may seriously damage the pad. 

• 

Never force the tool. Excessive pressure may 
decrease the sanding efficiency, damage the 
abrasive paper and/or shorten tool life. 

• 

Do not block motor bent with your finger or hand. 

   

013270 

Hold the tool firmly. Turn the tool on and wait until it 
attains full speed. Then gently place the tool on the 
workpiece surface. A finishing sander is generally used 
to remove only a small amount of material at a time. 
Since the quality of the surface is more important than 
the amount of stock removed, do not bear down on the 
tool. Keep the base flush with the workpiece at all times.   
You can put a high polish on furniture surfaces by using 
a cloth under the tool.

the like. Discoloration, deformation or cracks may
