Open the paper clamp by raising on the lever to release 
from the locking port and then Insert the paper end into 
the clamping part, aligning the paper edges even and 
parallel with the sides of the base. (Bending the paper 
beforehand makes attachment easier). Once the paper 
is in place, return the lever to its original position. 
Repeat the same process for the other end of the base, 
maintaining the proper paper tension. 
After inserting the paper, make sure the clamping part 
hold it securely. Otherwise the paper will be loose and 
subject to slippage, resulting in uneven sanding 
operation. 

 

OPERATION 

Sanding operation 

   

007721 

 

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. 

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.   

 

MAINTENANCE 

 

CAUTION: 

• 

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

To maintain product SAFETY and RELIABILITY, repairs, 
carbon brush inspection and replacement, any other 
maintenance or adjustment should be performed by 
Makita Authorized Service Centers, always using Makita 
replacement parts.
