Installing or removing abrasive paper 
(Fig. 2 & Fig. 3)

Open the paper clamp by raising the lever from the 
locking port. Insert the paper end into the clamping part. 
Align the paper edges even and parallel with the sides of 
the base. Bending the paper beforehand makes 
installation 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.
