4. After installing new sanding paper
Movement of the sander may tend to become unsteady
after new sanding paper has been installed, because of
the new, coarse grain of the paper. This can be avoided
by slightly tilting the sander forward or backward during
sanding or polishing. Sander movement will become
steady as the sanding paper surface becomes properly
abraded.
MOUNTING THE OPTIONAL ACCESSORIES
1. Attaching a Sponge Pad (Velcro type) or a Stick-on
pad
Loosen the M4 × 10 screws (4) and remove the attached
pad. Next, attach a sponge pad (Velcro type) or a stick-
on pad.
CAUTION
Replace the pad only. Use the other parts without
removing them.
2. Attaching Velcro Type Sanding Paper or Stick-on
Type sanding Paper
Match the sanding paper's hole with the pad's hole and
strongly push the sanding paper with the palm of your
hand to fasten it securely in place.
3. Making a Hole in the Sanding Paper with the Punch
Plate (Fig. 6)
When using sanding paper without holes in it, punch
holes in it with the punch plate to improve dust collecting
capacity.

MAINTENANCE AND INSPECTION

1. Empting and cleaning the Dust Bag
If the dust bag contains too much saw dust, dust collection
will be aff ected. Empty the dust bag when it gets full.
Remove the dust bag, open the fastener, and dispose of
the contents.
2. Inspecting the sanding paper
Since use of worn-out sanding paper will degrade
effi ciency and cause possible damage to the pad,
replace the sanding paper as soon a excessive abrasion
is noted.
3. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws be
loose, retighten them immediately. Failure to do so could
result in serious hazard.
4. Maintenance of the motor
The motor unit winding is the very "heart" of the power
tool.
Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
5. Servicing
Consult an authorized Service Agent in the event of
power tool failure.
