3. How to move the orbital sander
For optimum operating efficiency, alternately move
the sander forward and backward at a constant
speed and balance.
4. After installing new sanding paper
Movement of the sander may tend to become
unsteady after new sanding paper has been in-
stalled, 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.
MAINTENANCE AND INSPECTION
1. Inspecting the sanding paper
Since use of worn-out sanding paper will degrade
efficiency and cause possible damage to the pad,
replace the sanding paper as soon as excessive
abrasion is noted.
2. 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. Fail-
ure to do so could result in serious hazard.
3. 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.
4. Servicing
Consult an authorized Service Center in the event
of power tool failure.
