PRACTICAL OPERATING PROCEDURES

CAUTION: Never apply water or grinding fluid when sanding.
This could result in electrical shock.
1. Switching the sander ON and OFF
By pulling the trigger and pushing the stopper, the switch will remain ON even
when the trigger is released, promoting continuous, efficient operation. By
pulling the trigger again, the stopper is released and the switch is turned OFF.
CAUTION: Never turn the power switch ON when the sander is contacting
the surface to be sanded. This is necessary to preclude damage
to the material. The same applies when switching the power OFF.
2. How to hold the orbital sander
While gripping the knob with one hand and the handle with the other, lightly
press the sander against the surface to be sanded so that the sanding paper
uniformly contacts the surface. DO NOT apply excessive pressure to the sander
while sanding. Excessive pressure may cause overload of the motor, reduced
service life of the sanding paper, and lower sanding or polishing efficiency. Also,
while sanding or polishing, never cover the ventilation port on the upper motor
housing. This could cause overheating and subsequent damage to the tool.
3. How 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 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.
