Before connecting the sander to a power supply, make sure it is not in turned on.
Failure to do so could result in accidental starting of the sander resulting in
possible serious injury.
6.1. Turning the sander ON and OFF.
6.1.1. To turn the sander ON, slide the switch to the 'I' position.
6.1.2. To turn the sander OFF, slide the switch to the 'O' position.
6.2. Variable Speed Control.
6.2.1. The variable speed control allows the sander to develop a
no load speed that can be adjusted from 600 to 12000 spm.
The variable speed control selector is located on the front of
the sander.
6.2.2. The speed can be set according to the sanding purpose or
work-piece's surface you will be using.
6.2.3. With the dial facing away from you, turn the dial clockwise
to increase speed for rough surfaces or for quick removal of
stock and anti-clockwise to decrease speed for the smaller, delicate sanding applications.
6.3. Operating the sander.
Always wear safety goggles and a dust mask.
Always hold the sander in front and away from your body.
The Pad Sander is designed for dry sanding only and under no circumstances
should it be used for wet sanding.
Always keep the dust extraction holes in the vibrating plate free of dirt or other
obstructions.
The Sander is not to be used for sanding Gypsum.
6.3.1. Turn on the sander, gradually lower the sander onto the work piece, and then move it
slowly over the work piece using small circular motions.
6.3.2. Ensure that the entire sandpaper surface is in contact with the work piece.
6.3.3. Let the sander do the work and do not apply addition pressure as this will only reduce the
efficiency of the motor and rapidly wear the sandpaper.
6.3.4. Excessive pressure can cause damage to the motor.
6.3.5. If you are using the sander over an extended period the motor may overheat. If this occurs,
turn the sander off and allow it to cool down.
