OPERATION
■
Extended periods of sanding may tend to overheat
the motor. If this occurs, turn sander off and wait until
sanding disc comes to a complete stop, then remove
it from workpiece. Remove your hand from vent area,
remove sanding disc, then with your hand removed
from vent area, turn sander on and run it free without
a load to cool motor.
■
For detail sanding such as corners and crevices,
use the tip of the sanding pad with small back and
forth motions, as shown in (fig. 4).
WARNING
Do not contact the pad with your hands during
operation when the RO pad is used,the no load
speed is very high which may cause injuries.
EMPTYING THE DUST BAG (Fig. 12)
For more efficient operation, empty the dust bag when it
is no more than half full. This will permit the air to flow
through the bag better. Always empty and clean the dust
bag thoroughly upon completion of a sanding operation
and before placing the sander in storage.
WARNING
Collected sanding dust from sanding surface
coatings such as polyurethanes, linseed oil etc.
can self-ignite in your sander dust bag or
elsewhere and cause fire. To reduce the risk of
fire always empty your dust bag frequently
(10-15 minutes) while sanding and never store or
leave a sander without totally emptying its dust
bag. Also follow the recommendations of the
coatings manufacturers.
Follow these steps to empty the dust bag:
■
Unplug the sander.
WARNING
Failure to unplug the tool could result in
accidental starting causing possible serious injury.
■
Remove the dust bag from the sander.
■
Shake out the dust.
■
Reattach the dust bag to the sander.
For a more thorough cleaning of the dust bag, remove
dust bag from frame, as shown in figure 12 and shake
out dust. Replace dust bag over frame then install dust
bag assembly on sander.
