TO ATTACH PRESSURE SENSITIVE ADHESIVE SANDING DISC REMOVING SANDING DISC BEFORE STORAGE Do not store your sander with the sanding disc installed. Heat generated from sanding causes the pressure sensitive adhesive to flow and form a tight bond between the backing pad and sanding disc. See Figure 3. Removing the sanding disc soon after you have finished a sanding operation avoids letting the adhesive set up.

For more efficient operation, empty dust bag when no more than half full. This will permit the air to flow through the bag better.
ATTACHING SANDER TO VACUUM _ See Figures 8 and 9. WARNING: When sander is not connected to vacuum, always reinstall dust bag assembly back on sander.

Do not force. The weight of the unit supplies adequate pressure, so let the sanding disc and sander do the work. Applying additional pressure only slows the motor, rapidly wears sanding disc and greatly reduces sander speed. Excessive pressure will overload the motor causing possible damage from motor overheating and can result in inferior work. Any finish or resin on wood may soften from the frictional heat.
BRUSH REPLACEMENT EXTENSION See Figure 12. • The use of any extension cord will cause some loss of power. To keep the loss to a minimum and to prevent toot from overheating, use an extension cord that is heavy enough to carry the current the tool will draw. Unplug your sander. _lb CORDS WARNING: Failure to unplug your sander could result in accidental starting causing possible serious personal injury. A wire gage size (A.W.G.
