Attaching and Care of Dust BAG

4.Release the trigger to stop the motor. Allow the tool to come to a COMPLETE STOP before turning it over and putting it down.

Attach the dust bag to the sander by pushing the dust bag tube into the sander vacuum housing (Fig. 4).

For the most efficient operation, empty the dust bag when it is approximately half full. Pull the dust bag straight out of the vacuum housing, unzip the rear of the bag, and shake out the dust. Every so often, turn the bag inside out and brush the accumulated dust from the inside.

Do not operate the tool without a dust bag or a dust collection system.

SELECTING AN ABRASIVE BELT

The principle abrasive materials used on belts for machine sanding are aluminum oxide and silicon carbide. Aluminum oxide is the softer of the two, but is tougher and more suited for woods and soft (non-ferrous) metals. Silicon carbide is extremely hard and is best suited for surfacing stone, marble, and glass.

Abrasives are classed as open-coated (with grits spaced apart), or closed- coated (with grits close together). Closed coatings provide hard, fast cutting action for hardwoods and dense metals, while open coatings are more suited to soft materials and painted surfaces.

To obtain the best finish, start with a “COARSE” grade of abrasive and change to “MEDIUM” and then to“FINE” as work progresses.

GENERAL SANDING

SECURE THE WORK and maintain a FIRM GRIP on the sander. Friction between the sanding belt and the work will tend to move the work backward and the sander forward.

ALWAYS be sure that the switch is OFF before connecting the tool to the power source.

1.Hold the sander off the work before starting the motor.

2.Lower the sander to the work, touching the rear part of the belt first. Level the machine when moving it forward.

3.Guide the machine over the work in overlapping strokes. Allow the sander to do the work.

4.Avoid applying excessive pressure. The weight of the machine is usually sufficient for a fast smooth finish. A slight increase in pressure may speed removal of material, but too much pressure will slow the motor and decrease removal.
