Make sure that the switch is “OFF” and the power circuit voltage is the same as the voltage shown on the specification plate. Connect the tool to the power circuit. 2. Squeeze the trigger (A) Fig. 2 to start the motor. Release the trigger to stop the motor. 3. To allow the motor to run without constantly holding the trigger, press the trigger switch (A), push the lock button (B) Fig. 2, and release the trigger switch. 4. To release the lock button, squeeze the trigger and release. VARIABLE SPEED CONTROL (Models 360VS and 362VS Only) Models 360VS and 362VS have Variable Speed Control. The operating speed is adjustable between 1000 SFM (surface feet per minute) and 1500 SFM. Adjust the speed by turning the thumbwheel (C) Fig. 2. Thumbwheel position #1 provides the slowest operating speed (1000 SFM) while position #6 provides the fastest operating speed (1500 SFM). The speed can be changed with the motor running or not running.

To make sure that the belt is tracking correctly, do the following: Make sure that the trigger is in the “OFF” position before connecting the tool to the power circuit. 1. Turn the tool over, rest the tool on its front handle, and grasp the rear handle with your left hand . Rest your ring finger and little finger on the trigger (Fig. 3). 2. Start the motor by squeezing the trigger. 3. Turn the belt aligning screw (A) Fig. 3 in either direction until the edge of the belt is even with the outer edge of the rear rubber- covered pulley. The edge of the belt will extend beyond the edge of the front pulley. 4. Turn the motor “OFF” and allow the sander to come to a COMPLETE STOP before turning it right side up. ATTACHING AND CARE OF DUST BAG Models 360, 360VS, 362 and 362VS Depress the dust bag spring clips A Fig. 3 (A) Fig. 4, and place the dust bag spring (A) between the ridges on the spout (B). For most efficient operation, empty the dust bag when it is half full. To remove, squeeze the dust bag spring clips (A) and pull the bag straight up. 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. A B Fig. 4 Do not operate the sander without a dust bag or a dust collection hose. 11 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 WORKPIECE and maintain a FIRM GRIP on the sander. Movement of the sanding belt against the workpiece will try to move the work backward and/or the sander forward. Verify that the switch is “OFF” before connecting the sander to the power circuit. 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. 5. Work back and forth over a fairly wide area to obtain an even surface. 6. Do not let the tool tilt. The edge of the belt can make a deep cuts into the surface. 7. Do not pause in any one spot during the sanding operation. The belt will eat into the work and make the surface uneven. 8. Lift the tool from the work before turning the motor off. 9. Always be sure that the motor has completely stopped before putting the tool down. FAST SANDING ON ROUGH WORK To smooth a rough surface quickly, use a coarse grit abrasive belt. With the belt positioned diagonally across the grain, move the tool in the direction of the grain (Fig. 5). Overlap the strokes and cover the entire surface, working from both sides of the board (angle left and then angle right.) Smooth the surface by guiding the sander back and forth with the grain. Change the belt to a medium grit and follow the same procedure. Finish by thoroughly working the grain lengthwise. Change again to a fine Fig. 5 grit and repeat. Always finish sanding with the grain. 12 REMOVING OLD PAINT AND VARNISH Read and follow “ADDITIONAL SAFETY RULES FOR PAI...
