OPERATION

ALWAYS WEAR SAFETY GOGGLES OR SAFETY GLASSES WITH SIDE SHIELDS WHEN OPERATING YOUR SANDER. To adjust sanding belt, connect sander to power supply. Place sander in upside down position as shown in Figure 7. NOTE: This position is for adjustments only. The sander is not in an operating position. Pull switch trigger and release immediately. Observe tracking of sanding belt. If the sanding belt runs inward, turn the tracking screw clockwise. If the sanding belt runs outward, turn the tracking screw counterclockwise. This should be done until you are sure belt will not run off sander, or come in contact with internal parts. After installing a new sanding belt, it may become necessary to change the adjustment several times until the belt becomes pliable.

WARNING: IF SANDING BELT BEGINS TO WEAR EXCESSIVELY ON THE INNER EDGE, READJUST TRACKING SCREW. IT IS ADJUSTED TOO FAR INWARD AND THE SANDING BELT IS RUBBING AGAINST INTERNAL PARTS.

When you are sure the belt will not rub against internal parts, start your sander and fine adjust the tracking screw until the belt stablizes. See Figure 8.

When correctly adjusted, the outer edge of the belt will be even with the outer edge of the base of your sander. Belt life will be greatly increased if a few seconds are spent adjusting the belt tracking.

WARNING: KEEP HANDS AND FINGERS AWAY FROM MOVING SANDING BELT. ANY PART OF YOUR BODY COMING IN CONTACT WITH MOVING BELT COULD RESULT IN SERIOUS INJURY. DO NOT WEAR LOOSE CLOTHING OR JEWELRY WHEN OPERATING YOUR SANDER. THEY COULD GET CAUGHT IN MOVING PARTS AND FOREIGN OBJECTS COULD GET THROWN AWAY FROM SANDER CAUSING INJURY.

TO OPERATE

Clamp or otherwise secure the work to prevent it from moving under your sander.

WARNING: UNSECURED WORK COULD BE THROWN BACK TOWARD OPERATOR CAUSING INJURY.

Before placing sander on work surface, squeeze the trigger switch and let the motor reach its maximum speed, then lower your sander to the work surface with a slight forward motion. Using the rear handle to control your sander and the front handle only to guide it, move it slowly over the work. See Figure 9. Allowing your sander to remain in one place will result in an uneven surface.

WARNING: KEEP A FIRM GRIP ON SANDER WITH BOTH HANDS AT ALL TIMES. FAILURE TO DO SO COULD RESULT IN LOSS OF CONTROL LEADING TO POSSIBLE SERIOUS INJURY.

Your sander was designed to provide the proper weight on the sanding belt. Extra pressure will result in uneven work, clogged belts, and possible motor burnout. NOTE: The front roller of your sander was not designed for contour sanding. Sanding on the front roller could cause irregularity in sanding belt tracking.

Use a coarser belt when heavy cutting is desired, not heavy pressure. The importance of this cannot be over-emphasized. The weight has been built into the tool to give the most efficient pressure at the proper location.
