English Adjusting the Sanding Belt Tracking (Fig. D)  WARNING: Keep hands, fingers and loose clothing away from moving belt. Hold the tool firmly with one hand, start motor and observe tracking of sanding belt. Use your other hand to adjust the belt tracking adjustment knob 7 to center the belt. If the belt runs outward, turn the tracking adjustment knob counterclockwise to make the belt run inward. If belt runs inward, turn the tracking adjustment knob clockwise to make the belt run outward. Belt life will be greatly increased by keeping the tracking adjustment set properly. To prevent the sanding belt from rubbing against the sander housing, keep the edge of the belt about 7/64" (2.7 mm) to 13/64" (5.1 mm) from the housing. Changing The Sanding Belt (Fig. E, F)  WARNING: To reduce the risk of serious personal injury, turn unit off and remove the battery pack before making any adjustments or removing/ installing attachments or accessories. An accidental start‑up can cause injury.  WARNING: To reduce the risk of injury, make sure belt is installed with arrows in proper direction of rotation. Failure to do this could result in the belt unraveling creating a hazardous condition. Pull the quick release lever 4 shown in Figure E to release the tension on the sanding belt. Pull the sanding belt 1 from the two rollers. Put the new 3" x 21" (75 mm x 533 mm) sanding belt in position on the front and rear rollers (Figure F). Ensure that the arrows on the sanding belt and on your belt sander are pointing in the same direction. Use one hand to hold the unit and use the other hand to push the lever to the rear to tension the sanding belt. Dust Extraction (Fig. G)  WARNING: Risk of dust inhalation. To reduce the risk of personal injury, ALWAYS wear an approved dust mask. A dust extraction port 8 is supplied with your tool. The dust extraction port allows you to connect the tool to an external dust extractor, either using the AirLock™ system, or a standard 35 mm dust extractor fitment.  WARNING: ALWAYS use a vacuum extractor designed in compliance with the applicable directives regarding dust emission when sanding wood. Vacuum hoses of most common vacuum cleaners will fit directly into the dust extraction outlet. Fitting and Removing the Dustbag (Fig. H) • Fit the dustbag 15 over the dust extraction port 8 . • To remove the dustbag, pull it off the dust extraction port. Fitting and Removing the Swivel Dust Adapter (Fig. I) • Fit the swivel dust adapter 16 into the dust extraction port 8 . An external dust extractor, either using the AirLock™ system, or a standard 35 mm dust extractor fitment can then be attached to the swivel dust adapter. • To remove the swivel dust adapter, pull it out of the dust extraction port. OPERATION  WARNING: To reduce the risk of serious personal injury, turn unit off and remove the battery pack before making any adjustments or removing/ installing attachments or accessories. An accidental start‑up can cause injury. Installing and Removing the Battery Pack (Fig. J)  WARNING: Ensure the tool/appliance is in the off position before inserting the battery pack.
