Removing or installing wheel CAUTION : Always be sure that the tool is switched off and unplugged before removing or installing the wheel. To remove the wheel, insert one hex wrench into the end of the spindle and another hex wrench into the end of the output shaft. Turn the hex wrench in the output shaft clockwise while securely hold- ing the hex wrench in the spindle so that the wheel cannot revolve. Pull the output shaft out from the wheel. Move the wheel slightly away from the spindle and remove the wheel from the tool. CAUTION: The output shaft has a left hand thread. To install the wheel, follow the removal procedures in reverse. When installing it, be sure to align the notches in the wheel with the pins on the spindle. Adjusting front roller The front roller allows you to apply uni- form pressure to the workpiece. To adjust the front roller, set the tool on a flat sur- face and loosen the wing nut. Adjust the front roller up or down until the clearance distance (D) is about 2 mm (5/64”).Tighten the wing nut securely. \ Front roller Connecting to dust collector (Optional accessory) The use of a dust collector makes sanding operations clean and dust collection easy. To connect a dust collector, open the dust port by sliding the cover plate up and in a clockwise direction. Attach the joint onto the dust port. Now a dust collector can be connected to this tool. CAUTION: When not using a dust collector, close the dust port opening with the cover plate. Switch action To start the tool, simply pull the trigger. Release the trigger to stop.
