OPERATION WARNING: Collected sanding dust from sanding surface coatings such as polyurethanes, linseed oil, etc., can self-ignite in the sander dust collection bag or elsewhere and cause fire. To reduce the risk of fire, always empty the dust bag frequently (10-15 minutes) while sanding and never store or leave a sander without totally emptying its dust bag. Also follow the recommendations of the coatings manufacturers. Follow these steps to empty the dust collection bag. Unplug the sander. Remove the dust collection bag from the sander. Unzip the dust bag. Shake out the dust. Zip up the dust bag. Replace the dust collection bag. NOTE: Periodically, you should turn the dust bag inside-out and thoroughly clean it. TURNING THE SANDER ON/OFF See Figure 7, page 12. To turn on the sander: Depress the switch trigger. To turn off the sander: Release the switch trigger. LOCKING ON THE SANDER See Figure 7, page 12. The lock-on feature allows you to lock the switch trigger in the ON position. Locking the switch trigger on allows you to operate the sander for extended periods of time. If you have the lock-on feature engaged during use and the sander is accidentally disconnected from the power supply, disengage the lock-on feature immediately. Also, do not lock the switch trigger if you might need to suddenly stop the sander. WARNING: Before connecting the sander to a power supply, make sure it is not in the locked-on position. Failure to do so could result in accidental starting of the tool resulting in serious injury. To lock-on the sander: Depress the switch trigger. Push in the lock-on button. Release the switch trigger. Release the lock-on button. NOTE: To release the lock, completely squeeze and release the switch trigger. OPERATING THE SANDER See Figure 8, page 12. Secure the work to prevent it from moving under the sander. WARNING: Unsecured work could be thrown towards the operator causing injury. Turn the sander on and let the motor reach its maximum speed before placing the sander on the work surface. Lower the sander to the work surface with a slight forward motion. Move the sander slowly over the work surface, using the rear handle to control the sander and the front handle to guide the sander. NOTE: Allowing the sander to remain in one place will result in an uneven surface. WARNING: Keep a firm grip on the sander with both hands at all times. Failure to do so could result in loss of control leading to possible serious injury. The sander is designed to provide the proper weight on the sanding belt. Excessive pressure will result in the following: Uneven work Clogged sanding belts Premature sanding belt wear Possible motor burnout Irregular sanding belt tracking PROPER HAND PLACEMENT See Figure 9, page 12. For ease of operation and maintaining proper control, the sander has a front handle and a rear handle. These handles allow two-handed operation, which aids in maintaining control, keeping the sanding area level with the workpiece, and keeping hands clear of the sanding belt. When operating the sander, always hold the front handle with your left hand and the rear handle with your right hand. WARNING: Keep hands and fingers clear of moving sanding belt, front idler roller, and drive roller assembly. Failure to do so could result in serious personal injury. 8 - English
