RANDOM ORBIT SANDER OPERATION WARNING: Never apply water or grinding fluid when sanding. This could result in electrical shock. 1. How to hold the random orbit sander While gripping the housing, lightly press the sander against the surface to be sanded so that the sanding paper uniformly contacts the surface, as shown in Fig. 6. DO NOT apply excessive pressure to the sander while sanding. Excessive pressure may cause overload of the motor, reduced service life of the sanding paper, and lowered sanding or polishing efficiency. 2. How to move the random orbit sander Move the sander by either moving it up and down or by moving it in circles while gradually progressing in a sideways direction. (Figs. 7 and 8) Fig. 6 Fig. 7 English 3. Switching the sander ON and OFF The power can be turned on by setting the lever to ON (1) and turned off by setting the lever to OFF (0). Fig. 8 NOTE: Never turn the power switch ON when the sander is contacting the surface to be sanded. This is necessary to preclude damage to the material. The same applies when switching the power OFF. CAUTION: . lmmediately after use, always turn the sander off and unplug it. . Since the sander may suck in dust and debris, be careful not to place it where there is much dust and debris when it is still spinning right after use. HOW TO INSTALL THE OPTIONAL ACCESSORIES WARNING: Be sure to switch power OFF and disconnect the plug to avoid accidents. . Mounting the polyester buff Since the attachment is a hook-and-loop type as with the sanding paper, the polyester buff can be mounted by just pressing it onto the pad (Fig. 9). Polyester buff Fig. 9 English MAINTENANCE AND INSPECTION WARNING: Be sure to switch power OFF and disconnect the plug from the receptacle during maintenance and inspection. 1. Emptying and cleaning the dust bag If the dust bag contains too much saw dust, dust collection will be affected. Empty the dust bag when it gets full. Remove the dust bag, open the fastener, and dispose of the contents. 2. Inspecting the sanding paper Since use of worn-out sanding paper will degrade efficiency and cause possible damage to the pad, replace the sanding paper as soon as excessive abrasion is noted. 3. Inspecting the screws Regularly inspect all screws and ensure that they are fully tightened. Should any of the screws be loosened, retighten them immediately.
