English OPERATING PROCEDURES CONTINUED SHUT-DOWN (FIG. 1, PG. 2) • Release the trigger to stop the tool. • Always disconnect air supply when changing sandpaper pads. • When job is completed, turn off the air compressor and store the air tool after lubrication. Tips • Begin sanding with an abrasive grit sandpaper coarse enough to remove the high spots. Progress to a finer grit sandpaper until the desired finish is obtained. • Never change from coarse grit sandpaper to a very fine grit sandpaper, always progress gradually to the finer grit. OPERATING INSTRUCTIONS • Select a suitable abrasive disc and make sure that it is fixed securely to the tool. • Connect to suitable air supply as recommended. • Apply the sander lightly to the work and allow the abrasive disc to cut. Take great care when sanding around sharp edges and surfaces to avoid the disc snagging i.e. the disc may be brought to an abrupt stop or considerably slowed, causing the tool to kick in the hands. NOTE: Use of safety glasses and a breathing mask is recommended. Sanding certain materials may create hazardous dust which may require special breathing equipment. Check before using the tool. Although the tool has a low noise level, the actual sanding process may cause a noise level such that ear protectors will be required. Safety gloves are recommended. Do not continue to use abrasive discs that are worn or clogged. Do not use undersized or oversized sanding discs. The disc should be no more than 1/4" larger in diameter than the pad, and not smaller than the pad. MAINTENANCE Lubrication Air tools require lubrication throughout the lifetime of the tools. The air motor and bearing uses compressed air to power the tool. The compressed air contains moisture that will rust the air motor and other parts in side of the tools, therefore lubrication is required daily. Failure to lubricate the air tool properly will dramatically shorten the life of the tool and will void the warranty CAUTION: This air tool requires lubrication BEFORE initial use, also before and after each additional use. To Lubricate The Air Tool Manually: 1. Remove any attachments on the air tool. 2. Disconnect the tool from the air supply source, place the air inlet face up. 3. Depress the trigger and place about 1 teaspoon (5cc.) of air tool oil into the air inlet. (Depressing the trigger will help circulate oil in the motor.) NOTE: Use SAE #10 weight oil if air tool oil is not available. 4. Connect the tool to an air source, cover the exhaust end with a towel and run for about 20 to 30 seconds. WARNING: Keep out of the reach of children. If taken internally, do not induce vomiting, call a doctor immediately. WARNING: Any excess oil in the motor is immediately expelled from the exhaust port. Always direct exhaust port away from people or objects. Storage: The air tool must be lubricated before storing. Follow the "Lubrication" instruction with exception of step 4. 14
