Setup and Assembly Any missing parts or damage should be reported immediately to your JET® distributor. Do not use a damaged tool. Read this instruction manual thoroughly for operation, maintenance and safety instructions. 4. Remove protective cap from air inlet (Figure 2). If an in-line oiler is not being used, add 4 or 5 drops of air tool oil (not included) into the air inlet. 5. Blow out air line to remove any dirt or moisture, then connect air supply hose to tool. Set air pressure to 90 psi.
NOTE: Air tool oil not provided; it is available at most major hardware and tool stores. SAE #10 oil or sewing machine oil may be used as a substitute. Do not use detergent oil. 3. Re-connect air. Run grinder at low throttle without load for a few seconds to distribute the oil throughout tool. 4. When finished operating grinder, disconnect air hose. Wipe off housing with a dry cloth. Place 4 or 5 drops of air tool oil into air inlet; re-connect air and run tool for a few seconds to distribute the oil.
Always use moisture traps at the compressor for the main distribution line. Use moisture traps and in-line oilers on each downline that is to be used for air tools. (See Figure 2). Place oiler as close to air tool as possible for best lubrication. Lubrication Use a light oil containing rust inhibitors, such as SAE #10. Many JET air tools have integral oil reservoirs, which should be kept filled when in-line oilers are not used.
