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. Make sure nut or bolt can withstand rated torque of ratchet wrench. To loosen nut or bolt: 1. Select reverse rotation. 2. Place socket over nut, and grip tool firmly with both hands. 3. Gently squeeze throttle lever.
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 ratchet wrench at low throttle without load for a few seconds to distribute the oil throughout tool. 4. When finished operating ratchet wrench, disconnect air hose. Wipe off housing with a dry cloth.
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.
