IMPORTANT: Connecting a quick-change coupling directly to the tool is not recommended, as vibration may cause the connection to fail. Instead, add a leader hose and install any quick-change couplings farther down the line. 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. 3. Rotate chuck counterclockwise by hand to open chuck jaws.
4. When finished operating drill, 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. Disconnect air. The drill has been pre-greased from the manufacturer, and it is generally unnecessary to grease the tool during its normal life. However, should the tool require future servicing, a grease fitting is supplied below the dead handle for lubricating the gears.
Lubrication Recycling 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. Protect the environment. Your tool contains materials which can be recovered or recycled. When its useful life has expired, please leave tool at a specialized facility. If greasing is required, use a grease that is highly water resistant for front case components on air impact wrenches, grinders and sanders.
