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. Box contents: 1 1 1 Ratchet wrench Operation and parts manual Warranty card Operation 4. Use flat blade screwdriver to rotate air regulator to desired speed: Clockwise decreases speed (Low range), counterclockwise raises speed (High range). 5.
Maintenance Excess air pressure and/or unclean air will shorten the tool’s life and may create a hazardous situation. Lubrication The ratchet wrench should be lubricated daily (or before each use) with air tool oil through the air inlet. During continual operation, it should be reoiled every 1 to 2 hours. This can be done with an in-line oiler, or manually. If done manually, proceed as follows: 1. Disconnect air hose from tool. 2. Place 4 or 5 drops of air tool oil into air inlet.
Air System Recommendations Lubrication Equip the air compressor intake with a replaceable air filter that can be easily cleaned. 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. Use safety shut-off valves so air flow can be stopped quickly in case of a line break. When using multiple hoses, air hoses should be larger than leader hose.
Troubleshooting JAT-310/312/313 Ratchet Wrenches Any disassembly of the tool should be done by qualified service personnel. For problems not addressed below, contact JET technical service at 800-274-6846. Problem Possible cause Remedy Tool will not start. Air valve closed or obstructed. Open valve; clear any obstructions.
