Safety warnings General air tool warnings 1. Read and understand this entire manual before attempting assembly or operation. 2. Read and understand all warnings posted on the tool and in this manual. Failure to comply with all of these warnings may cause serious injury. 3. Replace warning labels if they become obscured or removed. 4. Do not use this tool for other than its intended use.
25. Give your work undivided attention. Looking around, carrying on a conversation and “horse-play” are careless acts that can result in serious injury. 26. Do not force a tool or attachment to do a job for which it was not designed. The right tool will do the job better and more safely. 27. Repetitive motions and/or exposure to constant vibration can be harmful to hands and arms. Take frequent breaks and relax hands during extended operation. Change posture to avoid discomfort or fatigue. 28.

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. Rotate air regulator dial to preferred setting. Regulator settings are for reference only and do not indicate specific power settings. 5.
Maintenance 4. Drain water from air compressor tank daily, as well as any condensation from air lines. Water in the air line may enter the tool and cause damage. 5. Change filters on the air system on a regular basis. 6. Air-line pressure may be increased accordingly to compensate for extra-long air hoses (usually over 25 feet). Inside diameter of hose should be minimum 3/8-inch. Lubrication The impact wrench should be lubricated daily (or before each use) with air tool oil through the air inlet.
When using multiple hoses, air hoses should be larger than leader hose. Join multiple hoses directly, rather than with quick connect fittings which may cause pressure drops and tool power reduction. Use anti-whip devices across hose couplings to prevent hose from whipping in the event of a hose failure or coupling disconnect. 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).
