HEARING PROTECTION IS RECOMMENDED Hearing protection should be used when the noise level exposure equals or exceeds an 8 hour time- weighted average sound level of 85 dBA. Process noise, reflective surfaces, other tools being operated nearby, all add to the noise level present in your work area. If you are unable to determine your noise level exposure, we recommend the use of hearing protection. WEAR RESPIRATORY PROTECTION It is advisable, when using this tool for extended periods of time, to wear a protective mask. This will help prevent the inhalation of the fine dust produced while using this tool. Prolonged breathing of dust particles may lead to future respiratory problems. Some dust created by power sanding, sawing, grinding, drilling and other construction activities contain chemicals known to cause cancer, birth defects or reproductive harm. Some examples of these chemicals are: • Lead from lead-base paints • Crystalline Silica from bricks, cement and other masonry products. • Arsenic and Chromium from chemically treated lumber. Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals, work in a well ventilated area and work with approved safety equipment such as those dust masks that are specially designed to filter out microscopic particles. 1/2-Inch Power Ratchet Wrench Operator's Manual AVOID PROLONGED EXPOSURE TO VIBRATION Pneumatic tools can vibrate during use. Prolonged exposure to vibration or very repetitive hand and arm movements, can cause injury. Stop using any tool if discomfort, tingling feeling or pain occurs. You should consult your physician before resuming use of the tool. CAUTION 90 PSIG MAXIMUM Designed to operate at an air pressure of 90 pounds per square inch gauge pressure (90 PSIG) maximum, at the tool. Use of higher air pressure can, and may cause injury. Also use of higher air pressure places the internal components under loads and stresses they were not designed for, causing premature tool failure. NOTE: The air supply should be clean and dry, preferably lubricated. For best results drain the moisture from your compressor daily. USE ONLY POWER SOCKETS AND ACCESSORIES Sockets and accessories used shall be of the power socket type. Always check sockets, retainers and drives regularly for wear or damage and replace when necessary. 1/2-Inch Power Ratchet Wrench Operator's Manual Installation Designed to operate on 90 PSIG, lower pressure (below 90 PSIG) will reduce performance of the tool while higher air pressure (over 90 PSIG) raises the performance of the tool beyond its rated capacity and could cause serious damage to tool and user. Always use clean dry air. Excessive moisture and dirt will greatly reduce the life of any air motor. We recommend the installation of an in-line filter-regulator-lubricator as close to the tool as possible. A 3/8" air hose is required up to a length of 8 ft. If more length is required a 1/2" air hose should be connected to the 3/8" hose to ensure the tool has the necessary air supply. Be sure all hoses and fittings are the correct size and tightly secured. RECOMMENDED AIR LINE SET-UP 1/2-Inch Power Ratchet Wrench Operator's Manual Operation PRE-OPERATION: Before the tool is connected to the air supply, clear the air hose of accumulated dust and moisture. Before removing a tool for service or changing sockets, make sure the air line is shut-off and drained of air. This will prevent the tool from operating if the throttle is accidently engaged. OPERATION: This wrench is equipped with a lever throttle which allows the operator to vary the speed. Direction control is located on the back of the ratchet head. Initial tightening and loosening of fasteners should be done manually with ratchet used as a hand tool. Nuts may then be run on and off with relative ease. Keep sockets firmly against work surface when running tool to avoid jarring the sockets from the anvil or rounding the fastener heads. Excessive torque leverage above tool specifications will result in premature gear wear. CAUTION: HAND TOOL SOCKETS CAN BREAK CREATING A HAZARD FROM FLYING PIECES. ALWAYS CHECK SOCKETS, RETAINERS AND DRIVES REGULARLY FOR WEAR OR DAMAGE AND REPLACE WHEN NECESSARY. THE DESIGN OF THIS TOOL REQUIRES THAT EXTRA CARE MUST BE TAKEN WHEN USING THE RATCHET IN TIGHT AREAS. HANDS AND FINGERS SHOULD NOT BE HELD BETWEEN TOOL AND WORK SURFACE. PERSONAL INJURY MAY RESULT. Maintenance LUBRICATION: An automatic in-line filter-regulator-lubricator is recommended as it increases tool life and keeps the tool in sustained operation. The in-line lubricator should be regularly checked and filled with John Deere AT-4003 air tool oil. Proper adjustment of the in-line lubricator is performed by placing a sheet of paper next to the exhaust ports and holding the throttle open approximately 30 seconds. The lubricator is properly set when a light stain of oil collects on the paper. Excessive amounts of oil should be a...
