Always use hearing protection as recommended by your employer an OSHA regulations while using this tool (users and bystanders). • Keep the tool in efficient operating condition. • Operators and maintenance personnel must be physically able to handle the bulk, weight and power of this tool. • Air under pressure can cause severe injury. Never direct air at yourself or others. Always turn off the air supply, drain hose of air pressure and detach tool from air supply before installing, removing or adjusting any accessory on this tool, or before performing any maintenance on this tool. Failure to do so could result in injury. Whip hoses can cause serious injury. Always check for damaged, frayed or loose hoses and fittings, and replace immediately. Do not use quick detach couplings at tool. See instructions for correct set-up. • Keep tool out of reach of children. • Air powered tools can vibrate in use. Vibration, repetitive motions or uncomfortable positions over extended periods of time may be harmful to your hands and arms. Discontinue use of tool if discomfort, tingling feeling or pain occurs. Seek medical advice before resuming use. • Slipping, tripping and/or falling while operating air tools can be a major cause of serious injury or death. Be aware of excess hose left on the walking or work surface. • Place the tool on the work before starting the tool. Do not point or indulge in any horseplay with this tool. • Keep body working stance balanced and firm. Do not overreach when operating the tool. • Note direction of rotation BEFORE operating this tool. • Anticipate and be alert for sudden changes in motion during start up and operation of any power tool. • Do not carry tool by the hose. Protect the hose from sharp objects and heat. • Tool shaft may continue to rotate briefly after throttle is released. Avoid direct contact with accessories during and after use. Gloves will reduce the risk of cuts or burns. • Keep away from rotating end of tool. Do not wear jewelry or loose clothing. Secure long hair. Scalping can occur if hair is not kept away from tool and accessories. Choking can occur if neckwear is not kept away from tool and accessories. • Do not use (or modify) the tool for any other purpose than that for which it was designed without consulting the manufacturer's authorized representative. • Impact wrenches are not torque control devices. Fasteners with specific torque requirements must be checked with suitable torque measuring devices after installation with an impact wrench. • Use only impact sockets and accessories on this tool. Do not use hand sockets and accessories. • Use accessories recommended by Sunex Tools. • Do not lu bri cate tools with flam ma ble or vol a tile liq uids such as ker o sene, die sel or jet fuel. • This tool is not insulated against electric shock. • This tool must not be used in explosive atmospheres. • Servicing and repairs should only be made by an authorized service center. • Do not force tool beyond its rated capacity. • Do not remove any labels.

Wash hands thoroughly after handling. • Failure to heed these warnings may result in serious or fatal personal injury and/or property damage.

3 07/01/16 OPERATION Always turn off the air supply, drain hose of air pressure and detach tool from air supply before installing, removing or adjusting any part or accessory on this tool, or before performing any main- tenance on this tool. This im pact wrench is rated at 3/8" and 1/2" USS bolt size. Rat ing must be down grad ed for spring U bolts, tie bolts, long cap screws, double depth nuts, badly rust ed conditions and spring fas ten ers as they absorb much of the impact power. When possible, clamp or wedge the bolt to prevent springback. Soak rusted nuts in pen e trat ing oil and break rust seal before removing with im pact wrench. If nut does not start to move in three to five sec onds, use a larger size impact wrench. Do not use impact wrench be yond rated ca pac i ty as this will dras ti cal ly reduce tool life. The reversing lever is used to change the direction of the tool. When the valve is pushed to the left, the tool is in a for ward or right hand direction. When the valve is pushed to the right, the direction is reverse or left hand. NOTE: Actual torque on a fastener is directly related to joint hard- ness, tool speed, condition of socket and the time the tool is allowed to impact. Use the simplest possible tool-to-socket hook up. Every connection absorbs energy and reduces power. WARNING: Use only impact sockets and accessories on this tool. Do not use hand sockets and accessories. INSTRUCTION MANUAL This product is designed to tighten or loosen threaded fasteners. No other use is permitted. AIR SUPPLY REQUIREMENTS Tools operate on a wide range of air pressures. It is recommended that air pressure measures 90 psig at the tool with the trigger fully depressed and no load applied to the tool. Higher pressure (over 90 psig; 6.2 bar) raises performance beyond the rated capacity of the tool, which will shorten tool life and could cause injury. Always use clean, dry air. Dust, corrosive fumes and/or water in the air line will cause damage to the tool. Drain the water from air lines and compressor prior to running tool. Clean the air inlet filter screen weekly. The recommended hookup procedure can be viewed in the Figure 1. The air inlet used for connecting air supply has standard 1/4" NPT. Line pressure should be increased to compensate for unusually long air hoses (over 25 feet). Minimum hose diameter should be 3/8" I.D. and fittings should have the same inside dimensions and be tightly secured. Always turn off the air supply, drain hose of air pressure and detach tool from air supply before installing, removing or adjusting any part or ac- cessory on this tool, or before performing any maintenance on this tool. Ensure an accessible emergency shut off valve has been installed in the air supply line and make others aware of its location. LUBRICATION Lubricate the air motor daily with high quality air tool oil. If no air line oiler is used, run 1/2 oz. of oil through the tool. The oil can be squirted into the tool air inlet or into the hose at the nearest con nec tion to the air supply, then run the tool. The oil plug is only for adding multi-purpose grease after repair or maintenance of the impact mechanism. Overfilling will cause a re duc tion in the power of the tool. WARNING: After an air tool has been lubricated, oil will discharge through the exhaust port during the first few seconds of operation. The exhaust port must be covered with a towel before applying air pressure to prevent serious injury.
