GENERAL SAFETY RULES 3 WARNING! ● Improper operation or maintenance of this tool could result in personal injury and/or property damage. Read and understand all warnings and operation instructions before using this tool. ● When using this tool, these basic safety precautions should always be followed to reduce the risk of personal injury and/or property damage. Workplace conditons 1. Always work in a clean, dry, well-ventilated area free of combustible materials.
14. Never use the tool if it is defective, damaged, or operating abnormally. 15. Check for misalignment or binding of moving parts, breakage of parts and any other condition that affects the tool operation. If damaged, have the tool serviced before using. 16. Keep working parts of the tool away from hands and body. 17. Do not carry the tool by the air hose. 18. Do not apply excessive force of any kind to the tool. Let the tool perform the work at the rate as it was designed. 19.
Air ratchet wrench safety instructions 5 1. Always use the ratchet wrench in the manner and for the functions described in this manual. 2. Always ensure the wrench is not moving and disconnected from the air supply when changing sockets etc. Only use impact sockets. Do not use standard sockets. 3.
8. A long air hose (usually over 25 feet) may cause up to 15psi drop in pressure, so you need to set the output pressure of the air compressor higher to maintain the required working pressure at the tool. 9. Use proper hoses and fittings. We do not suggest connecting quick change couplings directly to the tool since they may cause failure due to tool vibration at operation. Instead, add a lead hose and connect coupling between air supply and hose whip. 10. Check hoses for wear before each use.

ASSEMBLY 1/2" AIR IMPACT WRENCH 9 1 1. Remove the air inlet protective cap from the air inlet (C1). (See Figure 1) C1 2. Mount a male plug by hand into the air inlet (C1). (See Figure 2) 2 NOTE: Use thread sealant tape on the male plug and tighten it with a wrench for airtight connection. Do not overtighten. 3. Place 2 - 3 drops of air tool oil into the male plug before each use.
4. Choose the correct impact socket (S) as needed and mount it onto the anvil (F1). (See Figure 4) WARNING! Only use impact sockets that have a RPM and Torque rating equal to or greater than the tool itself. 5. If necessary, use the 1/2" extension bar (V) and then mount impact socket onto the bar. (See Figure 5) 10 4 S F1 5 V S 6. Connect air supply hose to the male plug. (See Figure 6) 6 7. Set the working pressure at 90psi/6.3bar for best tool performance.
3/8" AIR RATCHET WRENCH 1. Remove the air inlet protective cap from the air inlet (E2). (See Figure 7) 11 7 E2 2. Mount the male plug by hand into the air inlet (E2). (See Figure 8) 8 NOTE: Use thread sealant tape on the male plug and tighten it with a wrench for airtight connection. Do not overtighten. 3. Place 2 - 3 drops of air tool oil into the male plug before each use.
4. Choose the correct impact socket (S) as needed and mount it onto the anvil (H2). (See Figure 10) WARNING! Only use impact sockets that have a RPM and Torque rating equal to or greater than the tool itself. 5. Connect air supply hose to the male plug. (See Figure 11) 12 10 S H2 11 6. Set the working pressure at 90psi/6.3bar for best tool performance. NOTE: Working pressure refers to the air line pressure set to tool when tool is under working conditions.
OPERATION 1/2" AIR IMPACT WRENCH 1. How to install/tighten threaded fasteners. Push the Forward/Reverse rotation control (B1) forward and have the arrow on the Forward/ Reverse rotation control (B1) pointing at either of the three dots on the back housing as shown. Press the trigger (D1). The tool anvil (F1) runs clockwise. (See Figure 12) 2. How to remove/loosen threaded fasteners.
NOTE: This tool also features a grease cap (E) on the protector cover. Remove the screw in the grease cap (E1) with a hex key (not provided). Use a grease gun (not provided) and insert the gun nozzle into the grease cap (E1). Several drops of grease are recommended for lubricating the internal hammer assembly. This will help the hammer assembly to work in good condition and extend tool life. Lubricate the hammer assembly once every working day. (See Figure 15) 3/8" AIR RATCHET WRENCH 1.
NOTE: This tool features a power regulator valve. Rotate the air regulator (F2) until desired output is achieved. The settings 1, 2, 3, 4 are only for reference and do not denote a specific power output. “Setting 1” (one-line symbol) is the least amount of power while “Setting 4” (four-line symbol) is the most amount of power. Rotate the air regulator (F2) until the desired setting is lined up with the small steel ball (D2) on air inlet (E2).
TROUBLESHOOTING PROBLEM Tool runs slowly or will not operate POSSIBLE CAUSE 1. Grit or gum in tool. CORRECTIVE ACTION 1. Flush the tool with air-tool oil or gum solvent. 2. Lubricate the tool. 2. No oil in tool. 3. a. Adjust the regulator on the tool to 3. Low air pressure. maximum setting. b. Adjust the compressor regulator to tool maximum of 90 PSI/6.3 BAR. 4. Tighten and seal hose fittings if leaks are 4. Air hose leaks. found. Use sealing tape. 5. a. Be sure the hose is the proper size. 5.
