PRE-START CHECKLIST
• Drain water from air compressor tank and condensation from air lines. (Please refer to air compressor’s
operation manual.)
• Lubricate the tool. (Please refer to the “Maintenance” section in the manual.)
• Select the necessary impact sockets. The sockets have to match with the size of the drive on the air
impact wrench.
• Connect air impact wrench to air source with the hose of recommended size.
Risk of unsafe operation. Firmly grasp air hose with hand when installing or
disconnenting to prevent hose whip.
Risk of bursting. Too much air pressure causes a hazardous risk of bursting. Check the
manufacturer’s maximum pressure rating for air tools and accessories. The regulator
output pressure must never exceed the maximum pressure rating.
OPERATING PROCEDURES
START-UP (FIG. 1, PG.3)
• Turn on the air compressor and allow the air tank to be filled.
• Set the air compressor regulator to 90 PSI. This air tool operates at a maximum of 90 PSI air pressure.
• Adjust power dial (if it is available) to desired torque.
• Adjust tool either in forward or reverse position. See Features on page 8 for diagram.
• Depress the trigger to start operating the tool.
SHUT-DOWN (FIG. 1, PG. 3)
• Release the trigger in order to stop the tool.
• When changing sockets, always disconnect air supply to avoid injury.
• When job is completed, turn off the air compressor and store the air tool after lubrication.
OPERATING INSTRUCTIONS
• Securely fit the socket or attachment to the impact wrench.
• Ensure that the forward/reverse switch is in the correct position for tightening or loosening the fastener.
• The nut/bolt can then run down the thread using the power drive of the tool. For loosening a joint the
tool can be used in the reverse sequence.
MAINTENANCE
LUBRICATION
Air tools require lubrication throughout the lifetime of the tools. The air motor and bearing uses
compressed air to power the tool. The compressed air contains moisture that will rust the air motor and
other parts in side of the tools, therefore lubrication is required daily. Failure to lubricate the air tool
properly will dramatically shorten the life of the tool and will void the warranty
This air tool requires lubrication BEFORE initial use, also before and after each additional
use.
TO LUBRICATE THE AIR TOOL MANUALLY:
1. Remove any attachment on the drive of air tools, such as: sockets, chisels and etc.
2. Disconnect the tool from the air supply source, place the air inlet face up.
3. Depress the trigger and place about 1 teaspoon (5cc.) of air tool oil into the air inlet. (Depressing the
trigger will help circulate oil in the motor.)
NOTE:Use SAE #10 weight oil if air tool oil is not available.
4. Connect the tool to an air source, cover the exhaust end with a towel and run for about 20 to 30
seconds.
Keep out of the reach of children. If taken internally, do not induce vomiting, call a doctor immediately.
