SAVE THESE INSTRUCTIONS FOR FUTURE USE
INSTALLATION
AIR SUPPLY
The recommended hook-up is shown in
Figure A.
Pneumatic tools operate on a wide range of air pressures. For maximum efficiency and longer tool life, the pressure of the air supplied to these tools MUST not exceed the rated PSI at the tool when the tool is running. Using a higher than rated pressure will cause faster wear and drastically shorten the tool’s life. A higher air pressure can also cause an unsafe condition and explo­sion. The inside diameter of the hose 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 1/4” NPT thread. The use of air line lubricators and air line filters is recommended to prevent water in the line that can damage the tool. Drain the air tank daily. Clean the air inlet filter screen on at least a weekly schedule to remove accumulated dirt or other matter that can restrict air flow. The tool’s air inlet used for connecting an air supply has standard 1/4” NPT American thread.
SAFETY RULES FOR PNEUMATIC TOOLS
1) Inspect the air hose for cracks or other problems. Replace the hose if worn.
2) Never point an air hose at another person.
3) Disconnect the tool when not in use, or before performing service or changing accessories.
4) Use proper hoses and fittings. Never use quick change couplings attached to the tool. Instead, add a hose and coupling between the tool and the air supply.

PREPARATION FOR USE
PROPER USE OF THE TOOL
Your new 1/2” Drive Impact Wrench is designed for driving, tightening and loosening threaded fasteners, usually nuts and bolts, when tted with a suitable impact socket.
Always use impact-rated extension bars,
universal joints and socket adapters between the square output drive of the impact wrench and the female square drive of the socket. Do not use the tool for any other purpose than that specied without consulting the manufacturer or the manufacturer’s authorized supplier. To do so may be dangerous.
Never use the impact wrench as a hammer to dislodge or straighten cross threaded fasteners. Never attempt to modify the tool for other uses.
WORK STATIONS
Your impact wrench should only be used as a hand operated tool. It is always recommended that the tool is used when standing with solid footing. It can be used in other positions but before any such use, the operator must be in a secure position having a rm grip and footing and be aware that when loosening fasteners the tool can move quite quickly away from the fastener being undone. An allowance must
always be made for this rearward movement so as to avoid the possibility of hand/arm/body entrapment.

PUTTING INTO SERVICE
AIR SUPPLY
Use a clean lubricated air supply that will give a measured air pressure at the tool of
90 psi/6.2 bar when the tool is running with the trigger fully depressed. Use recommended hose size. It is recommended that the tool is connected to the air supply as shown
in
figure A
on page 7 . Do not connect the tool to the air line system without incorporating an easy to reach and operate air shut off valve. The air supply should be lubricated. It is strongly recommended that an air lter, regulator,
lubricator (FRL)
is used as shown in
figure A
on page 7 as this will supply clean, lubricated air at the correct pressure to the tool. Details of such equipment can be obtained from your supplier. If such equipment is not used then the tool should be lubricated by shutting off the air supply to the tool and then depressurizing the line by pressing the trigger on the tool. Disconnect the air line and pour into the air inlet 1 teaspoon (5cc.) of a suitable pneumatic motor lubricating oil, preferably incorporating a rust inhibitor. Reconnect tool to air supply and run tool slowly for a few seconds to allow air to circulate the oil.
Lubricate tool daily if used frequently, or when it starts to slow or lose power.
USING AN IMPACT WRENCH
1) Read all instructions before using this tool. All operators must be fully trained in its use and aware of these safety rules.
2) Do not exceed the maximum working air pressure of 90 psi/6.2 bar.
3) Use personal safety equipment.
4) Use only compressed air at the recommended conditions.
5) If the tool appears to malfunction, remove from use immediately and arrange for service and repair.
6) If the tool is used with a balancer or other support device, ensure that it is xed securely.
7) Always keep hands away from the working attachment tted to the tool.
8) The tool is not electrically insulated. Never use the tool if there is any chance of it coming into contact with live electricity.
9) When using the tool, always adopt a firm footing and/or position and grip the tool firmly to counteract any forces or reaction forces that may be generated while using the tool.
10) Use only correct spare parts. Do not improvise or make temporary repairs.
11) Do not lock, tape, wire, etc. the on/off trigger in the run position. The trigger must always be free to return to the “off” position when it is released.
12) Always shut off the air supply to the tool and depress the trigger to release air from the feed hose before tting, adjusting or removing the working attachment.
13) Check hoses and fittings regularly for wear. Replace if necessary. Do not carry the tool by its hose. Ensure the hand is removed from the on/off trigger when carrying the tool with the air supply connected.
14) Take care against entanglement of moving tool parts with clothing, ties, hair, cleaning rags, etc. This will cause the body to be drawn towards the tool and can be very dangerous.
15) It is expected that users will adopt safe working practices and observe all relevant legal requirements when installing, using or maintaining the tool.
16) Only install the tool when an easily accessible and easily operable on/off switch is incorporated in the air supply.
17) Take care that the tool exhaust air does not cause problems or blow onto another person.
18) Never lay a tool down unless the working attachment has stopped moving.
19) Always ensure that the forward/reverse switch is in the desired position before starting the tool.
20) Do not use sockets with excessive wear to the input or output drives. Periodically check the squae drive on the impact wrench. Make surer the socket, extension bar, or other attachment is securely tted before operating tool.
21) When loosening fasteners rst ensure that there is sufcient clearance behind the tool to avoid hand entrapment. The tool will move away from the threaded joint as the nut/bolt is loosened and rides up the thread, moving the tool with it.
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 lled.
• 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 t 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.
