Using an Impact Wrench Continued
10)Use only genuine Dewalt spare parts or parts which perform equivalently. Do not make temporary or permanent repairs with unauthorized parts.
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 fitting, 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)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 square drive on the impact wrench. Make surer the socket, extension bar, or other attachment is securely fitted before operating tool.
21)When loosening fasteners first ensure that there is sufficient 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.
WARNING: Risk of unsafe operation. Firmly grasp air hose with hand when installing or disconnenting to prevent hose whip. 
WARNING: 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. 2)
•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 10 for diagram.
•Depress the trigger to start operating the tool.
SHUT-DOWN (FIG. 1, PG. 2)
•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.
