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.
