that is left attached to a rotating part of the tool mayresult in personalinjury.
5. Do not overreach. Keep proper footingand balance at all times. Properfooting
and balance enables better controlof the toolin unexpected situations.
6. Use safety equipment. Always wear ANSI-approved safetyglasses underneath a
full face shield, and hearing protection.
Use and Care
1. Use clamps or other practicalways to secure and support the work piece to a stable
platform. Holding the work byhand is unstable and may lead to loss ofcontrol. Only
work on a workpiece that is properly secured.
2. Do not force the tool. Use the correct tool for your application.The correct toolwill
do the job better and safer at the rate for which it is designed.
3. Do not use the power tool ifthe trigger does not turn it on or off. Any toolthat cannot
be controlled with the Triggeris dangerous and must be replaced.
4. Disconnect the air hose from the tool before making anyadjustments, changing
accessories, or storingthe tool. Such preventive safety measures reduce the risk
of starting the tool accidentally.
5. Store idle tools out ofreach of children and other untrained persons. Tools are
dangerous in the hands of untrained users.
6. Maintain tools with care. Do not use a damaged tool. Tag damaged tools "Do not use"
until repaired.
7. Check for misalignment or binding ofmoving parts, breakages of parts, damaged air
hose (not included), and any other condition that may affect the tool's operation. If
damaged, have the tool serviced before using. Many accidents are caused by poorly
maintained tools.
8. Use onlyaccessories that are recommended by the manufacturer for your model.
Accessories that may be suitable for one tool may become hazardous when used on
another tool.

Loosening
1.Attach thecorrect size socketto the anvil.
2.Set thecompressor's pressure regulatorto 90 PSI. Do not setthe compressor's
outlet regulator above90PSI.
3.Connect thetool to theair compressor's hose. If leakage isdetected, disconnect
the air hoseand fix itcorrect before use.
4.Place thesocket over thenut to loosen.
5.Grip thetool firmly. Press theREVERSE valve infrom the areaabove the trigger
so that theREVERSE valve protrudesout the backof the housing. Press the trigger
to start thetool.
Caution:

NOTE:
ØIf the toolcannot loosen thenut, DO NOTraise the outletpressure of theair
compressor.
ØWhen the nutis moved, stopthe tool byreleasing the triggerand remove thetool
from the nut. Remove the nutfrom the socketif needed.
Tightening
The working torque of the impact wrench is 230 ft.-lbs. Make sure that the
nut or bolt you are using the tool to tighten can withstand the rated torque.
1.Tighten the nut as far as you can by hand.
2.Place the socket on the nut. Press the REVERSE valve forward so it protrudes
