A. Features & Functions
* Durable twinhammer impact mechanism.Pressure-feed lubrication.
* Adjustablepower regulator.Variable speed.
* Sheer power and performance features to tackle tough jobs with ease and proven
durability.
B. Operating Instructions
1. Operation
The tool featuresan air regulator(at the topback of thetool) allowing youto vary the
amount of torqueexerted on thenut or boltyou are workingon. Setting 0 is the
lowest setting andSetting 5 is the highestsetting and providesthe biggest torque
and speed.
2. Loosening
- Step 1:Attach the correctsize socket tothe anvil.
- Step 2: Setthe compressor’s pressure regulator to 90PSI. Do not set the
compressor’s outlet regulator above 90PSI.
- Step 3: Connectthe tool tothe air compressor’s hose. If leakage is detected,
disconnect the airhose and fixit correct beforeuse.
- Step 4: Placethe socket overthe nut toloosen.
- Step 5: Gripthe tool firmly. Press theREVERSE Valve forward atthe top backof
the tool. Pressthe trigger tostart the tool.
(Caution: Make sure the nut orbolt can withstandthe impact wrench’s working torque.)
* Note:
- If the toolcannot loosen thenut, DO NOTraise the outletpressure of theair
compressor.
- If the tool’s air regulatoris set ina low setting,you may raisethe setting andtry
again. If thetool’s airregulator is alreadyset on 5 setting, do notcontinue
attempts to loosenthe nut withthe tool. Useother appropriate toolsand methods
Toloosen the nut.
- When the nutis removed, stopthe tool byreleasing the triggerand remove the
tool from thenut. Remove thenut from thesocket if needed.
3. Tightening
(The working torque of the impact wrench is 585 feet/lbs. Make sure that the nut or
bolt you areusing the toolto tighten canwithstand the ratedtorque.)
- Step 1:Tighten thenut as faras you canby hand.
- Step 2:Place the socketon the nut.Press the REVERSEValve backward at the top
back of thetool. Press thetrigger to startthe tool.
* Note:
- If the tool stalls while tightening, DO NOT raise the outlet pressure of the air
compressor above 90PSI.
- If the tool’s air regulator is seton a low setting, it may be raised andtry again. Ifthe
nut will not tighten at the maximum setting, do not continue attempts to tighten the
nut. Use otherappropriate tools andmethods to tightenthe nut.
- When the nut has been tightened, removethe tool andsocket. Do notover-tighten.
- If available, check the recommended torque specifications for the nut. You should
use a torquewrench to torquethe nut afterusing the impactwrench.
C. Air Supply (please refer to the diagram below)
1. Make sure that the air compressor being used for the air tool operation supplies the
correct output (CFM).
2. Turnthe throttle inthe off position when connectingthe tool tothe air supply.
3. Use normal90psi (or ranging from 6.0 to 8.0kg.) air pressure while running the tool.
High pressure and unclean air will shorten the tool’s life due to faster wear and also
may create ahazardous situation.
4. Drain the air tank daily. Water in the air line may enter the tool and damage the tool
mechanism at theoperation.
5. Clean the air inlet filter cartridge weekly. The recommended hook-up procedure can
be viewed inthe diagram below.
6. Line pressure should be increased accordingly to make up for extra long air hoses
(usually over 8 meters). The minimum hose diameter should be 1/4 I.D. and the
fittings should have the same inside dimensions. But usually a 3/8 I.D. air hose is
recommended for airsupply to getthe best functionof air tooloperation.
7. Use properhoses and fittings. We do not suggest connecting quick changecouplings
directly to the tool since they may cause failure due to vibration. Instead, add a
leader hose andconnect coupling betweenair supply andhose whip.
8. Keep hoses away from the heat, oil and sharp edges. Check hoses for wear before
