Additional safety instructions for pneumatic power tools
always shut off air supply, drain hose of air pressure and disconnect tool from air supply when not in use, before
changing accessories or when making repairs;
t use quick-disconnect couplings at tool inlet for impact and air-hydraulic impulse wrenches. Use hardened steel
(or material with comparable shock resistance) threaded hose fittings.

cables shall be used to safeguard against possible hose-to-tool and hose-and-hose connection failure.
-control and continuous-rotation tools, the air pressure has a safety critical effect on performance. Therefore,
requirements for length and diameter of the hose shall be specified.
Air supply
1. Ensure wrench air valve (or trigger) is in the “off” position before connecting to the air supply.
2. It will require air pressure of 90psi, and air flow according to specification.
3. WARNING! Ensure the air supply is clean and does not exceed 90psi while operating the wrench. Too high an
air pressure and unclean air will shorten the product life due to excessive wear, and may be dangerous causing
damage or personal injury.
4. Drain the air tank daily. Water in the air line will damage the wrench.
5. Clean air inlet filter weekly.
6. Line pressure should be increased to compensate for unusually long air hoses (over 8 metres). The hose diameter
should be 5/8” I.D.
7. Keep hose away from heat, oil and sharp edges. Check hose for wear, and make certain that all connections are
secure.

Lubrication
An automatic in-line filter-regulator-lubricator is recommended (Fig4) as it increases tool life and keeps the tool in
sustained operation. The in-line lubricator should be regularly checked and filled with air tool oil.
Proper adjustment of the in-line lubricator is performed by placing a sheet of paper next to the exhaust ports and
holding the throttle open approximately 30 seconds. The lubricator is properly set when a light stain of oil collects on
the paper. Excessive amounts of oil should be avoided.
In the event that it becomes necessary to store the tool for an extended period of time (overnight, weekend, etc.), it
should receive a generous amount of lubrication at that time. The tool should be run for approximately 30 seconds to
ensure oil has been evenly distributed throughout the tool. The tool should be stored in a clean and dry environment.
It is most important that the tool be properly lubricated by keeping the air line lubricator filled and correctly
adjusted. Without proper lubrication the tool will not work properly and parts will wear prematurely.
Use the proper lubricant in the air line lubricator. The lubricator should be of low air flow or changing air flow
type, and should be kept filled to the correct level. Use only recommended lubricants, specially made for
pneumatic applications. Substitutes may harm the rubber compounds in the tools, O-rings and other rubber parts.
IMPORTANT!!!
If a filter/regulator/lubricator is not installed on the air system, air operated tools should be lubricated at least once a
day or after 2 hours work with 2 to 6 drops of oil, depending on the work environment, directly through the male
fitting in the tool housing.
Loading and operation
WARNING: Ensure you read, understand and apply safety instructions before use.
1. Only use impact sockets which are specifically designed for use with impact wrench.
2. Connect the wrench to the air hose .
3. Place the socket over the subject nut and depress the trigger to operate the wrench.
4. To change direction push the button at the top of the handle. Direction of .R. for reverse and “L” for forward
5. The flow of air may be regulated by adjusting flow valve at the base of the handle.
6. Ensure the air supply is clean and does not exceed 90psi while operating the wrench. Too high an air pressure and
unclean air will shorten the product life due to excessive wear, and may be dangerous causing damage or personal
injury.
7. Make children away from the tools and workplaces.
DO NOT use any additional force upon the wrench in order to remove a nut.
DO NOT allow wrench to free run for an extended period of time as this will shorten its life.

※Maintenance
WARNING: Disconnect wrench from air supply before changing accessories, servicing or performing
maintenance. Replace or repair damaged parts. Use genuine parts only. Non-authorised parts may be dangerous.
1. Lubricate the air wrench daily with a few drops of air tool oil dripped into the air inlet
2 DO NOT use worn, or damaged sockets.
3. Loss of power or erratic action may be due to the following:
a) Excessive drain on the air line. Moisture or restriction in the air pipe. Incorrect size or type of hose
connectors. To remedy check the air supply and follow instructions.
b) Grit or gum deposits in the wrench may also reduce performance. If your model has an air strainer (located
in the area of the air inlet), remove the strainer and clean it.
4. When not in use, disconnect from air supply, clean wrench and store in a safe, dry, childproof location.
※Trouble Shooting
The following form lists the common operating system with problem and solutions. Please read the form
carefully and follow it.
WARNING:If any of the following symptoms appears during your operating, stop using the tool immediately,
or serious personal injury could result. Only a qualified persons or an authorized service center can perform repairs or
replacement of tool.
Disconnect tool from air supply before attempting repair or adjustment. When replacing O-rings or Cylinder,
lubricate with air tool oil before assembly.
PROBLEMS
POSSIBLE CAUSES
REMEDIES
Tool runs at normal speed
but loses under load
Motor parts worn.
■Cam clutch worn or sticking
due to lack of lubricant.
■Lubricating clutch housing.
■ Check for excess clutch oil. Clutch cases need
only be half full. Overfilling
can cause drag on high speed clutch parts, ie. a
typical oiled/lubricated wrench requires 1⁄2
ounce of oil.
GREASE LUBRICATED:NOTE: Heat
usually indicates insufficient grease in chamber.
Severe operating conditions may require more
frequent lubrication.
Tool runs slowly. Air flows
slightly from exhaust
Motor parts jammed with dirt
particles
■Power regulator in closed
position
■Air flow blocked by dirt.
■Check air inlet filter for blockage.
Pour air tool lubricating oil into air inlet as
per instructions.
■Operate tool in short bursts quickly reversing
rotation back and forth where applicable.
Repeat above as needed.
Tools will not run. Air flows
freely from exhaust
■One or more motor vanes
stuck due to material build up.
■ Pour air tool lubricating tool into air inlet.
■Operate tool in short bursts of forward and/or
reverse rotation where applicable.
■ Tap motor housing gently with plastic mallet.
■ Disconnect supply. Free motor by rotating
drive shank manually where applicable
Tool will not shut off
■„O‟ rings throttle valve
dislodged from seat inlet valve.
■Replace „O‟ ring.
Note: Repairs should be carried out by a qualified person.
