* Important Safety Rules
I. Always wear safety goggles or glasses.
2. Always ensure machine is switched off before connecting to air supply.
3. Disconnect any machine from the air supply before changing blades or discs, and before servicing any type
of
machine.
4. Always keep your air tool clean and lubricated. Daily lubrication is essential to avoid internal corrosion and
possible failure.
5. Do not wear watches, rings bracelets or loose clothing when using air tools.
6. Using only light weight coil hoses from a tool to the wall or compressor coupling. Do not fit quick change
couplings onto the machine as vibration can cause the coupling to fail.
7. Do not overload the machine. Allow the tool to operate at its optimum speed for maximum efficiency.
8. Do not increase the air pressure above the manufacturers recommended level, as excessive overload can cause
the machine casing to split. Also this creates excessive wear on moving parts and possible failure.
9. In the interests of safety and possible damage to the machine/operator, always ensure that the machine has
stopped before putting it down after use.
10. Always ensure that the work piece is firmly secured leaving both hands free to control the machine.
11. Always ensure that the accessories such as blades, discs, sockets, etc. are rated/designed for use with the
machine. Also correctly and securely fastened before connecting the machine to the air supply.
12. When grinding, sanding or cutting always wear an appropriate face mask or respiratory equipment.

Air supply
1. Ensure wrench air valve (or trigger) is in the "off' position before connecting to the air supply.
2. You will require an air pressure of 90psi, and an 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 inthe 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 minimum hose diameter should be 1/4" I.D. and fittings must have the same inside
dimensions.
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_,?pen 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 wearprematurely.
• Use the proper lubricant in the air line lubricator. The lubricator should
be oflow air flow or changing air flow
type, and should be kept filled to the
c01/rect level. Use only recommended lubricants, specially made for
pneumatic applications. Substitutes may
!)arm the rubber compounds in the tools 0-rings and other rubber
parts. I
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. ·

* Maintenance
MvidQHUt4isconnect tool from air supply before changing accessories, servicing or performing
maintenance. Replace or repair damaged parts. Use genuineparts only. Non-authorisedparts may be dangerous
and will invalidate the warranty.
1. Lubricate the air tool daily with a few drops of air tool oil dripped into the air inlet
2. Clean the tool after use. DO NOT use worn, or damaged tooL
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.
b) Grit or gum deposits in the tool may also reduce performance. If your model has (Ill air strainer (located in the
area
of the air inlet), remove the strainer and clean it.
5. When not in J!Se, disconnect from air supply, clean tool and store in a safe, dry, childprooflocation.

* Trouble Shooting
The following form lists the common operating system with problem and solutions. Please read the form
carefully and follow it.
"'"WARNING:
f 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 0-rings or Cylinder,
lubricate with air tool oil before assembly.
PROBLEMS
POSSIBLE CAUSES REMEDIES
Tool runs at normal speed • ., Motor parts worn. • Lubricating clutch housing.
but loses under load • Cam clutch worn or sticking • Check for excess clutch oil. Clutch cases need
due to lack of lubricant. only be half full. Overfilling
can cause drag on high speed clutch parts, ie. a
typical oiled/lubricated wrench requires
l;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 • Motor parts jammedwith • Check air inlet filter for blockage.
