Residual risks
Even when the tool is used as prescribed it is not possible to eliminate all residual risk factors. The following
hazards may arise in connection with the tool’s construction and design:
1. Damage to lungs if an effective dust mask is not worn.
2. Damage to hearing if effective hearing protection is not worn.
3. Health defects resulting from vibration emission if the power
tool is being used over longer period of time or not adequately
managed and properly maintained.

Important Safety Rules
1. 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.
IMPORTANT:
Upon receipt of the product, read and follow all safety
rules, operating instructions before first use it. And retain
this manual for future reference.

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.
Operating Instruction
Description
Built-in regulator for speed control, low vibration, lightweight and ergonomic design, Rear exhaust, 10000 RPM will be
well for most of auto finishing applications for producing fine finishes.
Air supply
1. You will require an air pressure of 90psi, and an air flow according to specification.
2. 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
and/or personal injury.
3. Drain the air tank daily. Water in the air line will damage the wrench.
4. Clean air inlet filter weekly. Recommended hook-up procedure is shown in fig 4.
5. Line pressure should be increased to compensate for unusually long air hoses (over 8 metres). The minimum hose
diameter should be 3/8” I.D. and fittings must have the same inside dimensions.
6. 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. As a standard practice,drain walter from the air compressor tank and air lines prior to use each day(reference your
compressor operators manual for detailed instructions).
2. Install a 1/4” male connector(not included)into the air inlet port on the tool.
3.Turn on the air compressor and allow it to build up pressure.
4. To assemble the backing disks and sandpaper.

5. Adjust the air compressor’s regulator or the supply line regulator to 90PSI.
6.Connect the tool to the air hose quick coupler.
7.Adjust the regulator control knob to the desired variable speed.
8.Squeeze trigger gently. Start the sander off the work. Set it down on the outer portion of the sandpaper with tool. held at
a slight angle to the work surface. Move the sander slowly back and forth in wide overlapping areas. Let the sander do the
work surface. Do not put additional pressure on the sander. This slows down the speed of the pad, reducing sanding
efficiency and puts additional burden on the air tool motor.
9.When finishing sanding, lift sander off the work before releasing the trigger.
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 and will invalidate the
warranty.
1. Lubricate the air sander 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 an air strainer (located in the area of
the air inlet), remove the strainer and clean it.
5. When not in use, disconnect from air supply, clean tool 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.
