OPERATIONS
1. Precision adjustment has been made around case, gear and rotating section.
2. Smooth change of valve reverse (right/left) button turn direction can be done.
3. Push valve reverse button makes instantly change direction of air motor rotation.
4. Lever-to-Start system eliminates troublesome to press push-to-Start.
5. Easy adjusting fastening torque by tightening or loosening nut torque indication.
Tighten to the right: increase torque. Loosen to the left: decrease torque
6.Air motor will automatically stop when the load reaches at the pre-set torque
AIR SUPPLY
1. Air tools are adversely affected by moisture. Since air from compressor contains much moisture and dust,
it is desirable to provide a filter and lubricator in the pipeline to remove such undesirable elements. Also
take the drain out from air tank every day.
2. When using brand-new air hose or air pipe. Blow and clean the inside of air hose or pipe before
installation.
3. Keep inside of air hose or air pipe clean to prevent airdrop problem caused by the lots of drain and dust
accumulated and possibly make the inside diameter smaller in the long use.
4. When disconnect air hose from air tool while in the operation do not drop air hose end to the floor as dust
or other element may come into air hose.
5. Use air regulator to keep stable air pressure at 5.5kg/cm2-6.0kg/cm2at the toll. It is important to get
proper air pressure at the toll.
6. After lubrication, oil will discharged the exhaust upon operation. Flush motor for a few seconds.
LUBRICATION
1.Lubrication is indispensable to air tolls. The most ideal maintenance is to install one lubricator
to a toll for automatic oil feed, but if it is not available, manual lubrication twice every
day is recommended for longer life and keeping the efficient function of mechanism.
2.For manual lubrication, disconnect air hose from bushing air inlet and full up spindle
oil (#40-#60) into the air feed in take and push the bit.

General preparation and connection:
1. When using brand-new air hose or air pipe. Blow and clean the inside of air hose or pipe before installation.
2. Keep inside of air hose or air pipe clean to prevent airdrop problem caused by the lots of drain and dust accumulated and possibly make
the inside diameter smaller in the long use.
3. Before connecting the air hose, apply 4 to 5 drops of SAE#10-20 spindle oil at the air inlet. Also, every 3 to 4 hours of operation, oiling is
necessary. Twist Teflon thread tape to ensure a proper seal air inlet. Then tighten the air coupler into air tool.
4. The supplied compressed air must be clean and dry, with the appropriate oil mist. Use an air treatment unit; filter, regulator and
lubricator.
5. Please refer Fig.1 illustration shows the correct mode of connection to the air supply system which will increase the efficiency and useful
life of the tool.
6. The quick connect coupling and hose must have sufficient air flow capacity. We recommend an air hose with a diameter of 10mm (3/8”).
7. To ensure a good performance. The operation pressure at the compressed air inlet should not exceed 6.2bar (90psi) (unless indicated
otherwise). Higher operating pressures may cause damaged or excessive wear. Operating pressures below 5.3bar may cause pressure
or power loss.
Risk of injury
1. Compressed air can inflict serious injuries. Therefore never point the air hose at another person or yourself.
2. Shut –off the air supply and disconnect the tool in case:
➢You want to change or replace accessories.
➢You want to clean, repair or maintain the tool.
➢The tool is not going to use for some times.
3. Check compressed air hose before use. If it is damaged, broken, torn, or deformed, the hose is not to be connected to the tool.
4. Always check the pneumatic couplings before using the tool. If they show signs of damage, fracture, cracking or excessive corrosion,
the respective tool or the air hose is not to be used.
5. Use only qualified adapters and connectors, In case of wear they are to be replaced immediately.
6. Only use air pipes that are fit for the use at maximum pressure.
Maintenance instruction:
1. Dry the filter (fig1) and the air inlet of the tool.
2. Lubricate the quick connect coupling to prevent blocking.
3. Air tool require lubrication throughout the life of the tool. The air motor and bearing uses compressed air to start the tool. The
moisture in compressed air will rust the air motor; you must lubricate the motor daily.
4. Avoid storing the tool in a location subject to high humidity. If the tool is left as it is used, the residual moisture inside the tool
can cause rust.
5. Before storage, lubricate tool and run it for a few seconds.
6. Regular inspection of spindles, threads, and clamping devices in respect of wear and tolerances for location of abrasive
products.
7. If the tool is too seriously damage to be used anymore, recycle raw material instead of disposing as waste. The machine,
accessories and packaging should be sorted for environmental-friendly recycling. Check with your local authority or retailer
for recycling advice.
