B. Rules for Long Lasting and Performance Utilization
Air Tools and the 3-in-1 units, Filter/Regulator and Lubricator
1. For the air tool to remain in the best performance and prolong its life, it is necessary
and important to equip it with the 3-in-1 unit (Filter/Regulator & Lubricator).
If the Lubricator is not being used, it is recommended to put a few drops of
oil per every 2 to 3 hours of operation.
2. Before starting, use few drop of turbine oil at the tip of the air hose for lubrication.
3. Set the pressure controller (regulator) at 90psi, which is recommended air
pressure for all air tools. Higher pressure is not necessary and will shorten the tools’
life or cause damage to the tools.
4. Turn on the tool and let it run freely (at no load) for few seconds before operation or
before working on the workpiece.
5. Keep the compressed air in dry condition at all times to prevent rust that destroys the
tools. Avoid moistness or water that gets inside the hand-piece by checking the filter
frequently. The air filter on the 3-in-1 unit is used for drying out water. Always check
that the air filter tube does not contain over 80% water. It is advisable that the filter is
drained daily.
6. Make sure that the lubricator or oiler unit is lubricated or contains lubrication oil at all
times. Use only a good grade of light oil, it is important not to use thick and greasy oil.
7. Set the oil controller at 2 drops per minute for lubrication. During the weekend or
a long period of inactivity, increase to 4 or 5 drops per minute, leave the tool running
free for 30 to 60 seconds before turning off the tool.
8. Keep the unit away from fire, corrosion, moisture.
Operation Conditions; Start & Stop Device
• The on/off switch is ring throttle action, which is located in the proximity of the hand-
grip; turn the throttle counter clockwise to open and turn clockwise to close it.
• Before connecting to or turning on the air supply, make sure that the throttle is in the
off position.
C. Safety Instructions and Warning
Safety is a primary consideration when using the air tools. The tool should be used in
the right way with a good understanding of how to use the tool safely. Read and fully
understand all the instructions before using this tool.
• The tool is designed to be used with the abrasive product for fine polishing. Do not
use this tool for any other purpose.
• Do not burst into full speed operation, which might cause danger from over speed.
• Check the air pressure level before starting the operation. Pressure less than 90psi
will reduce output and speed, while higher pressure will lead to premature wear and
excessive speed. Excessive pressure is dangerous and shortens tool life.
• Observe accurate mounting of insert tools.
• If noise levels exceed 85dB(A) at the workstation, the operator must use ear plugs
and/or ear mufflers.
• Operator is exposed to the risk caused by vibration. Frequent and prolonged
exposure to high intensive vibration can cause disorders, especially to hands and
arms. Disorders caused by vibration depend on many factors such as types of tool,
type of work, individual operator, and his/her physical conditions, working conditions,
working period, temperature, etc. The operator must use the tool in accordance with
the tool daily usage of ISO5349.
• The operator shall wear necessary protective approved equipment such as eye
protector, goggles, or face shield at all times during operation. Additional protection
devices should be used where necessary.
• The stopping time or run-down time can be of several seconds, the operator shall pay
attention to the risk of drawing in long hair, loose cloth; risk of a whipping compressed
air hose.
• The working area should be well ventilated to avoid possible contaminants in the
compressed air exhaust.
• Seek medical advice immediately if any lubricant should contaminate the eyes or be
accidentally ingested.
Protection Devices
• Always wear necessary protective approved equipment such as eye protector, ear
protector, face shield, safety apron, helmet, gloves and any necessary protective
clothing.
Air Hose and Fittings
• Use only the correct, clean air hose and fitting and always check that they are in
good condition and properly installed. Do not use damaged, frayed or deteriorated
hose and fittings, which can cause injury.
• Always keep the hose away from heat sources and sunlight and store it properly after
using and check it before use.
• The air hose may come off and whip if it is not correctly used or the fittings are not
properly installed.
• Avoid using a long hose, short length of hose should be chosen.
Lubrication
• Air line lubricator should be used. Do not burst into full speed operation. Lithium
system grease is recommended for lubrication of bearings, can and clutch part, gears
and gear cases. Lubricate them when giving maintenance or periodical inspection.
• Seek medical advice immediately if any lubricant should contaminate the eyes or be
accidentally ingested.
