Noise
• The operator must wear the ear protector when the noise level at this position exceeds
85dB(A). It is recommended that the operator wears the ear protector even if the noise
levels less than 85dB(A).
Vibration
• The operator is exposed to get the risk caused by vibrations. Frequent and prolonged
exposure to high intensive vibrations can cause disorders, especially to hands and
arms. Disorders caused by vibrations depend on many factors such as type of tool, type
of work, individual operator, and his physical conditions, working conditions, working
period, design of tool, temperature, etc. The operator must use the tool in accordance
with the total daily usage of ISO5349.
Mounting and Dismounting Abrasive Product
• When mounting and dismounting the abrasive product, make sure that the air line is not
connected to the tool or that the air line is shut off.
• Make sure that the dimensions of the abrasive product are compatible to the tool and
that the abrasive product fits the spindle of the tool.
Suggested gripping and over-hanging length
• The minimum gripping length of insert tool should be no less than 10mm.

Checking Abrasive Product
y
Use only the appointed abrasive products. Do not use worn out product.
y
Handle and store the abrasive product with care in accordance to its manufacturer’s
instructions.
y
In an extremely high or low temperature, allows the tool and the abrasive products a
sufficient slow revolution.
y
After mounting the abrasive product, run the tool at no load for about 3 minutes in a safe
place such as under a workbench or under an isolated place. Stop the operation
immediately when you feel an unusual vibration, hear unusual sound, notice unusual
change in speed and/or find any other irregularity.
Correct Working with Tool
y
Always consult the manufacturer before attempting to install and use the tool if there
should be any doubt about safety and appropriate use of tool or the abrasive product or
accessory.
y
Do not modify the tool without permission or agreement from the manufacturer.
y
Never use or continue to use the tool when you feel unusual vibration, hear unusual sound,
notice unusual changes in speed and find any other irregularities.
y
The tool should be used according to its capacity and only for its own purpose.
y
Do no touch the abrasive product mounted on the tool during operation.
y
Be aware of long hair, loose clothing, ties, etc. drawing in the tool.
y
Make sure that sparks resulting from use are directed so that they do not hit persons,
flammables substances, etc.
y
Make sure that the workpiece is properly supported or fastened so as to avoid kick back.
y
Be aware that the tool will keep running-on for a while even after turning off. Do not touch
the abrasive tool until it came to completely stop. It is very dangerous to touch the
abrasive product soon after stopping operation.
y
Never carry the tool by the hose or yank it to disconnect from power supply.
y
Do not use the air hose for supporting, lifting or lowering the tool.
y
Make sure that other people in the work area are at the safe distance.
y
Do not abandon the tool during operation.
y
Do not start the operation of the tool when it is laid down.
Keeping Tool After Use
The tool must be kept in a clean, dry place, so that it can be used properly easy and safely.
The storage of tools should be in a humidity controlled room. Avoid large temperature
fluctuations room.
Maintenance and Repairs
y
The tool must be properly maintained and tested by competent and trained personnel. At
any sign of malfunction or unusual behavior, the tool should be taken out of service for
examination and repair.
y
It is recommended to dismantle the tool for overhauling and cleaning periodically after 500
hours of operation or once every six months.
y
When giving maintenance or repairs, make sure to disconnect the tool from the air line or
to shut off the air supply.
y
Before clearing the tool for use, make sure that all parts have been correctly assembled
with all fasteners tightened.
y
Check the speed or rpm of the tool without the abrasive product on the spindle after each
maintenance or repairing.
Disposal of Tool
The tool is made of steel, casting iron, brass, bronze casting, aluminum alloy, rubber and
plastic components or using some of those materials. When disposing of the tool, be sure not
to cause pollution to human beings and environment.
