MAINTENANCE INSTRUCTION:
1.) LUBRICATION:
Before connection of the hose, apply 4 to 5 drops of a
good quality air tool oil at the air inlet. After 3 to 4 hours
of operation, oiling may be necessary again.
2.) TIGHTNESS OF PARTS:
Regularly check whether all connection parts are
fastened securely. Follow this procedure daily
before beginning work.
3.) STORAGE:
Avoid storing the tool in a location subject to high
humidity. If the tool is left unused, the residual moisture
inside the tool can cause rust. Before storing and after
operation, oil the tool at the air inlet with a good quality
air tool oil and run it for a short period.
4.) DISPOSAL:
Follow national legislation of waste disposal.
5.) ORDERING SERVICE PART:
For further operational and handling information or
for replacement of parts and components, contact the
sales agent from where you purchased the tool, or the
service division of our company, phone number
800-221-9705.
* When ordering parts and components, give each part
number, name, and quantities.
Users of this tool should review the chemical composition of
the work surface and any products used in conjunction with
this tool for any such chemicals prior to engaging in any
activity that creates dust and/or microscopic particles.
Users should obtain the Material Safety Data Sheets for all
identified chemicals, either from the manufacturer or their
employer, and proceed to study, understand, and follow all
instructions and warnings for exposure to such chemicals.
Some examples of these chemicals are: lead from lead
based paints; crystalline silica from bricks, cement and other
masonry products; and arsenic and chromium from chemically
treated lumber. A listing of the chemicals can be obtained at
www.oehha.ca.gov under Propoisition 65.
In order to reduce their exposure to such chemicals,
users should always:
- work in well-ventilated areas.
- wear appropriate safety equipment and clothes that are
specifically designed to filter out microscopic particles.
WARNING
1. The tool shall not be used in potentially explosive
atmospheres.
2. Disconnect the air hose before changing or adjusting
any inserted tools.
3. Before using tool, please confirm all couplings and
plugs are fixed securely. An air hose that is under
pressure may lash out when disconnected and could
lead to serious injuries.
4. Prevent loose clothes, long hair or any other personal
accessories from coming close to moving parts to
reduce the risk of being caught, trapped or drawn into
the rotating spindle.
5. Excessive high air pressure that exceeds the
maximum pressure may cause injuries to user.
6. Exposure to strong vibration for extended time may
cause harm to operator.
7. Be aware of the rotation direction before starting the
tool to reduce hazardous situations due to unexpected
rotation direction.
8. WATCH YOUR STEP! Leaving excess hose
unattended near working area or walk path could
result in injury or death.
9. Wearing eye/face protection could reduce the danger
to person from high speed splinters being emitted from
the tool or work surface.
10. Wearing correct breathing protection will help avoid
inhaling dust or debris from work process that can be
harmful to your health.
11. High sound levels can cause permanent hearing loss.
Use hearing protection while operating tool.
12. Due to the material being processed, there may be a
risk of explosion or fire. Be aware of work surface
dangers prior to beginning work.
13. There is a risk of being cut due to high speed rotation.
Do not touch high speed rotating disc.
14. This power tool is not insulated. If contact is made with
an electric current, injury may occur.
15. Dust created by sanding, sawing, grinding, drilling and
other related activities may expose the user to dust
and/or microscopic particles that may contain
chemicals known to the State of California to cause
cancer, birth defects or other reproductive harm.

The oil and water extractor should not be mounted on or
near the air compressor.
The temperature of air is greatly increased during
compression. As the air cools down to room temperature,
in the air line, on its way to the Air Power Tool, the moisture
contained in it condenses. Thus, for maximum effectiveness,
the oil and water extractor should be mounted at some point
in the air supply system where the temperature of the
compressed air in the line is likely to be lowest. Air lines must
be properly drained daily. Each low point in an air line acts as
a water trap. Such points should be fitted with an easily
accessible drain. See diagram below. Pitch all air lines back
towards the compressor so that condensed moisture will flow
back into the air receiver where it can be drained off.
Drain daily.
