1.The maximum recommended air pressure during operation must not exceed 90 psi (6.3bar). Higher air
pressure may create unsafe operating conditions for the tool and the user.
2.The compressed air should be cooled and have a water filter installed at the outlet end of the
compressor. Even with a water filter installed, some water may still condense in the piping or hose and
will enter the tool mechanism causing premature damage to the tool. Therefore, it is recommended to
install an air filter-lubricator device somewhere between the tool and the compressor.
3.Always use an air compressor of the proper capacity to operate each tool.
4.Clean the hose with a blast of compressed air before connecting the hose to the air tool. This will
prevent both moisture and dust inside the hose from entering the tool and causing possible rust or
malfunction.
1.Using these tools in any potentially explosive environment is strictly prohibited.
2.It is always recommended that these types of tools must be operated when standing on a solid or firm
location.
3.Always use these tools in a well ventilated area.
4.Slipping, stumbling and falling are the major causes of potential serious injury, therefore, a clean and
clutter free surface in the working area before operating the
tools is strongly recommended.
Read this manual carefully before installing, operating, servicing or
repairing.
Working environment:
Air supply and connection requirements:
Ideal system connection: Piping diameters and length requirement:
The diameter ΦA required for the inlet pipe is
recommended on the specification table.
The diameter ΦB required for the branch pipe
(from to ) should be 2 times as large as
ΦA. ΦB = 2 x ΦA
The diameter ΦC required for the primary air
supply (from to ) should be 3 times as
large as ΦA. ΦC = 3 x ΦA
The length for the inlet pipe should be less
than 15 feet (4.5m).
