the work area to avoid accident or injury.
●Some tools generate high noise levels.
Check to be sure that the use of this tool conforms
to all local noise regulations.
BEFORE OPERATION
●Inspect tool before use.
Before using, check that screws are securely
tightened, that any protective cover or guard is
securely in place, other parts are free from damage
and that the tool runs as it should.
Check that moving parts are properly adjusted for
positioning and tightened, that parts are free from
damage and properly mounted, and that all other
parts are in good condition for normal operation.
Should you find any damage to the protective
cover or other part, replace it in accordance with
the Operation Manual. If there are no instructions
in the Manual, please contact the sales agent
through which you have purchased your tool or an
authorized dealer near you for repair.
Likewise, if a switch failure occurs, contact sales
agent through which you have purchased your tool
or an authorized dealer near you for repair. .
Do not use the tool if it does not start or stop with
the start/stop switch.
●Securely mount cutter
An improperly mounted cutter may fly out, causing
possible damage to the tool or injury to the operator.
●Always remove spanner, wrench, etc., once
adjustment has been made with them.
●Use a tool appropriate for the application.
Avoid heavy-duty application that is beyond the
capacity of the tool.
●Do not use the tool for purposes other than what
it is designed for.
●Do not abuse tool.
Use tool in accordance with the specifications: youʼll

advised that the tool is disassembled, degreased and
parts separated by material and recycled locally in
the appropriate manner.
GENERAL: PNEUMATIC
TOOLS
WARNING
●Use appropriate air pressure.
Excessively high air pressure will increase the
number of revolutions or strokes causing not only
potential premature failure/breakage but could also
lead to an unexpected accident or injury.
●Connect tool to air supply line.

4 AIR SUPPLY
CAUTION
●Draw off drainage before starting operation. If
the drainage enters into the tool, it can freeze
around the exhaust port of the tool and result in
output power reduction.
4-1. Air Pressure
Adjust air pressure to 0.6MPa (or 6 kgf/cm2) with
the air regulator. Lower pressure may result in
insufficient performance. Higher pressure may result
in premature wornout of parts. It is important to
maintain the proper pressure with pressure regulator
on air line.
4-2. Air Line (Fig.2)
Use a 9.5 mm (3/8”) I.D. air hose between the
compressor and the tool. Compressed air comes
to be cooled down and its drain be separated, as
soon as the air leaves the compressor. The drain,
however, is condensed in the piping, and can
enter into the tool mechanism, and may cause
malfunction.
So, install an air filter and an oiler between the
compressor and the tool.
4-3. oiler
Install an oiler between the compressor and the tool.
Use machine oil ISO VG-10 for lubrication and rust
prevention. Negligence of the oil supply may cause
damages on the tool. Lubricating the tool with high
viscosity oil reduces the tool performance.
4-4. Lubrication (Fig.2)
Before starting the tool, disconnect air hose from
the tool and supply a few drops of machine oil ISO
VG-10 to the air inlet port of the tool. Then reconnect
and make idle running for a few seconds so that the
oil should reach every part in the tool.
