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/cm
2
) with
the air regulator. Lower pressure may result in
insuf
fi
cient 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 9.5mm (3/8”) I.D. [MLG-25] or 12.7 mm (1/2”)
I.D. [MLG-40, MLG-50, MLG-70] 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.
