INITIAL OPERATION
5.1 COMPRESSED-AIR CONNECTION
The OR-P 400 tools are designed to operate at an air
pressure between 5.7 to 6.2 bar.
Air pressure vs. performance
If the air supply pressure can be adjusted within a
range from 5.7 to 6.2 bar (85 - 90 psi) the OR-P 400
tool’s performance can be
fi
ne tuned to a particular
application or operation preferences. After an initial
„Break-In“ period, the air motor may become more
powerful. If the tool’s performance is effected by this
increase in performance, reduce the air motor output
by adjusting the tensioning force, refer to chapter 7.1.
5.2
AIR SUPPLY INSTALLATION
Motor and sealing piston are lubricated by oil mist of
the compressed air. Properly prepared compressed air
is therefore essential for trouble-free operation of the
tool. This can only be ensured by a reliably functioning
maintenance unit, consisting of water separator, pres-
sure reducing valve with pressure gauge and oil mist
lubricator.
The oil mist lubricator should supply suf
fi
cient oil. The
length of the hose between the tool and the main-
tenance unit should not exceed 5 m (15 ft). The internal
diameter of the pipe should be at least 10 mm (
3
/
8
“). It
must be ensured that the hose does not form loops,
where oil can collect.
a) Moisture
Moisture is always present in air lines due to conden-
sation within the lines as the air cools. Water in air lines
is a constant threat to the proper operation of air tool. A
good refrigerant type dryer is essential.
b) Lubrication
The air motor must be properly lubricated. This is
achieved by keeping the air line lubricator
fi
lled with oil
and correctly adjusted. Without proper lubrication, the
motor will become sticky and the tool will give low and
erratic tension and be dif
fi
cult to release from the strap.
NOTE: Some oils contain anti-wear additives which
may disable the air motor. Be certain to use recom-
mended oil.
Recommended oils are any good grade of rust and
oxidation inhibiting oil with a viscosity of 80-120 S.U.S.
at 100 degrees Fahrenheit.
Several drops of lubricator oil added to the inlet of the
air motor or into the air line each day will help insure
good operation. A noticeable reduction of air motor
performance can usually be corrected by squirting a
few drops of oil into the air line.
c) Cold weather operation
The tools operate reliably in a wide range of operating
temperatures. However, operating conditions below an
ambient temperate of 41°F (5°C) may require the
compressed air to be dried.
d) Air consumption
Air consumption in cubic feet per minute (cfm) for the
OR-P 400 tool can be calculated as follows:
4 x 5 x 0.40
=
8 cfm
4
= Number of straps applied per minute
5
= Number of seconds motor is on per strap
during tensioning, from start to deceleration
0.40
= VT ef

Con
fi
rm air pressure calibration by comparing it to a
master gauge placed in-line where the quick discon-
nect
fi
tting attaches to the tool.
Use the following information shown below for
comparing the various minimum air pressures while
the OR-P 400 tool cycles:
– Static
= 6.2
– Tension
= 4.1 (during take-up of strap)
– Stall
=
5.4
– Welding
= 5.2
5.3 SUSPENDING THE TOOL
The tool is equipped with a suspension bow, it can be
suspended on a spring balancer. The suspension bow
is designed to operate the tool horizontally or vertical-
ly.
