8.4 Trapped Air Removal
Before placing a new cutter into operation, cycle the
piston several times without load to remove any trapped
air in the hydraulic circuit. The tool should also be placed
below the pump so the air can escape to the pump
reservoir.
Air is completely purged when the piston advances and
retracts smoothly in both directions, from fully extended
to fully retracted.
This procedure may also be performed after the cutter
has been serviced.
Refer to the cutter controls information in Section 8.6 of
this manual when performing the air removal procedure.

Position the material to be cut between the
cutter blades, so that it is perpendicular
to the piston axis, as shown in Figure 9.
This will provide the best quality cut while
placing the least amount of load on the
cutter.
Adjust the support bolt as needed. Head
of support bolt should just touch the
surface of the material to be cut, when
the item is positioned against the fixed
blade of the cutter.
After adjusting the support bolt, be sure
that the support bolt retaining nut is snug
tight against the support bolt mounting
ear. This will help prevent support bolt
movement during cutting.
NOTICE
Be certain that the hardness,
tensile strength and diameter of the
material to be cut are within allowable
limits. Refer to the chart in Section 2.1 of
this manual for additional information.
Failure to observe this instruction may
result in poor cutting performance and/or
damage to the cutter.

9.5.2 Moving Blade Replacement
Replace the moving blade as described in the following
steps:
1. Start the pump. Extend the piston to allow access to
the moving blade and screws. See Figure 14.
2. Stop the pump. Be sure that hydraulic pressure is
completely relieved.
3. Disconnect pump from AC power supply.
9.5 Blade Replacement
The use of worn blades decreases the eectiveness of
the cutter and can also side load the cylinder, possibly
damaging the tool. Pump overheating may also occur.
Replace blades immediately when it is noticed that
they are worn and/or damaged, or if there has been a
noticeable decrease in cutting performance.
The cutter contains a fixed blade and a moving blade.
Refer to Section 9.5.1 for fixed blade replacement
instructions and to Section 9.5.2 for moving blade
replacement procedures.
NOTICE:
CAUTION
Use extreme caution when removing
and installing blades. Blades may be sharp even
when worn. To avoid hand injury, wear appropriate
hand protection and avoid contact with blade cutting
edges.
NOTICE
To help ensure even blade wear and optimum
cutting performance, it is recommended that both the
fixed blade and the moving blade be replaced at the
same time.
9.5.1 Fixed Blade Replacement
Replace the fixed blade as described in the following
steps. Refer to Figure 13, items 1 and 2.
1. Start the pump. Move the piston to the “home”
position (fully retracted). See Figure 8.
