8.6 Cutter Controls
Two push buttons control cutter operation. One push
button is for the advance function and the other push
button is for the retract function.
With the pump motor ON:
• Press and hold the
advance push button to advance
the piston and slide the moving blade forward. See
Figure 10.
• Press and hold the retract push button to retract the
piston and slide the moving blade backward. See
Figure 11.
• Release either push button at any time to stop
movement of the piston and moving blade. Be advised
that there may be a brief delay for the piston and blade
to make a complete stop.
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.
8.5 Positioning Material
Always be sure that the piston and moving blade are in
the fully retracted “home” position before placing any
material inside the cutting head. See Figure 8.

Figure 8, Piston and Blade in Home Position
(fully retracted)
Open the cutting head and place the material inside.
Then, close the cutting head. Refer to Section 7.2 for
additional information.
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.
NOTICE
Be certain that the diameter of the material to
be cut does not exceed the maximum allowable diameter
specified for your cutter model. Refer to the chart in
Section 2.1 of this manual for additional information.
Faliure to observe the instruction may result in poor
cutting performance and/or damage to the cutter.
