4.6 Auxiliary Hydraulics
The PT-100 models come equipped with an
auxiliary hydraulic system designed to power
approved hydraulic attachments.
To operate, connect the attachment to the
quick couplers (fig. 4.6-1). To release resid-
ual pressure in the system, press the button
labeled 1 (fig. 4.6-1).
1. Pressure release valve
2. Case drain coupler
3. High flow couplers
4. Low flow couplers
The auxiliary hydraulics can be engaged intermittently or continuously depending
on the requirements of the attachment being utilized.
To engage the low flow auxiliary circuit intermittently, press the toggle switch on
the top of the right joystick (item 5) to the right or left of center to control flow
direction (fig. 4.6-2).
To engage the low or high flow auxiliary circuit continuously, activate the switch
for the desired circuit on the dash panel, labeled 6 or 7 in figure 4.6-3.
Note: Moving any of the the auxiliary switches from one position to the other has
the effect of reversing flow through the circuit.
Note: The continuous flow switches must be in the neutral position in order to
start the engine.
Note: The continuous flow auxiliary switches have an orange locking device that
must be disengaged before the switch will activate.
