4.6 Auxiliary Hydraulics

The PT-50/60 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).
The auxiliary hydraulics can be engaged
intermittently or continuously depending on
the requirements of the attachment being utilized.
To engage the hydraulic flow intermittently, activate the toggle-type switch on the
top of the right joystick (fig. 4.6-2).
To engage the hydraulic flow continuously, activate the 3-position switch on the
dash panel, labeled 2 in figure 4.6-3.
Note: Moving either switch from one position to the other has the effect of
reversing flow through the auxiliary hydraulic circuit.
Note: The continuous flow switch must be in its neutral position in order to start
the engine.
Note: The continuous flow auxiliary switch has a small orange locking switch that
must be disengaged before the switch will activate.
