Auxiliary Hydraulics
The PT-50 and PT-60 models come
equipped with an auxiliary hydraulic gear
pump. This pump has a maximum rating
of 17.44 gpm.
To operate, connect the attachment to
the two quick couplers (photo C). To
release any pressure in the system,
press the button labeled 1 in photo C.
The auxiliary hydraulics can be engaged
intermittently or continuously depending
on the requirements of the attachment
being utilized.
To engage the hydraulic flow intermit-
tently, activate the toggle-type switch on
the top of the right joystick, photo D.
Intermittent function is ideal for attach-
ments such as grapple buckets and
dozer blades.
To engage the hydraulic flow continu-
ously, activate the 3-position switch on
the dash panel, labeled 2 in photo E.
Continuous function is ideal for attach-
ments such as snow blowers, brush cut-
ters or backhoes.
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.
