Terex PT60CE, Operation And Maintenance Manual

4.8 Bucket Positioning (optional)
The PT-60 machines can be equipped with feature commonly referred to as
“bucket positioning”. The bucket positioning system does not automatically level
your attachment. Instead, it will maintain the current angle of the quick attach
(relative to level) throughout the upward cycle of the lift arms.
The bucket positioning feature can be turned on or off with the switch located on
the dash panel (item 23, section 4.1 ).
Note: During the upward cycle, the bucket positioning function can be overridden
by operating the tilt or curl functions of the joystick.
Note: The bucket positioning feature works on the upward cycle only. The opera-
tor must position the attachment manually on the downward cycle.
4.9 Remote Lift Arm Valve
The lift arms on the PT-60 can be lowered from the exterior of the machine in an
emergency.
To lower lift arms:
1.
Make sure all bystanders are clear of the normal movement path of the lift
arms and any attachment that may be fastened to the quick attach.
2. Make sure the engine is off and all moving components have stopped.
3. Open the hood at the rear of the machine.
4. Insert the proper size hex (allen) type wrench into the bleed screw on the
remote lift arm valve (RLV) mounted to the left side of the hydraulic
reservoir (fig. 4.9-1).
5. Make sure you can see the lift arms, then turn the bleed screw CCW to
release pressure and slowly lower the lift arms. Turn the screw CW to close
the valve when the lift arms have come to rest on lift arm stops.
