Platform Rotator
How to Remove the Platform
Rotator
Note: When removing a hose assembly or fitting,
the O-ring (if equipped) on the fitting and/or hose
end must be replaced. All connections must be
torqued to specification during installation. Refer to
Specifications,
Hydraulic Hose and Fitting Torque
Specifications.
1 Remove the platform.
2 Tag, disconnect and plug the hydraulic hoses
from the platform rotate manifold.
Bodily injury hazard. Spraying
hydraulic oil can penetrate and
burn skin. Loosen hydraulic
connections very slowly to allow
the oil pressure to dissipate
gradually. Do not allow oil to
squirt or spray.
3 Support the platform mounting weldment. Do
not apply any lifting pressure.
4 Remove the six mounting bolts from the
platform mounting weldment. Remove the
center bolt and slide the platform mounting
weldment off of the platform rotator.
5 Support the platform rotator with a suitable
lifting device. Do not apply any lifting pressure.
6 Remove the pin retaining fasteners from the
jib boom and leveling links to platform rotator
pivot pins. Do not remove the pins.
7 Support the jib boom, jib boom cylinder and
leveling links with an overhead crane.
8 Use a soft metal drift to drive both pins out,
then remove the platform rotator from the
machine.
Crushing hazard. The platform
rotator could fall when removed
from the machine if not properly
supported.
Note: When installing the platform rotator, be sure
to torque the fasteners to specification. Refer to
Specifications,
Machine Torque Specifications.
How to Bleed the Platform Rotator
Note: This procedure will require two people.
1 Move the function enable toggle switch to
either side and activate the platform rotate
toggle switch to the right and then to the left
through two platform rotation cycles. Then
hold the switch to the right position until the
platform is fully rotated to the right.
2 Place a suitable container underneath the
platform rotator.
3 Open the top bleed screw on the rotator, but
do not remove it.
Bodily injury hazard. Spraying
hydraulic oil can penetrate and
burn skin. Loosen hydraulic
connections very slowly to allow
the oil pressure to dissipate
gradually. Do not allow oil to
squirt or spray.
