IN THE EVENT THAT ALLEN WRENCHES FOR LOWERING THE TOWER CANNOT BE
FOUND THE TOWER MUST BE LOWERED BY REMOVING THE ACTUATOR MOUNT PINS:
Rotate to center without the lowering tools
Slowly apply pressure to the rotation platform to manually rotate to the centered position. Trying to
rotate the platform too quickly or with too much pressure can break the rotation motor shaft or cause the
toothed drive belt to shear a tooth. The upper stage can be rotated in either direction.
Generally, you need to rotate the platform in the direction that requires the least amount of travel in
order to center the platform.
Retract the lower stage without the lowering tools
Support the Midplate (rotation) assembly with temporary blocking to relieve the tension on the lower
actuator pivot pins.
Using a small at blade screwdriver or needle-nose pliers,
remove the retaining rings that secure the lower pivot pin
in place.
Use a brass drift punch to remove the pivot pin from the
extension end of the actuator. Avoid using a hardened steel
punch which could peen the end of the shaft thus damaging the
bore within the aluminum pivot blocks.
Note that the light weighs in excess of 100 pounds, use caution.
Apply upward pressure on the main lift arm to remove support blocking then slowly lower the lift arm
allowing the actuator shaft to extend past the lower pivot blocks.
Retract the upper stage without the lowering tools
Support the lamp tree with temporary blocking to relieve the tension on the upper actuator pivot pins.
Using a small at blade screwdriver or needle-nose pliers, remove the 4 e-clips securing the lower pin
of the upper actuator.
Support the lamp tree. Depending on conguration, the weight
of the lamp tree may exceed 50 lbs. Use a brass drift punch to
remove the pin.
Lift up on lamp tree to remove support blocking. Rotate the
actuator towards the front of the light. The upper stage will not
be completely lowered but should provide ample clearance to
transport the light.
Cushion and secure the actuators and other components as
necessary before transporting.
New retaining rings must be installed before returning light
to service.
