4.13 Lowering the Tower
Overview
A low-voltage electrical circuit controls the release of pressure in the hydraulic
cylinder (c). When pressure is released, the tower will lower.
Notes
The engine does not need to be running to lower the tower.
The hydraulic circuit includes a pressure release valve that lowers the tower in
an emergency situation. See topic Emergency Shutdown Procedure.
If the parking brake on the trailer is disengaged while the tower is raised, it will
lower automatically.
Procedure
Perform the procedure below to lower the tower.
1. Stop the engine.
2. Turn off the circuit breakers (a, b).
3. Press and hold the lower half of the tower switch (d). Release the switch when
the tower is completely lowered.
WARNING
Personal injury hazard. Raising or lowering the tower creates situations that if not
avoided, will cause death or serious injury from striking, crushing, pinching,
electrocution, etc.
f Keep the area under and around the lights clear of people and obstructions
while raising and lowering the tower.
