If the emergency lower is used due to a machine defect, do not use the machine.
Contact your local Snorkel representative.

!
If the emergency lower is used, the top and bottom booms must be fully
extended then fully lowered before work can continue.
After emergency lowering, any further powered lowering could cause an
airlock in the hydraulic system. This could cause the hydraulic operation
to fail.
All booms must be fully extended/raised, then lowered before work can
recommence.
EMERGENCY LOWERING HAND PUMP
The emergency hand pump lowering procedure is available from the lower control station. In the
event of a power failure, the hand pump procedure to use is as follows:
•
Insert the hand pump lever into the pump shaft (refer to Figure 2-18).
•
Move the platform raise/lower lever to the required direction of movement and operate the hand
pump.
•
Continue pressing down on the platform raise/lower lever when the machine starts to lower.

EMERGENCY LOWERING SWITCH
The Emergency lowering switch can be used to lower the platform from the lower controls in situa-
tions where the boom levers malfunction (refer to Figure 2-19).
Note
The emergency lowering switch relies on the electrical system. The switch will not function if the electri-
cal system is faulty.
•
Turn the switch clockwise to lower the top boom.
•
Turn the switch anti-clockwise to lower the lower boom.
