ATTENTION.
A quick response to hydraulic line failure is important,
if the operator is to be safely removed from the
platform. The examples below describe some
emergency operating procedures to follow for some
specifi c types of hydraulic line failures.
1. The aerial lift design uses holding valves to
lock the position of the cylinders in the event
of a complete hydraulic line failure. This safety
feature prevents the booms from dropping.
The holding valve set screw and manual
rotation described earlier in this chapter can
be used to lower the booms.
2. If there is a continuous loss of hydraulic oil
from the aerial lift, operate the hydraulic power
source only while attempting to stow the aerial
lift to conserve the hydraulic oil. If operation of
any aerial lift function is not possible, then use
the holding valve set screw and the manual
rotation procedure described earlier in this
chapter.
ENGINE FAILURE - If the prime power source fails
the backup pump (option) can be used for emergency
operation. If this system is not installed, use the
engine start/stop control to crank the engine, as
previously explained. If this is not adequate, the
holding valve set screws and manual rotation must
be used.
HYDRAULIC PUMP FAILURE - If the primary
hydraulic pump fails use the backup pump, if so
equipped. If this feature is not installed, the holding
valve set screws and manual rotation must be used.
RESPONSIBILITIES AFTER EMERGENCY
OPERATION:
After any emergency situation it is the responsibility
of the operator to make sure the aerial lift is repaired
and adjusted by the service department before it is
used again.
If an equipment defect is suspected, do not allow
anyone to operate the aerial lift or enter the platform
until the problem is corrected.
