5.1 - IN CASE OF POWER LOSS
In the event of power loss, control system failure or other malfunction, boom lowering functions
may be accomplished manually.
To manually operate boom retraction, and turntable rotation functions, use the hand pump,
and "motion selection" valve on the hydraulic pump unit that can be accessed inside the pump
compartment.
Manual lowering of the boom and platform may also be performed by actuating the valve
plunger found on the base of each boom lift cylinder. Pushing in and holding the valve "button"
on the appropriate cylinder retracts that cylinder, thereby retracting that part of the boom. The
boom may need to be rotated to a clear area before lowering.
In an emergency, if the operator has to exit the platform while it is elevated, the transfer of the
operator must respect the following recommendations :
•
Exit on
to a sturdy and safe structure.
•
Allowance must be made for the possibility of boom deflection when egressing from the
platfo
rm.
•
The occupant(s) must ensure that 2 lanyards are used for security/safety. One must be
attached to the designated anchorage point on platform the occupant(s) is in and the other
attached to the structure intended to get on
.
• Do not lea
ve platform without taking into account the allowance for possibility of boom
deflection when exiting platform
.
•
Occupant(s) must exit the current platform through the normal
access.
N.B.-:-D
O NOT DETACH THE LANYARD FROM THE CURRENT PLATFORM IF THE TRANSFER TO THE
NEW
STRUCTURE POSES ANY DANGER OR UNTIL THE TRANSFER IS SAFELY COMPLETED. DO NOT
ATTEMPT
TO CLIMB DOWN THE BOOM. INSTEAD WAIT FOR ASSISTANCE FOR A SAFE EXIT.
