This section explains the steps to be taken in case of an emer-
gency situation during operation.
5.2 EMERGENCY OPERATION
Operator Unable to Control Machine
IF THE PLATFORM OPERATOR IS PINNED, TRAPPED OR UNABLE
TO OPERATE OR CONTROL THE MACHINE:
1. Other personnel should operate the machine from
ground controls only as required.
2. Only qualified personnel in the platform may use the
platform controls. DO NOT CONTINUE OPERATION IF
CONTROLS DO NOT FUNCTION PROPERLY.
3. Rescue equipment can be used to remove the plat-
form occupant. Cranes and forklifts can be used to sta-
bilize motion of the machine.
Platform Caught Overhead
If the platform becomes jammed or snagged in overhead struc-
tures or equipment, rescue the platform occupant prior to free-
ing the machine.
5.3 PLATFORM MANUAL DESCENT
The platform manual descent valve is used in the event of total
power failure to retract and lower the platform using gravity.
The manual descent valve is located at the bottom of the mast
assembly on the front of the machine inside an access hole.
Look for the instruction decal located just above the access
hole. (See Figure 5-1.)
The procedure is as follows:
1. Locate the manual descent valve on the front of the
machine at the base of the mast.
KEEP HANDS AND ARMS OUT OF THE PATH OF THE MAST AND PLATFORM
WHILE LOWERING.
2. Press and hold the RED button on the manual descent
valve, release the button when the platform is lowered
to desired level.
