SECTION 6. EMERGENCY PROCEDURES
6.1 GENERAL
This section provides information on the procedures to be
followed and on the systems and controls to be used in
the event an emergency situation is encountered during
machine operation. Prior to operation of the machine and
periodically thereafter, the entire operating manual, includ-
ing this section, should be reviewed by all personnel
whose responsibilities include any work or contact with
the machine.
6.2 EMERGENCY TOWING PROCEDURES
Towing this machine is prohibited. However, provisions for
moving the machine have been incorporated. The follow-
ing procedures are to be used ONLY for emergency
movement to a suitable maintenance area.
1. Chock wheels securely.
2. Engage the mechanical release on both drive
brakes by loosening, completely reversing, and
tightening the three nuts on each brake.
3. Connect suitable equipment, remove chocks, and
move machine.
After moving machine, complete the following procedure:
1. Position machine on a firm level surface.
2. Chock wheels securely.
3. Disengage the mechanical release on both drive
brakes by loosening, completely reversing, and
tightening the three nuts on each brake.
4. Remove chocks from wheels as desired.
6.3 EMERGENCY CONTROLS AND THEIR
LOCATIONS
Emergency Stop Switch
There is red mushroom shaped switche located at the
Platform Controls Station. When depressed it will immedi-
ately stop all functions at that station and shut down the
machine.
CHECK DAILY TO MAKE SURE EMERGENCY STOP SWITCH IS
FUNCTIONING AND THAT CONTROL INSTRUCTIONS ARE IN
PLACE AND LEGIBLE.
Ground Control Station
The Ground Control Station is located on the right side of
the frame. The controls on this panel provide the means
for overriding the platform controls and for controlling the
platform lift up and down from the ground. Place the sta-
tion SELECT SWITCH in the GROUND position and oper-
ate the lift switch to lift up or down.
Manual Descent System
The manual descent system is used, in the event of total
power failure, to lower the platform using gravity. To oper-
ate the manual descent system, proceed as follows:
1. Turn knob (clockwise) on lowering valve until fully
closed.
2. Install handle, and pump until holding valve opens
and desired descent speed is attained.
3. When platform is fully lowered, turn knob on lower-
ing valve (counterclockwise) to reopen valve.
4. Return handle to stowed position.
6.4 EMERGENCY OPERATION
Use of Ground Controls
Know how to use Ground Controls in an emergency situa-
tion. Ground personnel must be thoroughly familiar with
the machine operating characteristics and the ground
control functions. Training should include operation of the
machine, review and understanding of this section and
hands-on operation of the controls in simulated emergen-
cies.
Operator Unable to Control Machine
NOTE: IF THE PLATFORM OPERATOR IS PINNED,
TRAPPED OR UNABLE TO OPERATE OR CON-
TROL MACHINE:
1. Operate the machine from ground controls only with
the assistance of other personnel and equipment
(cranes, overhead hoists, etc.) as may be required
to safely remove the danger or emergency condi-
tion.
2. Other qualified personnel on the platform may use
the platform controls. DO NOT CONTINUE OPERA-
TION IF CONTROLS DO NOT FUNCTION PROP-
ERLY.
