Override Switch

The override switch at the upper controls may be used
to override the platform overload and the Snorkel Guard
system, when either one is activated.
When the platform overload system is activated, the
override or the emergency power switch (refer to Figure
10.3) at the upper controls may be used to override the
system to operate riser up/down, main boom up/down/
retract, jib boom up/down, or turntable rotation and drive
functions. The switch is spring returned to the normal
operation position.

When the Snorkel Guard system is activated, the override
switch (refer to Figure 10.3) at the upper controls may be
used to override the system to operate riser up/down, main
boom up/down/retract, jib boom up/down, or turntable
rotation functions.
The lower controls are not affected by the Snorkel Guard
activation.
Warning
The potential for an accident increases when safety
devices do not function properly. Death or serious
injury could result from such accidents. The override
switch must only be used when all controls are re-
leased and in the neutral position. If a zero or neutral
state cannot be achieved, depress the emergency
stop and obtain assistance at the lower controls.
1. When the machine is stopped due to activation of
the Snorkel Guard system or overload, immediately
depress the emergency stop, release the foot switch
and all controls. Perform an assessment of the situ-
ation which caused the system to activate.
2. If it is determined that all controls are released and
operation can proceed, return the emergency stop
to the on position, and activate the override switch.
3. Activate the foot switch.
4. Activate the necessary functions to move the platform
away from the obstacle that caused the Snorkel
Guard activation or if due to an overload fault, retract
the booms then lower in a safe condition.
5. Assess the machine for any damage. If damage
occurred, return to the stowed position, exit the unit
and perform a thorough inspection before returning
to service.
