the turntable in a clockwise or counterclockwise direc-
tion. The switch is spring returned to the center off posi-
tion.
Hold the switch to the right to rotate the turntable coun-
terclockwise. Hold the switch to the left to rotate the turn-

lower the jib. The switch is spring returned to the center
off position.
Hold the switch up to raise the jib. Hold the switch down
to lower the jib.
Note
The jib and platform rotate functions can not be oper-
ated at the same time. The platform rotate function will
override the jib function.
Platform Level Switch

level the platform floor with respect to the ground. The
switch is spring returned to the center off position.
Hold the switch up to tilt the platform floor upward or
away from the ground. Hold the switch down to tilt the

Engine/Emergency Power Switch
Hold the engine/emergency power switch (refer to Figure
6.2) down to operate aerial platform functions using the
emergency power system. Release the switch to disen-
gage the emergency power system.
Note
The emergency power system is for lowering the platform
during an emergency and is not intended for normal ma-
chine operation.
If the engine is running, it will stop when the switch is
placed in the emergency power position.
Throttle Switch
The throttle switch (refer to Figure 6.2) is used to set the
engine throttle speed to either low or high idle.
Place the switch in the low position before starting the
engine and in the high position for machine operation and
for engine and/or hydraulic system warm-up.
The engine has a two speed throttle operation from the
lower controls. When the throttle switch is in the low
position the engine is at idle. Placing the switch in the
high position increases the engine speed to mid-range.
Placing the ground controls switch in the on position also
increase the engine speed to mid-range.
Circuit Breaker Reset Buttons
The wiring box next to the lower control panel has a cir-
cuit breaker for the main, run, and throttle control cir-
cuits. There is a reset button for each circuit breaker on
the front of the wiring box (refer to Figure 6.3).
