Engine/Emergency Power Switch
The engine/emergency power switch (refer to Figure 6.6)
is spring returned to the engine position for aerial plat-
form engine operation.
Place the switch in the emergency power position and
hold to operate aerial platform functions using the emer-
gency power system. Release the switch to disengage
the emergency power system.
Note
The emergency power system is for lowering the plat-
form during an emergency and is not intended for normal
machine 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 6.6) is used to set the
engine throttle speed to either low or high idle.
Place the switch in the low position for normal machine
operation and in high to drive at maximum speed.
The engine has a three speed throttle operation from the
upper controls. Independent of the throttle switch, the
platform foot switch, when depressed, increases the en-
gine speed from low to mid-range.
High engine speed is obtained when the main boom is
horizontal, the foot switch is depressed, the throttle switch
is in the high position, and the drive joystick is moved out
of neutral into the forward or reverse position.
The machine can be driven in mid-range engine speed
with the throttle switch place in the low position.
Horn Button
The optional horn button is on the right side of the upper
control panel. Press the button to sound the horn.
Platform Foot Switch
The upper controls are interlocked through the platform
foot switch (refer to Figure 6.7). Step down on and hold
the platform foot switch to activate the drive and boom
functions from the upper controls.

outlet at the platform. Place the switch in the machine
position to turn off the generator and resume machine
operation.
Machine functions will not operate while the switch is in
the generator position.

operated using gasoline or liquefied petroleum gas (LPG).
Dual fuel machines have a gasoline and an LPG tank

ate the engine using gasoline.
