ACCESSORIES
DEMAND THROTTLE
A demand throttle will increase the engine RPM automatically when a control is actuated. This signals the
engine speed to increase therefore the pump output increases. The throttle activation used, electric or
hydraulic, will depend on vehicle engine.
ENGINE STOP/START CONTROL (OPTIONAL)
The engine stop/start system allows the truck engine to be stopped and restarted from remote locations.
Controls may be located in the cab, at the outrigger control location, at the pedestal or lower controls, or in
the platform.
Before attempting to start the engine, make sure the transmission is in neutral, the parking brake applied,
and the wheels are chocked.
To start the engine make sure the vehicle key is in the run position and the master switch in the cab is “ON”.
Push the control labeled “ENGINE” and hold until the engine starts, then release.
The engine will crank as long as the switch is held in the “START” mode. If it fails to start, release and let the
starter cool down. The control toggles between start and stop mode, so it is necessary to push and release,
then push again to crank the engine if the engine fails to start.
To stop the engine push the switch and then release. Refer to Emergency Operation for further information
on the use of this control in an emergency.
TWO-SPEED THROTTLE CONTROL (OPTIONAL)
The two-speed throttle control allows the engine speed to be increased to a high idle position or reduced to
the normal idle speed from remote locations. This gives the operator a choice of an efficient, economical
engine idle speed with slower boom movement or a faster engine speed with faster boom movements when
required. Controls may be located at the outrigger control location, at the pedestal or lower controls, or in the
platform. The control will alternate the engine speed between the high and standard idle speeds.
• To increase engine speed, push the switch or air plunger and release.
• To decrease engine speed to an idle, push the switch or air plunger and release.
NOTE: The two-speed throttle is not required when the Aerial Device is ordered if the Aerial
Device is equipped with a “demand throttle” which increases engine speed automatically
when a control is activated.
AUXILIARY LET DOWN POWER CONTROL (OPTIONAL)
If the power source for the Aerial Device fails, the auxiliary let down power control activates power to stow
the Aerial Device if the vehicle electrical system and the hydraulic system is operable. The auxiliary let down
power control is combined with the two-speed throttle control. If the engine is not running, the auxiliary let
down power is turned on and off by pressing and holding or releasing the two-speed throttle push button. If
Aerial Device is not equipped with the two-speed throttle, the control only operates the auxiliary let down
power.
NOTE: The auxiliary let down power system should not be operated longer than 30 seconds
continuously. Continuous use will drain the battery and damage (overheat) the auxiliary
pump motor.
