LOWER CONTROL OPERATION

DANGER:

 

DEATH OR SERIOUS INJURY

MAY RESULT IF CHASSIS BECOMES
ENERGIZED.  DO NOT OPERATE THE AERIAL
DEVICE WHILE CREATING A PATH TO THE
GROUND.

The Lower Controls are located on the turret  as shown
Figure 4.4.  The detented control selector is used to
select operation of the aerial lift from the upper or
lower controls, this also serves as the emergency
stop for the upper controls.  When a control station is
selected the other is one inoperable.  The remaining
control levers at the lower control station are spring-
loaded.  The lower control decal identifies the function
of each control lever and indicates which direction to
move the control lever for the desired movement.  When
released the control lever will return to the centered or
neutral position and motion ceases.

ELECTRIC SELECTOR STATION

 - The electric

controls are also part of lower control station mounted
on turret.   A description of each control and the
method of operation is given  below.

ENGINE START/STOP CONTROL (Standard)

 - The

engine start/stop control is convenient for the ground
crew at the turret.  The engine start/stop control is
operated by a three-position toggle switch.

To start the engine from the turret

, push the toggle

to the “START/STOP” position and hold the toggle in
that position for a moment until the engine starts.
Allow the toggle to return to the neutral or centered
position.

To stop the engine from the turret

, push the toggle

to “START/STOP” again.  Allow the toggle to return to

the neutral or centered position.  Refer to Chapter 5,
“Emergency Operation” for information on the use of
this control in an emergency.

TWO-SPEED MANUAL THROTTLE CONTROL
(Standard)

 - Gives the operator a choice of efficient,

economical engine idle speed or higher engine speed
when faster lift movements are required.  Slow speed
also provides the proper hydraulic flow for most
hydraulic tools.  The two-speed throttle control will
operate only if the master control is activated.  The
two-speed throttle control is operated by a three-
position toggle switch at the turret.

To speed up the engine from the turret

, push the

toggle to the “ENGAGE” position.  Allow the toggle to
return to the neutral or centered position.

To slow  the engine to an idle from the turret

,

push the toggle to the “DISENGAGE” position.  Allow
the toggle to return to the centered or neutral position.

BACKUP PUMP CONTROL (Option)

 - If the aerial

lift main power source fails, the backup pump option
can be activated to operate the lift.  The backup pump
control is a detented toggle switch located at the turret.

The backup pump system should not be operated
longer than 30 seconds continuously. 

 Continuous

use will drain the battery and damage (over heat) the
backup pump motor.

To activate the backup pump from the turret

, push
