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.
This section describes how the operator can identify
and operate the lower controls.
CONTROL SELECTOR LEVER - 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.
BOOM CONTROL LEVERS - 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 SWITCHES - The electric
controls are arranged as shown in Figure 4.4 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. The engine start/stop control is operated by a
three-position toggle switch.
To start the engine from the lower controls,
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 lower controls,
push
the toggle to “START/STOP” again. Allow the toggle
to return to the neutral or centered position. Refer
to Section 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. 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 lower controls,
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 lower
controls,
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 ground,
push the toggle switch to the “ON” position and
operate the appropriate lift controls.
To deactivate the backup pump from the ground,
push the toggle switch down (towards the “30
SECOND INTERMITTENT” message).
