Starting the engine
From the lower controls
1. Turn the chassis key switch to chassis position.
2. Press the start button to crank the engine. Release
when the engine starts.
3. When the engine is cold: press and hold the preheat
button while starting the diesel engine.
Note: Do not depress the foot switch when cranking
engine, as this may flood engine.
From the platform controls
1. Turn the chassis key switch to platform controls.
2. Turn the platform keyswitch fully clockwise to crank
the engine. Release when engine starts.
3. When the engine is cold: Press and hold the preheat
button while starting the diesel engine.
Note: Do not depress the foot switch when cranking
engine, as this may flood engine.
Driving
With Boom Lowered
The AB-46 RT has two drive speeds when the boom is
lowered to efficiently accommodate varying terrain.
Lo Speed: The Lo speed capability allows the machine
to be easily maneuvered through rougher
terrain and negotiate steeper slopes.
Hi Speed: The Hi speed capability is convenient for
maneuvering in areas that are relatively
smooth and where the machine will not be
driven over rough or sloping terrain.
1. Turn chassis key switch to platform, and turn on
(turn clockwise) the chassis emergency stop switch.
2. Mount the platform, close and latch the gate.
3. Attach approved fall restraint to designated platform
anchorage point. Attach only one fall restraint to
each point.
4. Start engine.
5. Check that the area around and above the work
platform is clear of obstructions, holes, drop-offs,
persons in the route of travel, and the surface is
capable of supporting wheel loads.
6. Examine the terrain and place the speed selector
switch in the appropriate position (Hi or Lo).
7. Depress the foot switch and move the drive control
handle forward
to travel forward and reverse
to travel
in the reverse direction.
8. While driving in HI speed, pressing the button,
located on the front of the drive control handle, will
shift momentarily into LO for improved torque.
Note: When the boom is rotated to the front of the
chassis (steering wheels aft) directions of travel and
steering will be reversed. Observe the color coded
arrows on the control panel near the drive control
handle, and on the chassis. They will indicate the
direction of travel when the drive control handle is
moved.
The front axle will oscillate freely through a limited
range when driving for greater ease of negotiating
irregular terrain.
With Boom Elevated
Travel with boom elevated is restricted to firm level
surfaces only. When the articulating front axle is not
level, it will lock into position and disable the drive
function. Drive is disabled above 8m (26ft).
When driving elevated, the machine will travel at creep
speed (1 foot [.3 m] per second).
Steering
1. While depressing the foot switch, push the steering
switch (located on top of the control handle) to the left
to turn left, and right
to turn right.
Note: Steering is not self centering. Wheels must
be returned to the straight ahead position by
operating the steering switch.
POSITIONING THE PLATFORM
Positioning the platform as close as possible to the work
area requires some planning. First, you must survey the
work site to find a suitable place to park the machine.
This must be a firm level area as close as possible to
the work area. Take into consideration all obstructions
on the ground and overhead and avoid them.
