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. Re-
lease 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 tereain.
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.
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 consider-
ation all obstructions on the ground and overhead
and avoid them.
