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.
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.
Turn chassis key switch to platform, and turn on (turn
1.
clockwise) the chassis emergency stop switch.
2. Mount the platform, close and latch the gate.
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 consideration all obstructions on the ground and overhead
and avoid them.
4
Once you have moved the machine to a firm level
surface as near as possible to the work area, follow
the instructions on page five to position the platform
as close to the work area as possible.
Always, before operating any function, check the
area around and overhead for any obstructions or
electrical conductors.
NEVER exit the platform while the boom is
elevated. Keep both feet firmly planted on
the platform floor at all times.
Multifunction Controls
The UpRight AB-46 RT employs the use of
multifunction controls. This means that riser or boom
extension will function at full speed while
simultaneously operating upper boom, jib, turret, or
rotating the platform.
The turret may be rotated while driving when boom is
lowered if necessary to make turns in tight areas.
No other boom functions will operate while driving.
Rotating the Turret
1. Set the function speed control dial to the desired
setting. Rotate the dial clockwise to increase
speed, counterclockwise to decrease. If you are
not sure what speed to use, start out slow; the
speed can be varied while operating the function.
2. While depressing the foot switch, turn the turret
rotation control switch counterclockwise to rotate
left, clockwise to rotate right. Release the switch
to stop rotation. Observe the area around the
boom when rotating the turret to avoid any obstructions.
Elevating the Riser
Lower Control Operation
All boom functions will operate at fixed speed. Those
which are adjustable will operate at the speed set on
the platform control.
1. Turn chassis keyswitch to chassis controls.
2. With engine running, operate boom control
switches to position the platform.
Leveling the Platform
DO NOT operate the machine if the platform
does not maintain level when elevated.
Note: Platform leveling can be performed only
with the boom stowed and should be done only
to calibrate the automatic leveling system.
1. Set the function speed control dial to the desired
setting. Rotate the dial clockwise to increase
speed, counterclockwise to decrease. If you are
not sure what speed to use, start out slow; the
speed can be varied while operating the function.
2. While depressing the foot switch, push the
platform level control switch forward to swing the
platform upward, rearward to swing the platform
downward. Release the switch to stop leveling.
1. While depressing the foot switch, push the riser
control lever forward to elevate the riser, rearward
to lower the riser. Release the control lever to
stop elevating / lowering. The riser will function at
a constant speed, function speed control setting
is not necessary.
Elevating the Upper Boom
1. Set the function speed control dial to the desired
setting. Rotate the dial clockwise to increase
speed, counterclockwise to decrease. If you are
not sure what speed to use, start out slow; the
speed can be varied while operating the function.
2.
While depressing the foot switch, push the upper
boom control lever forward to elevate the upper
boom, rearward to lower the upper boom. Release
the control lever to stop elevating / lowering.
