Driving
With Boom Lowered
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. Depress the foot switch and move the drive
control handle forward to travel forward and
reverse to travel in the reverse direction.
7. While driving, press the differential lock button,
located on the front of the drive control handle,
as necessary for improved traction.
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 chas-
sis. They will indicate the direction of travel
when the drive control handle is moved.
With Boom Elevated
Travel with boom elevated is restricted to firm
level surfaces only.
When driving elevated, the machine will travel at
creep speed (1/2 foot [.15 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.
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 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 if necessary
to make turns in tight areas. All other boom func-
tions will not operate while driving.
Lower Control Operation
All boom functions will operate at fixed speed.
1. Turn chassis keyswitch to chassis controls.
2. With engine running, operate boom control
switches to position the platform.
