loose or missing hardware, and cracked welds.
3. Check tires for damage, punctures, and inflation;
tire pressure must be 75 psi.
4. Check all hoses / cables for wear.
5. Inspect elevating assembly for damage, deformation, buckled paint, loose or missing hardware,
and cracked welds.
6. Inspect platform and guardrails for damage,
deformation, buckled paint, loose or missing
hardware, and cracked welds. Insure that gate
operates freely and latches securely.
7. Check Hydraulic fluid level with platform fully
lowered.
8. Check battery fluid level (see battery maintenance, page 8).
DO NOT use a machine that is damaged or
malfunctioning. Tag and remove the unit
from service until it is repaired.
Note: Refer to figures 1 and 2 for chassis and
platform control locations.
1. Before performing the following tests, check area
around machine and overhead for obstructions,
holes, drop-offs, and debris.
2. Turn chassis key switch to chassis, and turn on
(rotate clockwise) emergency stop switches at
the chassis control panel and at the platform
control panel.
3. Push in the chassis emergency stop button and
operate any function switch at the chassis control
panel, function should NOT activate. Repeat for
platform emergency stop button, operating
chassis controls. Return both emergency stop
switches to the on position.
4. Operate each function switch to raise / lower,
extend / retract, rotate left / right, each section of
the elevating assembly and observe the operation of the machine. All functions should operate
through full cycle smoothly.
5. Turn chassis key switch to platform.
6. Mount the platform, close and latch the gate, and
attach approved fall restraint to designated platform
anchorage point. Attach only one fall restraint to
each point.
7. Without depressing the foot switch, move the drive
control handle, machine should not function.
8. Depress the foot switch and move the drive
control handle forward and reverse. Observe
that proportional functions operate smoothly, and
that brakes apply quickly after control is released.
9. While depressing foot switch, operate steer
switch to left and right. Observe that steering
wheels turn properly.
10.While depressing foot switch, turn function speed
control knob to desired setting, and operate
boom controls. Observe that boom operates
smoothly, and that upper boom, jib, turret rotation, platform level, and platform rotation controls
operate proportionally in conjunction with function speed control knob. Observe that platform
maintains level when boom is elevated.
11.With the upper boom elevated one foot, operate
drive control handle. Observe that drive speed is
limited to creep (1/2 foot [.15m] per second).
Lower upper boom to stowed position.
12.Press the service horn button. Observe that horn
is audible.

POSITIONING THE PLATFORM
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. 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.
5. Depress the foot switch and move the drive
control handle forward to travel forward and
reverse to travel in the reverse direction.
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.
With Boom Elevated
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.
Always, before operating any function, check the
area around and overhead for any obstructions or
electrical conductors.
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 functions will not operate while driving.
Lower Control Operation
All boom functions will operate at fixed speed.
1. Turn chassis keyswitch to chassis controls.
2. Operate boom control switches to position the
platform.
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.
