Introduction
This manual covers the operation of internal combustion
powered models of the AB-46 RT Articulated Boom. This
manual must be stored on the machine at all times.
Pre-Operation and Safety
Inspection
Carefully read, understand and follow all safety rules,
labels, and operating instructions, then perform the
following steps each day before use.
Perform a complete visual inspection of the entire unit
prior to operating. Check the following areas for discrep-
ancies:
1. Open panels and check hydraulic components / hoses
for damage or leaks. Check electrical components /
wiring for damage or loose connections.
2. Inspect chassis, axles, hubs, and steering linkage for
damage, deformation, buckled paint, loose or missing
hardware, and cracked welds.
3. Check tires for damage, punctures, and inflation; tire
pressure must be 3,8 bar (55 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, deforma-
tion, 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 10).
9. Check fuel level, add fuel if necessary (see fueling,
page 10).
10. Ensure that radiator is cold, check coolant level. Add
if necessary.
NEVER remove the cap from a hot radiator. Hot
coolant can cause severe burns.
SYSTEM FUNCTION INSPECTION
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. Press the engine start button to crank the engine;
release when engine starts. If engine is cold: press
the preheat button and hold for six seconds prior to
starting diesel models.
4. Push in the chassis emergency stop button engine
should stop. Repeat for platform emergency stop
button. Return both emergency stop buttons to the
on position, and start engine.
5. 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.
6. Turn chassis key switch to platform.
7. 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.
8. Start the engine.
9. Without depressing the foot switch, move the drive
control handle, machine should not function.
10. Depress the foot switch and move the drive control
handle forward and reverse. Observe that propor-
tional functions operate smoothly, and that brakes
apply quickly after control is released.
11. While depressing foot switch, operate steer switch to
left and right. Observe that steering wheels turn
properly.
12. 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 propor-
tionally in conjunction with function speed control
knob. Observe that platform maintains level when
boom is elevated.
13. With the upper boom elevated one foot, operate
drive control handle. Observe that drive speed is
limited to creep approximately (1 foot [.3m] per
second). Lower upper boom to stowed position.
14. Press the service horn button. Observe that horn is
audible.
DO NOT use a machine that is damaged or
malfunctioning. Tag and remove the unit from
service until it is repaired.
