Upright AB-46 I/C Manual Del Operador página 3

Introduction
This manual covers the operation of internal combustion
powered models of the AB-46 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 65 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 9).
9. Check fuel level, add fuel if necessary (see Fueling ,
page 9).
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
and hold the choke button while starting gasoline /
propane models; press the glow plug 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 proportional
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 proportionally 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 (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.
