Introduction

This manual covers the operation of electric pow-

ered 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

discrepancies:
1. Open panels and check hydraulic components /

hoses for damage or leaks. Check electrical

components / wiring for damage or loose connec-

tions.

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 75 psi.

4. Check all hoses / cables for wear.
5. Inspect elevating assembly for damage, deforma-

tion, 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 mainte-

nance, page 9).

DO NOT use a machine that is damaged or

malfunctioning. Tag and remove the unit

from service until it is repaired.

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. 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 opera-

tion 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 rota-

tion, 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.
