NSPECTION
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 covers and check hydraulic components/
hoses for damage or leaks. Check electrical com-
ponents / 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 5.5 bar (80 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. Ensure that gate
operates freely and latches securely.
7. Check hydraulic fluid level with platform fully low-
ered.
8. Check battery fluid level (see Battery Mainte-
nance, page 2-8).
9. Check fuel level; add fuel if necessary (see Fuel-
ing, page 2-8).
10. Ensure that radiator is cold; check coolant level.
Add if necessary.
System Function Inspection
NOTE: Refer to figures 2-1 and 2-2 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 pull out
the emergency stop switches to the ON position
at the chassis control panel and at the platform
control panel.
3. Turn key switch on, and wait for glow plug light to
go off. When glow plug light goes off, start
engine.
4. Push in the chassis emergency stop button;
engine should stop. Repeat for platform emer-
gency 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 opera-
tion of the machine. All functions should operate
through full cycle smoothly.(Make sure that the
Boom Speed Control is not at zero).
6. Turn chassis key switch to PLATFORM.
7. Mount the platform, lower the bar, 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 func-
tion.
10. Depress the foot switch and move the drive con-
trol 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, riser, and boom extend operate
proportionally in conjunction with function speed
control knob. Observe that platform maintains
level when boom is elevated.
