Introduction
This manual covers the operation of internal combustion
powered models of the SB-80 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 7 bar (100 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, defor-
mation, buckled paint, loose or missing hardware,
and cracked welds. Insure that gate operates freely.
7. Check Hydraulic fluid level with platform fully lowered.
8. Check fluid level in batteries (see Battery mainte-
nance, page 10).
9. Check fuel level, add fuel if necessary (see Fueling,
page 10).
10. Check engine oil level.
NEVER remove the cap from a hot radiator. Hot
coolant can cause severe burns.
11. Ensure that radiator is cold, check coolant level. Add
if necessary.
SYSTEM FUNCTION INSPECTION
Note: Refer to Figures 1 through 5 for chassis and
platform control locations.
IMPORTANT: Before performing the System Func-
tion Inspection be sure the axles are fully extended.
For axle extending instructions, refer to "Extending
and retracting Axles" (Page 6).
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
emergency stop switches at the chassis control
panel and at the platform control panel.
3. Retract locking bolt. See Figure 1.
4. Press the engine start button to crank the engine;
release when engine starts.
5. 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.
6. With axles fully extended, 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.
7. Turn chassis key switch to platform.
8. Mount the platform, and (If required by National
Legislation) attach approved fall restraint to desig-
nated platform anchorage point. Attach only one fall
restraint to each point.
9. While engaging the hand interlock, move the drive
control handle forward and reverse. Observe that
proportional functions operate smoothly, and that
brakes apply quickly after control is released.
10. While engaging the hand interlock, operate steer
switch to left and right. Observe that steering wheels
turn properly.
11. While depressing foot switch, operate boom con-
trols. Observe that boom operates smoothly, and
that boom raise and lower, turret rotation, and boom
extension and retraction operate proportionally in
conjunction with stroke of handle. Observe that
platform maintains level when boom is elevated.
