Introduction
This manual covers the operation of internal com-
bustion powered models of the SB60 Boom.
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 compo-
nents / 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 80 psi (5.5 bar)
4. Check all hoses / cables for wear.
5. Inspect elevating assembly for damage, defor-
mation, 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 fluid level in batteries (see battery main-
tenance, page 2-8).
9. Check fuel level, add fuel if necessary (see
fueling, page 2-8).
10.Check engine oil level.
11.Check air filter. Replace if necessary.
12.Set gasoline/propane selector to desired position.
Set to center position to purge the system when
switching fuels. If the machine is to be operated
on propane, open the supply valve on the tank.
NOTE: When using LP gas, use clean, water free
liquid petroleum gas, preferably from a bulk
storage tank.
NEVER remove the cap from a hot radiator.
Hot coolant can cause severe burns .
13.Ensure that radiator is cold, check coolant
level. Add if necessary.
2-2
If you smell propane, close the supply valve
on the tank immediately until you have
located and corrected the leak.
SYSTEM FUNCTION INSPECTION
Note: Refer to figures 2-2 through 2-5 for
chassis and platform control locations.
1. Before performing the following tests, check
area around machine and overhead for obstruc-
tions, 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 2-1.
4. Press the engine start button to crank the en-
gine; release when engine starts. If engine is
cold: press the glow plug button and hold for six
seconds prior to starting diesel models.
5. 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.
6. 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.
7. Turn chassis key switch to platform.
8. Mount the platform, and attach approved fall
restraint to designated 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.
