DAILY SERVICE CHECKS
The following Maintenance Procedures should be
performed daily before operation.
Verify that all decals are correctly applied and in
plain view.
Refer to Section 5 for decal locations.
Verify that all controls and indicators at ground
and platform control stations operate properly.
Lower outriggers to level the boom lift.
Raise and extend all booms.
Press emergency STOP button.
Verify that booms remain elevated and do not drift.
Pull out STOP button and lower the booms.
If either control station is unresponsive, refer to Table
4-1 for troubleshooting procedures.
If display panel displays an error code, refer to Table
4-2 for error code definitions.
Verify that boom down limit switches operate
correctly.
Down limit switches are actuated when the boom is in
a fully lowered, stowed position. Limit switches must
be operational to raise or lower outriggers.
If outrigger controls are unresponsive when boom is
fully lowered and stowed, inspect down limit switches
for loose mounting or visible damage.
Repair or replace as needed.
Verify that outrigger safety interlocks operate
correctly.
Begin with the outriggers fully extended and the boom
lift level. Raise one outrigger until the footpad is not in
contact with the ground.
Verify that boom functions are unresponsive when
one outrigger is raised.
26
Repeat this procedure for each outrigger.
Raise all outriggers until the footpads are not in
contact with the ground. Verify that all outrigger status
LEDs on the ground control panel are unlit.
Lower one outrigger until the footpad makes contact
with the ground and the outrigger begins lifting the
trailer.
If the LED is lit before the footpad makes contact with
the ground or if the LED remains unlit after the weight
is transferred to the outrigger, the position switch or
wiring is faulty.
Repeat this procedure for each outrigger.
Repair or replace as needed. Refer to Figure 4-1.
Verify correct tire inflation.
In cold climates, inflate tires to 55 psi.
Figure 4-1. Outrigger Position Switches
Verify operation of running and brake lights.
Inspect hydraulic system and fluid levels.
Check all hydraulic hoses and fittings for leaks and
damage. Tighten or replace as necessary to prevent
hydraulic oil or pressure loss.
The hydraulic oil level should be checked with the
booms down, all outriggers raised and the trailer
wheels on a level surface.
Hydraulic oil should be visible in the sight gauge.
If the hydraulic oil level is not visible to at least half
way up the sight gauge (Figure 4-2), add clean
hydraulic fluid as necessary while all booms and
outriggers are fully retracted and stowed. Pour slowly
to avoid creating air pockets in the reservoir.
CAUTION
Do not mix hydraulic oils. Do not add any fluid to
the hydraulic system that is not expressly
recommended by the manufacturer. Adding
unauthorized fluids to the hydraulic system may
cause damage to equipment
The hydraulic reservoir is originally filled with Dexron
III/Mercon ATF with a viscosity rating of 175.
Manufacturer recommends a higher viscosity
hydraulic oil when operating equipment routinely in
extreme climates.
