G TROUBLESHOOTING
1. Most common causes of problems with the tipping cylinder
PHENOMENON POSSIBLE CAUSE SOLUTION
Body does not move
upwards Defect on the lorry Check that everything in the lorry is
being operated correctly, if there is
sufficient pneumatic pressure, etc.
Hydraulic pump supplies no oil Disassemble the hydraulic
compressed air hose and check that
oil circulates
Too little oil in the tank Top up the oil in the tank to
approximately 5 cm below the filler
cap
Kinks in oil lines Make sure there are no kinks in the oil
lines
Poorly screwed on quick-release
coupling Correctly screw on quick-release
coupling.
Defective quick-release coupling Check and/or replace quick-release
coupling.
The body does not tip
evenly There is air in the hydraulic
system Vent: see § E.3 – Venting the
hydraulic cylinder
Check the oil level in the tank
The hydraulic pump works
intermittently Replace the pump
The body does not fully tip Insufficient oil in hydraulic tank Check the oil level and top up if
required.
Overloading or unevenly
distributed load. The pressure
relief valve has opened or the
pump is not powerful enough to tip Evenly distribute the load or remove a
part of the load in another way
The body will not lower With an EDBRO cylinder: Increase engine speed until the
pressure relief valve opens
(screeching noise). Allow the engine
to run for 5 seconds then allow the
body to lower
The body does not remain
in the tipped position. With an EDBRO cylinder: Increase engine speed until the
pressure relief valve opens
(screeching noise). Allow the engine
to run for 5 seconds then allow the
body to lower
Cylinder tips too slowly Defective pump Replace pump
Viscosity of the oil too high
(unsuitable oil at a “low”
temperature)
Use the right hydraulic oil.
Excessive noise Low oil level Check the oil level and top up if
required
Obstructions and leaks Check lines for kinks and leaks.
2. Most common causes of problem with the roof sheet, type
“Cramaro”
PHENOMENON POSSIBLE CAUSE SOLUTION
When operating the selector
switch the roof sheet does not
move and the indicator light is
not on. Emergency stop pressed. Reset the emergency button
with the key.
Fuse (80A) blown. Check fusing and replace if
necessary.
Interrupted power or switched
off motor. Check the electrical installation.
Check that there are no broken
or disconnected cables.
Slow movement of the roof
sheet. Mechanical problem. Check whether the rear
bearings or discs are running
smoothly or are blocked.
Replace these components if
necessary.
Deformed roofing sheet arches. Check whether the roofing
sheet arches are distorted and
correct if necessary.
Metal tensioning cables too
tight. Loosen the metal tensioning
cables with the tensioning
device.
Metal tensioning cables slip
over the discs. Check whether the discs and
tensioning cables are
lubricated. Clean if necessary.
3. Most common causes of problems with the “bodyguard”
PHENOMENON POSSIBLE CAUSE SOLUTION
Ignition on, tipping body
resting on the chassis, control
light flashes Soiled proximity switch Clean proximity switch
Cables damaged Check cabling, and replace
cables if necessary
Damaged proximity switch Replace the proximity switch if
necessary, then try to establish
the cause of the damage.
The warning system does not
work when the ignition is
switched on. Light broken Replace light
Cables damaged Check cabling, and replace
cables if necessary.
No power on the bodyguard Investigate the cause of the
absence of power. Cable
breakage, blown safety fuse,
etc.
