Remedies
Add oil.
Check if, by activating the UP command, the solenoid valve
receives electricity and/or check the coil using the magnet
checking device .
Replace the coil or the valve if necessary.
Replace the pump.
Check the system's pressure and adjust the valve.
Charge the battery.
Check the single cells.
Check the power supply cable.
As an emergency solution, place the vehicle's engine in
motion. Install a more powerful alternator.
Replace the fuse.
Thoroughly clean the contact terminals.
Replace if necessary.
Thoroughly clean the contact terminals. Replace if neces-
sary.
Replace the fuse.
Repair the engine. Stop use of the platform, to avoid
damaging the electric motor.
Control power supply fuse has burned out .
Turn on the main switch, replace if necessary.
Replace the fuse.
Replace the fuse (10A 24V) – (15A 12V).

Replacement.
The engine is once again ready for use after it has cooled
down for about 5 minutes. Remove the cover of the
hydraulic unit to increase cooling.
