12 PUTTING THE LIFTGATE INTO SERVICE
• Switch on the battery switch. Use the functions “lift” and “tilt” to brig hydraulic pressure into the hydraulic circuits. Stop when you hear
the hydraulic pump turn in overpressure.
• Lower and remove the hydraulic mounting jack.
• Remove and installation hardware and the locking bolts on the swing
brackets of the mechanical tilt device [see Figure 12.1].
• Execute the lift and tilt functions at least 5 times so the hydraulic cylinders
can be purged completely.
• Only the sound of the pump unit should be audible. In case of jerking
movements or odd sounds, you should investigate and correct to avoid
damage to the liftgate or hazards to operators.
• Preferably, raise the rear end of the vehicle off the ground, or raise the vehicle air suspension to its maximum. Starting from the
platform in work position at the loading floor:
1. Open the platform completely (below horizontal position), until the cylinders are fully retracted, and continue to push the
function “open” for another 20 seconds [see Figure 12.2].
2. Tilt the platform back up to horizontal position, and lower the platform completely (further down below the normal ground level),
until the lift cylinders are fully retracted, and continue to push the function “lower” for another 20 seconds
[see Figure 12.2].
▪ Ensure that all electrical connections are correctly finished and that all mounting bolts are fastened with the
required torque.
▪ Consult the USER’S MANUAL in case of doubt with regards to the correct use of the different lift functions
and of the applicable safety instructions.
▪ Failure to do so could cause accidental fall of the liftgate and result in serious injury or death to the operator
and any bystanders.
