GENERAL SAFETY MEASURES
•Do not work under the vehicle when it is standing on jacks.
•Always ensure that the vehicle is blocked and unable to move before operating the hydraulic
levelling system.
•If present, shut off the air suspension system, but do ensure that air remains in the bellows
to prevent damage. Take measures to ensure that the pressure does not automatically adjust
during levelling.
•Wear safety glasses during installation and checking of the system.
•Prevent body parts (such as eyes and hands) from coming into contact with the released
fluids. The oil in the levelling system can be under high pressure, possibly causing serious
injuries to the skin. Immediately consult a doctor in the case of an accident.
•Never carry out repairs yourself in the event of malfunctions and/or repairs to the hydraulic
levelling system.
PRECAUTIONS BEFORE DRIVING
Every time before the vehicle is moved, visually inspect if the jacks are completely retracted. If this is
not the case, please follow the jack retraction procedure.
Do not exclusively rely on the system. The driver always remains responsible
and must check that all jacks are retracted before driving away.

LEVELLING SAFETY MEASURES
•Park the vehicle on a surface that is as flat as possible.
•Check if the surface on which the jacks will rest is preferably flat, not slippery, and free of
debris, rocks, etc.
•When parking on a soft surface, plates or blocks must be used under the bases of the
jacks, to prevent the supports sinking into the ground.
•The handbrake must be engaged before the system can be operated. Without an
engaged handbrake, the system will not function.
•The gear must be set to neutral or park.
•Ensure that the system has enough voltage. if necessary, start the vehicle during leveling
if the voltage is insufficient.
•Maintain distance from the vehicle, slide-outs, awnings, doors, steps, etc. The vehicle can
move in all directions when deploying or retracting the jacks.
•In order to achieve the most accurate result possible, it is advised to operate the system
from outside the vehicle or otherwise avoid moving when inside the vehicle.
•Press the STOP button on the control panel at any time if the operation must be
interrupted.
•If the operation has been interrupted, all jacks must be retracted. After that, you can
start over.
•ALWAYS check if all jacks are resting properly on the ground.
•Disengage the vehicle's ignition when the system is ready.
•NEVER MOVE THE VEHICLE WHEN ONE OR MORE JACKS ARE DEPLOYED.
