Levelling valve: the hydraulic system of the mobile column lift is designed to move
the master and slave columns in a synchronized way as a principle.
An accidental pressure loss in one of the lift cylinders or valves can bring the
master and slave columns out of synchronization, especially when a vehicle has
remained at height for a long time without engaging the safety locks.
The levelling valve enables the operator to bring the master and slave columns in
synchronization again. See section 9.8 on page 28.
6
Fail safety on the pallet jack mechanism: before lifting a vehicle, the operator
must lower the lift columns to the ground by means of the pallet jack mechanism,
to guarantee sufficient stability. A fail safety will do this automatically if the operator
forgets to do so.
7
Fuses: the electric system is protected several fuses against short-circuits and
amperage peaks.

Decals [standard]. The mobile column lifts are supplied with a number of operation
decals, load diagrams and safety decals. These decals must be kept clean and
legible at all times, and replaced whenever required.
