If several jacks/roller carriages are used simultaneously, the load should be distributed
as evenly as possible over all jacks/roller carriages.
The following points must be observed while setting up jacks:
- Non-slip, flat ground so that the entire base of the jack rests on the ground. If there is
doubt concerning the load bearing capability of the ground, use suitable wooden or metal
base supports in order to increase the contact area.
CAUTION!
Hydraulic fluid can leave an oily film on the ground!
- The ground must provide support over the entire area (no grids, rubble, etc.)
- Never place jacks on ductile (non-rigid) base

In the majority of cases it is not possible to rest the load over the entire surface of the
jack piston. We therefore recommend using suitable piston guard plates otherwise the
piston rod or jack may be damaged. A convex piston guard plate evenly distributes the
load over the surface of the piston.
