3.3 Mounting of Absorber, Spring Suspension and Double-acting Hydraulics

Generally
As standard the Front-Lift is equipped with single-acting hydraulics and not equipped with
absorber, spring suspension and double-acting hydraulics. These are available as accessories. HE-
VA supplies the accessories in sets, which are thus ready for mounting.
The purpose of the absorber (ST) is to absorb the hardest impacts when driving with lifted tools on
uneven surfaces. With double-acting hydraulics, the weight can be transferred from the tractor onto
the tool. In this connection we recommend that the Front-Lift is equipped with a spring suspension
system (AF), thus achieving a shock-absorbing connection with the tractor and the tool.

3.4 Mounting of Double-acting Hydraulics

When mounting double-acting hydraulics, the filter plugs are removed from the cylinders, and
fittings and hydraulic hoses are fitted. The cylinders are prepared for the double-acting system.

3.5 Mounting of Absorber (ST)

The accumulator (1 pc.) is fitted on the lifting side of the cylinders in accordance with the diagrams.

3.6 Mounting of Spring Suspension (AF)

The accumulators (2 pcs.) are fitted with 1 pc. on the lifting side and 1 pc. on the lowering side of
the cylinders in accordance with the diagrams
Before the hydraulic system is dismantled, the system must be
Important ! depressurised. Be especially careful if the Front-Lift is equipped
with accumulators (ST-AF).
When a dismantling of the hydraulic system is required, the Front-Lift must be totally lowered. Any
tools must be placed on a firm support. Stop the tractor and move the control handles of the Front-
Lift backwards and forwards until no more oil is flowing to back to the tractor.
After the mounting of accessories, the Front-Lift hydraulic
system must be flushed so that shavings from the used cutting

ring fittings are removed and will not cause any damage to the
tractor hydraulic system.
