CAUTION: Never take hold of moving parts.
11.1 Positioning of the hydraulic jack
• The contact surfaces of the load and of the hydraulic
jack must be cleaned before contact.
• The surface of the load which rests on the head or the
foot claw of the hydraulic jack should be level as far
as possible to ensure that the oil filler screw is exposed.
CAUTION: The load must never rest on the
oil filler screw!
• Make absolutely sure that the load contact surface is
appropriate for the load.
• The surface for the jack must be adequately firm
(stable), horizontal and non-slip; use underlays if
necessary.
• The jack is to be positioned so that there is no
necessity to reach under the suspended load.
• The load may only be lifted at the designated points of
the hydraulic jack (foot claw and head). The load
must always rest in the centre of the head or the foot
claw (Fig. 11.1.1).
• Never lift the load on one side of the head (Fig. 11.1.2).
Fig. 11.1.1
• For load resting on the claw the load must always
contact the shaft of the jack. If this is not possible,
the spacer block (supplied) must be used to minimise
the bending stress of the pillar (Fig. 11.1.3).

• The spacer block can be inserted in two different
positions.
• For correct use, insert the spacer block to the
hydraulic jack as in Fig. 11.1.3. The spacer block can
be used for two different spacing options. These are
labelled with arrows. Adjust the spacings by rotating
the spacer block. The arrow must be aligned vertically
to the load throughout. Remove the spacer block if it
is not required during the application because the load
is contacting the jack shaft.
• If the spacer block does not offer the correct spacing,
use another corresponding spacer block. The spacer
block must not necessarily be fixed to the hydraulic
jack but it is recommended. The material of the
spacer block must be able to withstand the forces
applied without deforming. The contact surface must
be level and flat.
CAUTION: No wedges to be used. With the
foot claw it must be ensured that the
minimum resting surface is met.
• The load must always cover at least the red marking
(corresponds to > 3 claw teeth).
• Vehicles or loads must be secured against rolling or
slipping away before lifting.
11.2 Lifting the load
• The release valve must be closed when lifting the
load. To do this, turn the release valve screw
clockwise. The direction is identified with the
following symbol:
• The load is lifted by moving the hand lever up and
down.
