The hydraulic oil container is designed to hold a maximum
of 6.0 litres.
The oil level and condition of the hydraulic oil must
be checked at regular intervals (depending on the
level of use, but at least every 6 months)!
Only hydraulic oils of the HLP-B series
(ISO VG-46) may be used.
 Open the cover / oil filler spigot (Fig. 18 /1).
 Pour the respective hydraulic oil into the hydraulic oil
container (Fig. 18 /3).

Pay attention to the fill level marks (Fig. 18 /2).
 Have the hydraulic oil changed in a specialist workshop
if required.
Checking the supply battery

1 Rubber fasteners, secured (2x)
– The supply battery supplies the electro-hydraulic
equipment with a voltage of 12 V.
– Supply batteries in the form of gel or AGM batteries in a
gas-tight design (no screw caps on the top) are
maintenance-free according to DIN.
– Supply batteries in the form of fluid batteries with screw
caps on top must be serviced at regular intervals, in
order to maintain the charge capacity.
The installation date label (under the supply battery cover)
reveals the age of the supply battery.
 Replace defective or old supply batteries (Fig. 21 /6).
 Prevent possible battery damage e.g. lack of charge,
exhaustive discharge.

Check the power of the supply battery at regular intervals
(note the installation date label).
