8.7 Monthly maintenance
8.7.1 Double screw drive (oil level and seals)
The oil expansion reservoir of the double screw drive and its cover are
attached in a bracket and connected to the double screw drive by a hose.
The oil should come up at least to the marking on the reservoir.
• Open the service hatch on the right-hand side.
• Check the oil level of the double screw drive at the expansion reser-
voir (1) and replenish with oil if necessary.
• To do so, unscrew the cover (2) of the expansion reservoir, holding the
reservoir steady in the other hand, and take it out of its bracket. You
must hold the reservoir upright so that no oil escapes. The connecting
hose to the double screw drive is long enough to enable lling to take
place outside the machine housing.
• After replenishing the oil, replace the expansion reservoir in its bracket
and check lling level.
• The machine is stopped if the leak detector sensor indicates leakage
into the doublescrew drive leak detection area. If this should be the
case, the seals of the double screw drive must be replaced, otherwise
there is a risk of oil getting into the double screws.
