8.10.1 Double screw drive (oil change)
The oil in the double screw drive should be changed every two years.
• Open the service hatch on the right-hand side.
• Unscrew the cover (1) 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.
• Drain the used oil into a suitable container.
• Then ll the expansion reservoir with fresh oil and attach the expan-
sion reservoir back in its bracket after replenishing it. Check the lling
level. The oil should come at least to the marking on the reservoir.
• Check whether oil is present in coiled relief hose for the seals of the
double screw drive shafts. If this should be the case, the seals in the
double screw drive must be replaced, otherwise there is a risk of oil
getting into the double screws.

Warning!
Inform VEMAG Customer Service immediately if there is oil in the relief

duction is resumed.
