7.7.2 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.
• Remove the housing cover over the stop bar for the trolley hoist on the
right-hand side of the machine.
• Undo the retaining screw and swivel out the electrical case (1).
• Check the oil level of the double screw drive at the expansion reservoir
(2) and replenish with oil if necessary.
• To do so, unscrew the cover 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 filling to take
place outside the machine housing.
• After replenishing the oil, replace the expansion reservoir in its bracket
and check filling level.
• Check whether oil is present in coiled relief hose (3) for the seals of the
double screw drive shafts. 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.
• Attach the electrical case and re-fit the housing cover.
Warning!
Inform VEMAG Customer Service immediately if there is oil in the relief
hose. The seals of the double screw drive must be replaced before
production is resumed.
