Recognising damaging condensate
Machines of this type are generally only lightly utilized. Condensate can build up in lightly utilized
machines with detrimental effects to the cooling oil and the machine itself. You can determine if your
machine falls into this category by regular sampling of the cooling oil during the first week of operation.
➤ Make sure you are familiar with the procedure before draining off any oil.
➤ A small quantity of cooling oil should be drained out to check for condensate at least once a week
during the first 4 weeks of operation.

Further information Information on draining off cooling oil is given in chapter 10.14.
