10.2.2
Change oil
As an alternative to the oilchange intervals indicated in Table 13 (see item 10.1) it is possible to have the
oil sample tested at regular intervals by the Technical Service of the relevant oil company and to have it
released for further use.
If reusability has been confirmed, no oil change will be necessary.
Please observe the separately attached operating instructions BA 7300 EN.
•
The instructions in item 7.1 must be observed!
•
Drain the oil while the gear unit is still warm, i.e. immediately after shutting down the machinery.
When changing the oil, always refill the gear unit with the same type of oil. Never mix
different types of oil and/or oils made by different manufacturers. Never mix synthetic
oils with mineralbased oils or with other synthetic oils. When changing to any
different oil type, the gear unit must be flushed thoroughly using the new oil type.
When changing the oil, the housing and the oilsupply system, if available, must be flushed with
oil to remove sludge, metal particles and oil residue. Use the same type of oil as is used for
normal operation. Highviscosity oils must be heated beforehand using suitable means.
Ensure that all residues have been removed before filling with fresh oil.
•
Place a suitable container under the oildraining point of the gearunit housing.
•
Unscrew the breather screw on the top of the housing.
•
Unscrew oildrain plug or open oildrain cock and drain the oil into the collecting container.
•
Drain the oil from the oilsupply system (see operating instructions to the oilsupply system).
There is a danger of scalding from the hot oil emerging from the housing.
Wear protective gloves!
Remove any oil spillage immediately with an oilbinding agent.
Check the condition of the sealing ring (the sealing ring is vulcanised onto the oildrain plug).
If necessary, use a new oildrain plug.
•
Screw in the oildrain plug or close oildrain cock.
•
Clean the oil filter in the oilcooling system (see operating instructions of the oilsupply system).
•
Clean the breather screw (see item 10.2.3).
•
Screw in the venting screw.
•
Fill fresh oil into the gear unit (see item 7.1.2).
10.2.3

If a layer of dust has built up, the breather screw must be cleaned, whether or not the minimum
period of 3 months has expired.
•
Unscrew breather screw.
•
Clean the breather screw using benzine or a similar cleanser.
•
Dry the breather screw and/or blow with compressed air.
Be especially careful when blowing with compressed air.
