Change Oil - Siemens FLENDER B3 E Series Assembly And Operating Instructions Manual

10.2.2 Change oil

As an alternative to the oil­change intervals indicated in table 19 (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.
Stop the gear unit by switching off the drive unit (see item 7.3).
Place a suitable container under the oil­draining point of the gear­unit housing.
Unscrew the air filter including reducing screw at the housing top.
Unscrew the oil­drain plug or the 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 safety gloves and safety glasses!
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.
Clean the permanent magnet of the oil­drain plug thoroughly.
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 air filter (see item 10.2.4).
Screw in the air filter including reducing screw.
Fill fresh oil into the gear unit (see item 7.1.2).
Gear unit with backstop and/or auxiliary drive:
Loosen residual oil­drain plug (pos. 4, figure 61) and drain off the oil into a vessel. Clean the oil­drain plug
thoroughly and screw in place (see item 7.1.1).
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.
When filling the main gear unit with oil (see item 7.1.2), start by the supplying
lubricating points (5, figure 61) with the oil quantity and oil grade specified on the
additional plates.
