Change Oil - Siemens Flender KMP Series Assembly And Operating Instructions Manual

10.7.2 Change oil

Note
Observe the separately attached operating instructions BA 7300 and the information in item 7.1.
• Drain the oil while the gear unit is still warm, i.e. immediately after stopping it.
WARNING
Serious personal injury can be caused by switched-on machine
Shut down the gear unit and the oil-supply system to perform maintenance and/or repair work or prior
to removing the safeguards. Secure the drive unit against accidental start-up. Attach a notice on the
start switch stating clearly that work is in progress on the gear unit.
NOTICE
Property damage
Damage to the gear unit possible from inadequate lubrication because of mixed oils.
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.
When changing to any different oil type, the gear unit must be flushed thoroughly using the new oil type.
Flushing is not necessary, if the new service oil is fully compatible with the old service oil in all respects.
Compatibility must be confirmed by the oil supplier. If there is a change to another oil grade or make,
Siemens recommends flushing out the gear unit with the new grade of service oil.
Note
When changing the oil, the housing and the oil-supply system (if present) must be cleaned thoroughly
from sludge, metal particles and oil residue by flushing it with oil. Use the same type of oil as is used
for normal operation. High-viscosity oils must be heated beforehand using suitable means. Ensure that
all residues have been removed before filling with fresh oil.
Note
In this regard, see Figure 10.
• Place suitable containers under the oil drain cocks of the gear unit housing and of the tilting pad thrust
bearing chamber.
• Unscrew the screw plugs of the oil drain cocks and allow the oil to drain into the container.
CAUTION
Risk of scalding
Risk of injury from escaping hot oil.
Wear suitable protection gloves, protection glasses and protection clothing.
Remove any spilled oil immediately using an oil binding agent.
Observe environmental protection regulations.
• If the oil-supply system is equipped with three-way cocks, the gear unit can be emptied through the
three-way cocks of the oil-supply system. The remaining residual oil must then be drained off through
the oil drain cocks on the gear unit (1, 2).
