Clean The Air Filter - Siemens FLENDER GHZP Assembly And Operating Instructions Manual

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. Polyglycol­based
synthetic oils in particular must not be mixed with PAO­based synthetic oils or mineral
oils. If changing to a different grade or make of oil, the gear unit must, if necessary, be
flushed out with the new oil grade. 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.
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 air filter on the top of the housing.
• Unscrew the oil­drain plug and/or the open the 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!
Any oil spillage must be removed 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.
• Close the oil­drain cock and/or screw in the oil­drain plug.
• Clean the oil filter in the oil­cooling system (see operating instructions to the oil­supply system).
• Clean the air filter (see item 10.2.3).
• Screw in the air filter again.
• Fill fresh oil into the gear unit (see item 7.1.3).

10.2.3 Clean the air filter

If a layer of dust has built up, the air filter must be cleaned, whether or not the minimum period
of 3 months has expired.
• Unscrew the air filter including the reducing screw.
• Clean the air filter using a suitable cleaning agent.
• Dry the air filter and/or blow with compressed air.
Be especially careful when blowing with compressed air.
Wear protective glasses!
Foreign bodies must be prevented from entering the gear unit.
