Clean Fan And Gear Unit; Check Cooling Coil - Siemens FLENDER H SH Series Assembly And Operating Instructions Manual

10.2.2 Change oil
As an alternative to the oil­change intervals indicated in Table 29 (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.
• The instructions in item 7.1 must be observed!
• Close the stop valves in the coolant in­ and outflow pipes (gear units with cooling coil or water oil­cooling
system).
• 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 air filter including reducing screw at the housing top.
• Unscrew the oil­drain plug or 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 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 air filter (see item 10.2.3).
• Screw in the air filter including reducing screw.
• Fill fresh oil into the gear unit (see item 7.1.2).
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 benzine or a similar cleanser.
• 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.
