8.3.4 Cleaning the fan and gear unit
Introduction
The gear unit can sustain damage due to inadequate cooling if you operate it with a damaged
or soiled fan. Depending on the conditions at the site of installation, it may therefore be
necessary to clean the fan and gear unit more frequently than stipulated in the maintenance
schedule.
Procedure
Proceed as follows to clean the fan and gear unit:
1. Remove the air guide cover.
2. Use a hard brush to remove any stubborn dirt from the impeller, air guide cover and
protective grille. Never use a high-pressure cleaning device.
3. Treat any areas of corrosion.
4. Reinstall the air guide cover.
5. Make sure that the air guide cover is correctly fastened.
Make sure that there is no contact between the fan and the air guide cover.
8.3.5 Checking the cooling coil
Introduction
A soiled cooling coil can cause damage to the gear unit. It is therefore important to check the
cooling coil regularly.
Procedure
To check the cooling coil, proceed as follows:
1. Shut off the cooling water supply.
2. Disconnect the cooling water inlet and drain lines from the cooling coil.
3. Inspect the inner surface of the cooling coil for deposits.
