Preventive maintenance

Preventive maintenance work must be
carried out at regular intervals.
Make sure:
• that there is no abnormal noise or
vibrations
• that air oil cooler is securely fixed
• that the cooler matrix is clean -
debris will reduce the cooling
capacity
• that the air oil cooler is free from
damage, replace damaged
components
• that the air oil cooler is free from
leaks
• that warning labels are in good
condition, replace any damaged/
missing label immediately.
Annually: Check the electrical installa-
tion. This may only be made by a
qualified electrician.
Cleaning
Danger
Risk of bodily injury. Prior to
cleaning, disconnect all motor
power supplies.
Note! The air oil cooler might be hot.
Air oil cooler
When cleaning the exterior of the cooler,
for instance using water, disconnect all
power supplies. Be aware of the electric
motor protection standard.
Cooler matrix
The air fins of the matrix can be cleaned
by blowing through with compressed air.
If necessary a high-pressure washing
system and degreasing agent can be
used. When using a high-pressure
washing system point the jet parallel to
the air fins. See Figure 11.
Fan housing
Remove the cooler matrix when cleaning
the inside of the fan housing.
To clean the inside of the fan housing,
use compressed air. If necessary a
degreasing agent can be used.
Blow with compressed air from the
electric motor side through the fan
guard.
