9.5  Cleaning
Keep the motor as clean as possible since this is a decisive factor for 
correct operation. Regularly inspect the motor and motor compartment 
for build-up of dust, oil and other contaminants.
Dirty and/or greasy components should be cleaned with a rag 
moistened with solvent. Use a rag of lint-free cloth material. Do not use 
too much solvent as it could penetrate into the motor parts.
After cleaning, dry the components thoroughly. The easiest way is by 
heating. 
Note:
Windings and insulation must not be heated over 125°C and not for 
longer than 6 hours.
