COOLING SYSTEM CLEANING
At least once a year, or more often under adverse condi-
tions the cooling system should be cleaned. Cleaning
will assure an adequate supply of air to the cooling fins.
Compressed air may be used for routine cooling system
maintenance (Ref. Fig. 16).
Operation in wet or damp weather or overly fresh cut
grass may result in a variety of debris accumulating and
adhering to the internal shroud and fins of the cooling
system.
