BLOWER 3.4
The blower inlet screen should be inspected periodically,
as noted in Section 15.1, for an accumulation of dirt
which, after prolonged operation, may affect the air flow.
Servicing of the screen consists of thoroughly washing it
in fuel oil and cleaning with a stiff brush until the screen
is free of all the dirt deposits.

1. Drain the cooling system.
