Cleaning Engine Cooling
Systems
Before each use, check and clean cooling screen.
Remove any build–up of grass, dirt or other debris
from the engine air intake. Every 100 hours clean
engine cylinder and cylinder head cooling fins. Also
clean around carburetor, governor levers and linkage.
This will help insure adequate cooling to engine and
will reduce the possibility of overheating and
mechanical damage.
1. Clean off engine air intake (Fig. 28).
2. Blow out fins of engine and screen with
compressed air. If area between screen and fins is
tightly packed, remove engine shroud.
