Service and Repairs
Cooling System
To ensure proper engine cooling, make sure the rotating
screen, cooling fins and other external surfaces of the
engine are kept clean at all times.
IMPORTANT: The engine that powers the Greens
Aerator is air–cooled. Operating the engine with
dirty or plugged cooling fins, a blocked rotating
screen or a plugged or dirty blower housing will re-
sult in engine overheating and engine damage.
1. Park machine on a level surface, fully raise coring
head, stop engine and remove key from the ignition
switch.
2. Raise lock–up brackets on each side of machine and
lower coring head until it rests on brackets.
IMPORTANT: Never clean engine with pressurized
water. Water could enter and contaminate the fuel
system.
3. Clean cooling fins on both cylinder heads.
4. Clean rotating screen and blower housing of dirt and
debris (Fig. 1).
IMPORTANT: Never operate engine without the
blower housing installed. Overheating and engine
damage will result.
5. Make sure rotating screen and blower housing are
reinstalled to the engine if removed.
NOTE: For additional information regarding the engine
cooling system, refer to the engine service manual at
the end of this chapter.
