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.
NOTE: Perform this maintenance procedure at the in-
terval specified in the Operator's Manual.
IMPORTANT: The engine that powers Sand Pro and
Infield Pro machines is air–cooled. Operating the
engine with dirty or plugged cooling fins, a blocked
rotating screen or a plugged or dirty blower housing
will result in engine overheating and engine dam-
age.
1. Park machine on a level surface, lower attachment,
stop engine, apply parking brake and remove key from
ignition switch.
CAUTION
The engine and exhaust system may be hot. To
avoid possible burns, allow the engine and ex-
haust system to cool before working on the en-
gine.
IMPORTANT: Never clean engine with pressurized
water. Water could enter and contaminate the fuel
system.
2. Clean cooling fins on both cylinder heads.
3. Clean rotating screen and blower housing of dirt and
debris (Fig. 2).
4. If blower housing removal is necessary for cooling
system cleaning, engine needs to be removed from ma-
chine (see Engine Removal and Installation in this sec-
tion).
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.
