• Never operate the engine without heat shields
or guards.
IMPORTANT :
• The air intake area must be clear of debris to
prevent the engine from overheating.
Daily or after every 5 hours of operation, check to be
sure the radiator screen and the hood screen are clean.
Dirt or chaff on the radiator screen, hood screen or
radiator decrease cooling performance.
1. Remove the radiator screen and the hood screen,
and remove all foreign material.
2. Remove the dust from between the fins and the
tube.
3. Tighten the fan drive belt as necessary. Details
regarding this procedure can be found in a different
section.
(See Adjusting fan drive belt tension on page 71.)
4. If the scale forms in the tube, clean with the scale
inhibitor or its equivalent.
5. Each time the hood screen is covered with grass
during operation, rub it off the screen with the hand.
Check the radiator screen from time to time if grass
accumulates.
6. If the dust or chaff has accumulated inside of the
hood, remove the radiator screen and clean inside
completely.
After cleaning, replace the radiator screens
properly.
7. Check the radiator for dust or chaff build up.
If the dust or chaff has accumulated in the radiator,
clear with air pressure (not to exceed 30 psi) or a
hose.

6. Checking the tire pressure
WARNING
To avoid serious injury or death:
• Do not attempt to mount a tire on a rim. This
should be done by a qualified person with the
proper equipment.
• Always maintain the correct tire pressure.
The inflation pressure in the front tires rises
quickly when using compressed air.
Do not inflate the tires above the recommended
pressure shown in the operator's manual.
IMPORTANT :
• Do not use tires larger than specified.
6.1 Inflation pressure
Even though the inflation pressure is factory-set to the
prescribed level, it naturally drops slowly in the course
of time. Therefore, check it everyday and inflate as
necessary.
