Cleaning the Cooling Systems
Before each use, check and clean cooling screen.
Remove any build–up of grass, dirt or other debris
from the oil cooler screen and engine air intake.
Every 100 hours clean oil cooler, engine cylinder and
cylinder head cooling fins. Also clean around
carburetor, governor levers and linkage. This will
help insure adequate cooling to hydraulic pumps,
motors and engine and will reduce the possibility of
overheating and mechanical damage.

Tire Pressure
Maintain the air pressure in the front and rear tires as
specified. Uneven tire pressure can cause uneven cut.
Check the pressure at the valve stem after every 50
operating hours or monthly, whichever occurs first
(Fig. 33). Check the tires when they are cold to get
the most accurate pressure reading.
Pressure: 13 psi (90 kPa) drive wheels and castor
wheels.
