Cleaning the Cooling System
Service Interval/Specification
Before each use, check and clean engine cooling system.
Remove any build–up of grass, dirt or other debris from
the cylinder and cylinder head cooling fins, air intake
screen on flywheel end, and carburetor–governor levers
and linkage. This will help insure adequate cooling and
correct engine speed and will reduce the possibility of
overheating and mechanical damage to the engine.
Checking the Tire Pressure
Service Interval/Specification
Maintain the air pressure in the front and rear tires as
specified. Check the pressure at the valve stem after every
40 operating hours or monthly, whichever occurs first
(Fig. 42). Check the tires when they are cold to get the
most accurate pressure reading.
Rear Tire Pressure: 12–14 psi (83–97 kPa)
Caster Tire Pressure: 25–30 psi (172–207 kPa)
