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.
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 50 operating hours or monthly, whichever
occurs first (Fig. 27). Check the tires when they are
cold to get the most accurate pressure reading.
Pressure: 15 psi (.103 kPa) rear and castor tires
