Checking the Tire Pressure

Service Interval: Every 50 hours/Monthly (whichever
comes first)
Maintain the air pressure in the rear tires at 83-97 kPa (12-14
psi). Uneven tire pressure can cause an uneven cut.
Note: The front tires are semi-pneumatic tires and do not
require air pressure maintenance.

Cleaning the Air Intake Screen

Before each use 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.

Cleaning the Cooling System

Service Interval: Every 100 hours/Yearly (whichever comes
first)
Clean the air intake screen from grass and debris before each
use.
