Checking Tire Pressure
WARNING
Maximum tire pressure under any circumstances is 30 psi. Equal tire
pressure should be maintained at all times.
The rear tires on your unit may be over-inflated for shipping purposes.
Reduce the tire pressure before operating the mower. Recommended
operating tire pressure is approximately 20 p.s.i. Check the sidewall of
tire for maximum p.s.i.
Gas and Oil
The fuel tank has a capacity of two gallons. Remove the fuel cap by
turning it counterclockwise. Use only clean, fresh (no more than 30
days old), unleaded gasoline. Fill the tank no higher than four inches
below the top of the filler neck to allow space for fuel expansion.
WARNING
Use extreme care when handling gasoline. Gasoline is extremely
flammable and the vapors are explosive. Never fuel the machine
indoors or while the engine is hot or running. Extinguish cigarettes,
cigars, pipes and other sources of ignition.
NOTE: Your lawn mower is shipped with oil in the engine. However,
you MUST check the oil level before operating. Refer to the Service
and Maintenance Section for Check Oil instructions.
CAUTION
Always check the engine oil level before each use. Add oil as neces-
sary. Failure to do so may result in serious damage to your engine.
