securely fastened to the mower.
13. Carefully connect the fuel hose. Make sure the hose is
not kinked.
14. Slowly open the fuel valve to equalize the pressure in
the tank. If the fuel valve is opened too quickly, the
pressure relief valve is equipped with a back pressure
check valve that will shut off the fuel supply. If this
happens, close the fuel valve completely and wait five
seconds. Slowly open the fuel valve.
15. Check for leaks as described in the Inspection section.

Checking the Engine Oil Level

Before you start the engine and use the machine, check the oil
level in the engine crankcase; refer to Checking the Engine
Oil Level.

Breaking In a New Machine

New engines take time to develop full power. Mower decks
and drive systems have higher friction when new, placing
additional load on the engine. Allow 40 to 50 hours of
break-in time for new machines to develop full power and
best performance.
