5. OPERATION INSTRUCTIONS
5.1 PRE-START
5.1.1 Fill fuel tank. For best results use only clean, fresh regular grade unleaded
gasoline with an octane rating of 87 or higher. Regular grade leaded gasoline
may also be used; however, combustion chamber and cylinder head will require
more frequent service. See Engine Owner's Manual.
Note: Fuel tank may appear loose at set-up, however, once fuel is added, tank
will slowly expand to fit tank straps.
Do not add oil to gasoline.
Never fill the fuel tank so that the fuel level rises above a level that is 1/2” below
the bottom of the filler neck to allow for fuel expansion and prevent fuel spillage.
5.1.2 Make sure you understand the controls, their locations, their functions, and their
safety requirements.
5.1.3 Refer to the Maintenance Section, and perform all of the necessary inspection
and maintenance steps.
5.2 MOWING
5.2.1 Starting Engine: Operator must be in the seat with the parking brake engaged
and the PTO disengaged.
Open fuel shut-off value.
On a cold engine, place the throttle midway between the "SLOW" and "FAST"
positions and place the choke in the "ON" position. On a warm engine, place the
throttle midway between the "SLOW" and "FAST" positions and leave the choke
in the "OFF" position.
Turn ignition switch to "START" position. Release the switch as soon as the
engine starts.
After starting a cold engine, gradually return choke to the "OFF" position after
engine warms up.
IMPORTANT: Do not crank the engine continuously for more than ten (10)
seconds at a time. If the engine does not start, allow a 60 second starter cool-
down period between starting attempts. Failure to follow these guidelines can
burn out the starter motor.
5.2.2 Stopping Engine: Bring unit to a full stop. Disengage the PTO and engage the
park brake.
Before stopping the engine, place the throttle control midway between the “slow”
and “fast” positions. Allow the engine to run a minimum of 15 seconds; then stop
the engine.
