Engine Operation
Before Starting the Engine
Check the Oil
NOTE: The engine was shipped from the factory filled with
oil. Check the level of the oil. Add oil as needed. See the
engine manufacturer’s instructions for the type of gasoline
and oil to use.
1. Make sure the unit is level.
NOTE: Do not check the level of the oil while the engine
runs.
2. Check the oil. Follow the procedure in the engine
manufacturer’s instructions.
3. If necessary, add oil until the oil reaches the FULL mark
on the dipstick. The quantity of oil needed from ADD to
FULL is shown on the dipstick. Do not add too much
oil.
Add Gasoline
WARNING: Always use a safety gasoline container.
Do not smoke when adding gasoline to the fuel tank.
Do not add gasoline when you are inside an
enclosure. Before you add gasoline, stop the engine
and let the engine cool for several minutes.
Fill the fuel tank with regular unleaded gasoline. Do not use
premium unleaded gasoline. Make sure the gasoline is fresh
and clean. Leaded gasoline will increase deposits and
shorten the life of the valves.

CAUTION: A mixture of alcohol (ethanol or methanol) and
gasoline (called gasohol), will attract moisture and cause
acid deposits during storage. While the unit is in storage, the
acids in the fuel can damage the fuel system.
To prevent engine problems with the fuel system, empty the
fuel system before storage of 30 days or longer as follows.
1. Drain the fuel tank.
2. Start the engine. Let the engine run until the fuel lines
and the carburetor are empty.
3. After storage, make sure you use fresh fuel. See the
storage instructions for additional information.
4. Never use engine cleaner or carburetor cleaner in the
fuel tank or permanent damage can occur.
Carburetor
Do not attempt to adjust the carburator. Engine adjustments
and repairs should be performed only by an authorized
dealer.
How to Start the Engine
WARNING: The electrical system has an operator
presence system that includes a sensor switch for
the seat. These components tell the electrical system
if the operator is sitting on the seat. This system will
stop the engine when the operator leaves the seat.
For your protection, always make sure this system
operates correctly.
NOTE: The engine will not start unless you depress the brake
pedal or engage the parking brake and disengage the blades.
1. Push the brake pedal completely forward. Keep your
foot on the pedal.
2. Make sure the blades are disengaged.
3. Move the throttle control completely forward to the
FAST position.
4. Move the choke control completely forward.
5. Turn the ignition key to the START position. Release
the key when the engine starts.
NOTE: If the engine does not start after four or five
tries, see the TROUBLESHOOTING CHART.
6. Turn off the choke, and slowly move the throttle control
to the SLOW position.
7. Let a cold engine run for several minutes. Begin work
when the engine is warm. To start a hot engine, move
the throttle control to a position between FAST and
SLOW.
