ON/OFF SWITCH
The ON/OFF SWITCH is used to stop the en-
gine. To stop engine, move switch to OFF.
CHOKE
The CHOKE helps to supply fuel to the engine
to aid in cold starting. Activate the choke by
moving choke lever to the desired position. See
STARTING YOUR ENGINE for complete start-
ing information.
PRIMER BULB
The PRIMER BULB removes air from the car-
buretor and fuel lines and fills them with fuel.
This allows you to start the engine with fewer
pulls on the starter rope. Activate the primer
bulb by pressing it and allowing it to return to
its original position.
THROTTLE TRIGGER
The THROTTLE TRIGGER controls engine
speed. Squeeze the trigger for full speed opera-
tion; release it for idle speed.
WARNING: Muffler is very hot during
and after use. Do not touch the muffler or al-
low combustible material such as dry grass or
fuel to do so.
BEFORE STARTING ENGINE
WARNING: Be sure to read the fuel
information in the safety rules before you be-
gin. If you do not understand the safety rules,
do not attempt to fuel your unit. Call
1-800-235-5878.
FUELING ENGINE
WARNING: Remove fuel cap slowly
when refueling.
This engine is certified to operate on unleaded
gasoline. Before operation, gasoline must be
mixed with a good quality synthetic 2-cycle air-
cooled engine oil designed to be mixed at a ratio
of 40:1. Mix gasoline and oil at a ratio of 40:1. A
40:1 ratio is obtained by mixing 3.2 ounces (95
ml) of oil with 1 gallon (4 liters) of unleaded gaso-
line. DO NOT USE automotive oil or boat oil.
These oils will cause engine damage. When
mixing fuel, follow instructions printed on con-
tainer. Once oil is added to gasoline, shake con-
tainer momentarily to assure that the fuel is thor-
oughly mixed. Always read and follow the safety
rules relating to fuel before fueling your unit.
IMPORTANT
Experience indicates that alcohol blended fuels
(called gasohol or using ethanol or methanol)
can attract moisture which leads to separation
and formation of acids during storage. Acidic
gas can damage the fuel system of an engine
while in storage. To avoid engine problems,
empty the fuel system before storage for 30
days or longer. Drain the gas tank, start the en-
gine and let it run until the fuel lines and carbure-
tor are empty. Use fresh fuel next season. Nev-
er use engine or carburetor cleaner products in
the fuel tank or permanent damage may occur.
