BEFORE STARTING THE ENGINE
How To Prepare The Engine
WARNING: Always use a safety
fuel container. Do not smoke
when adding the fuel mixture to
the engine. When inside an enclosure,
do not fill the fuel tank. Before you add
the fuel mixture, stop the engine. Let the
engine cool for several minutes.
How To Mix The Fuel Mixture
The two cycle engine, used on this cultivator,
requires a mixture of gasoline and oil for lu-
brication of the bearings and other moving
parts. The correct fuel mixture ratio is 24:1
(5.3 oz. oil per one gallon of gas − see the
Fuel Mixture Chart). Gasoline and oil must
be pre−mixed in a clean gasoline container.
Always use fresh, clean, unleaded gasoline.
Mix gasoline and oil as follows:
1. Pour one (1) U.S. quart of fresh, clean,
unleaded automotive gasoline into a one
gallon size gasoline container.
2. Add 5.3 ounces of clean, high quality,
two−cycle oil to the gasoline container.
IMPORTANT: Do not use outboard mo-
tor oil or multi−viscosity oils,such as
10W−30 or 10W−40.
3. Install the fuel cap onto the gasoline con-
tainer. Vigorously shake the gasoline
container to mix the oil with the gasoline.
4. Add an additional three (3) U.S. quarts of
gasoline to the gallon container. Again
shake the gasoline container.
5. This completes the gasoline mixing pro-
cedure. The gasoline can now be added
to the fuel tank.

CAUTION: Gasoline is flam-
mable and caution must be used
when handling or storing it. Do
not fill fuel tank while cultivator is run-
ning, hot, or when cultivator is in an en-
closed area. Keep away from open
flame, electrical spark, and do not
smoke while mixing fuel or filling the
fuel tank. Never fill fuel tank completely;
but fill the tank to within 1/2 inch from
the top to provide space for expansion
of fuel. Always fill fuel tank outdoors
and use a funnel or spout to prevent
spilling. Make sure to wipe up any
spilled fuel before starting engine.
CAUTION: Experience indicates that alco-
hol blended fuels (called gasohol, 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 prob-
lems, the fuel system should be emptied
before storage for 30 days or longer.
Drain the gas tank, start the engine and
let it run until the fuel lines and carbure-
tor are empty. Use fresh fuel next season.
See Storage Instructions for additional
information. Never use engine or carbure-
tor cleaner products in the fuel tank or
permanent damage can occur.
Do not fill the fuel tank with gasoline that does not have oil mixed in it. Shake the
gasoline container before each filling of the fuel tank.
