Engine Safety Precautions
If your product comes with a separate engine manual, be
sure to read and follow all safety and warning precautions
outlined there, in addition to any in this manual.
Preventing Carbon Monoxide Poisoning
• Always start and run engine outdoors. Do not start
or run engine in an enclosed area, even if doors or
windows are open.
• Never try to ventilate engine exhaust indoors. Carbon
monoxide can reach dangerous levels very quickly.
• Never run engine outdoors where exhaust fumes may
be pulled into a building.
• Never run engine outdoors in a poorly ventilated area
where the exhaust fumes may be trapped and not
easily taken away. (Examples include: in a large hole
or areas where hills surround your working area.)
• Never run engine in an enclosed or partially enclosed
area. (Examples include: buildings that are enclosed
on one or more sides, under tents, car ports or
basements.)
• Always run the engine with the exhaust and muer
pointed in the direction away from the operator.
• Never point the exhaust muer towards anyone.
People should always be many feet away from the
operation of the engine and its attachments.
• Do not change the engine governor settings or over-
speed the engine.
Gasoline Fires and Handling Fuel Safely
Use extra care in handling gasoline and other fuels. They are
ammable and vapors are explosive.
• When storing extra fuel be sure that it is in an
appropriate container and away from any re hazards.
• Prevent re and explosion caused by static electric
discharge. Use only nonmetal, portable fuel
containers approved by the Underwriter’s Laboratory
(U.L.) or the American Society for Testing & Materials
(ASTM).
• Never remove the fuel cap or add fuel with the engine
running. Stop engine and allow to cool before lling.
• Never drain fuel from engine in an enclosed area.
• Always ll fuel tank outside in a well ventilated area.
Never ll your fuel tank with fuel indoors. (Examples
include: basement, garage, barn, shed, house, porch,
etc.) Never ll tank near appliances with pilot lights,
heaters, or other ignition sources. If the fuel has to be
drained, this should be done outdoors. The drained
fuel should be stored in a container specically
designed for fuel storage or it should be disposed of
carefully.
• Always wipe up excess (spilled) fuel from engine
before starting. Clean up spilled fuel immediately.
If fuel is spilled, do not start the engine but move
product and fuel container from area. Clean up spilled
fuel and allow to evaporate and dry after wiping and
before starting.
• Allow fuel fumes/vapors to escape from the area
before starting engine.
• Test the fuel cap for proper installation before starting
and using engine.
• Always run the engine with fuel cap properly installed
on the engine.
• Never smoke while relling engine fuel tank.
• Do not store engine with fuel in fuel tank indoors. Fuel
and fuel vapors are highly explosive.
• Handle fuel with care; it is highly ammable.
a. Use an approved fuel container.
b. Never add fuel to a running engine or hot engine.
c. Fill fuel tank outdoors with extreme care. Never ll
fuel tank indoors.
d. Replace gasoline cap securely and clean up spilled
fuel before restarting.
Preparation
• Dress appropriately when operating the earth auger
powerhead. Always wear sturdy footwear. Never wear
sandals, sneakers or open shoes, and never operate
the auger with bare feet. Do not wear loose clothing
that might get caught in moving parts.

Transporting Your Earth Auger Powerhead
1. Never transport engine inside an enclosed space or
vehicle. Fuel or fuel vapors may ignite causing serious
injury or death.
2. If fuel is present in the fuel tank, transport in an open
vehicle in an upright position.
3. If an enclosed vehicle must be used, remove gas into an
approved red fuel container. DO NOT siphon by mouth.
4. Run engine to use up the fuel in the carburetor and fuel
tank. Always run engine in a well ventilated area.
5. Wipe away any spilled fuel from engine and earth auger
powerhead. Allow to dry.
6. Ensure gas cap is shut tightly before transporting
powerhead in a vehicle.
Long-Term Storage
If your powerhead will not be used for more than one month,
prepare it for long term storage.
Steps for Long-Term Storage
1. Mix an appropriate amount of fuel stabilizer to fresh
gasoline in the ratio recommended on the stabilizer
packaging. Run the engine for ve minutes to distribute
the stabilizer mixture throughout the fuel system. This
will prevent gum, varnish and corrosion build up in
your fuel system during long-term storage for up to 12
months.
2. Remove auger from powerhead and apply a thin layer of
grease to the output shaft of the transmission.
3. Store auger and powerhead in an upright position.
4. Remove all debris from auger and powerhead.
