ENGINE SAFETY PRECAUTIONS
Warning Carbon Monoxide Poisoning
All engine exhaust contains carbon monoxide.
Carbon monoxide is a deadly, colorless, tasteless,
odorless gas which may be present even if you do
not smell or see engine exhaust. Levels of carbon
monoxide, which can be deadly, can be present for
days in an enclosed area that has poor ventilation.
Any level of carbon monoxide, if inhaled, can cause
headaches, drowsiness, nausea, dizziness, confusion
and eventually death. If you experience any of these
symptoms, seek fresh air and medical attention
immediately.
Preventing Carbon Monoxide Poisoning
• Never run engine indoors or in a conned area.
• 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 removed. (Examples include large holes
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 muer
pointed away from the operator.
• Never point the exhaust muer towards anyone.
Bystanders should always be many feet away from
the operation of the engine.
Gasoline Fires and Handling Fuel Safely
Fuel and fuel vapors are highly ammable. Never use
fuel where a spark or ame may be present. Never use
fuel where a potential source of ignition could occur.
(Examples include: hot water or space heaters, clothes
dryer, electric motors, etc.) Keep ames and sparks
away from engine and fuel to prevent res. Fuel res
spread very quickly and are highly explosive.
Prevention of Gasoline Fires
• Always ll fuel tank outside in a well ventilated area
with the engine stopped.
• 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 wipe up excess (spilled) fuel from engine
before starting. Clean up spilled fuel immediately.
• If fuel spillage occurs, wipe away carefully and allow
fuel to dry before starting the engine.
• 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 relling engine fuel tank.
• 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).
• Do not store engine with fuel in fuel tank indoors.
Fuel and fuel vapors are highly explosive.
• During storage, screw down gas cap vent screw
tightly.
• Never pour fuel from engine fuel tank.
• Never siphon fuel by mouth to drain fuel tank.
• Always have an adult ll the fuel tank.
• Never allow anyone under the inuence of drugs or
alcohol to ll engine.
• Never allow children to ll the fuel tank.

BURNS AND FIRES
The muer, muer guard and other parts of the
engine become extremely hot during the operation
of the engine. These parts remain extremely hot after
the engine has stopped.
This engine is designed to operate using a catalytic
converter which contributes to the engine’s
compliance with the EPA.
Prevention of Burns and Fires
• Never remove the muer guard from the engine.
• Never touch the muer guard because it is
extremely hot and will cause severe burns.
• Never touch parts of the engine that become hot
during and after operation.
• Always keep materials and debris away from
muer guard and other hot parts of the engine to
avoid res.
CAUTION
AVOID INJURY! WHEN WORKING ON OR
REPLACING PARTS FOR THE ENGINE OR PUMP
YOU MUST ALWAYS DISCONNECT SPARK PLUG
WIRE FROM THE SPARK PLUG AND KEEP IT
AWAY FROM THE SPARK PLUG.
3. Securely place the disconnected spark plug wire
away from the spark plug and any metal parts. This
must always be done or arcing may occur between
spark plug wire and metal parts.
4. Replace or repair the part on the engine or pump.
5. Check all parts that were repaired, or removed
during repair, that they are secure and t correctly.
NOTE: All repair parts must come from the factory.
Never replace parts that are not specically
designed for the pump.

stored briey with fuel in the tank, prime one time above
55° Fahrenheit or two times below 55° Fahrenheit.
Warm Start: Do not use primer or full choke if engine
did not run out of gas or has not cooled completely.
Flooding will occur.
6. CHOKE:
• Full choke position is dened by moving the
choke lever as far to the ON or CHOKE position as
possible. Half choke is dened when the choke
lever is between ON or CHOKE and OFF or RUN.

MAINTENANCE AND STORAGE
ENGINE MAINTENANCE
Please read the maintenance schedule and observe
these recommendations to extend the life of your
engine.
Good maintenance is essential for safe, economical,
and trouble-free operation. It will also help reduce air
pollution. To help you properly care for your engine,
the following pages include a maintenance schedule,
routine inspection procedures, and simple main-
tenance procedures using basic hand tools. Other
service tasks that are more difficult, or require special
tools, are best handled by professionals and are
normally performed by a technician or other qualified
mechanic.
Maintenance, replacement or repair of the emissions
control devices and systems may be performed by
any non-road engine repair establishment or individu-
als. However, items must be serviced by an authorized
dealer to obtain "no charge" emissions control service.
The maintenance schedule applies to normal operat-
ing conditions. If you operate your engine under
unusual conditions, such as sustained high-load or
high-temperature operation, or use in unusually wet
or dusty conditions, consult your servicing dealer for
recommendations applicable to your individual needs
and use.

the maintenance records should be transferred to each subsequent

als; however, warranty repairs must be performed by an Ardisam
authorized service center. Any replacement parts or service that is

the engine manufacturer.
