operate the engine to check its condition. Be sure to take care
before you operate the engine.
Before beginning your preoperation checks, be sure the engine is
level and the engine switch is in the OFF position.
CHECK THE GENERAL CONDITION OF THE ENGINE
Look around and underneath the engine for signs of oil or
gasoline leaks.
Remove any excessive dirt or debris, especially around the
Look for signs of damage.
Check that all shields and covers are in place, and all nuts, bolts,
and screws are tightened.
CHECK THE ENGINE
Check the engine oil level. Running the engine with a low oil level
can cause engine damage.
To avoid the inconvenience of an unexpected shutdown,
always check the engine oil level before startup.
Check the air Ćlter. A dirty air Ćlter will restrict air ćow to the
carburetor, reducing engine performance.
Check the fuel level. Starting with a full tank will help to eliminate
or reduce operating interruptions for refueling.

Very warm storage temperatures accelerate fuel
deterioration. Gasoline will oxidize and deteriorate
in storage. Deteriorated gasoline will cause hard
starting, and it leaves gum deposits that clog the
fuel system. As a result, If the engine is not used for
more than one month, the fuel oil shall be drained
thoroughly to prevent from deterioration of the fuel
in fuel system and carburetor.
The failures of fuel system or engine performance
arising from improper storage are beyond the scope
of the warranty.

any appliance that operates with a flame, such as a furnace,
water heater, or clothes dryer. Also avoid any area with a spark-
producing electric motor, or where power tools are operated.
If possible, avoid storage areas with high humidity, because that
promotes rust and corrosion.
Unless all fuel has been drained from the fuel tank, leave the fuel
valve lever in the OFF position to reduce the possibility of fuel
leakage.
Position the equipment so the engine is level. Tilting can cause
fuel or oil leakage.
With the engine and exhaust system cool, cover the engine to
keep out dust. A hot engine and exhaust system can ignite or
melt some materials. Do not use sheet plastic as a dust cover. A
nonporous cover will trap moisture around the engine, promoting
rust and corrosion.
If equipped with a battery for an electric starter, recharge the
battery once a month while the engine is in storage. This will help
to extend the service life of the battery.
Check your engine as described in the chapter CHECK BEFORE
OPERATION.
If the fuel was drained during storage preparation, fill the tank
with fresh gasoline. If you keep a container of gasoline for
refueling, be sure that it contains only fresh gasoline. Gasoline

REMOVAL FROM STORAGE
If the engine has been running, allow it to cool for at least 15
minutes before loading the engine-powered equipment on the
transport vehicle. A hot engine and exhaust system can burn you
and can ignite some materials.
Keep the engine level when transporting to reduce the possibility
of fuel leakage. Move the fuel valve lever to the OFF position.
TRANSPORTING
Change the engine oil.
Remove the spark plugs.
Pour a tablespoon (5-10 cc) of clean engine oil into the
cylinder.
Pull the starter rope several times to distribute the oil in the

Reinstall the spark plugs.
Pull the starter rope slowly until resistance is felt. This

technical or warranty inquires.
Engine serial number:
The combustion process produces carbon monoxide, oxides of
nitrogen, and hydrocarbons. Control of hydrocarbons and oxides
of nitrogen is very important because, under certain conditions,
they react to form photochemical smog when subjected to
sunlight. Carbon monoxide does not react in the same way, but it
is toxic.
reduce the emissions of carbon monoxide, oxides of nitrogen and
hydrocarbons.
Tampering and Altering
Tampering with or altering the emission control system may
increase emissions beyond the legal limit. Among those acts that
constitute tampering are:
Removal or alteration of any part of the intake, fuel or exhaust
systems.
Altering or defeating the governor linkage or speed-adjusting
mechanism to cause the engine to operate outside its design
parameters.

Hard starting or stalling after starting.

The emission control systems on your engine were designed, built.
We recommend the use of genuine parts whenever you have
maintenance done. These original-design replacement parts are
manufactured to the same standards as the original parts, so you
can be coQĆGHQW of their performance. The use of replacement
parts that are not of the original design and quality may impair the
effectiveness of your emission control system.
A manufacturer of an aftermarket part assumes the responsibility
that the part will not adversely affect emission performance. The
manufacturer or rebuilder of the part must certify that use of
the part will not result in a failure of the engine to comply with
emission regulations.
Follow the maintenance schedule. Remember that this schedule
is based on the assumption that your machine will be used for
its designed purpose. Sustained high-load or high-temperature
operation, or use in unusually wet or dusty conditions, will require
more frequent service.

HIGH ALTITUDE KIT REPLACEMENT FOR EPAIII ENGINES
At high altitude, the standard carburetor air-fuel mixture will
be too rich. Performance will decrease and fuel consumption
will increase. A very rich mixture will also foul the spark plug
and cause hard starting. Operation at an altitude that differs
from that at which this engine was FHUWLĆHG for extended
periods of time, may increase emissions.
