WARNING :
The engine exhaust from this product contains
chemicals known to the State of California to
cause cancer, birth defects or other reproductive
harm.
To show compliance with California emission regulations, a hangtag has been provided
displaying the Air Index level and durability period of this engine.
The Air Index level defines how clean an engine’s exhaust is over a period of time. A bar
graph scaled from “0” (most clean) to “10” (least clean) is used to show an engine’s Air Index
level. A lower Air Index level represents cleaner exhaust from an engine.
The period of time (in hours) that the Air Index level is measured is known as the durability
period. Depending on the size of the engine, a selection of time periods can be used to
measure the Air Index level (see below).
Notice : This hangtag must remain on this engine or piece of equipment, and only be
removed by the ultimate purchaser before operation.

EXHAUST PRECAUTIONS
■Never inhale exhaust gas.
It contains carbon monoxide, a
colorless, odorless and extremely
dangerous gas which can cause
unconsciousness or death.
■Never operate the engine indoors or
in a poorly ventilated area, such as
tunnel, cave, etc.
■Exercise extreme care when
operating the engine near people or
animals.
■Keep the exhaust pipe free of foreign
objects.

ENGLISH
SURROUNDINGS
■Operate the engine on a stable, level
surface free of small rocks, loose
gravel, etc.
−2−
PROTECTIVE COVER
■Place the protective covers over
the rotating parts.
If rotating parts such as the drive
shaft, pulley, belt, etc. are left
exposed, they are potentially
hazardous.
To prevent injury, equip them with
protective covers or shrouds.
■Be careful of hot parts.
The muffler and other engine parts

running or just after it has stopped.
Operate the engine in a safe area
and keep children away from the
running engine.
■Never make adjustments on the
machinery while it is connected to the
engine, without first removing the
ignition cable from the spark plug.
Turning the crankshaft by hand
during adjusting or cleaning might
start the engine, and the machinery
with it, causing serious injury to the
operator.
■Never run the engine with governor
disconnected, or operate at speeds
in excess of 3600 rpm load.
NOTE
Operating the engine at a steep
incline may cause seizure due to
improper lubrication even with a
maximum oil level.
EH72FIusEU694309.12.213:07PMページ2

PRE-OPERATION CHECKS .
■Carefully check fuel hoses and

CHECK FUEL
■The fuel tank shall be provided
separately, because the engine is not
equipped with a fuel tank.
A fuel valve and fuel filter should be
connected between the fuel tank and
fuel pump.
Securely connect with fuel hoses to the
fuel pump to prevent leakage.
■ Fuel tanks may be mounted up to 0.66
meters (2 feet) below the throttle body.
If the fuel tank is mounted above the
throttle body, a fuel shut off valve must
be
connected between the fuel tank
and fuel pump. The fuel valve must be
shut off when the engine is not
operating to
prevent fuel from flooding
the throttle body.
■ A serious accident may occur if the fuel
hose comes off. Properly secure the fuel
line connections by completely inserting
the hose onto the fittings and securing
the connection with a hose clamp.
■ Use automotive unleaded gasoline only.
■Stop the engine and close the fuel
valve before filling the fuel tank.
■Wipe off any spilled fuel before starting
the engine.
WARNING
Do not refuel while smoking, near an
open flame or other potential hazards.
