BEFORE OPERATION CHECKS

IS YOUR ENGINE READY TO GO?
For your safety, to ensure compliance with environmental
regulations, and to maximize the service life of your equipment,
it is very important to take a few moments before you operate
the engine to check its condition. Be sure to take care of any
problem you find, or have your servicing dealer correct it,
before you operate the engine.
Failure to properly maintain this engine, or failing to
correct a problem before operation, could result in a
significant malfunction.
Some malfunctions can cause serious injuries or
death.
Always perform a pre-operation inspection before
each operation and correct any problems.
Before beginning your pre-operation checks, be sure the engine
is level and the engine switch is in the OFF position.
Always check the following items before you start the engine:
Check the General Condition of the Engine
1. Before each use, look around and underneath the engine for
signs of oil or gasoline leaks.
2. Remove any excessive dirt or debris, especially around the
muffler and recoil starter.
3. Look for signs of damage.
4. Check that all shields and covers are in place, and all nuts,
bolts, and screws are tightened.
Check the Engine
1. Check the fuel level (see page 4). Starting with a full tank will
help to eliminate or reduce operating interruptions for
refueling.
2. Check the engine oil level (see page 5). Running the engine
with a low oil level can cause engine damage.
3. Check the air filter element (see page 5). A dirty air filter
element will restrict air flow to the carburetor, reducing
engine performance.
4. Check the equipment powered by this engine.
Review the instructions provided with the equipment
powered by this engine for any precautions and procedures
that should be followed before engine startup.

SAFE OPERATING PRECAUTIONS

Before operating the engine for the first time, please review the

SAFETY INFORMATION

OPERATION CHECKS .
Carbon Monoxide Hazards
For your safety, do not operate the engine in an enclosed area
such as a garage. Your engine's exhaust contains poisonous
carbon monoxide gas that can collect rapidly in an enclosed
area and cause illness or death.
Exhaust contains poisonous carbon monoxide gas
that can build up to dangerous levels in closed areas.
Breathing carbon monoxide can cause
unconsciousness or death.
Never run the engine in a closed or even partially
closed area.
Review the instructions provided with the equipment powered
by this engine for any safety precautions that should be
observed with engine startup, shutdown, or operation.

STARTING THE ENGINE

See Figure 1, page A-2.
Refer to the instructions provided with the equipment for
throttle lever and engine switch.
1. To start a cold engine, move the choke lever [1] to the
CLOSED [A] position.
To restart a warm engine, leave the choke lever in the OPEN
[B] position.
2. Press the priming pump [2] several times until the priming
pump is filled with fuel.
Even if the priming pump is pressed too many times, the
extra fuel will return to the fuel tank.
If the priming pump is not pressed enough, the engine may
not start.
3. Turn the engine switch [3] to the ON ( ) [A] position.
4. Pull the starter grip [4] lightly until you feel resistance, then
pull briskly in the direction of the arrow [5]. Return the starter
grip gently.
Do not allow the starter grip to snap back against the engine.
Return it gently to prevent damage to the starter.
5. If the choke lever was moved to the CLOSED [A] position to
start the engine, gradually move it to the OPEN [B] position
as the engine warms up.
