ENGINE SAFETY

IMPORTANT SAFETY INFORMATION

Owner Responsibilities

Refuel With Care

Most accidents with engines can be prevented if you follow all

instructions in this manual and on the engine. Some of the most

common hazards are discussed below, along with the best way to

protect yourself and others.

Honda engines are designed to give safe and dependable service if

operated according to instructions. Read and understand this

owner’s manual before operating the engine. Failure to do so could

result in personal injury or equipment damage.

Know how to stop the engine quickly, and understand the operation

of all controls. Never permit anyone to operate the engine without

proper instructions.

Do not allow children to operate the engine. Keep children and pets

away from the area of operation.

Gasoline is extremely flammable, and gasoline vapor can explode.

Refuel outdoors, in a well-ventilated area, with the engine stopped.

Never smoke near gasoline, and keep other flames and sparks away.

Always store gasoline in an approved container. If any fuel is spilled,

make sure the area is dry before starting the engine.

ENGINE SAFETY

Hot Exhaust

Other Equipment

Carbon Monoxide Hazard

The muffler becomes very hot during operation and remains hot for a

while after stopping the engine. Be careful not to touch the muffler

while it is hot. Let the engine cool before storing it indoors.

Exhaust gas contains poisonous carbon monoxide. Avoid inhalation of

exhaust gas. Never run the engine in a closed garage or confined area.

Review the instructions provided with the equipment powered by this

engine for any additional safety precautions that should be observed

in conjunction with engine startup, shutdown, operation, or protective

apparel that may be needed to operate the equipment.

The centrifugal clutch automatically engages and transmits power

when engine speed is increased above approximately 4,000 rpm. At

BEFORE OPERATION

IS YOUR ENGINE READY TO GO?

Check the General Condition of the Engine

For your safety, 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.

Improperly maintaining this engine,

or failing to correct a problem

before operation, could cause a

malfunction in which you could be

seriously injured.

Always perform a preoperation

inspection before each operation,

and correct any problem.

Before beginning your preoperation checks, be sure the engine is level

and the ignition switch on the equipment is in the OFF position.

Look around and underneath the engine for signs of oil or gasoline

leaks.

Remove any excessive dirt or debris, especially around the muffler

and recoil starter.

Look for signs of damage.

Check that all shields and covers are in place, and all nuts, bolts, and

screws are tightened.

01/04/03 12:07:34 31ZM3601_013

BEFORE OPERATION

Check the Engine

Check the Equipment Powered by This Engine

Check the engine oil level (see page ). Running the engine with a

low oil level can cause engine damage.

Check the air filter (see page ). A dirty air filter will restrict air flow

to the carburetor, reducing engine performance.

Check that all nuts, bolts, and screws are tightened.

Check the fuel level. Starting with a full tank will help to eliminate or

reduce operating interruptions for refueling.

Review the instructions provided with the equipment powered by this

engine for any precautions and procedures that should be followed

before engine startup.

BEFORE OPERATION

To start a cold engine, move the choke lever to the CLOSED position.

To restart a warm engine, leave the choke lever in the OPEN position.

Review the instructions provided with the equipment powered by this

engine for any safety precautions that should be observed in

conjunction with engine startup, shutdown, or operation.

Breathing it can cause

unconsciousness and even kill you.

Avoid any areas or actions that

expose you to carbon monoxide.

OPERATION

Hot Restart

IMPORTANT SAFETY PRECAUTION

CHOKE LEVER

OOPPEENN

Follow the STARTING THE ENGINE procedure on page and start

the engine with the choke lever in the OPEN position.

If the engine is operated at higher ambient temperatures then turned

off and allowed to sit for a short time, if may not restart on the first pull.

If necessary, use the following procedure:

The ignition switch and the throttle lever are located on the equipment

not on the engine.

Turn the ignition switch to the OFF position.

Move the choke lever to the OPEN position.

Hold the throttle lever in the full throttle position.

Pull the starter grip 3 to 5 times.

If the choke lever was moved to the CLOSED position to start the

engine, gradually move it to the OPEN position as the engine warms

up.

Turn the ignition switch to the OFF position before performing the

following procedure. This will prevent the engine from starting and

running at maximum speed when the throttle is in the full throttle

position. If the engine starts, with the throttle in the full throttle

position, the equipment can move forward rapidly or the trimmer

attachment can spin at maximum speed. This may result in personal

injury.
