WARNING
POISONOUS GAS HAZARD. Engine exhaust contains carbon
monoxide, a poisonous gas that could kill you in minutes. You
CANNOT see it, smell it, or taste it. Even if you do not smell exhaust
fumes, you could still be exposed to carbon monoxide gas. If you start
to feel sick, dizzy, or weak while using this product, shut it off and get
to fresh air RIGHT AWAY. See a doctor. You may have carbon
monoxide poisoning.
Operate this product ONLY outside far away from windows, doors and vents to

reduce the risk of carbon monoxide gas from accumulating and potentially being
drawn towards occupied spaces.
Install battery--operated carbon monoxide alarms or plug--in carbon monoxide

alarms with battery back-up according to the manufacturer's instructions.
Smoke alarms cannot detect carbon monoxide gas.
DO NOT run this product inside homes, garages, basements, crawlspaces,

sheds, or other partially-enclosed spaces even if using fans or opening doors
and windows for ventilation. Carbon monoxide can quickly build up in these
spaces and can linger for hours, even after this product has shut off.
ALWAYS place this product downwind and point the engine exhaust away from

occupied spaces.
WARNING
Rapid retraction of starter cord (kickback) will pull hand and arm
toward engine faster than you can let go.
Broken bones, fractures, bruises or sprains could result.
When starting engine, pull the starter cord slowly until resistance is felt and then

pull rapidly to avoid kickback.
Remove all external equipment/engine loads before starting engine.

Direct-coupled equipment components such as, but not limited to, blades,

impellers, pulleys, sprockets, etc., must be securely attached.
WARNING
Missing or inoperative "fuel lock-off" valve can cause a fire or
explosion.
Do not operate the equipment if the "fuel lock-off" valve is missing or inoperative.

WARNING
Rotating parts can contact or entangle hands, feet, hair, clothing, or
accessories.
Traumatic amputation or severe laceration can result.
Operate equipment with guards in place.

Keep hands and feet away from rotating parts.

Tie up long hair and remove jewelry.

Do not wear loose-fitting clothing, dangling drawstrings or items that could

become caught.

WARNING
Running engines produce heat. Engine parts, especially muffler,
become extremely hot.
Severe thermal burns can occur on contact.
Combustible debris, such as leaves, grass, brush, etc. can catch fire.
Allow muffler, engine cylinder and fins to cool before touching.

Remove accumulated debris from muffler area and cylinder area.

It is a violation of California Public Resource Code, Section 4442, to use or

operate the engine on any forest-covered, brush-covered, or grass-covered land
unless the exhaust system is equipped with a spark arrester, as defined in
Section 4442, maintained in effective working order. Other states or federal
jurisdictions may have similar laws. Contact the original equipment
manufacturer, retailer, or dealer to obtain a spark arrester designed for the
exhaust system installed on this engine.
WARNING
Unintentional sparking can result in fire or electric shock.
Unintentional start-up can result in entanglement, traumatic
amputation, or laceration.
Fire hazard
Before performing adjustments or repairs:
Disconnect the spark plug wire and keep it away from the spark plug.



Use only correct tools.

Do not tamper with governor spring, links or other parts to increase engine

speed.
Replacement parts must be of the same design and installed in the same

position as the original parts. Other parts may not perform as well, may damage
the unit, and may result in injury.
Do not strike the flywheel with a hammer or hard object because the flywheel

may later shatter during operation.
When testing for spark:
Use approved spark plug tester.

Do not check for spark with spark plug removed.



Do not use a phone in the vicinity.

Evacuate the area.
