ENGINE SAFETY PRECAUTIONS
Warning Carbon Monoxide Poisoning
All engines contain carbon monoxide in their exhaust. Carbon monoxide is a deadly, colorless, tasteless, odorless gas
which may be present even if you do not smell or see any engine exhaust. Levels of carbon monoxide, which can be
deadly, can be present for days in an enclosed area that has poor ventilation. Any level of carbon monoxide, if
inhaled, can cause headaches, drowsiness, nausea, dizziness, confusion and eventually death. If you experience any of
these symptoms, seek fresh air and medical attention immediately.
Preventing Carbon Monoxide Poisoning
Never run engine indoors.
•Never try to ventilate engine exhaust indoors. Carbon monoxide can reach dangerous levels very quickly.
•Never run engine outdoors where exhaust fumes may be pulled into a building.
•Never run engine outdoors in a poorly ventilated area where the exhaust fumes may be trapped and not easily taken
away. (Examples include: in a large hole or areas where hills surround your working area.)
•Never run engine in an enclosed or partially enclosed area. (Examples include: buildings that are enclosed on one or
more sides, under tents, car ports or basements.)
•Always run the engine with the exhaust and muffler pointed in the direction away from the operator.
•Never point the exhaust muffler towards anyone. People should always be many feet away from the operation of the
engine and its attachments.
Gasoline Fires and Handling Fuel Safely
Fuel and fuel vapors are highly flammable. Never use fuel where a spark or flame may be present. Never use fuel where
a potential source of ignition could occur. (Examples include: hot water or space heaters, clothes dryer, electric motors, etc.)
Keep flames and sparks away from engine and fuel to prevent fires. Fuel fires spread very quickly and are highly
explosive.
Prevention of Gasoline Fires
•Never fill your fuel tank indoors. (Examples include: basement, garage, barn, shed, house, porch, etc.)
Always fill fuel tank outside in a well-ventilated area.
•Never remove the fuel cap or add fuel with the engine running. Stop engine and allow to cool before filling.
•Never drain fuel from engine in an enclosed area.
•Always wipe up excess (spilled) fuel from engine before starting. Clean up spilled fuel immediately.
•Allow spilled fuel to dry, after wiping and before starting.
•Allow fuel fumes/vapors to escape from the area before starting engine.
•Test the fuel cap for proper installation before starting and using engine.
•Always run the engine with fuel cap properly installed on the engine.
•Never smoke while refilling engine fuel tank.

!
!
6!
•Prevent fire and explosion caused by static electric discharge. Use only nonmetal, portable fuel containers
approved by the UnderwriterʼsLaboratory (U.L.) or the American Society for Testing & Materials (ASTM).
•Do not store engine with fuel in fuel tank indoors. Fuel and fuel vapors are highly explosive.
•During storage, screw down gas cap vent screw tightly.
•Never pour fuel from engine fuel tank.
•Never siphon fuel by mouth to drain fuel tank.
•Always have an adult fill the fuel tank.
•Never allow an adult or anyone under the influence of drugs or alcohol to fill engine.
•Never allow children to fill the engine.
•The clutch will transfer maximum power after about two hours of normal operation. During this break-in period clutch
slippage may occur. The clutch should be kept free of oil or other moisture for efficient operation.
BURNS AND FIRES
The muffler, muffler guard and other parts of the engine become extremely hot during the operation of the engine.
These parts remain extremely hot after the engine has stopped. Do not touch.
Prevention of Burns and Fires
•Never remove the muffler guard from the engine.
•Never touch the muffler guard because it is extremely
hot and will cause severe burns.
•Never the engine that becomes hot after operation.
•Always keep materials and debris away from muffler
guard and other hot parts of the engine to avoid fires.
This engine is designed to operate using a catalytic
converter which contributes to the engineʼscompliance
with the EPA.

EMISSION CONTROL SYSTEM WARRANTY
Buffalo Corp.
Your Warranty Rights and Obligations
The California Air Resources Board, The United States Environmental Protection Agency (US EPA) and Buffalo Corp. are
pleased to explain the exhaust and evaporative emissions control system warranty on your 2019 model year small off-road
engine. In California, new equipment that use small off-road engines must be designed, built, and equipped to meet the
State’s stringent anti-smog standards. Buffalo Corp. must warrant the emissions control system on your small off-road
engine for the periods of time listed below provided there has been no abuse, neglect or improper maintenance of your small
off-road engine or equipment leading to the failure of the emissions control system.
Your emissions control system may include parts such as the carburetor or fuel-injection system, the ignition system,
catalytic converter, fuel tanks, fuel lines (for liquid fuel and fuel vapors), fuel caps, valves, canisters, filters, clamps and
other associated components. Also included may be hoses, belts, connectors, and other emission-related assemblies.
Where a warrantable condition exists, Buffalo Corp. will repair your small off-road engine at no cost to you including
diagnosis, parts and labor.
Manufacturer’s Warranty Coverage:
The exhaust and evaporative emissions control system on your small off-road engine is warranted for two years. If any
emissions-related part on your small off-road engine is defective, the part will be repaired or replaced by Buffalo Corp.
Owner’s Warranty Responsibility
As the small off-road engine owner, you are responsible for the performance of the required maintenance listed in your owner’s
manual. Buffalo Corp. recommends that you retain all receipts covering maintenance on your small off-road engine, but Buffalo
Corp. cannot deny warranty coverage solely for the lack of receipts or for your failure to ensure the performance of all scheduled
maintenance.
As the small off-road engine owner, you should however be aware that Buffalo Corp. may deny you warranty coverage if your
small off-road engine or a part has failed due to abuse, neglect, or improper maintenance or unapproved modifications.
You are responsible for presenting your small off-road engine to a Buffalo Corp. distribution center or service center as soon as the
problem exists. The warranty repairs shall be completed in a reasonable amount of time, not to exceed 30 days.
If you have any questions regarding your warranty rights and responsibilities, you should contact Buffalo Corp. customer
service representative at 1-866-460-9436 or write to [e-mail].

the small off-road engine (SORE)(1) has been designed, built and equipped so as to conform with all applicable regulations;
and (2) is free from defects in materials and workmanship that cause the failure of a warranted part to conform with those
regulations as may be applicable to the terms and conditions stated below.
(a) The warranty period begins on the date the engine is delivered to an ultimate purchaser or first placed into service. The
