Sparking can ignite nearby flammable gases.
Explosion and fire could result.

• If there is natural or LP gas leakage in area, do not start engine.
• Do not use pressurized starting fluids because vapors are flammable.

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, 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.

  Fuel System See Figure: 13

Store the engine level (normal operating position). Fill fuel tank (A, Figure 13) with fuel.
To allow for expansion of fuel, do not overfill above the fuel tank neck (B).
Fuel can become stale when kept in a storage container for more than 30 days. Each time you fill the container with fuel, add fuel stabilizer to the fuel as specified by the manufacturer’s instructions. This keeps fuel fresh and decreases fuel-related problems or contamination in the fuel system.
It is not necessary to drain fuel from the engine when fuel stabilizer is added as instructed. Before storage, turn the engine ON for 2 minutes to move the fuel and stabilizer  through the fuel system.
If gasoline in the engine has not been treated with a fuel stabilizer, it must be drained into an approved container. Run the engine until it stops from lack of fuel. The use of a fuel stabilizer in the storage container is recommended to maintain freshness.

Where a warrantable condition exists, B&S will repair your engine at no cost to you including diagnosis, parts, and labor.
Manufacturer’s Warranty Coverage:
The exhaust emissions control system on your engine is warranted for two years.
If any emissions-related part on your engine is defective, the part will be repaired or replaced by B&S.

Owner’s Warranty Responsibilities:

• As the engine owner, you are responsible for the performance of the required maintenance listed in your owner’s manual.  B&S recommends that you retain all receipts  covering maintenance on your engine, but B&S cannot deny warranty coverage solely for the lack of receipts or for your failure to ensure the performance of all  scheduled maintenance.
• As the engine owner, you should however be aware that B&S may deny you warranty coverage if your engine or a part has failed due to abuse, neglect, or improper  maintenance or unapproved modifications.
• You are responsible for presenting your engine to a B&S 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 a question regarding your warranty rights and responsibilities, you should contact B&S at 1-800-444-7774  (in USA) or BRIGGSandSTRATTON.COM.
