SAFETY
WARNING
• Do not touch hot radiator, or open reservoir when engine is
running
• Allow engine to cool before removing radiator cap, changing,
or adding coolant.
If engine is warm DO NOT remove radiator
cap.
Escaping steam can cause burns.
WARNING
Never remove radiator cap or radiator
reservoir cap while the engine is hot or
running. Severe thermal burns or injury
can occur by escaping steam or hot
engine coolant.
• Stop engine and allow to cool before removing radiator or
reservoir cap.
• To remove reservoir cap after engine is cool, place a thick
cloth over cap and remove it slowly.
• To remove radiator cap after engine is cool, place a thick
cloth over cap and rotate it slowly counter-clockwise to the
first stop. Pressurized steam may emit from the cap, stand
back to avoid injury. Once all pressure is released, rotate cap
counter-clockwise while pushing down on cap to remove.
WARNING
Unintentional sparking can result in
fire or electric shock.
Unintentional start-up can result in
entanglement, traumatic amputation,
or laceration.
BEFORE PERFORMING ADJUSTMENTS OR
REPAIRS
• Disconnect spark plug wire and keep it away from spark
plug.
• Disconnect battery at negative terminal.
WHEN TESTING FOR SPARK
• Use approved spark plug tester.
• Do not check for spark with spark plug removed.
WARNING
Briggs & Stratton does not approve or authorize the use of
these engines on 3-wheel All Terrain Vehicles (ATVs), motor
bikes, fun/recreational go-karts, aircraft products or vehicles
intended for use in competitive events. Use of these engines in
such applications could result in property damage, serious
injury (including paralysis), or even death.
ENGINE INFORMATION
TECHNICAL INFORMATION
Engine Power Rating Information
The gross power rating for individual gas engine models is labeled
in accordance with SAE (Society of Automotive Engineers) code
J1940 (Small Engine Power & Torque Rating Procedure), and
rating performance has been obtained and corrected in
accordance with SAE J1995 (Revision 2002-05). Actual gross
engine power will be lower and is affected by, among other things,
ambient operating conditions and engine-to-engine variability.
Given both the wide array of products on which engines are
placed and the variety of environmental issues applicable to
operating the equipment, the gas engine will not develop the rated
gross power when used in a given piece of power equipment
(actual “on-site” or net horsepower). This difference is due to a
variety of factors including, but not limited to, accessories (air
cleaner, exhaust, charging, cooling, carburetor, fuel pump, etc.),
application limitations, ambient operating conditions (temperature,
humidity, altitude), and engine-to-engine variability. Due to
manufacturing and capacity limitations, Briggs & Stratton may
substitute an engine of higher rated power for this Series engine.
