SAFETY
WARNING
If engine is warm DO NOT remove
radiator cap.
Escaping steam can cause burns.
•
Do not touch hot radiator, or open reservoir when engine is
running
•
Allow engine to cool before removing radiator cap, changing,
or adding coolant.
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.
ENGINE INFORMATION
TECHNICAL INFORMATION
Power Ratings: The power ratings for an individual engine model
are initially developed by starting with SAE (Society of Automotive
Engineers) code J1940 (Small Engine Power & Torque Rating
Procedure) (Revision 2002-05). Given both the wide array of
products on which our engines are placed, and the variety of
environmental issues applicable to operating the equipment, it may
be that the engine you have purchased will not develop the rated
horsepower when used in a piece of power equipment (actual
“on-site” power). This difference is due to a variety of factors
including, but not limited to, the following: differences in altitude,
temperature, barometric pressure, humidity, fuel, engine lubrication,
maximum governed engine speed, individual engine to engine
variability, design of the particular piece of power equipment, the
manner in which the engine is operated, engine run-in to reduce
friction and clean out of combustion chambers, adjustments to the
valves and carburetor, and other factors. The power ratings may also
be adjusted based on comparisons to other similar engines utilized
in similar applications, and will therefore not necessarily match the
values derived using the foregoing codes.
