WARNING
Rapid retraction of starter cord (kick-
back) 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 cord slowly until
resistance is felt, then pull rapidly.
• Remove all external equipment/engine loads before
starting engine.
• Direct coupled equipment components such as, but
not limited to, blades, impellors, pulleys, sprockets,
etc., must be securely attached.
WARNING
Engines give off carbon monoxide, an
odorless, colorless, poison gas.
Breathing carbon monoxide can
cause nausea, fainting or death.
• Start and run engine outdoors.
• Do not start or run engine in enclosed area, even if
doors or windows are open.
TECHNICAL INFORMATION
POWER RATINGS: The power ratings for an individual engine
model are initially developed by starting with SAE (Society of Auto-
motive 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 en-
vironmental 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, tempera-
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 (only engines
with electric start).
• Unplug power supply (only engines equipped with
120V electric start)
WHEN TESTING FOR SPARK
• Use approved spark plug tester.
• Do not check for spark with spark plug removed.
ENGINE INFORMATION
ture, barometric pressure, humidity, fuel, engine lubrication, maxi-
mum governed engine speed, individual engine to engine variabil-
ity, 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.
