POWER RATINGS
The power ratingsfor an individualengine 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.
Check Crankcase Oil Level before starting engine and after
each 8 hours of continuous use (see Figure 25). Add the
recommended motor oil as required.
NOTE: Overfilling the engine can affect performance.
Tighten the oil fill cap securely to prevent leakage.

Change Oil every 50 hours of operation or at least once a
year, even ifthe snow blower is not used for fifty hours_ Use
a clean, highquality detergentoil. Fillthe crank case to FULL
line on dipstick(see Figure 25). Be sure originalcontainer is
marked: A.P.I. service "SF" or higher.Do not use SAE10W40
oil (as it may not provideproper lubrication).See Chart for oil
recommendations.
To Drain Oil - Positionsnow blower so that the oil drain plug
is lowest point on engine. When the engine is warm, remove
oil drain plug and oil fill cap and drain oil into a suitable
container (Figure 26).
Replace oil drain plug and tighten securely. Refill crank case
with the recommended motor oil.
