ENGINE
POWER RATINGS
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). Torque values are
derived at 3060 RPM; horsepower values are derived at
3600 RPM. 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 power). 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.
Check Crankcase Oil Level before starting engine and after
each 8 hours of continuous use (see Figure 26). 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 if the snow blower is not used for fifty hours. Use
a clean, high quality detergent oil. Fill the crank case to FULL
line on dipstick (see Figure 26). Be sure original container is
marked: A.P.I. service "SF" or higher. Do not use SAE10W40
oil (as it may not provide proper lubrication). See Chart for oil
recommendations.
To Drain Oil − Position snow 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 27).
Replace oil drain plug and tighten securely. Refill crank case
with the recommended motor oil.
