LUBRICATION
How To Lubricate
The Jackshaft Assembly
A grease fitting is provided to lubricate the
jackshaft assembly. Use a grease gun with au-
tomotive type grease to lubricate the jackshaft
assembly as shown in Figure 10.

Grease Fitting
How To Change Engine Oil
Change the engine oil when the engine is
warm. For the proper oil capacity, see the en-
gine manufacturer’s instructions.
1. Disconnect spark plug wire from the spark
plug.
2. Remove the oil drain plug as shown in
Figure 11.
3. Drain all the engine oil into a flat pan.
4. Install the oil drain plug. Make sure the
oil drain plug is tight.
5. Remove the dipstick.
6. Fill the engine crankcase. DO NOT
OVERFILL. For proper oil capacity, see
the engine manufacturer’s instructions.
7. Connect the spark plug wire to the spark
plug.

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). 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 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.
