and cylinders. Please check with your authorized Subaru en-
gine service dealer for assistance. Only operate the engine
after it has cooled and the cause of the problem has been
corrected. The high oil temperature alarm system does not
replace proper service and maintenance and the checking of
the oil level and cooling system before the engine is started.
Always check for proper oil level and unobstructed air
cooling intake and passages before starting the engine.
WINTER/SUMMER INTAKE AIR CONTROL
(IF SO EQUIPPED)
Under certain weather conditions (temperatures below 40° F
(4° C) and a high dew point), the engine may experience ic-
ing of the carburetor and/or the crankcase breather system.
To eliminate this problem, this engine may be fi tted with a
winter/summer valve (Figure 4). This directs hot air into the
carburetor during cold weather operation. Always make sure
the winter/summer valve is in the correct location relative to
the weather conditions.

GENERAL MAINTENANCE
RECOMMENDATIONS
PERFORMING SCHEDULED MAINTENANCE
It is important to perform service as specifi ed in the Main-
tenance Schedule for proper engine operation, and to
ensure that the engine complies with the applicable emis-
sion standards for the duration of its useful life. Service and
repairs may be performed by any capable person or repair
shop. Additionally, emissions critical maintenance must be
performed as scheduled in order for the Emissions Waranty
to be valid. Emissions critical maintenance consists of ser-
vicing the air fi lter and spark plugs in accordance with the
Maintenance Schedule.
CHECKING THE OIL LEVEL
See the “BEFORE STARTING THE ENGINE” section for
information on checking the oil level. The oil level should be
checked before each use, or at least every eight (8) hours of
operation. Keep the oil level maintained.
CHANGING THE OIL AND FILTER
The engine is equipped with an oil fi lter. Change the oil and
fi lter after the fi rst eight (8) hours of operation. Change
the oil and oil fi lter every 100 hours thereafter. If using this
engine under dirty or dusty conditions, or in extremely hot
weather, change the oil more often.
Use the following instructions to change the oil while the
engine is still warm:
1 Clean the area around the oil drain plug, remove the
plug and drain the oil completely into a suitable
container (Figure 5).
