Craftsman 580.327130 Operator's Manual page 10

• A vacuum cleaner may be used to pick up loose
dirt and debris.
• Low pressure air (not to exceed 25 psi) may be
used to blow away dirt. Inspect cooling air slots
and openings on the generator. These openings
must be kept clean and unobstructed.
ENGINE MAINTENANCE
DANGER
: When working on the generator,
always disconnect spark plug wire from spark
plug and keep it away from spark plug.
Checking Oil Level
Oil level should be checked prior to each use or at
least every 8 hours of operation. Keep oil level
maintained.
Changing Engine Oil and Oil Filter
Change oil after first 8 hours of operation. Change oil
every 50 hours thereafter. If you are using your
generator under extremely dirty or dusty conditions, or
in extremely hot weather, change oil more often.
Change oil while engine is still warm from running, as
follows:
• Clean area around oil drain plug.
• Remove oil drain plug and oil fill plug and drain oil
completely into a suitable container.
• When oil has completely drained, install oil drain
plug and tighten securely.
• Place a suitable container beneath the oil filter and
turn filter counterclockwise to remove. Discard
according to local regulations.
• Coat gasket of new filter (p/n 70185) with engine
oil. Turn filter clockwise until gasket snugs against
the filter adapter. Then tighten filter an additional
3/4 turn.
• Fill oil sump with recommended oil (see page 6).
• Install the oil fill plug and tighten securely.
Clean/Replace Spark Plug
Change the spark plug every 100 hours of operation
or once each year, whichever comes first. This will
help your engine to start easier and run better.
Replace with recommended spark plug, as follows.
• Clean area around spark plug, then remove and
inspect it. Replace spark plug if electrodes are
pitted, burned or porcelain is cracked.
• Check new spark plug electrode gap with wire
feeler gauge and set gap to 0.030 inch (0.76mm).
Retorque Head Bolts
After 50 hours of operation, retorque the head bolts for
this engine to 3.1 kg/m (22 foot-pounds). The torque
sequence is A, B, C, D, E (star pattern).
A
IMPORTANT: If you feel uncomfortable about doing
this procedure or you don't have the proper tools,
please take your generator in to the nearest Sears
service center to have the head bolts retorqued. This
is a very important step to insure the longest life for
your engine.
Service Air Cleaner
Your engine will not run properly and may be
damaged if you run it using a dirty air cleaner.
Clean or replace the air cleaner paper filter once every
25 hours of operation or once a year, whichever
comes first. Clean or replace more often if operating
under dusty or dirty conditions. Clean foam
pre–cleaner every 25 hours of operation or sooner
under dusty conditions.
To clean or replace foam pre–cleaner:
• Remove air cleaner cover, then foam pre-filter.
• Wash pre–cleaner in soapy water. Squeeze pre-
filter dry in clean cloth (DO NOT TWIST).
• Clean air cleaner cover before installing it.
To clean or replace paper air filter:
• Remove air cleaner cover; then remove foam pre-
filter (service if necessary) and remove paper filter.
• Clean paper filter by tapping it gently on a solid
surface. If the filter is too dirty, replace it with a new
one. Dispose of the old filter properly.
