Engine Maintenance
_
ANGER!
When working on the generator,
always disconnect negative cable from battery.
Also disconnect spark plug wires from spark
plug and keep wire away from spark plug.
Checking Oil Level
See "BEFORE STARTING THE GENERATOR"
on
page 9 for information on checking the oil level. The
oil level should be checked before each use, or at
least every eight hours of operation.
Keep the oil
level maintained.
Changing the Oil and Oil Filter
Change the oil and filter after the first eight hours of
operation.
Change the oil every 50 hours
thereafter.
If you are running this unit 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:
•
Clean area around oil drain plug and oil fill cap.
•
Remove oil fill cap and oil drain plug. 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 with fresh clean engine
oil. Turn filter clockwise until gasket contacts tightly
with filter adapter. Then tighten 3/4 turn more.
•
Fill engine with recommended oil. (See "BEFORE
STARTING THE Generator" on page 9 for oil
recommendations).
•
Install the oil fill cap and tighten securely.
•
Wipe up any spilled oil.
Replacing the Spark Plug
Use the recommended
spark plug gapped to 0.76 mm
(0.030 in.). Replace the plug every 100 hours of
operation
or once each year, whichever comes first.
This will help your engine start easier and run better.
1. Stop the engine and pull the spark plug wire off of
the spark plug.
2. Clean the area around the spark plug and remove
it from the cylinder head.
3. Set the spark plug's gap to 0.76 mm (0.030 in.).
Install the correctly gapped spark plug into the
cylinder head.
Retorque Head Bolts
After the first 50 hours of operation, you must retorque
the head bolts to 6.9 kg.-m. (44 ft.-Ibs.).
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 re-torqued. This
is a very important step to insure the longest life for
your engine.
NOTE: Only perform this adjustment after the first
50 hours of operation. The head bolts will need no
further adjustment.
•
Torque sequence is as follows: A, B, C, D,
(alternating pattern).
