To Clean the Generator:
• Use a damp cloth to wipe exterior surfaces clean.
• A soft, bristle brush may be used to loosen caked on
dirt, oil, etc.
• 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 negative cable from battery.
Also disconnect spark plug wires from spark
plug and keep wire away from spark plug.
Checking
Oil Level
See the "BEFORE STARTING THE GENERATOR"
section 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.
• 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 with engine oil. Turn filter
clockwise until gasket contacts tightly with filter
adapter. Then tighten an additional 3/4 turn.
• Fill oil sump with recommended
oil. (See "BEFORE
STARTING THE GENERATOR" on page 9 for oil
recommendations).
• Install the oil fill plug and tighten securely.
• Wipe up any spilled oil.
Replacing
the Spark Plug
Use Champion RC12YC spark plug or equivalent. The
correct air gap is 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 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 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).
