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
plugs and keep wires away from spark plugs.
Checking
Oil Level
See the "BEFORE STARTING THE GENERATOR"
section on page 8 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 properly 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 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.
2. When the oil is drained, install and tighten the oil
drain plug.
3. Place a suitable container beneath the oil filter and
turn the filter counterclockwise
to remove the filter.
4. Lightly coat the gasket of a new filter with fresh
engine oil. Turn the new filter clockwise until the
gasket contacts the filter adapter, then tighten an
additional 3/4 turn.
5. Remove the oil fill cap and insert a clean funnel
into the cap opening. Slowly fill the crankcase with
the recommended
oil until the oil level is at the
FULL mark.
6. When the crankcase is filled to the proper level,
install and tighten the oil fill cap.
Replacing
the Spark Plugs
Use the recommended
spark plugs set to the correct
air gap [0.76 mm (0.030 in.)]. Replace the plugs
every 100 hours of operation
or once each year,
whichever comes first. This will help your engine to
start easier and run better.
1. Stop the engine and pull the spark plug wires off of
the spark plugs.
2. Clean around the spark plugs and remove them
from the cylinder head.
3. Set the spark plugs' gap to 0.76 mm (0.030 in.).
Install the correctly gapped spark plugs into the
cylinder heads.
Service Air Cleaner
Your equipment's air cleaner is one of the most
important areas to maintain. This engine will not run
properly and may get damaged if it is run with a dirty
air cleaner system.
Clean the foam pre-cleaner every 25 hours of
operation,
or sooner under dusty or dirty conditions.
Clean or replace the paper air filter every 50 hours of
operation
or once a year, whichever comes first.
Clean or replace the filter more often if the engine is
operated under dusty or dirty conditions.
_
CAUTION:
Never run this equipment without
the complete air cleaner system installed on the
engine. This could result in premature wear to
the engine.
Use the following instructions to clean or replace the
air cleaner components:
1. Remove the cover by loosening both hold-down
straps.
2. Slide the foam pre-cleaner off the cartridge.
