MAINTENANCE
GENERAL RECOMMENDATIONS
The Owner/Operator is responsible for making sure that all
periodic maintenance tasks are completed on a timely
basis; that all discrepancies are corrected; and that the unit
is kept ctean and property stored. Never operate a dam-
aged or defective generator.
GENERATOR MAINTENANCE
Generator maintenance consists of keeping the unit clean
and dry. Operate and store the unit in a clean dry envior-
ment where it will not be exposed to exceesive dust, dirt,
moisture or any corrosive vapors. Cooling air slots in the
generator must not become dogged with snow, leaves or
any other foreign material.
Check the cleenliness of the generator fraquentiy and clean
when dust, dirt, oil, moisture or other foreign substances
are visible on its exterior surface.
NOTE: We DO NOT recommend using a garden hose to clean
the generator. Water can enter the engine fuel system and cause
problems. In addition, if water entem the generator through
coolingair slots,some of the water will be retained in voids and
cracks of the rotor and stator winding insulation. Water and dirt
buildup on the generator internal windings will eventually de-
crease the insulationresistanceof these windings.
TO CLEAN THE GENERATOR:
• Use a damp cloth to wipe exterior surfaces clean.
• Use a soft, bristle brush 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 opening
on the generator. These openings must be kept clean
and unobstructed.
CAUTION: NEVER INSERT ANY OBJECT OR
TOOL THROUGH THE AIR COOLING SLOTS, EVEN
IF THE ENGINE IS NOT RUNNING. DAMAGE TO
THE UNIT OR PERSONAL INJURY MAY RESULT.
ENGINE MAINTENANCE
CHECKING OIL LEVEL
See OPERATION sectionon Page 4 for informationon checking
oil level. Oil level should be checked before each use or at least
every eight hours of operation. Keep oil level maintained.
CHANGING 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
dirty or dusty conditions, or in extremely hot weather,
change oil more often.
J ,_ CAUTION: DISCONNECT SPARK PLUG WIRE
FROM SPARK PLUG AND KEEP IT AWAY FROM
SPARK PLUG. DO THIS EVERYTIME YOU PER-
FORM ANY MAINTENANCE ON THE ENGINE OR
THE GENERATOR,
Change oil while engine is still warm from running, as
follows:
• Clean area around oil drain plug, remove plug (Fig. 11)
and drain oil completely into a suitable container.
OIL FILTER

FIG. 11
• When oil has drained, install and tighten oil drain plug.
• Remove oil fill plug and insert a clean fill funnel into
plug opening. Fill engine crankcase with recom-
mended oil until oil level is at point of overflowing. Do
not overfill above the point of overflowing. About 21
ounces (620ml) is required. POUR SLOWLY.
• When engine crankcase is filled to proper level. Install
and tighten oil fill plug.
Replace Oil Filter: Replace the engine oil filter after first
8 hours of operation, every 50 operating hours thereafter.
• Turn oil filter counterclockwise to remove (Figure 11).
• Coat gasket of new filter with engine oil.
• Turn the new filter clockwise until its gasket contacts
tightly with the filter adaptor. Then tighten by hand an
additional 3/4 to one turn.
RETORQUE HEAD BOLTS
After 50 hours of operation, retorque the head bolts for the
GN engine to 4.0 kg/m (29 foot-pounds).
• The torque sequence is A, B, C, D, E (star pattern).
See Fig 12.
