NOTE:
DO NOT use a garden hose to clean the generator. Water
can enter the engine fuel system and cause problems. In
addition, if water enters the generator through cooling air
slots, some water will be retained in voids and crevices of the
rotor and stator winding insulation. Water and dirt buildup on
the generator internal windings will eventually decrease the
insulation resistance of these windings.

CLEANING THE GENERATOR
1. Use a damp cloth to wipe exterior surfaces clean.
2. A soft, bristle brush may be used to loosen caked on dirt, oil,
etc.
3. A vacuum cleaner may be used to pick up loose dirt and
debris.
4. 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.
5. Inspect the vent hoses on the left side of the generator. Make
sure the hoses protrude through the slots below the door and
that the ends are open and free of debris.
ENGINE MAINTENANCE
NOTE:
Only work on a generator that has cooled completely.
Inspect the oil level and air filter condition each time you are going
to use the generator. To check the air filter and oil level the left side
service cover must be removed; use a screwdriver to loosen the
screw securing the cover and remove.
The air filter is located behind a cover for the air box (Figure 10).
Push the tab on the bottom of the air box up wards to release the
cover. To service the air cleaner:
1. Remove the air cleaner. Tap the element to shake loose any
large particles.
2. Wash the element in soapy water. Squeeze the filter dry in
clean cloth (DO NOT TWIST).
3. Soak the filter element in clean engine oil. Squeeze the excess
oil from the filter, leaving a light coating.
4. Clean air cleaner housing and cover before re-installing the
filter element.

CHANGING THE ENGINE OIL
Hot oil may cause burns. Allow engine to cool
entirely before draining oil. Avoid prolonged
or repeated skin exposure with used oil.
Thoroughly wash exposed areas with soap.
Change the engine oil after the first five (5) hours of operation.
Change the engine oil every 100 hours thereafter. To change the
engine oil:
1. Run the generator briefly to warm the engine oil; this also
loosens any engine deposits and makes the used oil flow
easier.
Change the oil only when the fuel tank is low
or nearly empty. Tipping the generator with a
full fuel tank may cause fuel leakage.
2. Place the generator over a drain pan and remove the drain
plug. Tip the generator on its side to drain the used oil from
the crankcase.
