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
n
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 upwards 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
n
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.
n
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.
NOTE:
To make draining the oil easier, a 6” length of vinyl (PVC) hose
with an inside diameter of 1.25” (32mm) any be placed over the
drain lip.
3. Tip the generator upright once the oil has finished draining.
Replace the engine oil with the proper grade called out in Section
“ADDING ENGINE OIL”, then replace the drain plug.
CHANGING THE FUEL FILTER
Locate the fuel filter, just below the engine intake housing (Figure 11).
Make sure the Fuel Shutoff is in the “OFF” (O) position.
1. Remove the pinch clamps securing the fuel filter. Pull the hoses
free.
n
Wipe up any fuel spills immediately! Do not
smoke or replace the fuel filter near sparks or
open flame!
2. Replace the used filter with a new one. Push the fuel hoses onto
the barbed filter fittings until they are seated completely.
3. Replace the clamps, making sure they are seated on the fittings.
