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.
To make draining the oil easier, a 6" length of vinyl (PVC) hose
with an inside diameter of 1.25" (32mm) may 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.
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.

CHANGING THE SPARK PLUG
Replace the spark plug each year, regardless of how many hours
the generator has been run. Use a NGK BPR6ES that has be
gapped to .030" (.76mm). To replace the spark plug:
1. Remove the spark plug cover on the top right side of the
generator, just below the handle (Figure 12).
2. Carefully pull the spark plug lead from the spark plug. Use a
socket wrench to remove the spark plug.
3. Install the new spark plug into the cylinder head. Tighten the
spark plug to 15 ft/lb.
4. Replace the spark plug lead, making sure it is fully seated.
5. Replace the spark plug cover.
