Maintenance
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.
5. To order a new air filter, you will need part number 0H56810216.

3.5 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:
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.
1. 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.
2. 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.

3.6 CHANGING THE SPARK PLUG

Replace the spark plug each year, regardless of how many hours
the generator has been run. Use a NGK CR7HSA that has been
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 11).
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.

The engine exhaust muffler has a spark arrestor screen. Inspect
and clean the screen every 50 hours of operation or once each
year, whichever comes first.
Clean and inspect the spark arrestor as follows:
• Remove the screen retainer by removing the retainer clamp.
• Slide the spark arrestor screen out from the muffler outlet tube.
• Inspect screen and replace if torn, perforated or otherwise
damaged. Do NOT use a defective screen. If screen is not
damaged, clean with a commercial solvent.
• Replace the screen and retainer and secure with retainer clamp.
