Cleaning Air Filter
Using compressed air, blow the dust from both elements and the Filter Base on the Engine.
If the Filter Elements cannot be cleaned, wash the foam element with mild soap and water,
and dry. Purchase a new paper Filter Element if necessary. Reinstall Filter Elements, Air
Filter Housing, and Nut. See photo below, left.
Cleaning and Replacing Spark Plug
1. Pull off the Spark Plug Cable.
2. Using a socket wrench (not supplied), carefully unscrew the Spark Plug.
Wait for the Engine to cool to avoid burning hands.
3. Clean Spark Plug with a steel brush. If the insulator is damaged, replace Spark Plug.
Caution: Using other than the recommended Spark Plug replacement type can damage
the Engine (see Specifications on page 2).
4. Measure the Spark Plug electrode gap with a feeler gauge (not supplied). See
illustration above, left.
It should be set to 0.030” (0.76 mm). If adjustment is necessary, bend the side
electrode carefully, then re-measure. If Spark Plug Gasket is damaged, replace it.
5. Replace Spark Plug by hand for the first few turns, then tighten with the socket wrench
completely. Securely tighten. A Spark Plug with a new Gasket requires 1/2 more turns
to tighten than the used Gasket which requires 1/8 to 1/4 turns to tighten.
Changing Oil
1. Run the Engine for five minutes to warm up the oil, then shut off the Engine.
2. Place a drain pan under the Drain Plug. (Drain plug screw is located under the
Engine.)
3. Remove the Dip Stick and unscrew the Drain Plug.
4. Allow all the oil to drain out into the pan. Pour the used oil into a container with a lid.
Deliver used oil to a recycling center. Do not dump oil into the earth or storm drain.
5. Replace Drain Plug and securely tighten.
6. Add 1/2 quart of 10W 30 motor oil through a siphon into the Dip Stick fill hole. Fill until
the oil reaches the Upper Level line of the fill hole.
7. Replace the Dip Stick, being careful not to strip its plastic threads.
