Air Filter Element Maintenance

1.Place a drain pan (not included) un- derneath the crankcase’s drain plug.

2.Remove the Dip Stick and Oil Drain Plug and, if possible, tilt the crank- case slightly to help drain the oil out. Recycle used oil.

3.Replace the Oil Drain Plug and gas- ket and tighten it.

4.Remove the cap from the Oil Fill Port.

Using a siphon, refill the oil to the proper level. Replace the cap on the Oil Fill Port.

5.Recheck the oil level, using the dip- stick. Add or remove oil if necessary. Do not operate the engine with too much or too little oil.

6.Inspect before operation.

1.Wipe off the air cleaner cover.

2.The air cleaner cover is held in place by a wing nut or clamps. Remove it.

3.Remove the air filter element.

4.Cleaning:

a.For “paper” filter elements:

To prevent injury from dust and debris, wear ANSI-approved safety goggles, NIOSH-approved dust mask/respirator, and heavy-duty work gloves. In a well-ventilated area away from bystanders, use pressurized air to blow dust out of the air filter from the side oppo- site the filter’s normal air flow (the “clean” side of the filter).

If this does not get the filter reason- ably clean, replace it.

b.For foam filter elements:

Wash the element in warm water

and mild detergent several times. Rinse. Squeeze out excess water and allow it to dry completely. Soak the filter in lightweight oil briefly, then squeeze out the excess oil.

4.Install the new filter or the cleaned filter. Secure the Air Cleaner Cover before use.

Spark Plug Maintenance

1.Disconnect spark plug wire from end of plug. Clean out debris from around spark plug.

2.Using a spark plug wrench, remove the spark plug.

3.Inspect the spark plug:

If the electrode is oily, clean it using a clean, dry rag.

If the electrode has deposits on it, polish it using emery paper.

If the white insulator is cracked or chipped, the spark plug needs to be replaced.

4.When installing a new spark plug, ad- just the plug’s gap to the specification on the Technical specification chart

(page 14). Do not pry against the electrode or the insulator, the spark plug can be damaged.

5.Install the new spark plug or the cleaned spark plug into the engine. Gasket-style: Finger-tighten until the gasket contacts the cylinder head, then about 1/2-2/3 turn more. Non-gasket-style: Finger-tighten until the plug contacts the head, then about 1/16 turn more.

6.Apply dielectric spark plug cap pro- tector to the end of the spark plug and reattach the wire securely.
