SECTION 7: MAINTENANCE AND REPAIR INSTRUCTIONS

Replacing the Spark Plug

Use a Champion RDJ7Y spark plug (or equivalent). The correct air gap is 0.020 inch (0.5 mm). Remove the plug after every 25 hours of operation and check its condition.

1.Stop the engine and allow it to cool. Grasp the plug wire firmly and pull it from the spark plug.

2.Clean around the spark plug. Remove the spark plug from the cylinder head by turning a 5/8 in. socket counterclockwise.

3.Replace cracked, fouled or dirty spark plug. Set the air gap at 0.020 in. (0.5 mm) using a feeler gauge. See Figure 34.

CAUTION: Do not sand blast, scrape or clean electrodes. Grit in the engine could damage the cylinder.

4.Install a correctly-gapped spark plug in the cylinder head. Tighten by turning the 5/8 inch socket clockwise until snug.

If using a torque wrench torque to:

110-120 in.•lb. (12.3-13.5 N•m).

Do not over tighten.

Long Term Storage

If the unit will be stored for an extended time, use the following storage procedure:

1.Drain all fuel from the fuel tank into a container with the same 2-cycle fuel mixture. Do not use fuel that has been stored for more than 60 days. Dispose of the old fuel/oil mix in accordance to Federal, State, and Local regulations.

2.Start the engine and allow it to run until it stalls. This ensures that all fuel has been drained from the carburetor.

3.Allow the engine to cool. Remove the spark plug and put 1 oz. (30 ml) of any high quality motor oil or 2- cycle oil into the cylinder. Pull the starter rope slowly to distribute the oil. Reinstall the spark plug.

NOTE: Remove the spark plug and drain all of the oil from the cylinder before attempting to start the trimmer after storage.

4.Thoroughly clean the unit and inspect for any loose or damaged parts. Repair or replace damaged parts and tighten loose screws, nuts or bolts. The unit is ready for storage.
