WARNING DANGER

Do not perform maintenance on the engine or muffler until engine

and muffler are completely cool, otherwise serious personal injury

may occur.

SPARK PLUG

Level 2.

Tools required: 3/4 in. Spark Plug deep socket, Feeler gauge (preferably

a wire gauge),

Parts Required: 90065 REPOWER

Tune-Up Kit

1. Remove spark plug and check for fouling, worn and rounded

center electrode.

2. Clean the plug or replace with a new one. DO NOT sand blast to

clean. Remaining sand will damage engine.

3. Adjust spark plug gap by bending outer electrode.

4. Tighten spark plug to 145-155 kg/cm (125-135 in. lb.).

COOLING SYSTEMS CLEANING

Level 2.

Tools required: 25-50 mm (1-2 in.) medium bristle brush, 3 mm Hex

Wrench, Cross Head Screwdriver.

Parts Required: None, if you are careful.

IMPORTANT

To maintain proper engine operating temperatures, cooling air must

pass freely through the cylinder fin area. This flow of air carries

combustion heat away from the engine.

Overheating and engine seizure can occur when:

• Air intakes are blocked, preventing cooling air from reaching the

cylinder.

• Dust and grass build up on the outside of the cylinder. This build up

insulates the engine and prevents the heat from leaving.

Removal of cooling passage blockages or cleaning of cooling fins is

considered “Normal Maintenance”. Any failure attributed to lack of

maintenance is not warranted.
