Level 2.

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

a wire gauge),

Parts Required: Spark Plug, NGK BPM-7Y, P/N 99944500071

1. Remove spark plug (LN models; spark plug cover and 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.).

5. Install spark plug cover (LN models).

IMPORTANT

Always reinstall spark plug cover on LN models, otherwise engine

cooling is greatly reduced, and will cause engine failure.

COOLING SYSTEMS CLEANING

Level 3.

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

Cross Head Screwdriver, Pointed Wood Stick.

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.

Cleaning Grill

1. Remove accumulated debris from intake grill between backpack

frame and blower housing.
