MAINTENANCE

Spark Plug

Level 2.

Parts Required: REPOWERTM Tune-Up Kit

Use only NGK BPM-6Y spark plug (BPMR-6Y in Canada) otherwise severe engine damage may occur.

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

0.65mm

(0.026 in.)

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 150-170 kgf • cm (130-150 in • lbf).

Cooling System

Level 2.

Parts Required: None if you are careful.

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. Brush accumulated debris from intake grill between backpack frame and blower housing.
