Spark Plug

Level 2.

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.

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.

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.
