MAINTENANCE PB-265LN
Spark Plug
Level 2.
Use only NGK BPM-8Y spark plug (BPMR-8Y 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 and Cylinder Fins
1. Remove accumulated debris from intake grill between
backpack frame and blower housing.
2. Disconnect spark plug lead from spark plug.
3. Remove spark plug.
4. Remove engine cover.
5. Loosely install spark plug to keep dirt out of cylinder.
6. Clean cylinder fins to allow cooling air to pass freely.
7. Reassemble parts in reverse order.
Parts Required: REPOWER TM Tune-Up Kit
Parts Required: None if you are careful.
