MAINTENANCE

Spark Plug Service

 

Use only an approved spark tester (1) to check for a spark as shown in

 

the diagram.

1

Replace the spark plug every 100 hours or every season, whichever

 

occurs first. A spark plug wrench is available from any authorised

 

Honda service dealer.

Check the spark plug gap with a feeler gauge and set at 0.7 - 0.8mm.

Keeping Engine Clean

Remove all grass and debris from the engine including the exhaust/exhaust guard, the air ways in the top cowl and the surround- ing deck areas on a daily basis after use. Never spray the engine with water during cleaning. Water can contaminate the fuel. Always clean with a brush or compressed air.

Grass and debris may clog the engine’s air cooling system especially after prolonged operation while cutting tall, dry grass. The internal cool- ing fins and surfaces may require cleaning to prevent overheating and engine damage. We recommend that this service be carried out by an authorised dealer.
