MOWER MAINTENANCE
Spark Plug Service 
Use only Briggs & Stratton spark tester (1) to check for a spark as shown in the diagram.
Replace the spark plug every 100 hours or every season, whichever
occurs first. A spark plug wrench is available from any authorised 1 Briggs & Stratton service dealer.
Check the spark plug gap with a feeler gauge and set at 0.76mm.
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 recommended that this service be carried out by an authorised Briggs and Stratton dealer.
Grassbag
Remove grass debris from the grassbag immediately after use and check its condition for signs of damage.
To prevent accidents replace a damaged grassbag immediately.
