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
1
occurs first. A spark plug wrench is available from any authorised
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.
