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.

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.
