container.
• Refi ll with new oil of the recommended SAE viscosity
grade. Refer to 'Assembling the Mower Before First Use'

Air Cleaner Service

A dirty air fi lter will restrict the air fl ow to the carburettor,
reducing engine performance. If you operate the engine in
very dusty areas, clean the air fi lter more often than specifi ed
in the MAINTENANCE SCHEDULE.
The air cleaner system uses a pleated fi lter.
Servicing instructions:
• Open the cover (1).
• Remove the fi lter (2).
• To loosen debris, gently tap the fi lter on a hard surface.
Do not oil the cartridge.
Do not use petroleum solvents.
Do not use pressurised air.
If the fi lter is excessively dirty, replace with a new fi lter.
• Install the fi lter (2).

(Refer fi g. 20)
Operating the engine without an air fi lter, or a damaged air
fi lter, will allow dirt to enter the engine, causing rapid engine
wear. This type of damage is not covered by the limited
warranty.

Spark Plug Service

Use only Briggs & Stratton (Part number 19368) spark tester (1)
to check for a spark as shown in the diagram.
(Refer fi g. 21)
Replace the spark plug every 100 hours or every season,
whichever occurs fi rst. 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 0.51 mm.
