Changing the oil filter
To access the engine oil filter, follow the instructions under the
Changing the engine oil heading in section 1-4.
1 Remove the engine oil filter.
2 Before the new filter is fitted, its gasket must be coated
with fresh, clean oil.
3 Screw on the filter by hand until the gasket touches the oil
filter adapter.
4 Tighten a further 1/2 to 3/4 turns.
Engine oil pressure
• If the engine oil pressure drops below 0.1 to 0.2 kg/cm (1-
4 psi), an oil pressure switch shuts down the engine.
• If the engine oil level is below the mark on the dipstick, fill
with engine oil until the level reaches the "Full" mark. Try
starting the engine.
• If the problem persists, contact an authorised Briggs &
Stratton service agent.
Air filter
If the engine seems to lack power or does not run smoothly
this may be because the air filter is clogged. Inspect and
service the air filter at every oil change, after every 50 hours
of operation.
Muffler
If the muffler is corroded or is damaged in any other way, it
must be replaced because it may become a fire hazard and/
or cause injury.
Fuel filter
The fuel filter must be replaced if it becomes clogged and the
flow of fuel to the carburettor is blocked.
We recommend that the fuel filter is replaced every 250 hours
of operation or once a season.
Additional engine information
See the accompanying instruction manual from Briggs &
Stratton for more information on how to service the engine.
The manual also contains specific details on specifications,
service parts, engine guarantee, emissions compliance, etc.
