Engine Detail

(Refer fi g.20)

Carburettor Adjustments

Never make adjustments to the carburettor or engine speed. The
carburettor was set at the factory to operate effi ciently under most
conditions. Do not tamper with the governor spring, linkages,
or other parts to change the engine speed. If any adjustments
are required contact a Briggs and Stratton Authorised Service
Centre for service.

Oil Service

Check the oil level daily before starting the engine and ensure
that the correct oil level is maintained. Refer to Assembling the
Mower Before First use for oil checking and fi lling instructions.
Change the engine oil after the fi rst fi ve hours of operation and
thereafter according to the Maintenance Schedule.
Drain the fuel by running the engine until the fuel tank is empty.
The oil must be drained from the top oil fi ll tube.
With engine off but still warm, disconnect the spark plug lead
and keep it away from the spark plug.
Remove the dipstick.
