Check the oil level daily before starting the engine and ensure that the
correct oil level is maintained. Refer to-‘Before Starting the Mower’
for oil checking and filling instructions.
Change the engine oil after the first 5 hours of operation and thereafter
according to the ‘Maintenance Schedule’:-
1. Drain fuel by running the engine until the fuel tank is empty.
2. Remove the spark plug lead.
3. Allow the engine to cool.
4. Drain the oil while the engine is warm.(Not hot)
5. Tip the mower over on to its left hand side thus ensuring that
the air cleaner is kept uppermost to prevent engine damage.
6. Remove the oil filler dipstick and drain the oil into a suitable
container.
7. Refill with new oil of the recommended SAE viscosity grade.
(Refer to-‘Before Starting the Mower’)
