MAINTENANCE
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
6. Remove the oil filler dipstick and drain the oil into a suitable con-
tainer.
7. Refill with new oil of the recommended SAE viscosity grade.
(Refer to-'Before Starting the Mower')
Refer to the Maintenance Schedule at the end of this section and en-
sure that the recommendations are followed. More frequent service is
required when operating in adverse conditions.
- Gain access to the pre-cleaner (3) and cartridge (4) by loosening
screw (1) and cover (2).
- To service the pre-cleaner, carefully remove and wash in a solution
of liquid detergent and water. Allow to air dry thoroughly before
replacing.
- Clean the cartridge by tapping gently on a flat surface. If very dirty,
replace or wash in a solution of non-foaming detergent and warm
water. Rinse thoroughly with running water from the mesh side until
the water is clear. Allow the cartridge to stand and air dry thoroughly
before replacing. Do not use petroleum solvents during cleaning as this
will cause the cartridge to deteriorate. Do not use pressurised air as this
may damage the cartridge. Do not oil the cartridge.
- After servicing, install the pre-cleaner and cartridge in the cover. In-
sert the tabs on the bottom of the cover into the slots in the bottom of
the base (5). Tilt the cover upwards and securely tighten the screw to
the base.
to prevent engine damage.
