Mower Maintenance

Carburettor Adjustments

Should only be made by an authorised Briggs & Stratton dealer. Under no circumstances should the engine be adjusted to run at a speed in excess of that shown on the Declaration of Conformity.

Oil Service

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 right 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 viscos- ity grade. (Refer to-‘Before Starting the Mower’)

(Refer fig.22)

Air Cleaner Service

To service the air cleaner, loosen the knob (1) and re- move cover (2). Carefully remove the foam filter (3) and cartridge (4) together. Separate the foam filter (3) from the cartridge (4). (Refer fig.23)

If very dirty, replace.

-Do not use petroleum solvents.

-Do not use pressurised air.

-Do not oil the cartridge.

Spark Plug Service

Use only Briggs & Stratton (Part number 19368) spark tester (1) to check for a spark as shown in the diagram.

(Refer fig.24)

Replace the spark plug every 100 hours or every season, whichever occurs first. 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 0.50mm. (Refer fig.25)

Keeping Engine Clean

Remove all grass and debris from the engine including the exhaust/exhaust guard, the air ways in the top cowl and the surrounding deck areas on a daily basis after use. Never spray the engine with water during cleaning.

Water can contaminate the fuel. Always clean with a brush or compressed air. (Refer fig.26)

Grass and debris may clog the engine’s air cooling system especially after prolonged operation while cutting tall, dry grass. The internal cooling fins and surfaces may require cleaning to prevent overheating and engine damage. We recommended that this service be carried out by an authorised Hayter Service dealer.

Grassbag

Remove grass debris from the grassbag immediately after use and check its condition for signs of damage. To prevent accidents replace a damaged grassbag immediately. (Refer fig.27)

Deck Housing

Remove grass debris from the top and underside of the deck housing immediately after use. (Refer fig.28)

Fertilisers and top dressings are particularly corrosive. Thoroughly clean the mower deck immediately after use on treated grass and store well away from corrosive materials.
