Electric motors require specialist attention, so contact your local Hayter Authorised Service Dealer. If you do decide to make any adjustments yourself, ALWAYS disconnect the machine from the mains. Petrol engines are simpler to deal with, although again, if in doubt, consult your dealer.

ALWAYS remove the spark plug for maximum safety when working on your petrol engine.

Check and clean the air cleaner if you have been using it in dusty conditions, as a partly blocked cleaner will affect the running of the engine. Prolonged use will accelerate wear and tear in the engine. Change the oil according to engine manufacturers' recommendations.

Before use, make sure that the guards are in place and are in good condition and check the engine oil level.

Finally, check and lubricate the controls, wheel bearings, swinging guards, roller bearings and chains.
