MAINTENANCE

Cutter

WARNING! Always wear heavy-duty gloves

!when repairing the cutting attachment. The blades are very sharp and can easily cause cuts.

It is important to have a sharp and correctly balanced cutter. Loosen the bolt holding the cutter and leave the cutter at a service workshop at least once a year for grinding and balancing. An appropriate time to do this is after the mowing season has finished.

If the cutter or cutter bracket need to be changed you must replace the cutter bolt, washer and cup spring at the same time.

The bolt should be tightened with a torque of 45-60 Nm when you fit the cutter again. See instructions under the heading Assembly.

If the cutter hits foreign objects such as stones, roots or the like the cutter will slip against the cutter bracket. This may mean that the contact surface of the cutter bracket appears slightly worn, which is completely normal. This is a safety device, which reduces the risk of the engine shaft becoming bent.

Changing the oil

The engine oil should be changed each year and every 25 working hours.

When changing the oil proceed as follows::

•Disconnect the HT lead from the spark plug.

•Empty the fuel tank

•Close the fuel tap.

•Unscrew the oil filler cap.

•Drain the oil by tipping the engine so that the oil runs out through the filler pipe.

•Ask where you can dispose of surplus engine oil at your local petrol station.

•Fill with new engine oil of a good quality. See the Technical data section.

•Check the oil level with the dipstick on the oil filler cap. The oil filler cap must be completely screwed down to give a correct picture of the oil level.

If the oil level is low, fill using engine oil up to the upper level on the dipstick.

•Screw on the oil filler cap.

Lubrication of the cutting height adjustment

The mechanical parts of the cutting height system should be lubricated regularly (once a week). Lubricate the cutting height system with a few drops of oil.
