MAINTENANCE

Adjust the belt by moving the ball-bearing up or down.

A new belt stretches and becomes longer, so adjust the belt again after a few hours of operation.

Screw on the belt cover and test run the machine.

Replacing and adjusting the centre belt

The centre belt runs between the engine shaft and the gearbox.

Remove the cutter. (only when replacing belt)

Unscrew the adjuster screws a few turns.

Replace the belt with a new one and tighten the adjustment screws a little. (only when replacing belt)

Adjust the belt by moving the gear forwards or backwards.

The belt should be stretched so that it can move 10mm in the centre. That corresponds to a pull of approx. 3 kg. Use a fishing scale to check.

Tighten the adjustment screws properly.

When changing the belt, refit the cutter with a torque of 45-60 Nm. See instructions under the heading Assembly.

Check the drive operation, as adjustment of the gear affects the belt tension in the gearbox.

Cleaning

Do not use a high pressure washer to clean the machine.

Never flush water directly on the engine.

When cleaning under the cutting hood, turn the machine with the spark plug upwards. Empty the fuel tank.

Trouble shooting

If the engine does not start, check the following:

Replace the fuel with new, clean fuel.

Check that the fuel valve is open.

Check that the engine brake works correctly and is undamaged.
