Maintenance

Check the safety system

The machine is equipped with a safety system that prevents starting or driving under the following conditions.

The engine must only be possible to start when the following conditions are met:

•The cutting unit is disengaged.

•The parking brake is applied.

The engine must stop under any of the following conditions:

•The cutting unit is activated and the driver stands up.

•The cutting unit is disengaged, the parking brake is not applied and the driver stands up.

When the safety circuit has stopped the drive to the cutting unit, the control must be pushed and pulled out again to start the blades.

Check daily to ensure that the safety system works by attempting to start the engine when one of the conditions above is not met. Change the conditions and try again.

Replacing the light bulbs

For information about the bulb type, see Technical Data.

1Unscrew the four screws holding the cover on the power servo housing.

2 Unscrew the two screws holding the lamp insert.

3Lift out the lamp insert.

4Disconnect the cables from the bulbs.

5Lift out the bulbs from the insert.

6Insert the new bulbs. Make sure you use your thumb to support the front.

7Reﬁt the cables, lamp insert and the cover on the power servo housing.

Main fuse

The machine has a high-power safety fuse located in a box on the top of the battery plus terminal.

A feeder fuse for the electrical connection box is located on a bracket near the battery.

Other fuses are in the electrical connection box behind right side cover.

A blown fuse is indicated by a burnt connector. Pull the fuse from the holder when replacing.

The fuse is there to protect the electrical system.

Do not use any other type of fuse when replacing. If it blows again shortly after replacement, it is due to a short circuit, which must be ﬁxed before the machine can be put into operation again.

Checking the tyre pressure

The tyre pressure should be 1.5 bar/150 kPa/22 PSI for all wheels

The air pressure in the cutting unit pivot wheel must be 150 kPa/1.5 bar/22 psi.

IMPORTANT INFORMATION

Different tyre pressures on the front tyres will result in the blades cutting the grass at different heights.
