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.

servo housing.

Maintenance
5 Lift out the bulbs from the insert.
6 Insert the new bulbs. Make sure you use your thumb to
support the front.
7 Refit 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.
