6.2.1 Fault symptom during Mowing
Symptom (mowing) Cause Action
Uneven mowing results The Automower
®
works too few hours per
day.
Increase the working hours.
Working area too large. Try to limit the working area or extend the working
time.
Dull blades. Replace all the blade units so that the rotating parts
are balanced.
Long grass in relation to the set cutting
height.
Increase the cutting height and then successively
lower.
The mower's various starting areas are
not being used correctly.
Run the mower in the installation using the starting
areas that are available under Installation - Follow
loop - Follow loop out.
Accumulation of grass by the blade disc
or around the motor shaft.
Check that the skid plate and the blade disc rotate
freely and easily in relation to each other. If not, the
skid plate and perhaps the blade disc must be
removed and the grass and foreign objects removed.
The Automower
®
works at
the wrong time.
The clock on the Automower
®
needs to be
set.
Set the clock.
The start and stop times for mowing are
incorrect.
Adjust the start and stop time setting for mowing. The
battery in the control box may need to be replaced,
see page 96.
The Automower
®
vibrates Unbalanced blade disc or damaged
blades.
Inspect the blade and screws and replace them if
necessary.
The mower mows for
shorter periods than usual
between charges
Grass or a foreign object is blocking the
blade disc or skid plate. The cause may
also be low battery capacity.
Dismantle and clean the skid plate and blade disc.
Perform a battery test to determine the battery's
capacity.
Both the mowing and
charging times are shorter
than usual
This behaviour is normal in high
temperatures (gradually increasing above
25 °C). The cause may also be low
battery capacity.
Perform a battery test to determine the battery's
capacity.
Automower
®
runs at an
angle or in an arc.
The tilt sensor is calibrated incorrectly.
The mower believes it is climbing a slope
and tries to compensate for this.
Calibrate the tilt sensor by selecting Tools - Special
settings - Calibrate tilt sensor (shortcut 5-6-3)
The tilt sensor is defective. Replace the control box, see page 92 about
replacement.
Grass has accumulated on one of the
drive wheels.
To keep the drive wheels clean and thus increase
traction, use wheel brushes (505 13 27-01).
