The panel can still work despite one of the segments being
damaged, but then gives a lower capacity. This can mean that
the machine frequently stands still and charges, even on very
sunny days. Or the lawn mower can stand still and beep once
every 10 seconds, which is the night mode signal, despite it
being the middle of the day.
No objects should be placed on top the panels for these to give
maximum electrical energy. Panels should be cleaned using a
damp sponge and a soap solution/hand washing up detergent
when surfaces are dusty or dirty and during the pollen season
or with similar daily soiling.
Great care should be exercised when handling the panels due
to their low weight and fragility. This is especially important
when the lawn mower is turned upside down, e.g. when the
cutting height needs to be adjusted (see the diagram below).
WARNING!
The blades are extremely sharp. Always wear
protective gloves when working with the
blades or cutting disc.

TROUBLE SHOOTING
The cutting height can be adjusted variably between 30-60 mm.
Adjust the height by loosening the orange coloured knob and
move the entire cutting unit upwards or downwards in its
mountings.
The cutting disc is bolted to the cutting motor’s shaft and holds
3 blades thrown out by centrifugal force.
These blades are mounted in blade holders (coloured red) to
allow them to be easily attached to or dismantled from the
cutting disc. The design of the blade holders ensures that the
blades are well secured if a collision with small objects, e.g.
twigs on the lawn, should occur.
Motor and cutting disc
A 12V AC motor with controlled speed (max 2500 r/min) is used
as the cutting motor. The cables from the motor are connected
to connector X1 on the terminals 1-5 on the circuitboard in the
box. Registration of the motor speed is made by using a
tachometer which sends signals to the microprocessor on the
circuitboard in the box.
The speed measurement is made to “measure“ the length of the
grass (mowing resistance).
If the mowing resistance momentary exceeds the mean value
for the last few minutes the lawn mower can move in a spiral
pattern, to mow areas that have longer grass than average.
When the lower mower senses a drastic reduction in the
mowing resistance, or if an obstacle comes in its way, it returns
to its normal movement pattern.
