B Yellow = the battery's power has reduced. Be-
tween 5% and 30% remains.
C Red = 5% or less of the battery power remains.
The machine will begin to beep and will switch
itself off automatically. Stop mowing and re-
charge the battery once it has cooled down (after
about 30 minutes). Do not use the mower again
until the battery is fully charged.
Important: do not allow the battery power to com-
pletely run down as this may damage the battery and
shorten its operational life.

MOWING TIPS

For best cutting results and to ensure that the bat-
tery lasts as long as possible, the following rules
should be followed:
• Drive the mower at a slow and even pace
• Try to avoid excessive starting and stopping, as
this draws a lot of current.
• Make sure that the motor is running at full speed
at all times when mowing.
• Mow regularly and often, especially when the
grass is growing quickly. Do not mow more than
a third of the total height of the grass during one
mowing session.
• Always use a sharp blade.
• Do not use the mower when it is raining or when
the grass is wet.
• Make sure that the underside of the cutting deck
is kept clean.

MAINTENANCE

Take out the safety key and remove the
battery before any type of maintenance is
carried out.
CLEANING
The mower should be cleaned after each use. Use a
moistened cloth or sponge and a mild soap solution.
Do not clean with water or solvents. Remove all
grass clippings which might have gathered on the
underside of the deck and in the ejector.
The grass collector, although not the mower it-
self, can be cleaned with water. Grass collection ef-
ficiency is reduced if the holes are blocked.

CHANGING THE BLADE

Check, before and after each use, that the
blade is tightly fixed and that it is not
damaged. A bent or damaged blade
should immediately be replaced. Use pro-
tective gloves to avoid cutting injuries.
Blunt and/or damaged blades tear off the grass and
make the lawn look ugly after mowing. New, well-
sharpened blades cut off the grass and ensure that it
looks green and fresh after it has been mown.
Remove the battery. Put the accompanying wrench
(36 mm) on the hexagon holder. Loosen the blade
nut with an adjustable wrench or another type of
fixed wrench (19 mm) (fig. 10). Turn the blade nut
in an anti-clockwise direction in order to remove the
blade.
Fit the new blade and refit all the other parts exactly
as they were before they were dismantled, see fig.
10. Tighten the blade nut fully.

SHARPENING THE BLADE

Water grinding with whetstone or a grinding stone
should be used to sharpen the blade.
For safety reasons, the blade should not be sharp-
ened on an emery wheel. Too high a temperature
can result in the blade becoming brittle.
If the blade is sharpened, it must be bal-
anced afterwards to avoid vibration
damage (fig. 11).
