Overload protection

Your machine is fitted with overload protection.
If you work too quickly in long grass, or in heavy
cutting conditions, you may overload the motor.
This will be indicated by a significant drop in speed,
and eventually, the overload protection will operate.
This is not a fault but a safety device to protect
your machine.
When this occurs, remove the safety key and wait for
1 to 2 minutes to allow to cool, clear any blockage
ensuring the blade is free to rotate. To restart,
replace the safety key and operate the switch lever.
If the cut-out operates again within 10 minutes, you
should increase the height of cut (see "Height of
cut adjustment").
Severe overloading may result in a longer delay on
restarting. In such cases, after resetting, you should
allow the motor to cool.
To obtain the best results:
•
Cut the grass regularly.
•
Do not cut wet grass.
•
When the grass is longer than 10cm (4 inches),
it is advisable to go over the lawn on a high cut
setting and then finish using a lower setting.

Care and maintenance

The advice given in this section covers the general
care and maintenance of the main body of your
mower. Advice relating to the blades is given in
"Maintenance of blades". Advice relating to the
maintenance and storage of the battery is given in
"Battery information".
•
Always keep your machine clean and free from
grass cuttings, especially the underside of the
cutter deck and the air vents.
•
At the end of each cutting session we
recommend that the build up of grass on the
underside of the cutter cover is removed using a
blunt scraper, the spanner included with this
mower may be used for this purpose.
•
Clean all plastic components with a damp cloth.
•
Caution! Do not use solvents or cleaning fluids
as these may damage the plastic components of
your mower.
