Using a cloth placed over the blade or
heavy duty gloves to protect your
hands, grip the blade and, using a
spanner, loosen and remove the nut
from the motor spindle. Turn the nut in
an anti-clockwise direction to loosen it.
The blade can now be replaced and
the washer and nut reassembled.
Note: Some mowers are fitted with a clutch
washer, between the blade nut and the blade,
which must be reassembled at all times.
Overload protection (Fig. H)
Your machine is fitted with overload
protection. If you work too quickly in
long grass, or in heavy conditions, you
may overload the motor. If this occurs,
the safety key fuse will blow, causing the
machine to stop.
This is not a fault of the machine but a
safety device to protect your machine.
When this occurs, remove the safety key
and inspect the fuse link. If link is broken,
the fuse has blown and needs to be
replaced with a new fuse. One of which is
supplied as a spare in your parts pack.
Alternatively, you can purchase a new key
from any Black & Decker service centre.
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
