finish in long or tough grass.
If, however, because of damage or wear the
cutting performance deteriorates, then the
mower may require a new blade, or at least
the existing blade to be sharpened.
6
We recommend that the steel blade is
sharpened or a new blade fitted at the
beginning of the season.
ENGLISH
Replacement blades A6157 are available from
Black & Decker dealers and service centres.
Warning! When fitting a new blade use only
the Black & Decker replacement part
specified for your machine - do not attempt
to fit any other blade.
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.
Fitting new blade (Fig. G)
Observe all the relevant warnings before
changing the blade.
Warning! Remove safety key before
changing the blade.
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.
Turn your machine over on its side so
that the underside of the cutter deck is
exposed.
G1•
If the cut-out operates again within 10 minutes, you
should increase the height of cut (see “Height of
cut adjustment”).
•
•
Wear gloves to protect hands.
Severe overloading may result in a longer delay on
restarting. In such cases, after resetting, you should
allow the motor to cool.
Using a cloth placed over the blade or
heavy duty gloves to protect your hands,
grip the blade and, using the spanner
provided, loosen and remove the nut
from the motor spindle. Turn the nut in an
anti-clockwise direction to loosen it.
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.
Remove nut (23), square washer (22),
clutch plate (21) and blade.
G2•
•
To replace blade ensure the cutting
edges of the blade are closest to the
ground and place blade onto the
combined mount.
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”.
Place the clutch plate over the shoulder
of the combined mount protruding
through the blade. Ensure to align the
inside edges with the outside edges of
the blade.
G3•
G4•
•
Place the square steel blade spacer on
the motor shaft aligning the inside flats
with the shaft and engaging the outside
edges with the plastic clutch plate.
Engage nut on shaft and turn it
clockwise to tighten.
•
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.
Ensure that removed parts are replaced
correctly before use, incorrect assembly
may result in damage to your mower
and reduced cutting performance.
•
•
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.
Note: This unit is fitted with a clutch plate
(24), between the blade nut and the blade,
which must be assembled correctly at all
times. Damaged blade assembly parts must
be replaced before use.
