Before clearing a blockage.
If your mower starts to vibrate
abnormally (check immediately).
•
Do not use solvents or cleaning fluids to
clean your mower - use a blunt scraper
to remove grass and dirt.
•
After striking a foreign object, inspect
your mower for damage and make
repairs as necessary.
•
•
Always disconnect from the electrical
supply before cleaning.
•
Never run your mower whilst lying on its
side or attempt to stop the blade -
always allow it to stop on its own.
Do not operate your mower if any parts
are defective; discard all defective parts
and fit new parts before use.
•
•
•
Do not put hands or feet near or under
rotating parts.
•
•
Keep all nuts, bolts and screws tight to
be sure your mower is in a safe working
condition.
Keep clear of discharge openings at all
times.
Use only Black & Decker recommended
replacement parts and accessories.

•
•
•
•
•
Use your mower only in daylight or good
artificial light.
Double insulation
Do not pull your mower towards you or
walk backwards when in operation.
Your mower is double insulated.
This means that all external metal parts are
electrically isolated from the power supply.
This is achieved by placing an extra
insulation barrier between the electrical and
mechanical parts. Double insulation means
greater electrical safety and obviates the
necessity of having your mower earthed.
Do not cross gravel paths or roads whilst
the tines are rotating.
Always be sure of your footing,
particularly on slopes.
Always cut across the face of slopes, never
up and down. Exercise extreme caution
when changing direction on slopes.
•
•
Do not cut excessively steep slopes and
always wear non-slip footwear.

(park) positions and one operating position.
Positions 1 and 3 in Fig. E are the storage
(park) positions and F is the operating range.
Note: If the plastic blade cutting system is
fitted then it will be necessary to grip the
blade carrier (25) firmly to prevent it from
turning (Fig. F).
For storage purposes, the handle assembly
can be set to position 2 or 3, as follows:
•
Remove the blade nut, white washer
(26) (if supplied), spacers and blade

Carrying your mower
Disconnect your mower from the mains.
Remove the grassbox (if fitted), lower the handle to
the flat “park” position and then, holding one handle
near the pivot block and carry with the blade pointing
away from you.
The following procedure assumes that the
steel blade is fitted. If the plastic blade
cutting system is fitted then take blade to
mean blade carrier. The blade carrier (25) is
shown in Fig. F.
How to use your mower (Fig. H & J)
The procedure for adjusting the height of cut
is as follows:
Observe all the relevant warnings when
using your mower.
!
Caution: The plastic blade cutting system has
been designed to maintain lawns at a fixed
length, not for cutting long grass. We strongly
recommend that you use the steel blade to
cut your grass to the required length, then
use the plastic blade to maintain that length.
We recommend the directional method of
operation to obtain maximum cutting
performance from your mower and to reduce
the risk of the trailing extension lead from
entering the cutting path.

•
Place the bulk of the extension cable
on the lawn close to the starting point
(Fig. Ja position 1).
Note: To obtain the best results cut your
lawn or grassed area regularly and do not
cut when the grass is wet.
Your switch box incorporates a cable
restraint. To fix the cable to the restraint,
proceed as follows:
Changing to the plastic blade system
(Fig. K)
•
Bring the socket end of the extension
cable from behind and connect it to your
mower plug.
A plastic cutter blade system can be
purchased as an accessory for your mower.
This system comprises a blade carrier and a
number of blades.
•
•
Form a loop on your extension cable
close to the switchbox.
H
The steel blade is designed to give a fine
finish in long or tough grass.
Push the loop through the slot from
the opposite side of the restraint hook,
position the loop over the hook and
pull the cable back through the slot.
Your cable will now be restrained.
The plastic blade system can be used for
safer cutting in normal conditions. It should
not be used to cut tough or long grass as
the plastic blades are not designed for
this purpose.
•
The extension cable should now fall
away from your mower and behind the
operator, ready for use.
To remove the steel blade and to fit the
plastic blade system, proceed as follows:
Warning! Do not attempt to operate your
mower with one hand - you must guide it
with both hands.
Warning! Disconnect your mower from the
!
electrical supply before fitting the plastic
blade system.
!
•
Lift the handle up to release it from the
park position.
•
Remove the steel blade as described in
“Height of cut adjustment” but retain the
two thicker spacers and the nut.
•
Tilt the unit slightly on its side to reduce
the risk of lawn damage whilst starting,
depress the safety lock-off button (15)
on the switchbox (13) (Fig. D), and whilst
still depressed pull the switch lever (14)
towards you. Your mower will start, and
you can now allow it to return to its
proper cutting position, and commence
cutting.
•
If you wish to alter the height of cut
whilst fitting the plastic blade system
then follow the instructions given in
“Height of cut adjustment”.
•
•
Using a damp cloth, clean the contact
faces of the spacer rings, removing any
grass or debris.
•
Proceed down the cutting area as
shown in Fig. Ja, working from position
1 towards position 2 and, on reaching
position 2, turn to the right and proceed
towards position 3. Continue to the end
of the cutting area, turn to the left, and
proceed towards position 4. Continue in
the same manner as shown in Fig. Ja,
always working away from the cable.
Do not adopt the method shown in
Fig. Jb, working towards the cable,
as this can be dangerous.
Fit any spacers necessary to give the
correct height adjustment, fit the blade
carrier (25) on to the motor spindle with
the ribbed face towards the impeller,
fit any remaining spacers and fit the nut.
Use a cloth or wear a heavy duty glove
to prevent the blade carrier from turning
and tighten the nut with the spanner
provided.
J
Note: Instructions on how to fit the blade
carrier to your mower are also given on a
label on the blade carrier.
Your mower will continue to operate whilst
you are pressing the switch lever. If you
release it for any reason you will not be able
to press it again until you have pressed the
safety lock-off switch on the switch box.
This feature prevents accidental restart.
•
Attach two plastic blades (30) to the
blade carrier (25), by placing one blade
on each blade pivot (31) and pull the
blades outwards so that they are locked
into position.

Overload protection
Your mower is fitted with overload protection.
The reset button (33) can be found on the switch box
(Fig. A).
ENGLISH
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 mower.
Fitting a new blade
Observe all the relevant warnings before
changing blades.
!
Details on the fitment of new steel blades are
given in “Cut height adjustment”. Details on
the fitment of new plastic blades are given in
“Changing to the plastic blade system”.
When this occurs, release the switch and wait for
2 to 3 minutes to allow the motor to cool, then press
the reset button (33) and restart by operating the
switch lever.
If the cut-out operates again within 10 minutes you
should increase the height of cut (see “Height of cut
adjustment”) and walk more slowly.
Handy hints
•
Before starting your mower on grass always tilt it
to one side slightly and allow it to run up to
maximum speed before commencing to cut the
grass. This will maximise the hover effect and will
prevent the blades from digging into the grass.
Severe overloading may result in a longer delay on
restarting. In such cases, after resetting, you should
allow the motor to cool.
•
On long grass, above 10cm (4 inches), use two
cuts to get a close finish. We recommend that
the first cut should be taken with the blade set at
maximum height of cut and the second taken
with it set at medium or close. This will prove to
be easier and give a better overall finish to
your lawn.
Blade maintenance
Steel blades
The steel blade is designed to give a fine
finish in long or tough grass. The blade will
continue to cut even when it has become
blunt or burred. There is no need for it to be
razor sharp.
Care and maintenance
If, however, because of damage or wear the
cutting performance deteriorates, then your
mower may require a new blade, or at least
the existing blade to be sharpened.
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”.
We recommend that the steel blade is
sharpened or a new blade fitted at the
beginning of each season.
Warning! Do not use a cable which
shows signs of damage. Fit a new cable
completely - do not make any permanent or
temporary repairs.
!
Plastic blades
Plastic blades will wear during use. This type
of blade cannot be sharpened and should be
discarded and new blades fitted when worn.
•
Always keep your mower clean and free
from grass cuttings, especially the
underside of the cutter cover and the air
vents.
Note: Plastic blades should be replaced in
pairs, not singly.
•
•
Check all electrical cables at regular
intervals, looking for signs of wear,
abrasion or other damage.
A number of spare blades are supplied with
the plastic blade cutting system when
purchased separately.
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 or the
spanner supplied.
Replacement blades are available from
Black & Decker service agents.
Warning! When fitting a new blade use only
the Black & Decker replacement part
specified for your mower - do not attempt to
fit any other blade.
!
•
•
Remove grass cuttings from the slot
between the pivot block flanges.
Clean all plastic components with a
damp cloth.
