Black & Decker’s policy is one of continuous
improvement to our products and, as such, we
reserve the right to change product specifications
without prior notice.
Double insulation
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.
Electrical safety (UK only)
Your mower should always be switched off
at the mains before disconnecting any plug
!
and socket connector or extension cables.
Fuse replacement
If your mower is supplied with cable fitted
with a non-re-wireable plug:
• The plug is fitted with a 13 amp fuse
which is the recommended fuse for
your mower.
• Only use replacement fuses which are
approved to BS1362.
• When changing the fuse in your plug,
always ensure the fuse cover is refitted.
If the fuse cover is missing or damaged
do not use the plug.

Note: Fuses do not give personal protection
against electric shock.
Plug replacement
• Disconnect the plug from the supply.
• Cut off the plug and dispose of

!
Note: Do not wire an extension cable directly
into your mower yourself. Instead, take your
mower to your nearest Black & Decker
service agent.
Increased safety can be obtained by having
a qualified electrician install a high sensitivity
(30mA) circuit breaker in the house wiring.
If you do not have such a circuit breaker
installed, or you do not wish to have one
installed, then we strongly recommend that
the electrical power to your mower be
supplied through a high sensitivity residual
current device (RCD). The RCD is designed
to provide a high degree of personal
protection against harmful electric current
should fault conditions occur.
Warning! The use of an RCD or other circuit
breaker unit does not release the operator of

familiarise yourself with the individual parts of
your mower.
The main parts of your mower are your
mower body (1) which comprises the cutter
cover (2), motor cover (3), air vent shroud (5),
pivot blocks (6) and pivot pins (8).
The handle (10) comprises the lower handle
(11), the upper handle (12), switch box (13)
with switch lever (14) and safety lock-off
switch (15), electrical supply cable (16), the
cable clips (17), and the handle clamp
assemblies (18) which each comprise a wing
nut, washer and bolt.
Note: The electrical supply cable should be
positioned on the right-hand side of your
mower when viewed from the operating
position. Ensure that this is not damaged
or twisted before you begin to assemble
your mower.
Assemble the lower handle to your mower
body, as follows:
• Place the lower handle (11) into the pivot
B
blocks (6) on the cutter cover (2).
Note: It will be necessary to tilt the lower
handle towards the rear of your mower to
allow pivot pins (8) to fit correctly.
• Fit the pivot pins (8) through the holes in
the pivot block flanges (6) and through
the holes in the lugs on the lower
handle (11).
• Using a mallet, or similar tool, tap the
pivot pin (8) through the inner part of the
pivot block (6). The hooks on the end of
the pivot pin will click into position behind
the inner wall, retaining it in position.
• Repeat the process on the other side.
With the lower handle in position, assemble
the upper handle, as follows:
• Place the upper handle (12) over the
C
lower handle (11). Ensure the upper bend
is as shown in Fig. A.
• Align the holes in both the upper and
lower handles and fit a bolt (20) through
each hole. Fit a washer (21) to each bolt
and fit the wing nuts (22) on to the bolts.
Tighten each one with hand pressure only.
Note: Do not use a spanner or other
implement to tighten the wing nuts.
With the upper and lower handles
assembled, fit the switch box to the upper
handle, as follows:
Note: The switch box must be positioned on
the right-hand side of your mower.
Ensure that the electrical supply cable is
not twisted before you begin to assemble
the handle.
• Locate the two pins on the switch box (13)
D
with the holes in the upper handle (12).
• Fit the retaining plate (23) over the stem
of the handle (12) ans secure in position
using the two screws (24) provided.
Note: Do not overtighten these screws - light
pressure will be sufficient to hold the switch
box in position.
• Finally, secure the electrical supply cable
to the lower handle using the cable clip
(17) supplied.
Handle operation (Fig. E)
The handle has three positions, two storage
E
(park) positions and one operating position.
Positions 1 and 3 in Fig. E are the storage
(park) positions and F is the operating range.
For storage purposes, the handle assembly
can be set to position 2 or 3, as follows:
• With the handle in its working range F,
pivot the handle downwards until it
contacts the stops on the end of the
handle tube. This is the park position
2 for the handle.
• The handle can be moved to a park
position 3. Push the handle upwards in
the working range F, to the top position
1. Pull the handle upwards. While still
pulling the handle upwards, pivot the
handle down towards the ground to
position 3.
Height of cut adjustment (Fig. F & G)
Your mower employs a manual method of
F
height of cut adjustment. The method
involves changing the arrangement of the
spacers fitted between the impeller and the
blade, and applies to mowers fitted with the
steel or plastic blade cutting systems which
can be purchased as an accessory.
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.
The procedure for adjusting the height of cut
is as follows:
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.
ENGLISH
• Ensure your mower is disconnected from
the mains supply.
• Place the handle assembly into position
3 (see “Handle operation”).
• Turn your mower over onto its side so
that the underside of the cutter cover
is exposed.
• Using a cloth placed over the blades or
heavy duty gloves to protect your hands,
grip the blade and, using the spanner
provided, loosen and remove the nut
(21) from the motor spindle. Turn the nut
in anti-clockwise direction to loosen it.
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).
• Remove the blade nut, white washer

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.

(26) (if supplied), spacers and blade
(21-24) and re-assemble to give the cut
height required, showing the 6 cut
heights available.
• Once the cut height is selected,
re-assemble the blade, ensuring the
cutter blade (23) is assembled with the
cutting tips downwards as shown in
Fig. F and ensure the white washer
(26) is fitted to the blade nut.
• Ensure the blade nut (21) is tight.
Note: Your mower is supplied with the blade
height in position E (Fig. G).
• Always re-fit 3 spacers and never fit more
or your mower will become unsafe.
Observe all the relevant warnings when
using your mower .
We recommend the dir ectional 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.
