There
may
be
parts
of
your
garden
which
will
be
challenging
or
even
impossible
for
your
Robot
Mower.
Your
Robot
Mower
will
not
stray
beyond
the
boundary
wire
you
must
lay
around
your
garden.
It
will
change
direction
on
making
contact
with
things
like:
posts
and
poles
(e.g.
washing
lines),
fences
and
walls
around
trees
But
it
will
need
to
be
kept
away
from:
dug
borders,
trees
with
exposed
roots,
flower
beds,
ponds
and
water
features,
excessively
uneven
terrain.
The
wire
must
be
kept
taut
and
never
be
allowed
to
loop
or
cross
over
itself.
Ideally
if
ground
is
particularly
uneven
the
wire
can
be
buried
up
to
40
mm
deep
and
pegged
down
to
secure.
This
can
be
achieved
easily
with
a
manual
edging
tool.
If
this
is
not
desired
or
possible
then
the
wire
should
be
firmly
pegged
around
the
garden
with
pegs
at
a
minimum
of
1
m
intervals,
keeping
the
cable
taut
to
avoid
it
being
cut
by
the
mower,
more
so
at
corners
and
over
uneven
terrain.
The
cable
should
be
positioned
a
minimum
of
30
cm
from
the
edge
of
the
garden,
as
the
mower
will
overlap
the
wire,
although
it
will
not
stray
past
it.
On
corners
the
wire
should
not
be
laid
at
a
sharp
angle
or
right
angle,
but
curved
or
a
series
of
obtuse
angles.
The
mower
can
detect
a
signal
from
the
wire
from
as
much
as
18
m
away.
It
should
be
noted
that
due
to
this
set
up
some
areas
of
the
lawn
will
not
get
mowed
such
as
outside
the
perimeter
edges.
These
can
be
maintained
using
a
suitable
grass
trimmer.
If
the
ground
where
the
wires
are
to
be
laid
is
particularly
dry
and
the
soil
hard
from
lack
of
rain,
it
will
help
to
thoroughly
water
the
garden
before
attempting
to
lay
your
perimeter
wire.
