Condition
Lay boundary wire around objects which the
lawnmower might run on top of (e.g. rocks, tree
roots, etc.); these objects must be removed
from the work area.
The boundary wire entry and exit points for a
round area should be separated by less than
5 mm. (However, the boundary wire should not
cross itself.)
There must be 30 cm to 50 cm of space
between the boundary wire and large objects.
(This space can be reduced to as low as 30 cm
if you set [Wire Overlap] to a low value. For
details, consult your dealer.)
Lay fence around areas which the lawnmower
might fall into, such as uneven ground, ponds,
pools, driveways, or other areas with differences
in height.
The work area must conform to the following
conditions if it includes sloping areas.
Laying the boundary wire where the slope is too
steep has a bad effect on the lawnmower. This
is because the lawnmower follows along where
the boundary wire has been laid.
• The lawnmower can operate on slopes of 24°
(45%). Do not include slopes in the work area
that are more than 24° (45%).
• Lay the boundary wire in locations that have a
slope of less than 10° (17%).
• If the location in which you are laying the
boundary wire has a slope that is steeper than
10° (17%), do the following.
- Do not lay the boundary wire laterally across a
slope that is steeper than 10° (17%).
- Lay the boundary wire laterally across a
relatively flat space, with a slope of less than
10° (17%), that comes after the location where
the slope is more than 10° (17%). (Refer to the
left diagram.)
