To cut the sides straightly, we recommend cut-
ting from bottom to top in the direction of
growth. Younger stems tend to move outwards
when cutting them from top to bottom, resulting
in shallow patches or holes in the hedge.
To reach a level finish, fasten a piece of string
along the length of the hedge at the required
height and use as an alignment guide. Cut the
hedge just above the string.
Always take care to avoid cutting into objects
such as wire, which could cause damage to the
cutting blades and the drive. Anti Blocking
The garden product has a patented feature
which works as follows:
If the blade stalls on a tough material, the load
of the motor increases. The intelligent micro-
electronics senses this overload condition and
repeatedly reverses the motor, in order to pre-
vent stalling and to cut the material through.
This audible reversing cut action continues for
up to 3 s.
After cutting through, the garden product con-
tinues in its normal mode, or in case the over-
load condition continues the blades automati-
cally stop in the open position (e. g. in case a
piece of metal fence accidentally blocks the gar-
den product).
