Working with the Hedgecutter (see figure E)
Move the hedgecutter evenly forward along the cutting line.
The double edge cutting blade enables cutting in either dir-
ection, or with a side to side motion.
Cut the sides of the hedge first, then the top.
To cut the sides straightly, we recommend cutting from bot-
tom to top in the direction of growth. Younger stems tend to
move outwards when cutting them from top to bottom, res-
ulting 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.
Pay attention that no objects such as wires are cut. The
blade or drive can be damaged.
Anti Blocking
If the blade stalls on a tough material, the load of the motor
increases. The intelligent micro-electronics senses this over-
load condition and repeatedly reverses the motor, in order
to prevent stalling and to cut the branch through.
This audible reversing cut action continues for up to 3 s.
After cutting through, the garden product continues in its
normal mode, or in case the overload condition continues
the blades automatically stop in the open position (e.g. in
case a piece of metal fence accidentally blocks the garden
product).
Corrective Action
