be heard (see figure B), simultaneously press the front
switch (4) and the switch at the rear handle (2)
(see figure D).
In order to switch the device off, either release the switch at
the rear handle (2) or the front switch (4) or both at the
same time (see figure E).
Sawing Function
Although the tooth opening allows wood to be cut up to
Ø 20 mm can be cut with the 55 cm cutting blade, the tip of
the blade is designed to cut wood up to Ø 25 mm.

Working with the Hedge trimmer (see figure F)
Move the hedge trimmer evenly forward along the cutting
line. The double edge cutting blade enables cutting in either
direction, 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 15 rounds when the switch is actuated.
During repeated heavy cutting scenarios, the anti blocking
function could disable for 15 seconds to allow it to reset.
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).
