on jobs that were easily done before.
When charging the battery for the first time, or
after prolonged storage, it will only accept an
80% charge.
After several charge and discharge cycles, the
battery will attain full capacity. The battery may
become warm while charging; this is normal and

hours. It can be removed at any time or left in
the connected charger indefinitely.

Hints for optimum use
Slightly tilt the tool (up to 15° relative to the
line of cut) so that the blade tips point slightly
towards the hedge (fig. D1). This will cause the
blades to cut more effectively.
Start by trimming the top of the hedge. Hold the
tool at the desired angle and move it steadily
along the line of cut (fig. D2). The double-sided
blade allows you to cut in either direction.
In order to obtain a very straight cut, stretch a
piece of string along the length of the hedge
at the desired height. Use the string (12) as a
guideline, cutting just above it (fig. D2).
In order to obtain flat sides, cut upwards with
the growth (fig. D3). Younger stems move
outwards when the blade cuts downwards,
causing shallow patches in the hedge.
Take care to avoid any foreign objects.
Especially avoid hard objects such as metal
wire and railings, as these could damage the
blades (fig. D4).
Regularly oil the blades.
Consider purchasing a spare battery to extend
the running time of this tool. The catalogue
number of the battery is found in the technical
data chart below.
