ENGLISH

For your safety, this tool is equipped with a double
switching system. This system prevents starting the tool
inadvertently and will only allow operation while holding
the tool with both hands.

Switching on and off

Switching on

Take hold of the front handle (3) with one hand so that the
front handle switch (2) is pushed into the body of the tool.
With the other hand, squeeze the trigger switch (1) to
start the tool.

Switching off

Release the handle switch (2) or the trigger switch (1).

Warning! Never attempt to lock a switch in the on position.

Hints for optimum use

Start by trimming the top of the hedge. Slightly tilt the
tool (up to 15° relative to the line of cut) so that the blade
tips point slightly towards the hedge (fig. C1). This will
cause the blades to cut more effectively. Hold the tool at
the desired angle and move it steadily along the line of cut.
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 as a guideline, cutting just above it.
In order to obtain flat sides, cut upwards with the growth.
Younger stems move outwards when the blade cuts
downwards, causing shallow patches in the hedge (fig. C2).
Take care to avoid any foreign objects. Especially avoid
hard objects such as metal wire and railings, as these
could damage the blades.
Regularly oil the blades.

Maintenance

Your tool has been designed to operate over a long period of
time with a minimum of maintenance. Continuous satisfactory
operation depends upon proper tool care and regular cleaning.

Warning! Before performing any maintenance, switch off and
unplug the tool.

After use, carefully clean the blades. After cleaning, apply
a film of light machine oil to prevent the blades from rusting.
Regularly clean the ventilation slots in your tool using
a soft brush or dry cloth.
Regularly clean the motor housing using a damp cloth.
Do not use any abrasive or solvent-based cleaner.
Make sure all switches are free of debris before and after
use.

Removing the guard (fig. A)
Warning!
Remove the guard for servicing purposes only.
Always re-fit the guard after finishing servicing.

Insert small pins into the holes (9) at either side of the
bracket (8) and pull the guard (4) forward.
Remove the pins and take the guard off the tool.
