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.
