Before use

Assembly of the protection shield 

(Fig. 2)

Slide the included protection shield (3) over the blade rail 

and fix it from both sides at the housing using 2 screws 

on each side as shown in Fig. 2.

Power connection

The machine can only be connected to a single-phase 

a.c. current connection. The machine is protectively in-

sulated in accordance with classification II of VDE 0740. 

Before using the machine ensure that the mains current 

agrees with the operating voltage data on the machine’s 

identification plate.

Power Circuit Breaker:

Machines which will be used in different outside loca

-

tions must be connected to a Power Circuit Breaker.
Securing the power supply cable

 (Fig. 3)

Only  use  cables  (extension  flex)  that  are  approved  for 

outdoor use. The cable diameter must be equal to or bigger 

than 1.5mm² for cable lengths up to 75m.

Put  the  coupling  of  the  extension  flex  onto  the  shears‘ 

plug. For strain relief, stick a loop of the extension flex 

through the opening in the handle and put it onto the 

strain relief hook. 

Extension flexes with a length of more than 30m reduce 

the machine’s output.

Instructions for use of the equipment  

Do not use the trimmer in rain or for cutting wet 

hedges!

Check the hedge trimmer flex and its connections be

-

fore each and every use for visible signs of damage 

(disconnect the power plug)!  Do not use a faulty flex.

Gloves:

Protective gloves must be worn when using the 

hedge trimmer.

Switching the hedge shears on/off

(Fig. 4)

When switching the hedge shears on take a safe stand. 

These hedge shears have a two-hand safety switch. To 

switch the hedge shears on the bar switch in the handle 

(A) and the grip switch of the bow-type handle (B) must 

be pushed down.

To switch the device off let go of both 

switches. The motor already stops if one of the two 

switches is released.
The breaking mechanism causes the blade to stop within 

0.5 sec. The sparks (flashes) developing from this in the 

area of the upper ventilation slots are normal and harm-

less for the device.   

Adjusting the turning handle 

(Fig. 5)

To facilitate your work the hedgetrimmer are equipped 

with a turning rear handle that can be set in 5 different 

positions [ right (45°/90°), left (45°/90°) and normal ]. The 

purpose of this mechanism is that especially for cutting 

in vertical direction the hedge shears can be held in their 

ergonomically most favourable position whereby an early 

fatigue of the user is avoided.
Please proceed as follows to change the position of the 

handle:

Release switch (A). Press the locking pin (C). The handle 

is now unlocked and can be turned to the desired posi-

tion. In the desired end position, the pin locks back into 

place and securing the handle and avoiding an accidental 

change of the position.

Please bear in mind that the locking pin (C) can only be 

pulled  back  when  the  switch  (A)  is  not  activated  (held 

down).  Make  sure  that  the  locking  pin  locks  into  place 

again after repositioning the turning handle. Only then the 

switch can be activated anew.

Maintenance

Always disconnect the plug from the power socket 

before commencing any work on the machine.

Important: Always clean and oil the blades after pro-

longed use of the hedge trimmer. This will greatly affect 

the life of the equipment. Damaged cutting units must be 

properly repaired immediately. Clean the shearing blades 

with a dry cloth or – in case of heavier dirt – with a brush. 

Attention: Danger of injury!

Oiling of the blades should 

ideally be carried out using an environmentally friendly 

lubricant (Fig. 9).

Sharpening of the blades

The blades generally do not need servicing and do not 

require resharpening if used correctly. 

Changing the blades

Only correct installation of the blades will guarantee 

problem-free operation and function of the above men-

tioned safety feature of the blades. Changing of the 

blades should therefore only be carried out at a specialist 

workshop. 

Holding the hedge trimmer when in use 

(Fig. 6+7)

This equipment will enable you to cut or trim bushes and 

hedges easily and comfortably.

Trimming of hedges

-  Young shoots are best cut in a scythe movement.

-  Older and stronger hedges are best cut in a sawing 

movement.

-   Branches, which are too thick for the hedge trimmer, 

should be cut with a saw.

-  Sides of hedges should be cut upwards in a taper.

In order to achieve an even height

-   Fix a guide line at the required height.
