There is danger of injury when unintentionally actuating
the On/Off switch with the locking button.
Tool assembly (see figure C and E)
Fit the hedge trimmer head and the telescopic handle flush
together with each other and secure them by screwing the
connector(3) on. Ensure both parts are fitted properly
mounted and locked.
Attach the hooks of the shoulder strap (8) to the strap
loops (7)/(9) of the handles. Please notice that the shoulder
strap has two hooks that are different in size. Make sure that
the larger hook (16) is fitted to the rear handle strap
loop (9) and the smaller hook (15) to the front handle strap
loop (7).
Remove the blade guard.
Adjusting the telescopic height (see figure F)
Loosen the telescopic height adjustment (5) by rotating the
sleeve, extend the telescopic tube (4) to the required length
and tighten the sleeve of the telescopic height
adjustment (5) again.
The telescopic tube (4) can be extended from 2.1 m to
2.60 m depending on the application and the height of the
trimmed head.
Adjusting the pivoting head (see figure H)
Press two pivoting head adjustment buttons (2) simultan-
eously, adjust the pivoting head to the required position by
moving the hedge trimmer head upwards or downwards, re-
lease the pivoting head adjustment buttons (2) and make
sure that the hedge trimmer head is properly locked.

Operation
Switching on and off (see figure I)
To switch on the power tool, first press the lock-off
switch (10) and then press the On/Off switch (12). Keep the
On/Off switch pressed while operating the machine. You can
release the lock-off switch while the tool is switched on.
To switch off the power tool, release the On/Off switch

discharged, the power tool is switched off by means of a pro-
tective circuit: The application tool no longer rotates.
Working instructions (see figure J)
Anti Blocking
This tool has the anti-blocking system installed for your be-
nefit.
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 3 s.
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).
Corrective Measure
Apply lubricant spray (1 609 200 399)
Clean blade
