3.2 Brief description of the important fea-
tures of the unit
A manual retraction allows the user to return the pis-
ton/cutting blades into the starting position in case
of an incorrect crimp.
A manual retraction stop allows the user to stop the
retract at any position during the automatic retrac-
tion.
The unit is equipped with a special brake which
stops the forward motion of the blades when the
trigger is released.
The unit is equipped with a double piston pump
which is characterised by a rapid approach of the
dies towards the conductor/cable and a slower cut-
ting motion.
The pressure gauge can be smoothly turned by
360° around the longitudinal axis in order to gain a
better view on the pressure gauge.
The tool is equipped with a microprocessor which
shuts off the motor automatically after the cut is
completed, indicates service intervals and low bat-
tery charges and performs internal checks.
A white LED illuminates the working space after ac-
tivating the trigger. It automatically switches off 10
sec. after releasing the trigger. This feature can be
deactivated (see page V)
The compact ergonomically formed design consists
of 2 components. The grip area is rubber coated
and therefore slip resistent. The housing design is
optimized in respect of the center of gravity which
improves the handling and supports fatique-proof
working.
All tool functions can be controlled by
one
trigger.
This results in an easy handling and a better grip
compared to a two button operation.
Power saving function through motor switch-off .
Li-Ion batteries do neither have a memory eff ect nor
self discharge. Even after long periods of non ope-
ration the tool is always ready to operate. In addition
we see a lower power weight ratio with 50% more
capacity and shorter charging cycles compared to
NiMH batteries.
The oil used in our tool is particularly environmen-
tally friendly and and has been rewarded „
The Blue
Angel
“. The oil is also suitable for low temperatures
and has excellent lubrication characteristics

3.4 Description of the actuating and con-
trol functions
The battery capacity must be checked by briefl y actuating
the trigger. Does the LED fl ash as indicated above then
the battery must be recharged because the battery capa-
city might not be suffi cient to complete the cutting cycle
(worst case scenario assumed).
When actuating the trigger (Picture 1,6) hydraulic oil is
pumped from the oil reservoir into the cylinder of the cut-
ting head. From outside the system this procedure can be
monitored by the rise of the needle of the pressure gauge
(Picture 1, 8) respectively the closing motion of the bla-
des. As soon as the blades (Picture 1,10) touch the cable,
respectively the shift pressure is reached, the pump swit-
ches from the fast advance speed into the slow working
speed. After this change the blades start penetrating the
cable.
After the cable is cut the pressure indicated by the pressu-
re gauge drops signifi cantly. The trigger must be actuated
until the max. operating pressure is reached and the reli-
ef valve is activated. The max. operating pressure is the
highest pressure which can be reached in the system. An
increase of pressure is limited by the release valve. The
circuit board controls the cutting cycle on its own while the
trigger is actuated.
When reaching the max. operating pressure of 625 bars
the actual value of the operating pressure must be deter-
mined with the help of the pressure gauge and possibly
recorded. Afterwards the cutting cycle can be terminated
either by actuating the trigger again or by actuating the
release button (Picture 1,4) once.
The cutting cycle is terminated now and the cable is cut.
The blades (Picture 1,10) will be returned into their star-
ting position on its own.
3.5 Description of the connecting devices
The connecting devices (Picture 1,9) represents a de-
tachable connection between the drive unit and the insu-
lating hose. They consist of a female and a male coupling
which can be engaged or disengaged and present in the
engaged state a pressure prove, leakage free connec-
tion.
3.6 Description of the cutting procedure
With scissors style cable cutter heads the the two blades
(Picture 1,10) move towards each other on a circular path
towards the cable.
The cutting head (Picture 1,12) must be positioned in an
angle of 90° towards the cable in order to avoid undesired
shearing forces. The cable must be fed between the open
cutting blades.
In the slow working speed the blades penetrate the cable.
The pressure pick-up happens as described in the previ-
ous chapters.
