3.2 Brief description of the important
features of the unit
The hydraulic unit incorporates an automatic retrac-
tion which returns the piston into its starting position
when the maximum operating pressure is reached.
A manual retraction allows the user to return the pis-
ton 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 closing 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
blades towards the conductor/cable and a slow cut-
ting motion.
The cutting head can be smoothly turned by 330°
around the longitudinal axis in order to gain better
access to tight corners and other dif cult working
areas.
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 III)
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.
Li-Ion batteries do neither have a memory effect 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
3.3 Description of the tool indication
This tool is equipped with a special circuit board incorpo-
rating several important features to inform the user about
the current status of the unit. Please see Table 1 for more
details.
Prior to operating the unit the charging level of the battery
(pic. 1, 2) should have been tested. A low charging level
can be detected by the ashing of the LED (pic. 1, 1) for
20 s at the end of a cutting cycle.

4. Remarks in respect of the
determined use
Before starting any work on electrical appliances it must
be safeguarded that there are no live parts in the immedi-
ate assembly area of the user. Is this not possible special
precaution measures (see EN 50110-1) for working near
live parts must be provided.
Do not use this tool when you are tired, on drugs, had
alcohol or if you are medicated.
4.1 Operation of the unit
The cutting procedure is initiated by actuating the trigger
(Picture 1, 3). The cutting process is de ned by the clo-
sing motion of the blades (Picture 1,7).
Attention
The cutting process can be interrupted at any
moment by releasing the trigger.
The cutting process is terminated when the cutting blades
completely overlap. After having completed the cut the
blades return into the starting position by brie y actuating
the retract button (Picture 1.4) once. After a few seconds
a second cutting cycle can be initiated.
4.2 Explanation of the application range
Our electric-hydraulic cutting tool can cut light armoured
copper and aluminium conductors or cables up to a maxi-
mum diameter of 50 mm.
Attention
Do only cut light armoured copper and Alumini-
um conductors and cables.
Attention
Do not cut Steel armed cables and conductors
or cables with a steel core.
If different conducting materials have to be cut, please
contact the manufacturer.
Attention
Do not cut live cables or conductors.
This is not an insulated tool.
The hand held tool is not supposed to be restrained in a
vise. It is not allowed to use the tool in a stationary appli-
cation. Complying certain conditions the unit can be ope-
rated stationary with our presentation support EKST-L.
The conditions can be taken from the instruction manual
of the EKST-L.
The tool is not designed for continued cutting operations.
After a sequence of approximately 30-40 completed cuts
you have to make a break of 15 min. to give the tool time
to cool down.
Attention
Too intensive use can cause heat damages for
the tool
Attention
During the operation of electric engines sparks
can occur which might ignite highly infl ammab-
le or explosive liquids and materials
Attention
Electric-hydraulic cutting tools should not be
operated in pouring rain or under water.
