4.2. Brief description of the important features of the unit
- The hydraulic unit incorporates an automatic retraction which
returns the piston into its starting position when the maximum
operating pressure is reached.
- The unit is equipped with a special brake which stops the forward
motion of the piston/dies when the trigger (Pos.-No. 1) is
released.
- The unit is equipped with a double piston assembly which is
characterized by a rapid approach of the dies (Pos.-No. 10)
towards the connector and a slow crimping motion.
- The crimping head can be turned 360° stepless around the
longitudinal axis in order to gain better access to tight corners and
other difficult working areas.
- The EPG Plus is equipped with a microprocessor which indicated
service intevals, internal checks and low battery charges. It also
shuts off the motor automatically after the crimp is completed.
4.3. Description of the light diode display
This tool is equipped with a special circuit board incorporating
several important features to inform the user about the current
status of the unit. The diode (Pos.-No. 6) signals in the following
cases:
- The diode will signal periodically a few times while the battery
(Pos.-No. 7) is being inserted into the tool. This indicates that the
electronic circuit board performed its self-test successfully.
- If the diode signals continuously after a crimping cycle for
approx. 20 sec. the battery is discharged and must be recharged
again.
- Does the diode signal periodically at the end of a crimping cycle
for approx. 20 sec the unit must be returned to an authorised
Service Center for Service as soon as possible.
- In case of an error the light diode display also signals periodically
at the end of an crimping cycle. The signal indicates in this case
the circuit opening by the electronic fuse. A possible reason for
that is that a pressing cycle was performed with an incorrectly
low battery. If the signal occurs even after changing the battery
there must be a different error or a service is due. In these cases
the tool must be returned to the manufacturer or an authorised
service center.
- Signal the LED (Pos.-No. 6) for 20 s continuously and then
periodically a service is due and simultaneously the battery is
discharged.
5. Remarks in respect of the determined use

5.1. Operation of the unit

see
Before starting any work on electrical appliances it must be
page
safeguarded that there are no live parts in the immediate assembly
12, 13,
area of the user. Is this not possible special precaution measures
14
working near live parts must be provided.
14, 17
Now you have to select the right dies (Pos.-No. 10) for the intended
13, 14
application.
13
Attention
Don't operate the tool without dies.
2
The crimping head has to be opened by unhooking the latch (Pos.-
No. 3 & Picture 2 Pos A). Afterwards the retaining clips (Pos.-No.
13
4) have to be actuated (Picture 2 Pos. E) while the dies will be
inserted sideways into the open crimping head. After having
13, 16,
completely closed the crimping head the trigger lock (Pos.-No. 8)
17
for the trigger (Pos.-No. 1) must be released, which means that it is
13, 14
pushed down (Picture 2 Pos. D).
Prior to operating the unit the charging level of the battery (Pos.-No.
2 7) should have been tested
by the flashing of the LED (Pos.-No. 6) for 20 s at the end of a
12, 13, crimping cycle.
14, 16
The crimping procedure is initiated by actuating the trigger (Pos.-
No. 1 & Picture 2 Pos C). The crimping process is defined by the
closing motion of the dies. During that process the connecting
material is positioned in the stationary half of the die whereas the
moving part of the die is approaching the compression point
The crimping process is terminated when the crimping force is
reached. After having completed the crimp the dies return into the
starting position automatically. Afterwards a second crimping cycle
can be initiated or the it can be finished by opening the latch (Pos.-
No. 3 & Picture 2 Pos A).
Attention
After having terminated the crimping process
and prior to changing the dies the trigger (Pos.-
No. 1) has to be locked with the trigger lock
(Pos.-No. 8) to avoid unintended use.
In case of error or emergency the dies can be returned into the
starting position by actuating the retract button (Pos.-No. 2 &
Picture 2 Pos. B).
Attention
The crimping process can be interrupted at any
moment by releasing the trigger.
