5. WORKING WITH DIE SET
MultiBEX mx4 crimp tool consist of two rotational inserts. Inserts should be adjusted by pressing the release pin as shown in Fig. 3 and
rotating until reaching the right value. Rotation is possible in both ways. Handle should be open before die set rotating. Upper and lower
part of die set should be set to the same value to achieve the proper crimping. If upper and lower part of the die are not set to the same
value, the tool will block and crimping will be dimmed. Openings are marked with text and color code.

6. CRIMPING PROCEDURE
Prepare plug and cable according to the instructions packaged with the plug.
Ensure that appropriate contact is inserted into right crimping section. Follow instructions shown in Fig. 6 –Fig. 8
In case the tool becomes block for any reason, please follow unblocking procedure described in section 7.
After the full crimping cycle is done, let the tool open fully by itself in order to remove crimped plug.
Pull out the plug assembly. The tool is ready for next crimping cycle.
Fig.6 Fig.7 Fig.8
7. UNBLOCKING THE TOOL
❑IMPORTANT: Apply working force on the tool handles while unblocking. It will prevent hurting yourself and possible
damages on the tool.
❑In case of improper crimp, push the ratchet relief (Fig.9) in direction shown to unblock the tool and remove obstruction before
continuing with the work.
8. TOOL REGULATION PROCEDURE
❑After prolonged work period, tool crimping performance can change slightly due to final self-adjustment of the tools’ components.
This handtool is equipped with eccentric axle which allows periodical adjustment of crimping force and tool recalibration to
maintain correct crimp performance.
1. Loosen knurled nut (C) by turning it counter clockwise (Fig.10)
2. Press the nut until toothed adjustment wheel (B) is lifted so it can be rotated freely (Fig.9)
3. Insert screwdriver into adjustment wheel groove and rotate it to achieve desired pretension.
4. Marking dot at “0“ sets lowest pretension, while dot at “10“ sets highest pretension
5. Once pretension is set push adjustment wheel back into its position and tighten knurled nut
1. PRESS THE HANDLE UNTIL
TERMINAL IS HELD BY INSERTS
2. INSERT CABLE
3. PRESS THE HANDLE

9. MAINTENANCE AND INSPECTION
❑Crimping handtool MultiBEX mx4 is intended to be used for crimping coaxial plugs. Using this handtool for any other purpose, or for
crimping of any other objects, can result in damaging the tool and the objects being crimped and prevention of its normal further
functioning, for what manufacturer cannot be held responsible.
❑Handtool is equipped with full cycle ratchet mechanism which with optimized leverage system within the tools makes working with these
tools easy and simple. In case of improper crimp, ratchet release mechanism allows you to easily open the handtool and remove
obstruction before work is continued. Check unblocking procedure (section 9.).
❑Tool itself also incorporates possibility of periodical adjustment of the crimping force and tool recalibration via eccentric axle to maintain
correct crimp performance. Check regulation procedure (section 10.)
❑For removal of dust, moisture and other contaminants usage of clean brush or soft, lint-free cloth is recommended. Do not use
agressive agents (thinner, alcohol,...) or hard objects that could damage the tool.
❑Make sure that during the work bearing surfaces, shafts and pivot points are protected with thin coat of quality machine or motor oil. Do
not oil excessively.
❑When the tool is not in use, store it in a closed position –with handles closed. That will keep other objects from becoming stuck
between crimping dies and damaging them. Keep the tool in a dry and clean area.
❑Use only original spare parts.
