2. Description of components:

Parts No.




Die holder For fixing die


Die For crimping, interchangeable die


Latch For locking/unlocking the crimping head


Limited screw For prevent head from dropping or popping


LED indicator For indicating the operating condition and battery discharging situation


Retaining clips For locking/unlocking die


A white Led light To illuminate the working area


Trigger For starting operation


Retract button For manual retracting the piston in case of an incorrect operation


Battery lock For locking/unlocking the battery


Battery For supplying power, rechargeable Li-ion(18V)



The battery can be used for hundreds of times, when the life span reduced obviously, change to a new battery please.

Please charging the battery in time to avoid it to be used up absolutely; otherwise it will become useless forever, if the battery not be used for a long time, it will discharge automatically. Make sure to charge it one time per/each quarter.

3. Usage of the tool:

1) First people have to check the LED indicator is light or not. If the indicator is light on for more than 5 seconds, it means no power of the battery and should change the full powered battery to settle on the tool

2) Select the right dies for the Intended application.

 Don’t operate the tool with dies.The crimping head has to be opened by pushing the latch, place two dies up and down after activating the retaining clips. Then the connecting material shall be positioned in the crimping head correctly in order to start the crimping procedure.3) A crimping process is initiated by switching the trigger. It is defined by the closing motion of the dies. The connection material is positioned in the stationary half of the crimping dies and the moving part is approaching the compression point.4) A crimping cycle is terminated when the dies contracted each other and when the maximum crimping force is reached. After the crimping cycles is completed the piston retracts automatically. Afterwards a new crimping cycle can be initiated or the crimping process can be terminated by opening the latch and remove the connecting material out of the head.
