Standard hexagonal die size: 10.16.25.35.50.70.95.120.150.185.240.300 mm2
If ask for special size or special shape, please contact the distributor or manufacturer,
they can make die according to detail requirements.
Please select the correct die according to the AL/CU terminal which to be
crimped, to choose the wrong die may cause loose crimping result or generate
a lot of burs.
MAINTENANCE AND SERVICING
The tool earns a high precise design, please use it properly and do not disassemble
it by unprofessional person, otherwise we will not responsible for the problems cause
by above misuse. Or we will carry out repair if the users are willing to pay for the
spare parts cost.
1. Keep tool dry. Any water may corrode the tool surface, metal or electrics parts. If
contact water, take out the battery and assembly it back when the tool is fully
dry.
2. Avoid great temperature fluctuating to the tool. Otherwise it will cause the plastic
housing to be deformed, shorten the life span of the electric parts and damage
the battery.
3. Please do not use any chemical agent to wash the tool.
4. In order to prolong the life span, please change the hydraulic oil per year.
5. If the tool not used for a long time, please make sure the position stay on its
starting position, clear up the tool and paint the rustproof oil both to the tool and
accessories. Take out battery and put them into box and store the tool in a dry
surrounding.
6. The sealing kit inside the tool will be abraded in some degree after using, when
the oil leaking a lot, please contact the distributor to replace the sealing kit in

timely.
.
1. Do not knock any parts of the tool, otherwise it will cause injury.
2. The design of the limit screw on the head is for preventing the head from
dropping or popping.
3. Make sure the head was locked firmly during operation.
4. The built-in safety valve goes through strict pressure test before marketing,
please do not adjust the pressure by unprofessional person. If the pressure
is not enough please return the tools back to the service center, The tool
only can be reused after checking and testing trained person.

The crimping process can be interrupted at any moment by releasing the trigger.
Do not put your fingers into the head of the tool during operating. Your fingers
could be pinched very severely.

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 you 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 our 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.
3. Function description
1. MCU - automatically detect the pressure during operation and
provide security protect, shut off the motor and reset automatically after
operation.
2. Auto reset - release the pressure automatically, retract the piston to
the starting position when reached the max output.
3. Manual reset - can retract the position to the starting positioning
in case of an incorrect crimp
4. The unit is equipped with a double piston pump which is
characterized by a rapid approach of the dies forwards the connector and a
slow crimping motion.
5. The crimping head can be smoothly turned by 360° around the
longitudinal axis in order to gain better access to tight corners and other
difficult working areas.
6. One significant sound will be heard and a red display
flashes if any error occurs.
A white LED illuminates the working space after activating the trigger. It
automatically switches off 10 sec. after releasing the trigger.
7. The whole tool is controlled by one trigger. This results in any easy
handing and a better grip compared to a two button operation.
8. Li-ion batteries do neither have a memory effect nor self discharge.
Even after long periods of non operation, the tool is always ready to operate.

In addition we see a lower power weight ratio with 50% more capacity and
shorter charging cycles compare to Ni-MH batteries.
9. A Temperature sensor makes the tool stop working automatically
when the temperature over 60°C under long time working, the fault signal
sounds, it means the tool can't continue work until the temperature reduced
to the normal.
Serious
No.
