2.1) Operator information:

- The instructions within this operation and maintenance manual should always be followed.

- The tool should only be used by competent personnel who are familiar with the instructions

contained within this manual.

2.2) Application:

Not to be used for any other purpose than for which the tools were designed

Do not use these crimping tools to crimp other type of lugs or connectors.

2. INSTRUCTIONS FOR USE

2.3) Die proﬁle selection:

- Fully open the tool handles

- Press down the locking-pin of the indexable die plates.

- TNH6-70: Rotate the die proﬁles until the stamped cross section matches the cross section on

the cable lug/connector.

- TND6-70: Rotate the die proﬁles until the 'K' number matches the equivalent No. marked on

the palm of the terminal lug or the wall of the splice.

- Release the locking-pin until the die proﬁle is ﬁxed.

- Adjust the second die proﬁle in the same manner as the ﬁrst by following the above instruc-

tions. Both proﬁle dies must have the same 'K' number.

Incorrect choice of die proﬁle will result in tool damage and/or aﬀect the quality of the

crimped joint, leading to potential failure

2.4) Cable preparation:

- Cut the cable perpendicular to the central axis.

- Neatly strip the insulation over a distance equal to the barrel length allowing an additional

10%. Ensure all traces of the insulation are removed. Avoid damage to the outer layer of con

ductor strands.

- Clean the conductor carefully.

- Sector-shaped conductors must be pre-rounded

before crimping.

2.5) Crimping procedure:

Open the crimping tool handles and position the

connector at the lower part of the die proﬁle (see

image). The terminal lug/splice axis should be per-

pendicular to the plane of the die proﬁle

- Apply a small pressure to the handles to close the dies suﬃcient to trap the connector

- Fully insert the conductor into the connector barrel.

- Apply suﬃcient force to close the handles and cause the dies to compress the connector and

conductor until the die proﬁles become in contact.

- Apply the correct number of compressions as deﬁned on page 4, in the direction deﬁned in

the ﬁgure below.

- The crimping bite width is 5mm for these tools.

2.6) Number of compressions required:

- The table below shows the number of compressions required per conductor size.

- If only one compression is required, please position the crimp at the midpoint of the connec-

tor barrel. If several compressions are required these should be spaced evenly.

- Remove dust, humidity and other impurities with a clean brush or a soft cotton-free cloth.

Never use any items which may damage the tool.

- Take care that the bolts, any moveable parts and the tool surface are coated with a thin ﬁlm of

high quality oil.

- Ensure die proﬁles can be rotated freely prior to use

- Store the tool in a dry and clean area.

3.1) Safety advice:

- Ensure hands are free of the crimping area at all times

- Ensure that the dies are completely closed to obtain a full compression

Never work with energised conductors. Ensure that voltage has been switched oﬀ before

starting work and check this with adequate instruments.

- Alteration of the tool is prohibited.

- Before operating the tool, check for any damage, the tool should not be used if damage is

visible

- The tool should be returned to the nearest Cembre service centre for any repairs required.

PROBLEM: CAUSE: SOLUTION:

Excess ﬂash (wings) on

the crimped joint

- A smaller die proﬁle than required has

been selected.

- Incorrect connectors have been used

- Other causes

- Adjust die proﬁles to match the

connector requirement

- Verify the connector type and size

is correct

- Return tool to Cembre for inspec-

tion and repair

The compression is of

insuﬃcient depth and

the conductor can be

pulled from the joint

- The die proﬁle is larger than required

- Incorrect connectors type have been

used

- Other causes

Die proﬁle cannot be

changed - Locking bolt has snapped in - Press down locking bolt

Proﬁle dies are diﬃcult

to rotate

- Tool is soiled

- Tool is insuﬃcient oiled

- Clean the tool

- Oil the bolts and screws

- Return tool to Cembre for inspec

tion and repair

Tool has no tension

when handles are fully

closed

- Tool is worn - Return the tool to Cembre for

inspection and repair
