_____________________________________________________________________________
With those dies mentioned in Table 3a only Klauke cable lugs and connectors „Standard
type“ are supposed to be crimped. Crimping of commercial cable lugs and connectors of other
suppliers will not result in a perfect crimp.
The same is applicable for conducting material table 3j. No guarantee can be given for
crimping C-clamps of other suppliers.
Despite the same code numbers the compression width for copper and aluminium cable lugs
and connectors is different. Besides the marking of the dies the plating is different too.
Attention
Even if the code number is identical only those dies should be used which are
suitable for the material.
5.4. Service and maintenance instruction
The electro-hydraulic unit must be cleaned and dried after each use. The pump is basically
maintenance free, only the oil level must be checked regularly and the pump has to be
inspected for possible damages and wear.
The HK12/2EL220 is equipped with an oil level
control glass which enables the operator the check the
oil without opening the pump.
The oil level should be 10 mm below the top of the
control glass. If the oil level is too low please fill up
the oil accordingly.
To check the oil level of the HK12/2EL/380 use the
control pin of the oil filler (Pos.-No. 4). If the oil level
proves to be unsatisfactory (below the min. mark)
additional oil has to be added. To do that open the oil
filler plug (Pos.-No. 4) and fill in the oil. After
servicing the oil filler plug must be screwed on again.
The hydraulic hose (Pos.-No. 9) and the armature
must be checked for damage and leakage.
5.5. Oil changing cycles
It is advisable to have the unit serviced by a specialist in regular intervals to safeguard a
technically proper state before use.
