are not compliant with the specifications.
Cause:
It is likely that the leads being cut are different from those
normally used due to production changeover, or that cutting is
being performed on leads that are not compliant with
specifications.
Solution: Check if the lead is compliant with the specifications of HAKKO
153/154 and if the bending wheel and bending wheel guide are not
deformed.
When the lead is not compliant with the specifications but no part deformations are found
Refer to the table below and change the lead to that which is compliant with the specifications.
If the unit is continuously cutting leads that are
not compliant with the specifications, the
bending wheel teeth become crooked. This can
cause a wheel-off or deformation of the blade
spring.
