We recommend to replace the P side and H side at the same time when
you need to change wheel guide or wheel.
If the parts cannot be removed from the shaft, a burr may have been
formed on the shaft due to overtightening the screws. In this kind of
situation, please send for repairs.
Troubleshooting HAKKO 153/154
Case 1: Lead bending becomes inadequate.
Cause: Blade spring in the bending wheel guide is worn out from age or

is deformed due to use of leads thicker than those determined by
the specifications.
For the maximum applicable lead diameters, see the table below.

Solution: Replace the bending wheel guide with a new one.
Replacement parts list for HAKKO 153/154
It is advisable to replace both H-side and P-side
bending wheels at the same time even when
only either one of them requires replacement.
Case 2: Leads get twisted. Why?
The probable cause is the deterioration of the bending wheel and bending wheel guide.
Replace them with new ones.

Case 3: Burrs are left at cut end faces. Why?
The probable cause is a chipped cutting blade or the deterioration of the bending wheel and
bending wheel guide (See the photo below).
Replace them with new ones.

If the backlash is too large when the cutting wheel guide is
attached to the cutting wheel, they are worn out. Wear causes gaps and
excessive backlash.
Case 4: Bending wheel guide comes off.

There are two major suspected causes.
Cause 1: The handle was turned in a reverse direction during the work.
Cause 2: The unit is being used for the cutting of leads that are not compliant
with the specifications.
Cause 1: The handle was turned in a reverse direction during
the work.
Cause: It is suspected that the handle was turned in the reverse direction
to release a lead caught in the unit during the work.
Solution: Check if the bending wheel and bending wheel guide are not
deformed as shown in the photo below.
When deformed
Replace them with new ones.
When not deformed
Dismount the bending wheel guide from the bending wheel and then put them together again. If the wheel
guide still continues to come off, replace the bending wheel and bending wheel guide.
When you want to stop the work, cut the tape
where appropriate, and finish the cutting and
forming of all leads remaining in the lead
former.
When the parts cannot be removed from the
shaft, burrs are thought to have been formed on
the shaft due to excessive tightening of screws.
In this case, send the unit for repair.
Cause 2: The unit is being used for the cutting of leads that

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 bendin
g 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.

simultaneously.

Case 5: Adjustment of parts such as bending wheels and cutting
wheels is becoming increasingly more difficult. Why?
The probable cause is the deterioration of shaft and bending wheel.
If the unit must be adjusted often due to the frequent changes of pitches to form (e.g. after
each set of work), the grooves on the main shaft and bending wheel (where the screws touch)
are scratched, and the unit will not operate smoothly.
1. When the cutting wheel does not operate smoothly
Burrs are formed on the part of the bending wheel where the cutting wheels
can traverse (A).
Polish the part around the groove on the bending wheel with a file.
*To file the groove on the bending wheel, first remove it from the main shaft.
2. When the bending wheel does not move smoothly
Burrs are formed on the part of main shaft where the bending wheels can
traverse (B). Polish the part around the groove on the main shaft with a file. If
the movement does not improve, the shaft may be bent.
Replace it with a new one.
* To file the main shaft, first remove it from the Lead Former.
