Problem identification
Unexpected start-up in case of problem resolution, possible injuries.
Before any work on the tool, remove the rechargeable battery.
3.1 Diagnosis of mechanical or electro-mechanical faults
3.1.1 Tensioning process
Symptom Possible cause Rectification
The strap is not
tensioned or is only
tensioned with low
force although the
feed wheel is rotating.
This is creating strap
particles and dust.
1. The tensioning wheel is contaminated or worn.
2. The tensioning wheel has been installed in the oppo-
site direction of the arrow.
3. The tool is held too close to the front edge of the
package or the package item has a round cross-secti-
on.
4. The strap used is less than the specified minimum
strap thickness.
5. The rocker has hairline cracks.
– Clean or replace the tensioning wheel
(chapter 4.1.1)
– Turn the tensioning wheel according to
the printed arrow (chapter 4.1.1)
– Move the device back from the edge of
the packed product. Check suitability of
package shape and size.
– Select a strap thickness according
to the specifications in the operating
instructions. See operating instructions
(chap. 7).
– Replace the rocker # 50 (chapter 5.8).
The strap is not tensi-
oned. The feed wheel
does not turn although
the motor is running.
1. The spring clutch does not engage.
2. The freewheel pressed into the bevel gear # 132 has
a malfunction.
– Check the sleeve # 77 for smooth run-
ning. (See also chapter 5.7.1)
– Check the bearing pins # 61 for tight fit.
(See also chapter 5.7.1)
– Replace the bevel wheel with pinion
# 12 (chapter 5.9.1).
The strap tension
releases again after
tensioning. The feed
wheel rotates back-
wards.
1. The freewheel # 13 pressed into the base plate has
a malfunction.
– Replace the freewheel.
– Replace the bevel wheel with pinion
# 12 (chapter 5.9.1).
Instead of starting the
tensioning process,
only a beeping tone
sounds.
1. The battery was inserted after inserting the strap.
2. The signal “Rocker lever closed” is missing.
– Actuate the rocker lever
– The micro switch # 103 is defective or
is not inserted.
– The micro switch # 103 is not actuated
for mechanical reasons, e.g. the rocker
lever jams.
The tool ends the
tensioning process
although the strap has
not been completely
tensioned. In SEMI
or AUTO mode, the
tool also completes a
welding cycle.
1. The strap used is unsuitable for hand-held devices.
It causes too high friction when placed on top of ano-
ther.
2. There is a problem in the drive train.
3. The current measurement on the PCB supplies
incorrect values.
4. The motor is defective.
– Change to strap types suitable for
hand strapping.
– Check the tensioning drive
– (chapter 5.9.2).
–
– Replace the PCB.
– Replace motor.
