13 Service
Servicing and repair work must only be carried out by authorized service centres.
If the tool breaks down or does no longer operate do not disassemble it. Send it fully assembled to the local
service centre (see name and address on the rear page of this manual). Use original packing.
In order to prevent damages to the motor shaft the two needle free wheeling N3.4509/N3.4520 have to
be replaced after maximum 80 000 strapping cycles.  See 7.7 Request Maintenance
The battery powered plastic strapping tool P328S is a high performance tool. We strongly recommend you to
have it serviced by an authorized service shop after 12 months at the latest if used one shift per day. If used
two or more shifts per day the tool has to be serviced after a shorter period of time.
