13 Adjustment
Please observe all notes from Chapter 1 Safety of the instruction manual! In
particular care must be taken to see that all protective devices are refitted
properly after adjustment, see Chapter 1.06 Danger warnings of the instruction
manual!
Unless stated otherwise, during all adjustment work the machine must be
disconnected from the electric and pneumatic power supply!
Danger of injury if the machine is started accidentally!
For the adjustments in this chapter the PFAFF 1296 two-needle machine is
illustrated. On the PFAFF 1295 single-needle machines various adjustments only
have to be carried out on one side, i.e. in the right-hand hook area. This is
referred to in the different chapters.
13.01 Notes on adjustment
All following adjustments are based on a fully assembled machine and may only be carried
out by expert staff trained for this purpose.
Machine covers, which have to be removed and replaced to carry out checks and
adjustments, are not mentioned in the text.
The order of the following chapters corresponds to the most logical work sequence for
machines which have to be completely adjusted. If only specific individual work steps are
carried out, both the preceding and following chapters must be observed.
Screws, nuts indicated in brackets ( ) are fastenings for machine parts, which must be
loosened before adjustment and tightened again afterwards.
