Adjustment

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.

13.01Notes 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.
