Please observe all notes from

Chapter 1 Safety

of the instruction manual! In

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.

On the

PFAFF 3822

no c-clamps may be attached to the needle bar as this

would damage the special coating on the needle bar.
