13 Adjustment
The illustrations in this chapter show the PFAFF 1245 single- needle machine.
Various settings must be duplicated with the PFAFF 1246 two-needle machine,
i.e. in the left and right hook area.
An indication is given in the respective chapters where some illustrations are to
be considered as a mirror image.
Observe and comply with all instructions in the operating manual's chapter
1 Safety! In particular make sure that all safety covers are installed again
correctly after making adjustments, see chapter 1.06 Operating manual
hazard information!
Unless otherwise stated, the machine must be disconnected from the power
supply before all adjustment work!
Risk of injury due to accidental machine start-up!
Notes on adjustment
All adjustments in this manual are based on a fully assembled machine and may only be
carried out by technical 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 that have to be completely adjusted. Both the preceding and following chapters
must be observed if only specific individual work steps are carried out. Screws and nuts
indicated in brackets () are fastenings for machine parts, which must be loosened before any
adjustment and tightened again afterwards.
13.01 Tools, gauges and other accessories
O1 set of screwdrivers with knife widths from 2 to 10 mm
O1 set of wrenches with jaw widths from 7 to 14 mm
O1 set of Allen keys from 2 to 6 mm
O1 metal ruler (order no. 08-880 218-00)
