10.02 Programmed sewing
In programmed sewing a difference is made between fi xed programs (program numbers 1
and 2) and freely programmable sewing programs (program numbers 3-99).
The fi xed programs are are used for the quick and easy production of seams with different
number of stitches or fullness. The respective 2 or 3 seam zones are switched using the
knee switch function, see also chapter 7.07 Knee switch.
The fi xed programs are also designed as running programs and can be concluded by the
pedal function, see also chapter 7.04 Pedal.
The freely programmable sewing programs (program numbers 3 to 99) can be entered,
altered or deleted if necessary, see chapter 11 Input.
After the machine has been switched on (chapter 7.01 Main switch) and the programmed
sewing mode key has been selected with the PM key, the display appears for selecting the
program number, seam zone and stitch length.

If other functions are switched on, for example backtack functions, maximum seam
zone speed or stitch count, the scroll key can be used to switch between other menu
displays, for example, for entering the values in the corresponding seam zone and stitch
count.
The number of backtack stitches is set in manual sewing mode, see chapter
9.08 Entering the start and end backtacks. The values entered apply to all
seam programs.

.01 Maintenance intervals
Cleaning ........................................................daily, several times if in continuous operation
Clean the hook area ......................................daily, several times if in continuous operation
General oiling ...................................................................................... daily, before start-up
Oil the hook ......................................................................................... daily, before start-up
Oil level (thread lubrication / hook lubrication) ............................................... twice a week
Lubricate the bevel gears ..................................................................................once as year
These maintenance intervals are based on an average running time of a single
shift production shop. Shorter maintenance intervals are recommended for in-
creased running times.
12.02 Cleaning the machine
The required cleaning cycle for the machine depends on the following factors:
Single or multi-shift operation
Dust formation caused by the workpieces
Optimal cleaning instructions can therefore only be determined on a case-by-case basis
Disconnect the machine from the electricity mains for all cleaning work by
shutting off the main switch or removing the mains plug! Risk of injury due to
accidental machine start-up!
The following tasks are recommended
5 mm

Fig. 12 - 01
Make sure that the horn 3 engages in the groove of the stitch plate when inserting the
bobbin case.
Screw on the hook gib 1.
Insert the bobbin case with bobbin.
Clean the pinion 4.
Close the post cover.
during single shift operation to avoid
operational errors:
Clean the hook area
Clean the hook area with a brush.
Clean the hook
Open the post cover.
Bring the needle bar to the top position.
Remove the bobbin case sewing head
with bobbin.
Unscrew the hook gib 1.
Turn the handwheel until the tip of the
bobbin case 2 has penetrated approx.
5 mm into the groove of the hook race
Remove the bobbin case and clean the
hook race with kerosene.
86
Always operate the machine when the post cover is closed!
Risk of injury from the rotating hook!
Page 87
Maintenance and Care
12.03 Oiling the hook
Switch off the machine!
Risk of injury due to accidental
machine start-up!
Open the post cover.
Bring the needle bar to the top position.
Add a few drops of oil onto the hook race
at initial start-up or if the machine has
been standing still for a prolonged period
of time (see arrow).
Only use oil with a centre viscos-
2
/s at 40 °C and a
Fig. 12 - 02
ity of 22.0 mm
density of 0.865 g/cm3 at 15 °C!
We recommend
PFAFF sewing machine oil,
order no. 280-1-120 144.
12.04 Oil reservoir for hook lubrication
1
2
Fig. 12 - 03
Check the oil level before every
start-up.
Oil must always be visible in
the sight glass 1 and 2.
Add oil through the hole above the sight
glass as needed.
Only use oil with a centre viscos-
2
ity of 22.0 mm
/s at 40 °C and a
density of 0.865 g/cm3 at 15 °C!
We recommend PFAFF sewing machine oil, order no. 280-
1-120 144.

Maintenance and Care
12.05 Lubricating the bevel gears
1
Fig. 12 - 04
Switch off the machine!
Risk of injury due to accidental machine start-up!
Fresh grease should be applied to all bevel gears once a year.
Tilt back the machine sewing head and let it rest on the sewing head support.
Fig. 10-04 shows the PFAFF 1574 bevel gears.
To return the machine sewing head to its upright position, press the anti-tipping device 1
backwards and return the machine sewing head to its upright position using both hands.
Return the machine sewing head to its upright position using both hands!
Risk of injury by crushing between the machine sewing head and the table top!
We recommend PFAFF sodium soap grease with a dripping point of approx.
150 °C. Order no.: 280-1-120 243.
