Pfaff 269 - Page 2

General
It is recommended to run the Pfaff 268 and 269 at a maximum speed of 2300 s.p.m.
When sewing tightly woven and heavily dressed materials, the sewing speed should be
reduced in order to prevent the needle overheating.
To avoid trouble in the mechanism, run the machine at about 75 per cent of its top speed
until all parts in movable contact have become thoroughly glazed by their action on one another.
This should normally be the case after about two weeks' constant use.
All machines are shipped with the balance wheel disengaged. To engage the wheel, hold it
steady with your left hand and turn the large stop motion knob clockwise with your right
hand.
The presser foot is raised by means of a hand lever (on the back of the machine head).
On machines equipped with knee lever (special version) the presser foot can also be raised
by means of this lever.
Fundamentals of machine operation
Before you put the machine into operation for the first time, carefully remove all dust, then oil
the machine thoroughly (Section 3).
Use a resin- and acid-free sewing machine oil only.
Check to make sure the finger, take-up lever and belt guards are properly fitted.
Never run the machine unless you have fabric under the presser foot.
Before you start sewing, lay both threads back under the presser foot.
To prevent thread jamming, hold both thread ends until the machine has made a few stitches.
Do not pull the material during sewing: the machine will feed the fabric automatically.
Use System 130 R needles only.
Never use rusty needles.
Use high-quality thread only.
Always bring the take-up lever to its highest point before you remove the material.
Cleaning and oiling
Careful cleaning and regular oiling will increase the service life of your machine.
On new machines take a clean rag and remove the grease from all bright parts. Apply a
few
drops of kerosene to all oiling points marked with arrows in Figs. 1, 2, 3 and 4,
raise the presser foot, unthread the needle, remove the bobbin case, and let the machine
run briefly. Following this, apply a few drops of resin- and acid-free oil to all points
of friction shown in Figs. 1, 2, 3 and 4. Only use oil with a viscosity of 41.4 mm^/sec.
at 20° C and a density of 0.84 kg/dm^. We recommend using Pfaff sewing machine
oil No. 280-1-120122.
While these points of friction should be oiled twice a week, the sewing hook must be oiled
each day the machine is in operation.
