Cleaning The Feed Dog And The Sewing Hook; Removing And Replacing The Face Cover - Pfaff 260 Service Manual

Cleaning the Feed Dog and the Sewing Hook
lint is likely to accumulate on the underside of the needle plate and in the
vicinity of the sewing hook. Therefore, from time to time, strip the needle plate
and remove the lint accumulated on its underside as well as packed between
the tooth rows of the feed dog. At the same time, do not forget to clean the
sewing hook (Fig. 66).
Important
Use non-resinous and acid-free Pfaff sewing machine oil only. Never use ani-
mal or vegetable oils, for they are entirely unsuitable.
In general it may be said that the bearing surfaces of all moving and rotating
parts require regular lubrication. The oiling points are marked by arrows in
Figs. 61...05 and, hence, will be found easily.
To rinse the machine with cleaning fluid thoroughly, it is best to place it on a
stand. Provided proper caution is used, it may be rinsed even after it has been
mounted on a cabinet.
Here is the procedure to follow:
Tilt the machine back and squirt cleaning fluid into all oilholes marked by an
arrow in the pertinent illustrations. Use a separate oiler for this purpose.
Make sure that the clip belt does not come in contact with the cleaning fluid
or the oil, as this may cause hard running of the machine.
One or two drops of oil normally ore sufficient for each oiling point. Running
the machine for just a few minutes will suffice to work the oil thoroughly into
all the bearings. Excessive oiling will cause soiling of the work, the excess oil
forming residues which, together with the accumulated dust and lint, in time
will couse heavy working of the machine.
Removing and Replacing the Face Cover
The face cover normally need only be removed when the needle and presser
bars have to be adjusted or the ports at this end of the machine need clean-
ing. To do this, loosen set screw K (Fig. 63) and pull the face cover down, then
away from the machine.
Replacing the face cover is very simple because on PfafF 260 and 360 machines
no part of the needle threader mechanism is aHached to the face cover.
