Foreword
Thescope of this booklet is confinedto such instructions os are conditioned by
voriotions in the design of the new Pfoff 463 high-speed sewing machine as
compared with previous Pfaff high-speed seamers.
An outstanding feature of the Pfoff 463 is the incorporation of seaied-for-life
ball and needle bearings of the latest design which obviate the use of an
automotic lubrication system.
Another salient feature is the arrangement of the feed driving and feed lifting
eccentrics on the bottom rather than the arm shoft. The bottom shaft is driven
from the arm shaft by a Synchroflex belt and drives the hook shaft by means
of helical gears.
These driving elements are enclosed in an oiltight gear case and are lubricated
by means of an oil-soaked foam rubber sheet. The only part that requires
special lubrication is the sewing hook. Lubrication of this port is accomplished
by means of a reservoir oiling system incorporating acentrifugal switch.
Since the arm shaft is belted to the motor, the machine can be tilted bock
without removing the V-belt.
Additional features of the new high-speed seamer are a novel stitch length
control, separate forward-reverse feed control, built-in bobbin winder and
built-in lifting lever.
Operators will like the modern functional design and the streamlined belt
guard which is attached to the machine arm.

1. Setting Up the Machine
The Pfaff 463 drop-feed sewing machine, like the other models in the new
line of high-speed seomers, con be set up only on o power table fitted with
the new rubber hinge bracket and cushion set.
The front corners of the bedplate are face-milled on the underside and rest on
matching rubber cushions which are recessed into the tabletop.
At the back, the new-type hinge studs connect the sewing head to the pins in
the two rubber hinge brockets. This mounting prevents the machine from com
ing in contact with the tabletop.
The machine is carefully balanced and causes procticatly no vibration. What
ever vibration there is,will be absorbed by the rubber hinge brackets.

2. Mounting the V-Belt
The machines ore shipped with the belt guard removed.
To mount the V-belt, lift the sewing head slightly and place the belt on the
machine and motor pulleys.
Slightly turn out screws ol, a2, a3, and a4, and push the two belt guard
sections together, holding them close to the machine so that the above screws
enter the appropriate slots in the back wall of the belt guard.

To tighten the screws again, insert the screwdriver through openings bl, b2,
b3, and b4 (Fig. 2).
Both belt
guard sections ore secured to the vertical portion of the machine arm
by inserting screw d (Fig. 1) through holes b5 and c into screwhole dl and
tightening it securely,

3. Test-Running the Machine
Before you tesf-run the mochine, carefully remove all dirt which may have
accumulated in transit. Use only abrush and acleaning rag for this purpose.
The Pfoff 463 must never be rinsed or cleaned with kerosene because there is
a donger that the cleaning fluid enters the sealed-for-life bearings and dis
solves the greose. For the
same reason, kerosene or gasoline must not be used
for the
regular servicing of the machine.
Never attempt to eliminate hard working of the machine by squirting oil freely
into the bearings which, you believe, may be responsible for this fault. If oil
enters the sealed-for-life bearings, the grease will be thinned
and flung out of
the bearings, thus eliminating permonent lubrication.

4. Winding the Bobbin
The new high-speed seamer is fitted with a bobbin winder which is incor
porated in the face cover rother than mounted at the balance-wheel end, as
customary. Arranged at a convenient height, it is easy to operate end enables
the operator to wind bobbins
quickly and neatly.
The bobbin winder driving motion emanates from the take-up crank. When the
bobbin winder is engaged, driving crank F at the rear end of spindle 17 is
pushed into the circular path of stud K which engages the crank and in this
way drives the bobbin winder (Fig.3).
The bobbin winder spindle is carried in a self-lubricating sinter-metal bearing
which requires no additional lubrication. To engage the bobbin winder, simply
depress stop latch a located above the bobbin winder spindle (Fig. 5). This
action causes the spindle to move slightly to the right in which position it is

retained until sufficient thread has been wound on the bobbin. The thread
wound on the bobbin pushes the com up and thereby stops the bobbin winder.
The
amount of thread to be wound on the bobbin can be regulated by loosen
ing screw b and setting cam a higher or lower, as may be required. Set the
cam higher for more thread, or lower, for less thread.
Figs. 4 and 5show how to guide the thread to the bobbin winder.
Place the spool of
thread on spool pin 11 and bobbin 16 on spindle 17. Lead
the
thread from spool 11 up and through the top thread guide of the threod
stand, down to thread guide 12 on the rear arm cover, through thread retainer
13 below thread guide 2, through thread guide 14 and around thread tension
15 to bobbin 16.

To facilitate threading, if is recommended to wind a few clockwise turns on the
bobbin 16 first,
and then to lead the thread around thread tension 15. Depend
ing on the material to be sewn, the
thread should be wound tighter or looser.

The thread tension is regulated by turning thumb nut 18 back of the tension
discs. Turn the nut counter-clockwise for a tighter tension, or clockwise for a
looser tension.
If the threod should pile up at one end of the bobbin, adjust the position of the
tension stud. The set screw securing this stud in position can be reached from
below.
5. Threading the Needle
Because of the high speed of the seamer the smooth possoge of the thread to
the needle is especially importont.
Lead the thread from spool pin 1 up to the top thread guide of the thread
stand and down to thread guide 2. It is recommended to lead the thread first
through the vertical hole from top to bottom and then through the transverse
hole of the guide, as shown in Fig. 4 and 5, in
order to prevent it from snarl
ing up on the guide and breaking,
Now lead the thread through two or three holes of thread retainer 3, as may
be required, clockwise around and between tension discs 4, through thread
check spring 5, under stock threod regulator 6, through thread guide 7, from
right to left through the hole in take-up lever 8, through thread guides 7 and 9
and from left to right through needle eye 10.
6. Regulating the Stitch Length
The stitch length is regulated by means of stitch length control n (Fig. 6). The
large diameter of this control mokes for an exceedingly fine stitch length
regulation. When control n is turned by one tooth, the
stitch length is increased
by Vfii". The stitch length is indicated on the teeth in millimeters.
