Pfaff 130 Service Tips
1. What I see most often when I get a machine in for service is that the
owner has over oiled the machine (or not oiled it at all). Over
oiling happens particularly with the motor. The oil that is used isn't
sewing machine oil which has a specific weight and viscosity that
makes it perfect for a sewing machine. Too much oil will ultimately
cause a build up of grime and cause components to wear faster. The
motor becomes gummed up and eventually does not make good
contact between the brushes and the commutator. So, I recommend
that the motor be oiled no more than twice a year using only ONE
DROP at the front and at the rear of the motor. If you are sewing every
day for several hours per day, oil the main moving components at least
once a week. Using the machine maybe a couple of times a week calls
for oiling once a month. Less use than this, oil once every 3 months.
Just use common sense when oiling and be prudent with how much oil
you use.
2. Always check your machine by turning the balance wheel by hand
every now and then to see if it is free and smooth. Most often people
tighten the motor belt much too tight. Loosen the motor bracket just so
the belt slips a little, then take a little slack out (just tighten a bit more)
then tighten the motor bracket. You may think it is going to slip but if set
correctly it won't. If it does just tighten it bit more.
3. Keep the rotating hook area clean from thread and fuzz. If this is
allowed to build up you will start having all sorts of problems from
skipping stitches to breaking needles.
4. If you discover some binding while the machine is running, it is most
likely caused by one of three things. The 'Dial a Stitch' cam is out of
adjustement (setting this is covered in the service manual), the front
needle bar is binding (you will notice this in zig zag mode). First
disassemble the side and front covers and oil the internal 'Dial a Stitch'
cam (just right of the fork), Lubricate the needle bar on all moving areas
(remember 1 drop only). Finally, binding is caused by 'thread lock'
Thread wrapped around the hook assembly). If you take the hook
assembly apart be very careful to insure where the screws go because
they are different sizes.
