For
50-cycle
current
a
2,800
r.p.m.
motor
should
be
used,
while
a
3,400
r.p.m. motor is appropriate for
60-cycle
current.
The
motor
pulley
can be easily exchanged to alter the
maximum
sewing
speed
of the machine.
The below
table
should be consulted for all
data
regarding the maximum
number
of
stitches which
can
be
obtained
with
motor
pulleys
of
different
diameters.

Unpack
the head
cautiously
in
order to
avoid
damage to the
machine.
After
taking
off
the
lid
of
the
box,
unscrew
the
wood
screws
which
hold
the cushioned wooden blocks that support the machine head in the box.
Cautiously
lift out the head,
wipe
off the dust and
mount
it on the rubber
pads on the
table.
To
facilitate the
mounting
of the
V-belt,
slip
the belt
on the
machine
pulley,
slightly
tilt back the
machine
and
pull
the belt onto
the
motor
pulley.
Adjusting
the
V-belt
tension
is
instructed
in
Section
20.
The
machine
is dispatched
without
oil
In
the reservoirs and must not be
run
while
in
this
condition.
2. Filling
the
Oil
Reservoirs
The amount of oil
which
is needed for the first two
fillings
comes with the
machine in o can. The oil used in the
PFAFF
433 is a spindle oil with o
viscosity
of
110S/70»F
(US)
or
95R/70°F
(Br.)
which
has
proved
very
satis
factory for the
lubrication
of
high
speed
sewing
machines.
To
fill
the
main
reservoir take out screw d (Photo
1),
fill
in about one pint
(.5
I)
of oil obd
wait
a few minutes until it has drained down into the reservoir. Then
-check
the
oil
level
gauge to see if the
amount
of
oil
filled
up is
sufficient.
The
oil
level should be between the "max." and "min." marks when the machine
is inoperative.
Never
remove
the top cover to
fill
up
oil
there.
