HOOK
LUBRICATION
The
bobbin
case
raceway
is
lubricated
by
oil
pumped
from
the
hook
saddle
reservoir
while
the
ma-
chine
is
operating.
The
amount
of
oil
received
by
hook
raceway
is
very
important.
To
check
this,
first
remove
bobbin
case.
Then
with
the
machine
running,
hold
a
small
piece
of
white
paper
near
the
hook
for
about
10
seconds.
A
distinct
spray
of
oil
should
be
visible
on
the
paper.
If
there
is
no
trace
of
oil
or
an
excess
of
oil
on
the
paper,
proceed
with
the
following
steps:
l.
Tip
machine
and
loosen
control
valve
set
screw
shown
in
Fig.

and
return
machine
to
upright
position.
2.
Turn
control
valve
screw
shown
in
Fig.
7
clock-
wise
for
more
oil;
counterclockwise
for
less
oil.
Re-tighten
control
valve
set
screw.
A
short
test
run
of
at
least
a
minute
should
be
made
between
adjustments
to
insure
uniform
oil
flow.
After
each
adjustment
of
oil
control
valve
screw,
oi I
control
valve
set
screw
should
be
securely
tightened.

DISTANCE OF NEEDLE BAR FROM PRESSER BAR
(211Gl5l AND 211Gl57)
The distance between needle bar and presser bar
(after regulating stitch length so that there is no feed
movement) should be 17 /32 inch as shown in Fig. 24.
If
the di stance between needle bar and presser
bar is more or less than 17 /32 inch, first turn ma-
chine pu 11 ey over toward you unti I need Ie bar is at
highest position. Remove cover plate from front of
machine arm after removing screw (directly behind
cover plate) in rear of machine. Loosen needle bar
frame clamp screw shown in Fig. 25. Move needle
bar frame forward or backward to correct its position.
Re-tighten clamp screw.
Distance between needle bar and presser bar should be
37 /64" (14,68 mm) in the case of 211 G 158 machines.
REVERSE FEED MECHANISM (2l 1Gl57)
To reverse feed direction by hand, push reverse
lever completely down in order to have same stitch
length as in forward stitching position.
To reverse the feed with foot treadle, the foot
treadle chain should be connected to hole in reverse
feed lever shown in Fig. 26.
Release hand lever or foot treadle only when you
wish to resume forward stitching.
ADJUSTING FEED REVERSING MECHANISM
Adjust stitch length to 5 stitches per inch. Loosen
screw A and adjust crank shown in Fig. 26 so that
needle will penetrate fabric 5 times in each inch of
stitching. When you depress the reversing lever, the
eccentric head of the bearing pin B should rest a-
gainst the bearing block. Loosen set screws C and
turn bearing pin B unti I the stitch length is the same
in reverse feed as in forward feed. Tighten all screws.
211G158 only
The maximum stitch length of approx. 10 mm is being
limited by the Feed Reversing Shaft Crank Hinge Stud Stop
.A".Fig.26A.ln reverse feed the stitch length Is only approx.
1/3 of the forward feed stitch length.

Regulate stitch length so that there is no feeding
motion.
Remove throat plate and turn machine pulley over
toward you until lower timing mark on needle bar is
just visible at lower edge of needle bar frame on up-
ward stroke of needle. With needle in this position,
sewing hook is correctly timed if hook point is at
vertical centerline of needle blade.
If sewing hook is not correctly timed, loosen socket
screws shown in Fig. 30 and turn to proper timing
position specified above.
REMOVING BOBBIN CASE FROM SEWING HOOK
Remove hook gib screws, indicated in Fig. 3l(a),
from sewing hook. Lift off hook gib and remove bobbin
case.
REMOVING SEWING HOOK FROM MACHINE
Remove presser foot, throat plate and feed dog.
Loosen hook hub socket screws shown in Fig. 32.
Lift hook off end of shaft.
To remove hook shaft, first remove ball bearing
retaining cap screws directly under hook shown in
Fig. 31(6). Tip machine back and loosen hook shaft
gear hub socket screws shown in Fig. 30. Lift out
shaft from top end. If shaft does not lift out easily,
loosen screws in cover plate of hook saddle just
