PREFACE
This semi-industrial sewing machine makes a single needle lock stitch and is equipped with a
high lifting, independent upper and lower feed mechanism. It
is intended for stitching medium,
heavy,
and extra heavy cloth, canvas, upholstery materials and light leather.
This Mini-Walking Foot sewing machine's feeding mechanism is composed of upper and lower
feed dogs which are synchronized to feed the material either forward or reverse. Both·lifting and
feeding feet alternatively press the material tightly together, permitting even stitching.
Remark :This instruction manual is commonly applied to our series of mini WC~Iking
foot sewing machine, which refers to straight sewing model and zig zag sewing model.

SPEED OF MACHINE
The maximum speed recommended for this machine is 900 RPM or "stitches per minute". Use
regular house-hold circuit 115 Volts, 60HZ. The machine is equipped with a one tenth (1/10) HP
motor with red..;ction pulley to provide good power at the recommended speed.
This sewing machine can be mounted
on a commercial stand. To do so, requires a special cut-out
table top, a one inch (1 ")diameter pul/y,, a special Balance Wheel Item No. 11, and a maximum
1725 RPM motor.
OILING
Before operating, oil all "metal to metal" working parts, and at the places indicated. Use only
genuine sewing machine oil. Operate the machine briefly on scrap material after oiling to prevent
soiling the v;ork. Frequent oiling is recommended.

PREPARE FOR SEWING
Thread the machine. Then pick up the bobbin thread as follows:
(1) While holding the loose end of the needle thread in your left hand, turn the balance wheel
toward you by hand until the needle moves down and up again to its highest point.
(2) Pull the needle thread gently, and the bobbin thread will come up with it in the form of a loop
through the needle hole.
(3) With your finger, pull this loop until the end of the thread appears. If the bobbin thread does
not rise, check
to see if at least 5 or 6 inches of bobbin thread is hanging loosely from the
bobbin case.
TO START SEWING
(1) With the needle raised, lay the lower or bobbin thread straight back from the needle hole.
(2) Place the material to be sewn under the presser feet and lower them onto the material.
(3) Hold the upper or needle thread (threaded through the eye of the needle) with the fingers of
the left hand.
Turn the balance wheel toward you with your right hand until the outside presser
foot reaches its most backward position.
(4) Now operate the knee or foot control to start sewing.
The above procedure is necessary
so the motor will start the machine to sewing. Do not help
the feeding of the machine by hand, as this may bend or break the needle. Also, damage i6.
the hook can occur.
The machine may run a little slow when ies
new. However, it will begin to "free up" and run smoothly
with continued use.
During operation, the balance wheel of the machine always turns toward the operator. To avoid
tangled thread and jamming of the sewing hook, do not turn the balance wheel backward (away
from the operator).
WARNING: Never operate the machine without material under the presser feet. Your machine will
probably "lock" and cannot be operated until the thread is cleaned out of the hook race.

TO REGULATE THE LENGTH OF STITCH
Most sewing will be done with the maximum stitch length. However, the length of the stitch can
be adjusted
as follows:
(1) Loosen the thumb nut on the stitch length lever.
(2) Raise the stitch length (feed regulator) lever until the desired stitch length is obtained.
(3) Tighten the thumb nut.
REVERSE SEWING
To sew in reverse:

Forward Feed
Reverse Feed
(1) Lower the feed regulator (stitch length) lever all the way to the bottom of the slot in the stitch
length plate.
(2) Hold the lever there until reverse sewing is completed.
(3) Then return the lever to the forward position.
