SAFETY RULES
CAUTION!
THIS SAFETY SYMBOL INDICATES YOUR PERSONAL SAFETY IS INVOLVED
TO PREVENT PERSONAL INJURY:
All power sources to the machine MUST be TURNED OFF before threading, oiling,
adjusting or replacing parts.
Wear safety glasses.
All shields and guards MUST be in position before operating machine.
DO NOT tamper with safety shields, guards, etc., while machine is in operation.
LUBRICATION
IMPORTANT: Machine must be in a leveled position.
Oil has been drained from main reservoir before shipment. Use a straight mineral
oil with a Saybolt viscosity of 90 to 125 seconds at 100 degrees Fahrenheit. This
is equivalent to UNION SPECIAL Specification No. 175. Remove oil filler cap (A,
Fig. I) and fill to TOP line of oil level gauge (B). Replace oil filler cap.
CAUTION! On new machines, machines that have been out of service for an extended
period of time OR machines that have been drained of oil and refilled ...
run machine slowly at 300 R.P.M. for approximately five minutes while
paying strict attention to the oil flow indicator which should rise in
the oil filler cap (A) and remain steady while machine is running. This
must be noted to ensure that oil flow indicator is functioning and oil is
circulating. Run machine and recheck oil level which MUST be maintained
between the red lines of oil gauge.
To maintain maximum recommended speed and serviceability of these machines~ refer
to General Preventive Maintenance Schedule. Under no circumstances, should oil
remain in the machine for more than one year. Two oil drain plugs are located in
bottom of oil pan. ALWAYS replace oil filter when oil is changed. To replace
filter remove four screws (C, Fig. 1), cover (D) and lift out filter, REMOVE
(brass) BY-PASS VALVE FROM TOP OF OLD FILTER AND INSTALL IN NEW FILTER. Reassemble
in reverse manner.

TIMING FEED TO NEEDLE
Adjustment waul d be required if machine is
feeding while the needle or needles are in
the work.
To adjust; remove top cover~ head cover and
all other plates~ supports and covers as
required to provide accessibility to the feed
mechanism chamber. Turn handwhee 1 in
operating direction to position needle bar
connection (A, Fig. 2) at TOP of stroke.
Loosen four screws (A, Fig. 3) in upper
mainshaft sprocket (B) and hold handwheel so
upper mainshaft and needle bar cannot move.
While holding handwheel firmly, turn lower
mainshaft to position feed crank
counterweight (A, Fig. 4) with its FLATS
perpendicular to the bottom of machine and
facing away from the operator, as viewed in
Figure 4. TORQUE screws (A, Fig. 3) to 36
in-lbs (41 em/kg).
NOTE: Whenever "TIMING FEED TO NEEDLE" is
corrected, always check

SYNCHRONIZING
LOOPER AND NEEDLE MOTIONS."
SYNCHRONIZING LOOPER AND NEEDLE MOTIONS
Looper drive belt (A, Fig. 5) has proper
tension if, when turning handwheel in
operating direction to position looper in the
center of its (right to left) travel ... there
is no noticeable (right to left) play in the
looper mechanism.
There should be approximately 1/8 inch
(3.2mm) deflection in looper drive belt when
pressing firmly with thumb, midway between
sprockets (B and C). Adjustment can be made
by loosening two screws (D) and turn looper
module (E) clockwise (as viewed from
handwheel end of machine) to tighten belt
tension or counterclockwise to loosen belt
tension.
It is easier to rotate looper module by
turning cast-off plate mounting bracket (F).
At this time, notch (G) on end of looper
module should be facing in the upward
position (between 9 and 3 o'clock). Loosen
binder screw (H) and reposition cast-off
plate mounting bracket (F) so its leading
edge {J) is vertical to and parallel with bed
casting. Retighten screw (H) assuring that
the right side of mounting bracket is flush
with right side of looper module. Retighten
screws (D).
