1. SafetCinstructions
The following must be observed for safety
0 Make sure belt cover is installed so as to prevent accidents.
0 Only use those electrical parts or components suitable for the
voltage in use. The use of incompatible parts or components may
lead to excessive heat buildup and eventual burnout.
0 Before performing any adjustments or maintenance on the
machine, such as cleaning, threading, or replacing the needles,
make sure the power is turned off and the motor is not running.
0 Always turn the power off when leaving the machine unattended.
0 Clean the air filter and discharge the drain of the air regulator on a
regular basis. If not done on a regular basis the drain may overflow
into the solenoid valve or air cylinder resulting in machine failure.
2. fNeedies
Recommended Needles:
In order to ensure proper sewing of your RX-Series machines we recommend that you use either
Schmetz or Organ brand needles system UY128GAS. Depending on what kind of fabric and thread you

Replacing Needles:
Please observe the following steps in replacing needles.
Step 1.
Turn off the switch (1) under the machine table.
Note:In the case of a clutch motor being used the
motor will continue to rotate due to inertia after
the power supply is turned off. If the pedal (2) is
stepped on inadvertently the machine will move.
Before attempting to replace the needles step on
the pedal (2) until the machine comes to a
complete stop.
Step 2.
Loosen screw (3) by using the alien key found in
your RX tool kit.
Step 3.
Remove the old needle using a tweezer.
Step 4.
Insert the new needle facing its scarf towards
the rear of the machine. Refer to Fig. 2-D.
Step 5.
Refer to Fig 2-E. Make sure the new needle is
inserted into the needle hole so that the needle is
in as far as it can go.

In the case of wooly thread refer to the diagram
shONwing the needle tension moved to bracket above
the needle clamp.
E=Looper Thread
To adjustthe cover thread eyelet, loosen screws (D) and adjust to the proper height:
As the cover thread take up is in its highest position, the bottom of the slot of the cover

5. Handwheel Direc^lpnd Operating Speed
Break In Period
For the first 200 hours of use The RX Series of machines should be run at approximately 5,000 R.P.M.
This speed is approximately 15-20% below maximum speed. This is required to allow the machine to
break-in before operating at full capacity.
Pulley Direction
(Refer to FiglO)
The direction of both pulley (A) & handwheel (B)
is clockwise as seen in figure 10.
