5. Environment Requirements
1. Keep the motor and control box away from high magnetic field environments and radiation
environments to avoid malfunction.
2. The work environment temperature must be in the range of 5 –45 °C.
3. Don’t use this product next to heat sources (such as radiator).
4. Don’t use this product in a too humid environment.
5. Don’t use this product near to corrosive liquids and explosive substances.
6. Always keep ventilation for the control box and motor to ensure good heat output.
7. Keep the power input voltage stable.
8. Make sure there is a reliable earthing device for the system.
6. Troubleshooting
If the machine can not work very well, maintenance and repair must be operated by
professionally trained personal.
Fault 1: The display does not light up when the power is turned ON.
Check if the power plug is connected to the socket properly.
Check if the protective fuse is broken. If it is broken, replace the fuse with a new one
(5 A / 250 V Ø5 x 20 mm). To check and replace the fuse, open the cover of the control box
(see picture).
Picture 5
Fault 2: The display lights up but the motor does NOT run when pressing the pedal.
Check if the connections of the speed control unit plug, the motor plugs and the synchronizer
(if applicable) are connected properly. If yes, check if the speed control unit switch is good.
Fault 3: The speed of the motor is not stable.
Check if the V-belt tension is good. If the V-belt tension is too loose, the motor pulley (and /or
machine pulley) can slip over the V-belt. Also check the input power if it is stable.
Fault 4: The motor stops running by itself.
Check if the machine load is too heavy (material too heavy) or if there is a mechanical blockage
on the machine. Then check and make sure all plugs are connected properly. If all above is
good, check if the display is showing “E1” or “E2”. If so, this motor stop is self protection. The
control box needs to be restarted.

Fault 5: The motor keeps running by itself when the power is turned ON.
Check if parameter M is set correctly. When parameter M is set to 1 but NO synchro is used the
motor will start to run automatically when the power is turned ON. For use WITHOUT synchro
parameter M must be set to 0.
If parameter M is set correctly, check if the position of the magnet on the end of the swinging
arm inside the speed control unit is good. This magnet moves across a Hall sensor on the
electronic board to vary the motor speed. Do this the following way:
1. turn OFF the power of the control box
2. open the plastic cover of the speed control unit and loosen the bolt of the swinging arm.
3. move the swinging arm in the position of picture 6
4. turn ON the power of the control box, take care not to touch the electronic components on
the electronic board.
5. move the swinging arm back in the direction of picture 7, first the speed will go up but as
soon as the magnet goes over the Hall sensor the speed will go down again.
6. At the point where the motor stops running, secure the bolt of the swinging arm.
7. put the cover of the speed control unit back in the original position and secure the screws of
the cover.

Fault 6: The display shows “E1”
“E1” means the motor has an operational failure, check if the sewing material is too heavy, the
machine is stuck or some other reason that makes the load heavier. Also check if all plugs are
connected properly and check the pins inside the plugs (pin drawn back).
Fault 7: The display shows “E2”
“E2” means the motor has an over-current or under-voltage failure. Check if the power supply if
the range is within 200-240 Volts.

Fault 8: The display shows “E3”
Turn OFF the power of the control box, wait 10 seconds and turn the power back ON.
Fault 9: The fuse is blown as soon as the power of the control box is turned ON.
If the problem can not be solved by replacing the fuse contact your distributor.
Fault 10: Any other problem
If there is another problem that can not be solved, contact your distributor.
Additional remarks:
When the control box does not work properly, in the normal mode press the S button for 3
seconds. The control box will now be reset and show “O” and “K” when ready. After the reset,
try again.
