Note: The 2750 and 2750 pro are the same machine with extra features bolted on. We have the non-pro version. The instructions are mostly the same between the models. The non-pro does not have a needle positioner.

'''Always power off the unit before any mechanical adjustments or threading.'''
'''Always power off the unit before any mechanical adjustments, accessory changes, needle changes, or threading.'''


'''Caution:''' '''The foot pedal WILL STILL OPERATE THE MACHINE for a few revolutions if the controller has recently been powered off.''' The servo controller will retain a moderate capacitor charge after powering off.  To drain this charge, firmly hold the hand-wheel while gently depressing the pedal - the motor will try to turn at low speed but will quickly run out of power. Once the capacitors are drained, the unit is safe to work on.

### Bobbin is mounted in a bobbin carrier - Thread should unwind clockwise when viewed from the 'underside' of the carrier. (Flip carrier to install bobbin - it makes sense in your hand)


==== Bobbin Winder ====
=== Sew your thing ===
Operates on the main machine belt: Always remove the thread from the needle before operating the bobbin winder to prevent a blockage
'''NEVER run the machine backwards.''' If you've gone forward enough to puncture your material with the needle, it's too late to go back. Finish that stitch. If you run backwards, you WILL wrap thread around the bobbin carrier and it will need to be unblocked involving some machine surgery.

Use the right pedal to lift the presser foot and release tension to install/remove your work piece.

Use the right pedal to lift the presser foot and release tension to install/remove your work piece.
Use the left pedal to sew. '''Sewing speed is variable starting at a minimum 400spm'''. If the controller is set higher, full deflection of the pedal will result in full set speed. Minimum deflection will always start at 400spm speed for brushless servo motor torque/control reasons.


Use the left pedal to sew. Sewing speed is variable down to a minimum 400spm. If the controller is set higher, full deflection of the pedal will result in full set speed. Minimum deflection will always start at 400spm speed for brushless servo motor torque/control reasons.
Hold tension on the loose thread ends towards the rear of the machine at the start of each first stitch.

==== Changing Feet ====
==== Install accessories/feet ====
Unscrew, Screw. USE THE RIGHT SIZE FLAT-HEAD SCREWDRIVER TO NOT MANGLE THE SCREWS.
Follow the video guides. Return machine to factory default when you are done.
 
Virtually every screw on the machine is flat-head. With the correct size screwdriver, these can and should be significantly torqued.  
 
'''USE THE CORRECT SIZE FLAT-HEAD SCREWDRIVER TO NOT MANGLE THE SCREWS.'''
 
==== Install/change needle ====
 
# Raise needle bar to highest position using the hand wheel.
# Hold existing needle to prevent it falling when loosened.
# Use a flat-head screwdriver to loose the needle set screw.
# Remove the old needle, and replace with new needle.
## Note: _______________
 
==== Bobbin Winder ====


==== Install accessories ====
* Operates on the main machine belt: '''the needle/feed will operate while winding the bobbin.'''
Follow the video guides. Return machine to factory default when you are done.
* Always remove the upper thread from the needle before operating the bobbin winder to prevent a blockage. Best practice is to unthread to before the take-up arm to prevent thrashing.
* Thread through the thread arm above, then winder tension guide hole (back right of table), tension disc, and forward to the bobbin.
* The bobbin winder will automatically disengage from the belt at about 80% full. Do not overfill the bobbin.
