Bobbins and hook
How is the bobbin case removed safely?
conditional
Turn power off and unplug, raise the needle and foot, remove the hook cover plate, open the hook cover, pull the case latch and take the bobbin case straight out; release the latch to drop the bobbin from the case.
This is the documented removal procedure; the adjacent exclusive-bobbin sentence names base model 1600P and does not establish a DB/DBX bobbin specification.
With power off, route thread through the guide behind the thread-guide bar, under the winding-tension disk, and through the bobbin hole from inside to outside. Align the notch with the spindle spring, seat the bobbin and move the stopper left. After setup is complete and hands are clear, turn power on, hold the free end and press the winding button for several turns; stop, cut near the hole, then restart. Winding stops automatically when full.
Complete all threading and bobbin placement with power off. Turn power on only after setup is complete and hands are clear; return the stopper, cut the thread and remove the bobbin when winding is done. The dedicated motor permits winding while stitching, but this does not relax the safe setup sequence.
Which direction and path does bobbin thread follow?
conditional
Place the bobbin so thread winds clockwise, draw thread through the case slit, under the tension spring and through the opening, and leave about 10 cm; it should spin clockwise when thread is pulled.
This procedure does not establish bobbin class, material, dimensions or MPN.
Hold the case latch open, align the case slot with the hook rib, release the latch to lock it, then close the hook cover before attaching the hook cover plate.
Keep power off and unplugged while the hook cover is open.
Turn power off and unplug, lower the foot, loosen the clamp, then insert the needle fully with its groove to the left and small scarf to the right before tightening firmly.
Use a straight, good-quality needle and preserve the DB x 1 system requirement.
With power off and the machine unplugged, raise the presser-foot lifter, loosen the setscrew, insert the documented replacement foot from the bottom, and tighten the screw with the large screwdriver.
This establishes only the documented screw-mounted replacement procedure, not generic or high-shank compatibility.
How should the hook and feed dog be cleaned and oiled?
conditional
With power off and unplugged, remove the needle, foot, hook cover plate and needle plate, then brush the hook and feed dog. For frequent use, oil daily with two or three drops of MO-70 at each illustrated location, wipe excess, remove the case before oiling the hook race, and sew waste fabric afterward.
Unplug before cleaning or oiling; the manual image, not this summary, controls the exact oil locations.

How is a bobbin wound?: With power off, route thread through the guide behind the thread-guide bar, under the winding-tension disk, and through the bobbin hole from inside to outside. Align the notch with the spindle spring, seat the bobbin and move the stopper left. After setup is complete and hands are clear, turn power on, hold the free end and press the winding button for several turns; stop, cut near the hole, then restart. Winding stops automatically when full.
How is the bobbin case installed?: Hold the case latch open, align the case slot with the hook rib, release the latch to lock it, then close the hook cover before attaching the hook cover plate.
Which way is the needle inserted?: Turn power off and unplug, lower the foot, loosen the clamp, then insert the needle fully with its groove to the left and small scarf to the right before tightening firmly.
How is the documented presser foot replaced?: With power off and the machine unplugged, raise the presser-foot lifter, loosen the setscrew, insert the documented replacement foot from the bottom, and tighten the screw with the large screwdriver.
