Bobbin Area:
- Oil the bobbin area daily before production. During continuous use, re-oil every three to four hours.
- Remove the bobbin. Apply 3–5 drops of oil at the 11 o’clock position.
- Apply a few drops at the 1 o’clock position using the oil bottle from the toolbox.
- This area is in constant motion; heavier oiling is acceptable.
Needle Plate Area:
- Move behind the needle plate to locate the next oil port.
- Apply approximately three drops daily and every three to four hours during continuous use.
- Open the cover and remove the plate by sliding it to the right.
- Oil all 15 needle springs. This is a daily step only. Apply roughly three drops per spring.
- As the needles operate, oil will drip into the pad below, which should remain well-saturated at all times.
Reciprocating Area:
- Set the machine to needle one.
- Locate two small holes in the reciprocating area and add 2–3 drops of oil. Perform this every other day.
- Lubricate T-bars where the head slides left and right whenever they appear dry, typically every other day.
- Apply three drops to the small hole inside the head that feeds the reciprocating area. Perform this every other day.
- Identify three additional round holes in the reciprocating system. Apply 2–3 drops per hole every other day.
Main Shaft:
- Locate the oil point at the back of the machine. Apply approximately three drops daily.
White Lithium Grease Application:
- Move the bar to expose one side at needle one, then move to needle fifteen to expose the opposite side.
- Apply white lithium grease evenly until the surface appears fully coated and white, not dark or dry.
- At the top of the head, remove two Phillips screws and the cover to access the wheel.
- Apply grease to the center and screw area. Rotate to expose the other side of the wheel and grease accordingly.
- For the small pegs in this area, apply small dabs of grease between the pegs. Needle one exposes some pegs; move to needle fifteen to access the remaining pegs.
All oiling points and grease applications outlined above comprise the standard routine maintenance for SWD machines.
