It is important to keep the rotary hook area clear of lint & debris. Approx. every 40

hours of operation,

remove needle plate and blow clear with compressed air, turning the shaft to check all points. Also, ensure

the machine is always stored in a climate-controlled area. Temperature and humidity extremes can affect

the performance and even cause permanent damage.

Daily:

(or every 8 hours of

operation). Oil along the race of the

rotary hook (red arrow)

Weekly:

(or every 40 hours of operation). Oil upper & lower portions of

reciprocator & pressure foot shaft, and all needle bars through take-up lever slots.
