In this video, we explain how greasing an embroidery machine depends on how heavily it is used. Under normal conditions, we grease the machine once a year, while machines running about 35 to 40 hours a week may need greasing twice a year. We also point out that greasing is less frequent than oiling, since oiling should be done daily.
We then move to the first greasing point at the back of the bed arm, where the cam operates the trimming mechanism. To access it, we remove the four screws, take off the cover plate, and expose the cam. If needed, we slide the linkage slightly out of the way to make the channel easier to reach.
We carefully apply grease to the cam channel while rotating the hand wheel on the back of the machine so the entire cam is covered. We make sure not to over-grease this area, because excess grease can cause the piston in the track to stick and prevent it from releasing properly. Once the cam has a light film of grease all the way around, we wipe away any excess with a Q-tip, a rag, or a finger.
To finish, we make sure the linkage is back in place, set the cover plate back on the machine, and reinstall the four screws. The goal is simply to leave a thin, even film of grease in the channel and reassemble the area securely.
Before servicing the cam area, it helps to clear out buildup with GPI's embroidery cleaning supplies.
