Follow directions supplied with the machine as to oiling and proper size of needle, thread, etc. Do not make any adjustments unless you are sure you know how. These adjustments require patience, as the adjusting screws must be turned a very little at a time to note the effect produced. Do not run the machine at too high a speed as this will shorten its life.

When putting a motor on a foot-power machine be sure that the old machine is not over-speeded.

If your machine is provided with a foot release be sure that the release entirely cuts off current, otherwise the motor will run very hot.
