PLEASE KEEP STERILANTS AWAY FROM ALL MOVING PARTS AND ELECTRICAL CONNECTIONS!!
PLEASE DO NOT OIL THE BEARINGS.
Rotation of the motor isn’t as critical as ensuring you consistently have the motor rotating the same all the time (by putting the clipcord on the same each time). Also, it is best for a motor to have minimal stops and starts. Just like a lightbulb does better without being turned off and on frequently.
Average voltage is from 4-6, but please don’t exceed 7.
There are two adjustments on this machine. The impact screw, and upstroke knob. Both have locking set screws perpendicular to them. Make sure they are snug!
The impact screw on the a-bar hits the frame and gives the sharp impact. You should be able to hear it tapping lightly at 5 volts. It should barely touch when the cam is all the way down. If the machine is “mushy” and doesn’t hit as hard, turn the screw in slightly. If it is running too rough, you may need to back it out slightly.
The upstroke knob is on the rear of the frame, and also doubles as the top clipcord terminal. It doesn’t really make much of a difference until the machine is running over 6 volts (in most cases). Turning it up will help stabilize and smooth it out. It will also hit softer. If turned too much, it will bind up the a-bar, and sound rough. Turning it down will make the machine hit harder.
