10. To operate reactors equipped with an air motor, connect air hose to a compressed air
line. For best torque and speed control the piping to the motor should be at least 3/8" IPS or
larger. Fill the oiler with SAE 10 oil and adjust the oiler feed to a rate of one drop per minute
into the air stream. For long continuous runs at high speeds, the oiling rate should be
increased to three drops per minute.
If the motor becomes sluggish, flush it with a non-flammable solvent in a well ventilated
area. Disconnect the air line and muffler and pour a small amount of solvent into the inlet
port. Rotate the shaft by hand in both directions for a few minutes; then connect the air line
and run the motor until there is not further trace of solvent in the exhaust. If the muffler is
dirty, replace it. Re-lubricate the motor with a squirt of oil into the chamber and reassemble.
