A belt must have sufficient tension that there is no slippage on the pulley during operation. If slippage occurs, you can usually tell from the noise. About Component Replacement and Tension Adjustment—Correct adjustment is very impor- tant to the service life of components and operation of the machine. Your Milnor ® dealer can do this work.
Connect chemical tubes only to chemical manifold inlets. � Stop leaks. Remove leaked supplies from surfaces. � ® Speak to your dealer or Milnor if you see corrosion damage. � CAUTION: High water pressure — can cause laundering chemicals to splash on per- sonnel and machine surfaces.

( ). Do this test at the intervals given in the maintenance summary. Definitions: 3-wire circuit a series electrical circuit on a Milnor ® machine that must close before the ma- chine can operate. If a switch in the circuit opens, machine movement stops and the operator alarm (a buzzer and a display message) comes on.

2. With your body weight, compress the length of the shock absorber against a hard surface. A serviceable shock absorber compress slowly. It will also expand slowly to its initial length when you release it. If it compresses or expands quickly, the shock absorber is bad. Pellerin Milnor Corporation...
