• Look for belt damage as shown in the figure above.
• Look for worn pulleys as shown in the figure above.
With the machine in operation—Do not touch the machine. Look and listen:
• A belt can have some vibration and not cause damage. It is necessary to correct this condition
only if the vibration is large.
• 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. If you know how to do this work (for example, correctly align belts and pulleys), and
you want to do it, speak to your dealer or Milnor
®
for part numbers. Replace worn components
before you make tension adjustments.
• Machines that use rods with full threads and nuts to hold the position of the motor base—Turn
the nuts on the rods as necessary to adjust tension. Tighten the nuts.
• Machines that use a spring to hold tension on the motor base—Use the belt tension sleeve
supplied with the machine. Put the sleeve on the rod that the spring is attached to or remove
the sleeve to increase or decrease tension (see the figure below). Replace the spring if
necessary.
