never force them over the side of the pulley. Always loosen the motor
to install them. Over tensioning of belts may cause premature failure.
5. When one or more of the belts is worn out, put on a COMPLETE set
of new belts.
6. A good way to check belt tension is to strike the belts with a clench
fist. A slack belt will feel dead under this test, whereas a properly
tensioned belt will vibrate and feel alive. Check the belt tension from
time to time. See Figure 11
Warning: Never run unit with belt guard removed and never check belt tension while
unit is running. Such unsafe practices can result in injury or death.
The working life and proper functioning of the belts depend to a high degree on how
they are cared for. Oil and grease will soon ruin them. Oily or greasy belts can be
cleaned with a good solvent.
