• Look for worn pulleys as shown in
With the machine in operation—Do not touch the machine. Look at the components and
listen to them:

• 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.

How to Find a Worn Pulley
1. Broken cord—damage from a sharp object.
2. Cracks—The belt is too large for the
pulley.
3. Shiny side walls—oil or grease on belt.
4. The belt layers disconnect—Oil or grease.
5. Bands on side walls—dirt, particles.
6. Incorrect: The pulley is too worn.
7. Correct: The belt only touches the side
walls. You can put a thin strip of paper into
the space between the belt and the pulley.
