TLC for Power Tools

See to Those V-Belts

• Cracks. If the machine vibrates as it shuts down, that could be a sign of belt problems. Check the belt, or belts, and replace any that are cracked. Always buy one of the same series and length. If the marking has worn off the old belt, take it to a supplier as a reference. You can find local belt suppliers under "Power Transmission Equipment" in the Yellow Pages of your telephone book.
• Tension. When you tap a belt with your hand, it should feel taut, not slack. If you push on it lightly, it should flex about 1/32" for every inch between the pulley centers. Adjust tension according to the manufacturer's instructions.
• Performance. Spray a commercial belt dressing on the belt while the machine is running. This product reduces slippage and extends the life of the belt.
• Pulleys. Make sure they're aligned properly with one another and tight on their shafts. Use Loc-Tite, available at hardware stores, on the threads of set screws to keep them secure.
