BWC Hydraulic Feed Wood Chipper
Adjusting Drive Belt Tension
Before operating the wood chipper, check the condition of the drive belt. The belt should be free of cracking
and or defects. Replace the belt as needed.
Belts will stretch over time and require adjustment.
Follow these steps when checking the tension of the belt.
1. If the PTO is attached, disconnect it from the machine. This will allow the rotation of the belt and
pulleys.
2. Check the tension by pressing on the belt with your finger. The tension on the belt should be
firm with no slack. A loose belt can come off the machine and cause harm to the operator and
possible damage to the machine.
3. The belt tension can be adjusted by turning the nut on the idler eyebolt. Increase the pressure on the
belt if there is too much play. Decrease the pressure on the belt is too tight.
4. The proper amount of belt deflection should be approximately 1/8" as shown below.
