3.3 Inspecting and cleaning the conveyor belt
Inspect the conveyor belt for wear. As the belt wears away, slippages may occur that prevent securely
conveying the boards. It is therefore necessary to make periodic checks for wear of the conveyor belt.
Belt wear may also cause trouble such as erroneous detection of the conveyor sensor due to dust from belt
wear accumulating on the sensor surface, or dust from belt wear accumulating in the belt guide grooves may
cause the belt to stick, etc.
