How to replace consumable parts
4. Conveyor
If significant looseness, contamination, or scuffing is found in the conveyor belt when performing the work
steps stated in"3.3 Inspecting and cleaning the conveyor belt" of Chapter 3, the conveyor belt needs to be
replaced. Follow the steps below to replace the conveyor belt.
Note that the conveyor belt replacement for dual-stage type machines differs partly depending on the
conveyor belt location. Also single-lane type machines and dual-lane type machines share the same belt
replacement procedure.

Put a mark at the tensioner position.
Before loosening the belt tension, put a mark to indicate the positions of the mounting bolts of the
