• Assembly: First fit the lower belt and then the
upper belt.
• Ensure the blades are positioned as set out in
the diagram, at 90 degrees to each other,
otherwise the belts must be adjusted. When the
blade bearings are loose the belts can be moved
around to the next tooth.
• Tighten the nuts enough so that the bearings rest
against the cutting hood but still can be moved.
IMPORTANT INFORMATION
The blades on a Bio unit should be set at
90 degrees to each other. In all other
cases the blades can collide and cause
serious damage to the cutting unit.
