Danger
If the rotary knife becomes worn or damaged,
a crack or tear between the sail and flat part
will result.
Since a piece of the rotary knife may break
and fly off while it is rotating, be extremely
careful.
Caution
When touching edged tools, wear gloves,
since they could cut your hands.
Caution
The rotary knife has a specific installation
direction.
Do not install the rotary knife facing the wrong
direction.
Important
Before installing the rotary knife, make sure
that it is balanced.
Important
The tightening torque for the knife mounting
