Use only authorized Shindaiwa parts and accessories with your Shindaiwa unit. Do not make modifications to this unit without written approval from Shindaiwa.

ALWAYS make sure the cutting attachment is properly installed and firmly tightened before operation.

NEVER use a cracked or warped cutting attachment: replace it with a serviceable one.
