Product stuck in the product holder – not feeding properly	Stop machine Remove all product Check product and tube size (1/8” clearance all around the product)
Blade not tracking properly	Check blade guide for product residue (or anything else that may be in the slot) Check for adequate water supply & flow Retrack the blade and check for proper tracking
X-Gap not set correctly	Check blade tracking Reset x-gap according to the chart in the manual

Improper product holder height	Proper height no less than 1/32” and no more than 1/16” from the bottom of the holder to the blade
Excessive stroke	Going more than 1/8” past the leading edge of the blade guide opens the space between bottom of the tube and the tray and promotes more scrap
