Slippage of sheet arises in cutting.
Cause 1 : The pinch rollers and grid rollers fail to securely retain the sheet in position.
Remedy 1 : Check the position of the pinch rollers and grid roller and adjust them so that
they securely retain the sheet in position.
Cause 2 : The clamp pressure (high or low mode) has not been properly selected.
Remedy 2 : Select the adequate clamp pressure.
Cause 3 : The roller sheet is not wound with properly tensed and is slack. The sheet
meanders or becomes aslant at the time of the sheet feed.
Remedy 3 : Remove a slack of the roll sheet and straighten the right and left end faces of the
roll when loading the roll sheet on the device. Then, execute the sheet feed.
Cause 4 : The sheet has bent to come off the mount to have air bubbles between them.
Remedy 4-1 : If the sheet is to be cut longer, take care not to allow the sheet to bend while it is
fed or cut to avoid an extra load to the sheet.
Remedy 4-2 : If the sheet is to be cut longer, be sure to secure a sufficient space for working in
the direction to which the sheet is fed. (Front: 1.5 m or more Back: 1.5 m or
more)
Cause 5 : The sheet comes in contact with the floor surface. (The front end of the sheet is
cut aslant.)
Remedy 5-1 : Decrease the cutting speed (SPEED) to reduce the load to the sheet when it
contacts the floor surface.
Remedy 5-2 : If you use CG-60EX, use the optional stand or any stand that is equivalent to the
optional one.
Cause 6 : Side margins of the sheet at the location of the pinch rollers is inadequate.
Remedy 6 : Be sure to secure a side margin of 20 mm or more on each side of the sheet at the
location of the pinch rollers.
The device drags the tool during running.
Cause 1 : The sheet is warped.
Remedy 1 : Load the sheet on the device taking care not to warp it.
Cause 2 : The lifting/lowering of the tool is faulty.
Remedy 2 : Turn the power off and lift/lower the tool holder by hand.
If the tool holder does not go up but remains in the lower position, call your
distributor on the phone for maintenance.
