Setting the Clamp High/Low Mode
The sheet clamping pressure can be switched between high mode and low mode using the clamp pressure lever.
Select high or low mode to suit the sheet being used.
- The clamps at each side must always be used set to high mode. The sheet may become skewed if the clamp mode is not correctly set.
- Set the clamp high/low mode once the pinch rollers have been positioned.
Clamp pressure lever | Use |
|---|---|
High mode | Cutting PVC sheet |
Low mode | To reduce pinch roller marks |
- When using low mode, the sheet may become skewed depending on the sheet type, feed rate, and sheet width.
Enabling and Disabling the center clamp
Disabling the center clamp allows the middle pinch roller to be used in the raised position.
Raising the middle pinch roller provides the following benefits:
- No marks are left on the sheet.
- Prevents the sheet from lifting up.
Enable or disable the center clamp to suit usage.
Be sure to push back the clamp lever to raise the pinch rollers before enabling or disabling the center clamp.
Three pinch rollers should always be used when using the maximum sheet width of the machine. Enable or disable the center clamp as necessary for the middle pinch roller.
If only the right and middle pinch rollers are used, the maximum sheet width cannot be used, as the middle pinch roller cannot be moved as far as the left edge of the left grit roller, as shown in the following figure.
- When using three pinch rollers, set the number of pinch rollers to "3" regardless of whether the center clamps are enabled or disabled.
