1.3. Accessory Description
The Non-Mandrel Pipe Bender Limit CC90 is an accessory specifically designed to position the pipe or
profile during bending.
The CC90 limit makes it possible to produce serial parts faster with more precision and repetitiveness.
• Adjustable longitudinal positioning with 6 positions
• Angular head rotation every 5 degrees
• Adjustable four-hook tray for round and square pipes
• Longitudinal movement with high-precision linear guides
• Automatic anti-collision control
• Easy handling and preparation for complex parts

2. TRANSPORT AND STORAGE
2.1. Transport
The limit should be moved as follows:
- Along the bottom through the pallet at the base of the box using a forklift or lift truck as indicated in the
illustration. Never raise the limit more than 200 mm off the ground or it may tip over.
Figure 4. Moving the Limit
2.2. Storage Conditions
The Pipe Bender Limit may not be stored anywhere that does not meet the following requirements:
- Moisture of 30-95%
- A temperature of -25 to 55ºC or 75ºC over periods not to exceed 24 hours (please remember these
temperatures are for storage conditions)
- Do not pile heavy objects on top

- 10 -
ATTENTION: To grease the Limit, you must stop the machine and press the “Emergency Stop” button.
3. MAINTENANCE
3.1. Greasing the Moving Parts
Keeping the moving parts on the limit clean is recommended to ensure proper operation and extend the
service life.
To grease the limit skids on the CC90, simply grease all the limit greasers: 8 in all, every 30 days .

ATTENTION: The limit moves while the machine does the bending. Do not place anything in the Limit
work area that may obstruct its movement.
4. LIMIT LOCATION AND INSTALLATION
4.1. Limit Location
Try to position the machine and limit in the proper location so they do not have to be moved; otherwise,
follow the steps described in the Transport section (no. 2). Position over a smooth, level surface to prevent
vibrations and movements during bending operations .
4.2. Dimensions and Work Area
Take the dimensions, limit work area and the lengths of any part to be worked into consideration when po-
sitioning the limit.
The pipe bender may be used by a single operator who must stand on the side of the limit to manage the
adjustable stoppers and the pipe securing tray.
Before starting the bending process, the operator shall adjust the limit and secure the material while the
machine is off.

Figure 7. Layout
4.3. Acceptable External Conditions
- A room temperature of +5ºC to +40ºC without exceeding an average temperature of +35ºC over 24 hours.
- Moisture of 30-90% without water condensation.

4.4. Installing the Limit
1. Install the vertical limit support by inserting it into the guides on the end and screw in.
2. Screw in the vertical support using the four screws.
3. Install the guide covers by firmly pressing. Use a plastic hammer if necessary.

4. Unscrew and remove the side shelf of the machine.
5. We lead the end of the inductive wire from the inside to the outside of the machine, through the hole in
the shelf.
ATTENTION: To secure the limit to the machine, you must stop the machine and press the “Emergency
Stop” button.

6. Install the limit on the side of the machine indicated in the image. Remove the 8 screws supplied with
the machine and screw the limit to it using the 8 screws supplied with the limit.
7. We put the shelf back in its place and attach it to the machine by fastening the bolts.

8. Level the machine on the two axles.
9. Level the limit on the two axles.

10. Adjust the height of the vertical support using the two adjustable legs, adjusting the limit to a level posi-
tion.
11. Check that the limit is completely level before definitively securing it to the machine by tightening the 8
screws well.

12. Secure the two securing parts supplied with the limit to the ground.
13. Connect the machine inductive sensor cable by tightening it with the limit inductive sensor.

- 18 -
14. Place the inductive sensor in the limit chassis support and secure it with the bolt. Start the machine
using the power switch.
15. Slide the longitudinal cart until the inductive sensor LEDs turn off. This means it was detected. Make
sure the clamps do not collide with the machine in this cart position.

16. The following message appears on the control screen. Press x so it will disappear.
17. Press to access the menu, then press . Enter the password.
18. Access the E/S menu and activate the backgauge limit switch. Press to return to the home
screen. When the inductive sensor is working, the machine will automatically stop as soon as the
longitudinal cart reaches this limit to prevent the cart from colliding with the machine.

4.5. Adjusting the Limit
The bender switch CC90 is adjusted by our technicians before the machine is sent to the customer. How-
ever, you need to check and re-adjust the limit before working with it.
1. Insert a pipe measuring 1200 mm minimum in the limit as indicated in section 5.2. Securing the Pipe to
the Limit. Use a marker to make a mark at 1000 mm on the other end of the pipe and place it in the main
roller.
2. Place one of the adjustable stoppers at 100 mm and secure it.
