WARNING - keep hands away from the blade: danger of being cut. - check the position of the knife respect to the bottom knife in order to avoid any collision.
1) PNEUMATICOPERATION Knob A with 3 positions1.1 Red position → REST: air flow stop.1.2 Yellow position → SET-UP: knife blade descent and set-up approach.1.3 Green position → RUN: knife blade descent and run approach.
2) OVERLAPADJUSTMENT(at1stinstallationonly) Knob B: 2.1 Verify that the number shown in the window above knob B is identical to the blade knife Ø being actually used (usually 150 mm) otherwise turn the knob up to show the actual value.2.2 Turn the knob A to the yellow position (SET-UP) in order to check the overlap of the knife in respect to the bottom knife.2.3 Turn the knob A back to the red position.2.4 Unscrew and remove the grub screw from the knob B. Take care not to lose this screw.2.5 Turn the knob B counter clockwise/clockwise in order to increase/decrease the blade overlap.2.6 Repeat the step sequence 2.2, - 2.3 - 2.5 - 2.2 to obtain the blade overlap requested (usually 0.5÷1.5 mm).2.7 Screw the grub screw on knob B.
3) CANTANGLEADJUSTMENT Knob C:3.1 Turn the knob A to red position.3.2 Loosen the set screw in the center of the knob C.3.3 Rotate the knob C counter clockwise or clockwise, depending on the material direction and blade cartridge position, to adjust cant angle to desired value. Each notch corresponds to 0.25°. Attention: The cant angle must be adjusted by turning the knob clockwise. Every time you turn counter clockwise the knob you must: - turn the knob counter clockwise of (at least) one more notch than desired value - then turn the knob clockwise to desired value.3.4 Tighten the set screw of knob C. Attention: Do not loosen the radial set screws on knob C to maintain the shop calibration.
4) BEFOREPERFORMINGTHECUT4.1 Move and lock the bottom knife to the required slitting position.4.2 Turn the knob A to the yellow position (SET-UP) then move the knifeholder so that knife touches the bottom knife.4.3 Lock the knife holder on its rail.4.4 Turn the knob A back to the red position.

WARNING Before performing the maintenance operations: - put on safety gloves. - turn the knob A on red position.
5) TOREMOVETHEBLADECARTRIDGE 5.1 Pull the lever D up.5.2 Grab the handle F and, holding down the safety latch pin E, slide the blade cartridge off.
6) TOINSERTTHEBLADECARTRIDGE6.1 With lever D up, slide the blade cartridge onto the knife holder until the safety latch pin E snaps in place, indicating the correct position.6.2 Pull the lever D down to lock the blade cartridge.
7) TOREPLACETHEBLADE7.1 Remove the blade cartridge as shown in 5).7.2 Loosen the grub screw H of lock-nut L.7.3 Keep the blade lock pin I pressed and turn the lock-nut L until it is locked.7.4 Unscrew the lock-nut L using the compass key or by hand. Release the lock pin I.7.5 Remove blade from the ring-nut. To mount the blade follow the inverse procedure paying attention not to tighten the grub screw H too much.
8) AFTERBLADEREGRINDINGORREPLACEMENT In order to maintain constant the blade overlap after the knife blade regrinding or replacement:8.1 Measure the outside diameter (in mm) of the knife blade before mounting it. 8.2 After mounting the knife, turn the knob B until you can view the value of the measured diameter in the window above the knob. Note: the adjustment step of the knob B is 0.5 mm.

9) TOREVERSETHEBLADECARTRIDGE In this way a left-hand knifeholder can become a right-hand one (and vice versa):9.1 Remove the blade cartridge as shown in 5).9.2 Turn the blade cartridge 180° and insert it as shown in 6).9.3 Repeat the procedures 2), 3), 4) if necessary.
10) TOREMOVETHECOMPLETEKNIFEGUARD10.1 Unscrew and remove the screws G on the knife guard (two on one side and two on the opposite side)10.2 Slide the knife guard off.
