10.2 Principles on cutting
The blades must be applied at a right
angle to the object to be cut. To enhance
cutting performance, cut as close as
possible to the blade fulcrum. On cutting,
the gap between the blade tips must not
be larger than 3 mm (Risk of blade fracture!).
10.2.1 Attention!
With cutters having curved blades the blade tips must by no means be loaded with full
cutting capacity. Cutting of profi les of up to 2 mm thickness is permissible.
11 Dismantling of the device / Stop after operation
11.1 Cutter unit
After operation, close the blades to a distance of a few mm. This relaxes the unit
hydraulically and mechanically.
11.2 Hydraulic power pack
Stop the hydraulic power pack after operation.
This is mandatory before taking one of the following steps:
11.3 Hoses
Uncouple the red hose fi rst and the blue hose second as described under 8.2. Put dust
caps over the couplings.
12 Maintenance
After each operation inspect the components for perfect function (when the device is
dirty, clean it before inspection):
Visual inspection
Cutter blades
• Cutting edges free from spalling and deformation.
• Distance of blades in transverse direction < 1mm.
• Cutting surfaces slide past each other without contact.
• Blades free from cracks.
• Corrugation of the tips clean and edged without fi ssures.
Cutter unit
• No leakages.
• Easy operation of the star grip.
• Handle existing and fast.
• Check of central bolt tightening torque (see also drawing to Section 13.3.1)

Hoses
• Check according safety instructions for hoses (see item 5).
• Check for oil leakage.
Function testing
• Perfect opening and closing with the star grip valve.
