When working in an environment which involves a risk of explosions, do not use motor/engine
powered pumps. Instead, use hand pumps.
When operating rescue devices, wear
- protective clothing
- helmet with visor or goggles
- protective gloves.
During operation of the cutter, parts of the object worked on may break away and endanger people
standing nearby. Onlookers must be kept at a safety clearance of at least 5m.
Do not get your hands in between the blade arms.
Do not cut
- live wires
- pressurized gas or fluid lines
- prestressed and hardened parts (such as springs, spring steels, steering columns, rolls)
- composite materials (steel/concrete).
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!)
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 first and the blue hose second as described under 8.2. Put dust caps over
the couplings.
12 Maintenance
After each operation a visual check has to be accomplished, at least once per annum. Every 3
years or if there are doubts about security or reliability, an additional funtional test has to be
accomplished.
(clean them first if necessary)
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
