Manual

10
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.
LS 501 EN, LS 530 EN:
On cutting, the gap between the blade tips must
not be larger than 5 mm. (Risk of blade fracture!)
LS 511 EN:
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
