Note:
Before working on the motor pump or for coupling/decoupling the hoses, make sure that the motor
pump is switched off (electric connection) or disconnected from the mains and that the lines are
unpressurized.
9.2 Operating of the star grip 1
Opening of the arms:
Rotate star shape ring 1 to the right hand side and hold it in this position.
Closing of the arms:
Rotate star shape ring 1 to the left hand side and hold it in this position.
Load sustain function:
If released, the star shape ring 1 returns automatically to center position, maintaining fully the load
sustain function.
10 Cutting, Spreading and Pulling
10.1 Safety advise
Before the rescue operation begins, the object to be worked upon must be stabilized.
In each country, the country-specific safety regulations must be regarded.
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 spreader, 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
(LKS10: 2mm).
(Risk of blade fracture!)
10.3 Spreading
Use the tips only for widening the gap. When approximately half of the grooved area is used, the
full spreading power may be applied. Maximum force is exerted in the rear section of the tip.
