4�5 Actuating The Star Grip Valve; 4�5�1 Cutting; 4�5�2 Spreading; 4�5�3 Pulling - Hurst Jaws Of Life E2 Manual De Operación

4.5 Actuating the star grip valve
The working action is triggered by turning the star grip valve (Figure C)�
Every rescue device has a deadman function� When the star grip is released, Every rescue device has a deadman function� When the star grip is released,
it returns to the center/neutral position automatically� This ensures the load is it returns to the center/neutral position automatically� This ensures the load is
retained� retained�
4.5.1 Cutting
Turn the star grip valve in the cutting direction (Figure D)�
Position the cutter as perpendicular as possible to the object to be cut (Figure E)�
Cut close to the pivot point of the blade� (Figure F)�
4.5.2 Spreading
Turn the star grip valve in the spreading direction (Figure G)�
Open a small gap at the start, then insert the spreader tips as far into the gap as
possible� Do not spread with the aluminum arms! (Figure H�)
4.5.3 Pulling
Secure the traction device in the Attachment / Bolt hole (6)� Actuate the star grip
valve in the closing direction (Figure D)�
4.5.4 Squeezing
Only squeeze in the squeezing area and with the squeezing plates of the spread-
er arms (Figure J)� Actuate the star grip valve in the closing direction (Figure D)�
4.5.5 Peeling
Special peeling tips are needed for peeling (Figure K)� Actuate the star grip valve
in the opening direction (Figure G)�
4.5.6 Pushing
Place the rescue ram between the object to be pushed and actuate the star grip
valve in the extending direction (Figure L)�
4.6 Removing the tips
The removeable tips are connected to the device arm with bolts� To remove the
tips, the bolts must be fully pushed in and then fully locked again (Figure I)�
4.7 Dismantling/shutting down after operation
Once work has been completed, the device arms should be closed until the tips are
only a few millimeters apart and the ram piston should be almost fully retracted and
then extended a few millimeters� This relieves the hydraulic and mechanical strain
on the equipment� For transport and storage, all devices should be secured and not
loosely stored�
