To enable comprehension of the function, a simplifi ed hydraulic cylinder of the rescue
equipment (A) + hand valve (B) are depicted here.
The spreading arms movement is controlled via the star grip on the mounted valve.
A HURST motor pump or hand pump only may be used to drive the equipment.
If the pump unit is a different make, you must make sure that it complies with HURST
specifi cations, otherwise potential dangers may occur which are not the responsibility of
HURST.
Ensure in particular that the authorized operating pressure for HURST equipment is not
exceeded.
REMARK:
Before you use pumps from a different manufacturer, you must contact HURST
or an authorized dealer.
The pump unit and the rescue tool are connected by hoses.
