Page 9: Proper Use
3. Proper use HURST eDRAULIC spreaders have been specially designed to rescue or retrieve the bodies of victims of road, rail or aircraft accidents or to be used during rescue operations from buildings. HURST eDRAULIC spreaders can also be used to free persons who have become trapped by pushing open doors or removing obstacles with the aid of a chain set. During other catastrophic events, spreaders can also be used to move objects to rescue persons who have been buried or trapped. CAUTION / PLEASE NOTE! Care must always be taken that the environment of the object to be processed remains stable and secured against unintentional shifting by using strong supports or underpinning. - Page 10 - prestressed and hardened parts such as springs, spring steels, steering columns and rollers - pipes under gas or liquid pressure, - compound materials (steel/concrete) - explosive bodies such as airbag cartridges The operating pressure placed on the rescue device may only be directly changed after consultation with HURST. A change in settings may result in damage to property and/or injuries. HURST eDRAULIC devices are not explosion-protected! When using the devices in potentially explosive environment, the following must be excluded: - that the device could trigger an explosion.

Page 11: Functional Description
4. Functional description 4.1 Description The spreaders have been designed in such a way that a hydraulically operated piston activates mechanical joints symmetrically to open or close a set of two opposite spreader arms. This movement can be used to spread open, squeeze or pull open objects. For all devices, the movement is activated by means of a valve in the form of a star grip. All devices guarantee the dead man's switch and the full load-supporting function when the star grip is released. HURST eDRAULIC devices do not need to be connected to an external hydraulic source (e.g. a motor pump). Generation of the required hydraulic pressure takes place within the body of the device. Either a battery or an external power supply must be connected as an energy source. You can choose which energy source you wish to use. Both the accumulator battery and the mains power unit can be inserted into the opening provided in the body of the tool. They are then automatically locked into position. You can extend the operating time of your eDRAULIC device by using several batteries. The batteries can be recharged after use, using a suitable external charger. If you are making use of an external power supply, the device can be used for an almost unlimited time. This time is only limited by the external energy source and the overheating switch of the power supply. To allow you to select the best possible energy supply for your eDRAULIC device, neither the battery nor the power supply form part of the delivery scope. You will find suitable bat- teries and power supplies in the HURST accessories list. eDRAULIC devices come with standard light fittings to facilitate work under poor light conditions. -

Operation 5.1 Battery or power supply for eDRAULIC device Commissioning Before initial operation, the battery (where used) of the rescue device must be fully loaded, using the external charger. -
Page 14: Operating The Star Grip
Procedure: 1. Unplug the power supply (where used) from the mains. 2. Fully press down the two unlocking buttons and carefully pull the battery or power supply out of the device. Do not use force! Connection slot 3. The battery can now be recharged in the charger (please take note of the separate operating instructions for the charger and the batteries to be used); alternatively, the power supply can be replaced. 4. Insert the recharged or new battery into the eDRAULIC device until it reaches the stop. The battery or power supply will be automatically locked when correctly oper- ated. 5.2 Operating the star grip (also see chapter on "Operating movement control") Opening the device ( Turn the star grip in a clockwise direction (in the direction of the relevant symbol) and keep in this position. Closing the device ( Turn the star grip in an counterclockwise direction (in the direction of the relevant symbol) and keep in this position. "Dead-man’s" function: Following release, the star grip automatically returns to the central position, fully guaranteeing load retention. -

Worldwide safety guidelines pertaining to the specific country must be observed and complied with. In the Federal Republic of Germany, regular safety inspections according to the regulations of the Gesetzlichen Unfallversicherung (GUV; ‘Legal accident insurance’) are mandatory. WARNING / CAUTION / PLEASE NOTE! HURST eDRAULIC devices are not explosion-protected! When using the devices in potentially explosive environments, the following must be excluded: - that the device could trigger an explosion. - that working with the device could trigger an explosion; e.g. sparks may result from cutting an object. -
Page 16: Spreading
It is strictly prohibited to reach into the path of the rescue device (e.g. between the spreader arms and the material/object to which the force is to be applied)! CAUTION / PLEASE NOTE! The strong effect of the force of the rescue equipment during operation could cause pieces of the vehicle to break off or fly off, posing a danger to persons. -

Page 20: Dismantling The Equipment / Deactivation Following Operation
WARNING / CAUTION! With particularly hard materials, chips may break out in an uncontrolled manner. Please maintain the safety distance! 7. Dismantling the equipment / deactivation following operation Once work has been completed, the device arms should be closed until the tips are only a few millimeters apart. This relieves the hydraulic and mechanical strain on the equipment. NOTE: Never store the eDRAULIC devices with fully closed arms! By fully closing the arms hydraulic and mechanical tension may develop in the device. Clean the rescue device after each operation and grease both the metallic and the mechanically movable parts. The lock of the spreader plug-on tips should also be greased from time to time. Greasing provides protection against excessive wear and tear or corrosion. Avoid storing the rescue equipment in a damp environment. -
Page 21: Maintenance And Service
Federal Republic of Germany, regular safety inspections according to the regulations of the Gesetzlichen Unfallversicherung (GUV; ‘Legal accident insurance’) are mandatory. ATTENTION! Clean off any dirt before checking the equipment! WARNING / CAUTION / PLEASE NOTE! To perform maintenance and repairs, personal safety equipment appropriate for the work is a mandatory requirement. The maintenance and repair staff must have adequate technical and specialized knowledge. HURST offers appropriate training courses for this. 8.1 Oil change Under normal working conditions routine oil changes are not necessary with eDRAULIC tools. The prerequisite is that: • the tools are always properly handled and stowed as per the applicable operating manual • the tools are tested on a regular basis as per our instructions on preventive maintenance • after 10 years service life an oil change is recommended Regular tests, oil change and/or repairs must be carried out by repair and maintenance personnel that is trained and authorized by the manufacturer. -
