Page 9: Proper Use
3. Proper use HURST eDRAULIC devices 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 cutting devices are used to free injured persons at accident scenes by cutting through doors, roof beams and hinges. 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. WARNING / CAUTION / PLEASE NOTE!

Page 11: Functional Description
4. Functional description 4.1 Description The cutting devices 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 blade arms, thus enabling objects to be cut. 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. The light-emitting diodes attached on the operating side light up the work area. The main switch has also been equipped with a ring light, so that you can immediately detect whether the device is switched on or not. When exchanging the battery or power supply, the connection slot will light up for approximately 30 seconds. -

Page 15: Cutting
Note on the operation of the eDRAULIC with a rechargeable battery: If the rechargeable battery remains in the eDRAULIC device with the main switch on, but without activating the star grip, the rechargeable battery will switch itself off after some time (approximately 10 - 60 minutes, depending on the type of battery). If the star grip is then activated, the eDRAULIC device will not switch itself on. In order to resume work with the device, the eDRAULIC device must first be switched off at the mains and then switched on again. Alternatively, the capacity display on the rechargeable battery can be activated or the battery may be briefly unplugged and replugged again. 6. Cutting 6.1 Safety notes Before rescue work can commence, the object must be stabilized in its current position. Ensure that the objects to be worked on are adequately underpinned and/or supported to ensure that there is no risk of sliding or shifting. Worldwide safety guidelines pertaining to the specific country must be observed and complied with. -
Page 16: Cutting
It is strictly prohibited to reach into the path of the rescue device (e.g. between the blade 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 18: Maintenance And Service
8. Maintenance and service The devices are subject to very high mechanical stresses. A visual inspection must therefore be carried out after every use and at least one visual inspection must be carried out every six months. These inspections enable the early detection of wear and tear, which means that punctual replacement of these wearing parts prevents breakage. Regularly check the torque of the pivot bolt on the cutting tools. (You will find the torques for the pivot bolt in the chapter on "Technical Data".) An annual inspection of the tool is due once a year. This inspection must be performed by a person with the necessary expertise. This means that the person must possess adequate specialist knowledge and experience in the fields of electrical engineering and hydraulics, so that they can objectively assess the condition of the tool. Every three years also a crack test of the blades are essential. Therefore a special crack testing kit is is available. 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. -
