APPLICATION This procedure is provided to guide all Fresno Fire Department (FFD or Department) members on the safe operation and specifications of Hurst battery powered extrication equipment. This information is to be used during maintenance, training, and emergency operations. OPERATIONAL POLICY Members should operate the tools consistent with the expectations described in the Training and Equipment Manual, Section 306.001, Extrication Equipment Safety Precautions. Members should be familiar with the user interface for the tool and battery prior to operating the tool. OPERATIONAL GUIDELINE If the tool is used underwater, it should be removed from service and a Hurst Certified Technician should inspect and clean the tool as soon as possible. After every use the following should be checked: • Battery pack for damage and function. If damaged, it should be replaced. • The operation of the unit. • Damage or fluid leaks to unit. • Ensure that the Deadman’s (control) handle returns to the neutral position. • Check the entire tool for damage or missing parts.

To switch it off, press the query button again. The flashlight function automatically switches off again after a while. (Figure C) INFORMATION Hurst E Tool Manual Link There are a total of six (6) rechargeable batteries and three (3) chargers. The battery packs not in use should be connected to a battery charger. General Maintenance: A visual check is to be carried out after each use. After every use, the lubrication of the moving parts and bolts must be checked and topped off with a suitable grease, if necessary. The torque of the central bolt on cutting and combination tools must also be checked. To do so, check the specifications in the spare parts lists. Any dirt must be removed with a damp cloth. The rescue device should not contact acids or alkalis. If this is unavoidable, clean the device immediately afterwards. An annual inspection of the device is due each year and must be documented. The annual inspection must be performed by a person with the necessary expertise. A function and load test must be conducted every three years or in case of any safety concerns. Only testing equipment approved by Hurst may be used. Please also observe the relevant domestic and international regulations on the maintenance intervals of rescue devices.

During this drying time, the device is completely operational. • For the rechargeable battery, observe the relevant instructions. • Lubricate all exposed steel parts (shear blade, pressure piece, etc.) with anticorrosion agent. The contacts in the battery shaft may not be lubricated. Repair: Repairs may only be performed by Hurst or personnel trained by Hurst. Contact the shop for service. Batteries: If the devices are not used for a long period, we recommend starting up the device, with the appropriate battery five (5) times after 30 days. Then charge the battery completely. This supports optimal function and availability of the battery and devices. User Interface of the tool: To switch the tool on, press the main switch (Figure M, No. 1). The device is ready to operate when the main switch and workspace lighting are illuminated blue. To switch it off, the main switch must be pressed for three seconds.

(Figure D). 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 retained. (Figure D) Cutting: Turn the star grip valve in the closing direction. (Figure E).

(Figure F) Cut close to the pivot point of the blade (Figure G).

(Figure H) Pulling: Secure the traction device in the attachment/bolt hole (Figure I; No.’s 5, and 6) or on the spreader tips. (Figure I) 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 J).

Actuate the star grip valve in the closing direction. (See Figure E, Page 6). (Figure K) Peeling: Special peeling tips are needed for peeling (Figure L). Actuate the star grip valve in the opening direction. (See Figure H, Page 7). (Figure L) Effective Date: July 2023 Steve McGary, Fire Captain Current Revision Date: 7/11/2023 Section 306.001e Next Revision (2) Date: 7/11/2025 Page 9 of 13 Pushing: Place the rescue rams between the object to be pushed and actuate the star grip valve in the extending direction (See Figure H, Page 7). Lifting: Actuate the star grip in the opening direction (See Figure H, Page 7). When lifting vehicles or other moving loads, make sure that the load is prevented from sliding away and that the spreader tips are placed far enough under the load to prevent slipping. Constantly monitor and support the load when lifting. Automatic Switch-Off: If the rescue device is not activated for a period of 60 minutes, it switches off automatically. Dismantling/Shutting Down After Operation: Once work has been completed, the device arms should be closed until the tip is only a few millimeters apart and the ram piston should be fully retracted and then extended a few millimeters. This relieves hydraulic and mechanical strain on the device. For transport and storage, all devices should be secured and not loosely stored. Display and Control Panel/Main Switch: (Figure M, No. 1) For cutting and combination devices, the main switch includes the indicator for the cutting angle monitoring, (See Figure F, Page 6). If the device twists to the right or left by an angle critical for the blade stability during the cutting process, the blue ring changes color to red. Note: Check whether you can complete the cutting process without danger or whether you must reposition the object to be cut. Battery Indicator: (Figure M, No. 2) The battery indicator indicates the current battery capacity. In Wi-Fi mode, the battery indicator indicates the signal power. Load Indicator: (Figure M, No. 3) The load indicator scale indicates the tool’s pressure range while working and provides information about the remaining capacity. The load indicator also indicates whether the device is sending or receiving data via Wi-Fi.

The turbo function is only available in the low-pressure range. Control Light for Saltwater Battery: (Figure M, No. 5) The control light indicates when a saltwater battery is plugged into the device. Warning Light for Electronics Temperature: (Figure M; No. 6) The device independently monitors the temperature of the electronics and emits and a warning if the temperature reaches a critical range. In case of increased electronics temperature, no more turbo mode is available. Furthermore, the device monitors the battery temperature, and with a cell temperature of less than -10° C, it reduces the speed to warm up the battery. As soon as the battery is warm enough, all functions are available again at normal speed. Illuminated Direction Indicators: (Figure M; No. 7) Depending on the direction in which the star grip is moved, the device indicates the motion direction in the display field.
