SECTION 306.001e HURST BATTERY POWERED EXTRICATION EQUIPMENT
PURPOSE
To provide standard practices for the safe operation of Hurst battery powered
extrication equipment.
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.

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.

Maintenance After Underwater Use:
• Remove the battery after use.
• Rinse the device and battery several times in fresh, clean water.
• Immerse the device completely to fill the housing with clean water.
• Lift the device out and let it drain completely.
• Depending on the type of water (mud, sludge, algae, salt water, etc.) in which
the device was used, repeat these steps another 2-5 times.
• Wipe the device and the battery with a clean, dust-free, damp cloth to remove
any dirt and deposits.
• Perform function test.
• Leave the device to dry at room temperature in a well-ventilated location, 36 to
48 hours is recommended. 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 M, No. 1)
Actuating the Star Grip Valve:
The working action is triggered by turning the star grip valve. (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 E)
Position the cutter as perpendicular as possible to the object to be cut (Figure F).

Spreading:
Turn the star grip valve in the opening direction (Figure H).
(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).

(Figure J)
Squeezing:
Only squeeze in the squeezing area with the squeezing plates of the spreader arms
(Figure K). 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).

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.

Control Light for the Turbo Function: (Figure M, No. 4)
The star grip can be moved by 20° in any direction; with a move starting at 15°, the
turbo function is activated, the device moves faster. 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.
