succession (Figure C.). To switch it o󰀨, press the query button again.
4.5 Switching on and off
To switch on, press the main switch (Figure M; No� 1)� The device is ready to op-
erate when the main switch and workspace lighting are illuminated blue� To switch
o󰀨, the main switch must be pressed for 0�5-1 second�
4.6 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,Every rescue device has a deadman function� When the star grip is released,

4.6.1 Cutting
Turn the star grip valve in the closing direction� (Figure E�)�
Position the cutter as perpendicular as possible to the object to be cut (Figure F�)�
Cut close to the pivot point of the blade (Figure G�)�
4.6.2 Spreading
Turn the star grip valve in the opening direction (Figure H�)�
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�)�
4.6.3 Pulling
Secure the traction device in the attachment / bolt hole (page 2; gure I; number 6) or
on the spreader tips� Actuate the star grip valve in the closing direction� (Figure E�)�
Note the separate instruction manual for the traction device�
4.6.4 Squeezing
Only squeeze in the squeezing area and with the squeezing plates of the spread-
er arms (Figure K�)� Actuate the star grip valve in the closing direction� (Figure E�)�

4.6.6 Pushing
Place the rescue rams between the object to be pushed and actuate the star grip
valve in the extending direction� (Figure H�)�
4.7 Removing the tips
The removeable tips are connected to the device arm with bolts� To remove the
tips, the bolts must be fully pushed in and then fully locked again (page 2; gure I;
numbers 5+6)
4.8 Automatic switch-off
If the rescue device is not activated for a period of 60 minutes, it switches o󰀨 auto-
matically�
4.9 Dismantling/shutting down after operation
Once work has been completed, the device arms should be closed until the tips are
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�
5. DISPLAY AND CONTROL PANEL
5.1 Main switch (Figure M; No. 1)
For cutting and combination devices, the main switch includes the indicator for the
cutting angle monitoring� (Figure F�)� 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� Attention! Check whether you can complete the cutting process with-
out danger or whether you must reposition on the object to be cut�
5.2 Battery indicator (Figure M; No. 2)
The battery indicator indicates the current battery capacity�
5.3 Load indicator (Figure M; No. 3)
The load indicator scale indicates in what pressure range the tool is while working
and provides information about the remaining capacity�
5.4 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�
5.5 Control light for saltwater battery (Figure M; No. 5)
The control light indicates when a saltwater battery is plugged into the device�

11
en
es
fr
pt
5.6 Warning light for electronics temperature (Figure M; No. 6)
The device independently monitors the temperature of the electronics and emits 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 tem-
perature of less than -10° C, it reduces the speed in order to warm up the battery�
As soon as the battery is warm enough, all functions are available again at normal
speed�
5.7 Illuminated direction indicator (Figure M; No. 7)
Depending on the direction in which the star grip is moved, the device indicates the
motion direction in the display eld.
6. MAINTENANCE AND CARE
6.1 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 o󰀨 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 specications in the spare parts lists.
Any dirt must be removed with a damp cloth� The rescue device should not come
into contact with acids or alkalis� If this is unavoidable, clean the device immediate-
ly afterwards�
An annual inspection of the device is due each year and must be documented�
This annual inspection must be conducted by a person with the necessary exper-
tise� 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�
6.2 Maintenance after underwater use
• Remove the battery after use� Rinse the device and battery several times in
fresh, clean water. Immerse the device completely in order to ll 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 and damp cloth in
order to remove dirt and deposits�
• Leave the device and battery dry at room temperature in a well-ventilated
location� 36-48 hours is recommended� During this drying time, the device is
completely operational�
• Lubricate all exposed steel parts (shear blade, pressure piece, etc�) with anti-
corrosion agent� The contacts in the battery shaft may not be lubricated�
• Perform function test�

6.3 Sharpening the blades
Any burrs may be removed and the blade smoothed only in the grinding area (Pic-
ture)! Break outs or deep cracks cannot be ground away; in such cases the blades
must be replaced�
Tools required:
1� Clamping device (e�g�, vise) with jaw protection
2� Grinder (e�g� angle grinder or belt grinder) with abrasive having a grain size of
80. A diamond le is adequate for small burrs.
Procedure:
1� Clamp the blade securely into the clamping device so that it cannot move,
leaving the grinding area exposed (Picture P�)�
2� Carefully de-burr the grinding area with the grinding machine (Picture P�)�
6.4 Repair
Repairs may only be performed by HURST or personnel trained by HURST�
When doing so, observe the information in the spare parts lists�
6.5 Rechargeable batteries
If the devices are not used for a longer period, we recommend starting up the
device with the appropriate battery 5 times after 30 days� Then charge the battery
completely�
This supports optimal function and availability of the battery and devices�

9. ACCESSORIES
9.1 Batteries
Only HURST lithium-ion rechargeable batteries may be used to operate eDRAULIC
devices� Observe the separate operating instructions for the lithium-ion battery!
A special salt water battery is available from HURST for use in salt and sea water�
9.2 Battery charger
Only the "eDRAULIC Power Pack Charger" may be used for the lithium-ion batter-
ies� Observe the separate operating instructions for the charger�
9.3 Power Supply
For eDRAULIC devices, there is a power supply with which the devices can be
connected directly to a power outlet� The power supply transforms the alternating
current into direct current, so it can be used in place of the battery� Observe the
separate operating instructions for the power supply�
9.4 Chain sets
Chain sets and pulling adapters are required in order to perform pulling operations
with the eDRAULIC spreaders and combination tools (see chapter, “Pulling”)�
Observe the separate operating instructions for the chains sets�
10. INSTRUCTIONS REGARDING DISPOSAL
Please dispose of all packaging materials and removed items correctly� Electrical
equipment, accessories and packaging should always be disposed of in an envi-
ronmentally compatible way�
Only for EU countries:
Do not dispose of electrical equipment with your household waste!
According to the European Directive 2002/96/EC governing electrical and electron-
ic waste and their application in national legislation, old electrical equipment must
be separately collected and recycled in an environmentally compatible manner�
