2. Product safety

JAWS OF LIFE products are developed and manufactured in order to guarantee the best

performance and quality when used properly.

Operator safety is the most important aspect of the product design.

Moreover, the operating instructions are intended to help the safe use of JAWS OF LIFE

products.

The generally applicable, legal and other binding regulations pertaining to the prevention of

accidents and protection of the environment apply and are to be implemented in addition to

the operating instructions.

The equipment may only be operated by persons with appropriate training in the safety

aspects of such equipment – otherwise, there is a danger of injury occurring.

We would like to point out to all users that they should read the operating instructions

carefully and the instructions contained therein before they use the equipment, and that they

should carefully follow such.

We further recommend that a qualiﬁed trainer train you in the use of the product.

WARNING / CAUTION!

The operating instructions for the hoses, the accessories and the connected

hydraulic equipment must also be observed!

Even if you have already received instructions on how to use the equipment, you should still

read the following safety notes through again.

WARNING / CAUTION!

Ensure that the accessories and connected equipment used are suitable for

the max. operating pressure!

Please ensure that no body

parts or clothing get stuck

between the visibly moving

parts (e.g. spreader arms).

It is prohibited to work under

load if this load is lifted

exclusively by hydraulic

equipment. If this work

is absolutely imperative,

additional mechanical

supports must be used.

Wear protective clothing,

safety helmet with visor,

protective gloves

Inspect the equipment before

and after use for visible

defects or damage

The responsible department

is to be informed immediately

of any changes (including to

the operating behavior)! If

necessary, the equipment is

to be deactivated immediately

and secured!

Inspect all cables, hoses

and screwed connections for

leaks and externally visible

damage! If necessary, repair

immediately! Squirting oil can

result in injuries and ﬁres.

In the event of malfunctions,

immediately deactivate the

equipment and secure it. The

malfunction is to be repaired

immediately.

Do not carry out any changes

(additions or conversions)

to the equipment without

obtaining the prior approval of

HURST.

Observe all safety and danger

notes on the equipment and

in the operating instructions.

All safety and danger notes

on the equipment are to be

kept complete in a legible

condition.

Any mode of operation which

impairs safety and/or stability

of the equipment is forbidden!

Comply with all speciﬁed

dates or dates speciﬁed in

the operating instructions

pertaining to regular controls /

inspections on the equipment.

Safety devices may never be

deactivated! The maximum permitted

operating pressure noted on

the equipment must not be

exceeded.

Before the equipment is

switched on/started up, and

during its operation, it must be

ensured that nobody will be

endangered by the operation

of the equipment.

Only original HURST

accessories and spare parts

may be used for repairs.

Please ensure that, when

working with this equipment

or during transportation of

such, you don’t get caught in

the looped hoses and trip.

When working close to live

components and cables,

suitable measures must

be taken to avoid current

transfers or high-voltage

transfers to the equipment.

Please note that, when

spreading, tearing or breaking

can cause falling material, or

sudden removal of such can

cause it to suddenly catapult

off: necessary precautions

need to be taken.

The build-up of static

charge with the potential

consequence of spark

formation is to be avoided

when handling the equipment.

Only touch any broken-off

parts wearing protective

gloves, since the torn edges

can be very sharp.

The generally applicable, legal and other binding national and international regulations

pertaining to the prevention of accidents and protection of the environment apply and are to

be implemented in addition to the operating instructions.

WARNING / CAUTION!

The equipment is to be used exclusively for the purpose stated in the operating

instructions (see chapter “Intended Use”). Any other or further use is not considered

intended use. The manufacturer / supplier is not liable for any damages resulting from

unintended use. The user bears sole responsibility for such.

Observanceoftheoperatinginstructionsandcompliancewiththeinspectionandmaintenance

conditions are part of the intended use.

Never work when you are overtired or intoxicated!

The equipment is ﬁlled

with a hydraulic ﬂuid.

These hydraulic ﬂuids can

be dangerous to health if

swallowed or their vapors

inhaled. Direct contact with

the skin is to be avoided for

the same reason. Please also

note that hydraulic liquids can

also have a negative effect on

biological systems.

When working with or storing

the equipment, ensure that

the function and the safety

of the equipment are not

impaired by the effects of

stark external temperatures

or that the equipment is

damaged in any way. Please

note that the equipment can

also heat up over a long

period of use.

Ensure adequate lighting

when you are working. Before transporting the

equipment, always ensure

that the accessories are

positioned such that they

cannot cause an accident.

Always keep these operating

instructions within reach

where the equipment is used.

Ensure the proper disposal

of all removed parts, left-over

oil, left-over hydraulic ﬂuid

and packaging materials!

WARNING / CAUTION!

HURST BLUE hydraulic ﬂuid is a custom blended ﬂuid. In case of skin contact,

wash off with soap and water. In case of eye contact, ﬂush with generous

amounts of running water for at least 15 minutes. If discomfort persists following

ﬂushing, see physician for symptomatic treatment.

3. Intended use

HURST spreaders can also be used under water at a depth of up to 40m (131 ft).

CAUTION!

In this case, you must strictly observe any leaks in order to avoid threats to the

environment.

CAUTION!

All objects which are to be worked on are to be secured using stable supports or

substructures.

ﬁg. 1 ﬁg. 2

JAWS OF LIFE spreaders are designed especially for rescue services. They are used to

release persons trapped as a result of a road accident e.g. by forcing open the car doors

(see below ﬁg. 1) or by squashing other parts of the vehicle. In other catastrophic situations

they are used to lift (by spreading) or to displace objects in order to rescue buried or trapped

persons, e.g. by concrete components in collapsed houses (see below ﬁg. 2), and to squash

constructional components, e.g. pipes.

In principle, objects can be pulled, spread, squashed or compressed in length.

All objects to be worked on are to be secured using stable supports or substructures.

When lifting loads, additional risks to the operator and/or persons not involved may be

posed if the load moves in an uncontrolled manner or if the spreader slips or tips over.

When applying the tool and lifting, make sure that there is no danger, if necessary by using

additional supports or safety devices.

WARNING / CAUTION!

The following may not be squeezed:

- live cables

- hardened parts such as springs, spring steels, steering columns

and rollers

- explosive bodies such as SRS systems

NEVER operate the rescue equipment at a higher operating pressure than that

stated in the chapter “Technical data”. A higher setting can result in material

damage and/or injuries.

JAWS OF LIFE rescue spreaders may NOT be used where there is a risk of

explosions!

The rescue equipment should not come into contact with acids or alkalis. If this is

unavoidable, clean the equipment immediately afterwards with a suitable cleaning

agent.

Spare parts and accessories for the rescue tool can be ordered from your authorized

HURST-dealer!

4. Description of the functions

4.1 Description

Theequipmentisdesignedsuchthat,viaahydraulicallyactivatedpiston,twoequal,opposite

spreader arms are symmetrically opened by mechanical joints, thereby spreading objects.

Closing the spreader arms is also carried out hydraulically and mechanically by reverse

order of the piston.

All spreaders ensure full load-holding function when disconnected from the hydraulic supply

(e. g. when being accidentally decoupled; defective hose, etc.).
