Even if you have already received instruction on how to use the equipment, you should still
read through the following safety instructions again.
CAUTION!
Ensure that the accessories and connected equipment are suitable for the
maximum operating pressure!
Please ensure that no body
parts or clothing get stuck
between the visibly moving
parts.
Immediately report any changes
that occur (including changes
in operating behaviour) to
the appropriate persons/
departments! If necessary, the
equipment is to be shut down
immediately and secured!
Wear protective clothing, safety
helmet with visor, safety shoes
and protective gloves.
Check the equipment for visible
Àaws or damage before and
after use.
Working under suspended
loads is not permitted where
such loads are being lifted only
by means of hydraulic devices.
If this work is unavoidable,
suitable mechanical supports
are also required.
Check all lines, hoses and
screwed connections for leaks
and externally visible damage,
and repair immediately!
Escaping hydraulic Àuid can
cause injuries and ¿res.
7
In the event of malfunctions,
immediately deactivate the
device and secure it. Repair the
fault immediately.
Do not carry out any changes
(additions or conversions) to the
equipment without obtaining the
approval of HURST beforehand.
Observe all safety and danger
information on the device and in
the operating instructions.
All safety and danger
information on the device must
always be complete and in a
legible condition.
Please ensure that all safety
covers are present on the
equipment and that they are in
proper and adequate condition.
Any mode of operation which
compromises the safety and/
or stability of the device is
forbidden!
Safety devices must never be
disabled! The maximum operating
pressure set on the equipment
must not be changed!
Make sure before switching
on/starting up the device and
during its operation, that this will
put no one in danger.
Observe all intervals for
recurring tests and/or
inspections that are prescribed
or stated in the operating
instructions.
When working close to live
components and cables,
suitable measures must be
taken to avoid current transfers
or high-voltage transfers to the
equipment.
Only original HURST
accessories and spare parts are
to be used for repairs.
When working with this
equipment or when transporting
it, ensure that you do not get
caught up in the hose or cable
loops and trip.
The build-up of static charge
and therefore possible sparking
must be avoided when handling
the device.
Do not touch the engine and
exhaust system when running
with combustion engine pumps
because of the danger of
burning.
Motorised pumps must not be
operated in areas at risk of
explosion!
Combustion engines must not
be operated in enclosed spaces
because of the danger of
poisoning and / or smothering.
8
Keep combustion engines and
their fuels away from sources
of ignition since otherwise there
will be a danger of explosion.
All damaged electrical
components e.g. scorched
cables, etc. are to be replaced
immediately!
In order to prevent the danger
of ¿re, you should ensure
adequate ventilation when
operating combustion engines
and you must keep a safety
distance of at least 1m (39.4 in.)
to walls and other screens.
Damage to electrical
components must only
be repaired by a quali¿ed
electrician in compliance with
all applicable national and
international safety guidelines
and regulations.
Make sure that the combustion
engines are always standing on
as Àat and horizontal a surface
as possible to prevent fuel from
leaking out.
When setting up the units, you
must make sure that they are
not impaired by the inÀuences
of extreme temperatures.
The equipment is ¿lled with
hydraulic Àuid. This hydraulic
Àuid can be detrimental to
health if it is swallowed or its
vapour is inhaled. Direct contact
with the skin must be avoided
for the same reason. Also,
when handling hydraulic Àuid,
note that it can negatively affect
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 severe
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.
Make sure there is adequate
lighting while working. Before transporting the
equipment, always ensure that
the accessories are positioned
in such a way that they cannot
cause an accident.
Always keep these operating
instructions easily accessible at
the place of operation.
Ensure the proper disposal of
all removed parts, leftover oil,
hydraulic Àuid and packaging
materials.
If you spill any fuel when using
combustion engines, you
must remove the spilled fuel
completely before starting the
engine.
Refuelling whilst the engine is
running is strictly prohibited!

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 device is intended exclusively for the purpose stated in the operating instructions
(see chapter "Proper Use"). Any other use is not in accordance with its designated
use. The manufacturer/supplier is not liable for any damages resulting from improper use.
The user bears sole responsibility for such use.
Proper use includes observance of the operating instructions and compliance with the
inspection and maintenance conditions.
Never work in a fatigued or intoxicated state!
WARNING/CAUTION!
If you still injure yourself on the hydraulic unit, clean the wound immediately and
consult a doctor to have it attended to!
If you get hydraulic Àuid in your eye, rinse it immediately several times with clear,
clean water and consult a doctor!
Also, if you swallow hydraulic Àuid you should consult a doctor!

3. Proper use
You can obtain accessories and replacement parts for the rescue apparatus from your
authorised HURST dealer!
WARNING/CAUTION!
The safety instructions in this operating instruction manual concerning the site of
erection and type of erection must always be observed!
HURST hydraulic units are specially designed to supply HURST rescue equipment with
hydraulic Àuid so that this equipment can be used to rescue victims of road, rail or air traf¿c
accidents as well as from buildings.
Their use for supplying pressure / Àuid to rescue equipment of other manufacturers is
possible, yet requires the technical inspection and approval by HURST in each individual
case.
ATTENTION!
When selecting the units to connect to the unit, bear in mind that the maximum
possible useable volume of hydraulic Àuid is limited.
The sum of the max. required operating volume (hydraulic Àuid) of all connected
equipment must not exceed the maximum possible usable volume of the power
unit!
NOTE:
Always register your hydraulic unit on the HURST Jaws of Life internet site. This
is the only way to guarantee your extended warranty cover.
Before you use couplings from a different company, you must contact HURST
or an authorised dealer.
HURST ML-630 units are not explosion protected!
When using the equipment in explosion-risk areas you must make sure that
operation of the unit does not trigger an explosion!
The responsibility for explosion prevention or for ruling out work with the ML-630
rests with the operator of the device or with the person responsible at the place
of use.
When working in areas at risk of explosion, all applicable legal,
national and international regulations, standards and safety rules
for avoiding explosions must be observed without limitation!
The equipment should not come into contact with acids or alkalis. If this is
unavoidable, clean the equipment immediately afterwards with a suitable cleaning
agent.
CAUTION!
The ML-630 power units were not developed for being operated without hoses
or devices (operating time < 15 minutes).
