In all LUKAS hydraulic units, a motor typically operates a hydraulic pump, which delivers
uid from the tank and builds the pressure. The distribution of the uid is then controlled by
integrated valves.
5.2 Motor
These hydraulic units are equipped with a 4-cycle combustion engine, which is operated with
petrol. (refer to chapter "Fuel")
5.3 Control valve
ATTENTION!
In the operation of multiple rescue devices with a unit, make sure that the usable
amount of hydraulic uid in the uid tank is greater than the maximum possible
amount of operating uid of all connected rescue devices together!
The installed valve makes it possible to supply two devices simultaneously with pressure.
The pressure supply of both hydraulic connections, and consequently the pressure supply of
the connected rescue devices, can be controlled by way of the two control switches.
5.4 Pumps
LUKAS SUPER SILENT units are equipped with a dual ow pump.
Dual ow pump 2 pump delivery ows
The pumps used are always equipped with two pressure circuits per pump delivery ow,
a low-pressure and a high-pressure circuit.
Low-pressure circuit (ND) = up to 14 MPa*
High-pressure circuit (HD) = up to 70 MPa*
The switch from low pressure to high pressure is automatic in the pump.
The maximum pressure is limited by a pressure control valve.
WARNING / CAUTION / ATTENTION!
For safety reasons, the pressure set at this valve must not be changed (without
the direct consent of LUKAS)!
*(1 MPa = 10 bar)
5.5 Connection to rescue devices
The connection to the rescue devices is created by extension hose pairs or hose reels. They
are offered in different lengths, anti-kink colours and different connection options.
The standard hose pairs from the LUKAS line of accessories are always equipped with
monocouplings on at least one end in order to connect them to LUKAS rescue devices. The
individual hose lines of a hose pair can be differentiated by the different colours in order to
avoid confusion of the pressure and return lines.
(For more details, please refer to the LUKAS line of accessories or contact your LUKAS
dealer.)
9
5.6 Connection options
The connections for the hydraulic hoses are always provided on the unit.
The unit is provided exclusively with monocouplings.
6. Connection of the hose lines
ATTENTION!
When connecting the hose lines, make sure that the connection components are
not dirty and if necessary clean immediately beforehand!
ATTENTION!
Only devices in the basic position may be connected to the unit in order to avoid
that an amount of hydraulic uid greater than the maximum ll quantity can enter
the tank of the unit!
WARNING / CAUTION / ATTENTION!
Before connecting devices, make sure that all components
used are suitable for the maximum operating pressure of the
hydraulic unit! In case of doubts, LUKAS must be consulted
directly before connecting the devices!
The hydraulic hoses are connected via quick-disconnect coupling halves (female and male)
to the hydraulic pump in such a way that they cannot be reversed.
Dust caps
Male coupling
Before coupling, remove dust caps, then connect male and female couplings and turn
locking sleeve of the female coupling in direction "1" until the locking sleeve engages. The
connection is then made and secured. The decoupling is accomplished by turning the locking
sleeve in direction "0".
The coupling of the devices under pressure is also possible, assuming the connected
equipment is not turned on.
10
Female coupling
NOTE:
We recommend, when ambient temperatures are low and extension hoses /
hose reels are used, connecting the coupling halves in a depressurised state
because decoupling may otherwise require a very large exertion of force.
For dust protection, the supplied dust caps must be reattached.
WARNING / CAUTION / ATTENTION!
The monocouplings must not be unscrewed and/or the hose lines reversed!
7. Installation and commissioning
7.1 Installation
WARNING / CAUTION / ATTENTION!
Due to the possibility of spark formation, combustion engine units must not be
used in areas at risk for explosion.
No units containing combustion engines may be used in closed rooms due to
risk of poisoning and/or suffocation!
The unit should be installed at a suitable site (secure location / at surface / suf cient distance
from vehicles, loads, ignition sources, etc.).
In order to ensure maximum safety and uid withdrawal quantities, you should operate the
unit in a horizontal position to the extent possible.
7.2 Commissioning
For commissioning, you should proceed in the following way:
1. First, check the uid levels of the unit. To do so, the unit must sit horizontally on a stable
and at surface and the motor must be switched off.
Procedure for motor oil level:
a) Remove the oil ller cap and check the oil level of
the motor (see gure on right).
b) If the oil level is below the lowest level, suitable
oil (refer to chapter "Motor oil recommendations")
must be replenished to the upper mark. When
checking the oil level, do not turn the oil ller cap.
c) Change the oil when the oil is dirty. (refer to chapter
"Repairs")

Procedure for fuel level:
WARNING / CAUTION / ATTENTION!
Never add fuel while you are smoking or in the vicinity of naked ames!
a) When the tank is empty, ll it with unleaded
petrol.
b) The fuel level should never exceed the upper edge
on the fuel strainer. (see gure below)
c) It is essential that the fuel strainer is used on the
ller neck. (see gure on right)
d) When using the unit for the rst time, or when
stopping due to a lack of fuel, after replenishing
fuel pull the reversing starter handle several times
up to the upper edge of the fuel strainer of the
fuel tank.

WARNING / CAUTION / ATTENTION!
To prevent re, read all warnings!
• Do not replenish the tank with the motor running or a hot motor!
• Before adding fuel, turn the motor switch to the 0 position (" ") = STOP!
• Ensure that no dust, dirt, water or other foreign matter can enter the fuel!
• Keep away from naked flames!
12
Procedure for hydraulic uid level:
a) Open the uid ller cap and check the hydraulic
uid level by looking into the ller pipe (see gure
below). If the bottom of the ller pipe is just barely
still covered with hydraulic uid, the unit is at the
lowest permissible hydraulic uid level. If the
hydraulic uid is almost in the angled part of the
ller pipe, the maximum permissible ll level has
been reached.
WARNING / CAUTION / ATTENTION!
If more uid is added than up to the
maximum permissible level, there is
a risk that the uid can leak. If the
hydraulic uid also drips onto hot
motor components, the re hazard is
extreme!
b) If the hydraulic uid level is below the lowest level,
suitable hydraulic uid (see chapter "Hydraulic
uid recommendations") must be replenished to
the maximum ll level.

2. Before starting the motor, perform the following checks:
• Are there leaks in the fuel line?
• Are all screws and nuts tightened?
• Do individual components have damage or breakages?
• Are there leaks on the hydraulic lines and screw connections?
3. Thereafter, the hydraulic unit should be bled.
Procedure for hydraulic uid level:
a) Set all valve switches to "0".
b) Set the motor switch to "0".
c) Slowly crank the motor with the starter rope several times.
This procedure allows slow intake of the pump and good bleeding. The hydraulic uid
tank is equipped with automatic bleeding so that no additional venting measures are
required.
4. Check the hydraulic uid level in the tank again. If necessary, you should add uid to the
ll level.
13
5. The unit is now operational. To use it, place it on a suitable, level site!
WARNING / CAUTION / ATTENTION!
Observe the following:
• Remove easily ammable or other hazardous material from the surroundings
of the unit!
• Install the unit at least 1 m (39.4 in.) away from walls or other structures!
• Operate the unit only in a dry, well-ventilated area!
• Ensure than no foreign objects can enter the exhaust pipe!
• Do not bring naked flames in the vicinity of the unit! Do not smoke!
• Install the unit on a flat, stable surface!
• Do not block any air ducts of the unit with paper or other material!
6. Finally, you can connect the extension hoses and/or hose reels (as described in the
chapter "Connection of the hose lines").
8. Operation

3. Set the motor switch to position " " (STOP).
WARNING / CAUTION!
Never touch the hot motor parts; it could cause severe burns.
16
8.3 Controlling the valves
Two switches are provided on the valve. Each switch is assigned to the pressure connection
beneath it. By ipping the respective switch, the pressurisation of the corresponding pressure
line can be controlled.
There are 2 control stages for each switch:
0 = Depressurised circulation (no pressure supply of the hydraulic line)
0 = Pressure supply of the pressure line
8.4 Opening the side parts
In order to gain access to the following parts for maintenance and repair work, take off the
corresponding side cover by removing the screw with a screwdriver or a coin.
Left side cover: air lter, fuel cock, etc.
Right side cover: oil level gauge, ignition coil, spark plug, hydraulic uid
lling, etc.
9. Removal of the device / Shutdown after operation
After the work is completed and before shutting down the unit, you should bring all connected
rescue devices into the basic position (storage position). Then you can stop the motor of the
unit.
Couplings:
If the connected hose lines are supposed to be removed during shutdown, decouple the
monocouplings as described in the chapter "Connection of the hose lines". Ensure that you
place the dust caps again on the monocouplings.
Clean the hydraulic unit before storing it to remove dirt caused by the use.
With a longer storage time, the outside of the device should be cleaned and the mechanical
moving metal parts need to be oiled. You should also drain the fuel from the tank.
Avoid storing the hydraulic units in a damp environment.
17
Additional measures on the motor for longer storage periods:
If the unit will not be used for a period of 6 months or more, the following measures
must be taken:
• Loosen the fuel line and carefully drain the
tank.
The quality of petrol remaining in the tank
deteriorates, and starting the motor becomes
more dif cult.
• Use a hand pump to drain the fuel from the
tank and insert it in the lling port.
• Loosen the drain plug on the carburettor.
• Replace the motor oil.
• Check to ensure that no screws and nuts have
become loose, if necessary retighten them.
• Pull the handle of the recoil starter until you
feel resistance and leave the handle in its
position.

10. Care and maintenance
The hydraulic units are subject to very high mechanical stresses. Therefore, a visual inspection
needs to be made after each use, but at least once every half-year.
In this way, early signs of wear are recognizable so that damage to the device can be avoided by
prompt replacement of these wear parts. Also check regularly to make sure that all attachment
screws are tightened (heed any applicable tightening torque speci cations).
Every 3 years, or if there is a doubt about the safety or reliability, a functional check should
be also performed (For this purpose, also heed the corresponding applicable national and
international speci cations related to the maintenance intervals of rescue devices). In the
Federal Republic of Germany, regular safety technology tests are prescribed in accordance
with the regulations of the Statutory Accident Insurance (GUV).
ATTENTION!
Clean the device before checking for dirt!
WARNING / CAUTION / ATTENTION!
To perform maintenance and repairs, personal safety equipment appropriate for
the work is an absolute requirement. (incl. shields).
