The engines of type Briggs & Stratton have a main switch, which must be actuated for
switching the aggregate on and off. The accelerator cable of these engines does not have to
be readjusted and is fixed in the position „ “. Nevertheless, if it is necessary in exceptional
cases to switch the engine into idle running, the accelerator lever can be lifted over the
adjusting plate and be switched into the position „ “.
5.3 Valve variants
5.2.2 Gasoline / petrol
These hydraulic units are equipped with a combustion engine driven by the fuel "gasoline /
petrol".
(For specific details, please consult the separate operating instructions of the engine
manufacturer!)
In all cases, the valves are designed as connecting blocks. This block is firmly integrated into
the hydraulic unit. Both hoses (pressure and return) are always connected to the connecting
block. There are various connection blocks with different valve variants available for the
different requirements of operators and the various areas of application.
REMARK:
For certain regions, the selection of the control valves is limited due to applicable
standards and legal regulations.
Bear in mind that only the variants that are officially approved for your region will
be deployed!
CAUTION!
When operating several pieces of rescue equipment with one unit, ensure that
the usable volume of hydraulic fluid in the reservoir is greater than the maximum
possible operating fluid volume of all connected rescue equipment.
5.3.1 Control valve "single operation"
This variant only enables the connection of one pressure hose and one return hose. Turning
a lever / switch controls the pressure application to the pressure hose, i.e. the pressure on
the pressure hose is switched on or off.
5.3.2 Control valve "alternative operation"
This valve enables the connection of two pressure hoses and two return hoses. Turning a
lever / switch controls the pressure application to the pressure hoses. However, only one
device can be provided with pressure at any one time.
As a general principle, there are two different connection blocks for each connection block
variant. A block is conceived for screwing in mono-couplings directly and for screwing on
hoses. On the mono-coupling variants, an adapter can be used to screw on hoses directly.
On the hose connection variant, the built-in connection nipples can be replaced by quick-
disconnect coupling halves.
It goes without saying that LUKAS can also provide adapter sets to connect mono-couplings
to a hose connection block. These adapter sets consist of a supply and return hose with a
mono-coupling fitted on one end.
5.2.4 Diesel
These hydraulic units are equipped with a combustion engine driven by the fuel "diesel".

manufacturer!)
