Prior to Operation

We thank you for choosing a
HYCON powerpack.

Please note that the power­pack is delivered without hy­draulic oil, and therefore it
must be filled up with hydrau­lic oil prior to operation.

To ensure smooth operation
and long-lasting performance
of your new powerpack, we
recommend that you study
this operating manual carefully
and pay special attention to
the

Safety and Service
Precautions

We hope you will be satisfied
with your new HYCON power­pack.

Best regards

Safety Precautions

1. Always use protective earplugs. The powerpack complies with the EU noise

limit, but by daily long-lasting operation there is a risk of hearing defects.

2. Always connect hoses before starting.

3. Never add fuel and oil when the engine is running.

4. In case of non-operation or performance of service, always turn off the en-

gine.

5. Never start the engine without side covers.

6. Operation of the powerpack without tool connected and with lever at “ON”

may cause overheating of the system and damage to the powerpack.

7. When lifting the powerpack from a vehicle, we recommend the use of a crane.

8. The pressure relief valves are set at 160 bar from our plant. Never set them

higher.

9. Always use filters with by-pass. The use of filters without by-pass may blow

the hydraulic hoses and the filter cover.

Filling Up Hydraulic Oil

 To fill up with hydraulic oil, loosen

the filter cover on top of the power­pack.

 Remove the filter element (see

photo), and fill up with oil. When oil
is showing at the bottom of the filter
unit, there is enough oil on the
powerpack.

 Insert the filter element again, mount

the cover and the powerpack is ready
for use.

Please note: When connecting new extension hoses,
it is necessary to fill up with extra 2 litres of oil.
Therefore always top up the powerpack when
connecting new extension hoses.

Technical Data

Hydraulics

The HYCON HPP18V MULTI FLEX open centre powerpack is designed in accordance
with the EHTMA categories C, D and E, which prescribe a performance of 20, 30 and
40 l.p.m. respectively at 138 bar. The HYCON powerpack is fully compatible with and
sufficient for the common European tools.

The powerpack is mounted with a double pump (two independent hydraulic circuits),
and it has three connections for each circuit separately or both circuits simul­taneously. This way the powerpack can operate two tools simultaneously. For a more
detailed description, please refer to the section about “Setting of Flow”

The powerpack is mounted with pressure relief valves to avoid a too high pressure.
Furthermore, the very efficient air cooling protects the powerpack against
overheating. The powerpack has no POR system, and the engine r.p.m. (oil flow) is
adjusted manually by means of the throttle.

Oil flow connection A 20 l.p.m. at 1800 r.p.m.
30 l.p.m. at 2700 r.p.m.

40 l.p.m. at 3600 r.p.m.

Oil flow connections B and C 10 l.p.m. at 1800 r.p.m.
15 l.p.m. at 2700 r.p.m.

20 l.p.m. at 3600 r.p.m.

Starting Instructions

Please observe the starting instructions on the front of the powerpack.

Start:

 Check engine oil level
 Check hydraulic oil level at sight glass
 Connect hoses and tool
 Switch fuel tap to “ON”
 Activate choke
 Turn ignition key
 Activate electric start or pull recoil starter
 Set the flow – see below

Stop:

 Move all levers to “OFF“
 Turn off the ignition switch
 Turn the fuel tap to “OFF”

Setting of Flow

The powerpack has three connections, allowing for connection of two tools
simultaneously. The connections are marked A, B and C, respectively.

The oil flow can be adjusted by regulating the engine r.p.m. by means of the
throttle. Connection A can be set to 20-40 l.p.m. Connections B and C can be set to
10-20 l.p.m. Connection A cannot be used simultaneously with connections B and C.

Each connection is equipped with an ON-OFF lever. Connections not in use must be
set at OFF, and connections in use must be set at ON. Connections B and C can only
be used when connection A is OFF. Never turn the lever to ON if no tool is
connected.

Hydraulic Settings

Check the working pressure by means of test equipment. The test equipment must
comprise a pressure gauge, a flow meter and a valve for adjustment of pressure.

The pressure relief valves are placed on the valve block. There are two pressure
relief valves (one for each hydraulic circuit), and they must be adjusted individually.
The pressure relief valves are marked with B and C respectively.

1. Connect the test equipment to connection B, start the powerpack and move the

B lever to ON and the A and C levers to OFF. Then close the valve on the test
equipment and adjust the pressure relief valve B according to the technical data.

Adjust the pressure relief valve by loosening the lock nut and turning the
adjustment screw in or out. “In” increases the pressure, and “out” decreases the
pressure.

Retighten the lock nut after adjustment.

Connect the test equipment to connection C, start the powerpack and move lever
C to ON and levers A and B to OFF. Then close the valve on the test equipment
and adjust the pressure relief valve C according to the technical data.

2. Having adjusted the pressure relief valves correctly, set the working pressure to

100 bar by means of the valve on the test equipment. At 100 bar the oil flow
should correspond to the flow rate which the lever is set at (see Setting of Flow).

If correct pressure/oil flow cannot be achieved by following
the above instructions, the powerpack must be re-adjusted.
If the pressure/oil flow is then still incorrect, the pump is
defect and must be replaced.
