HPP18E
Hydraulic
Powerpack
30 l.p.m. from serial No. 4727
40 l.p.m. from serial No. 4676
Revised 13.04.2011
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 EC noise limits,
but by daily long-lasting operation there is a risk of hearing defects.
2. Always connect hoses before starting.
3. Always keep the electrical box, cables and sockets clean.
4. In case of non-operation or performance of service, always turn off the motor.
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 valve is set at 160 bar from our plant. Never set it 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 HPP18E open centre hydraulic powerpack is designed in accordance with
the EHTMA categories D and E, which prescribe a performance of minimum 30 l.p.m.
or 40 l.p.m. at 138 bar. The HYCON powerpack is fully compatible with and sufficient
for the common European tools.
The powerpack is mounted with a pressure relief valve to avoid a too high pressure.
Furthermore, the very efficient air cooling protects the powerpack against overheating.

Starting Instructions
Please observe the starting instructions on the electric box.
Start: •••• Check hydraulic oil level at sight glass
• Connect hoses and tool
• Press the green button
• If the powerpack does not start, invert the phases in the socket by
means of a screw driver
• Move the lever to “ON”
Stop: •••• Move the lever to “OFF“
• Press the “STOP” button
The powerpack is not equipped with a
phase inverter. If the motor does NOT start,
the phases must be inverted in the socket.
Also see above under “Start”.
Motor Rotation: Counterclockwise (from oil cooler fan side)

Short Circuit
If the motor stops due to a short circuit (water), malfunctioning etc., the fuse in the
relay might need to be reset.
1. Open the electrical box
2. Open the clear doors on the relays (Q34 and Q35)
3. Push the blue fuses to reset the relays (see picture)

Service, Maintenance and Hydraulic Settings
Service/Maintenance Daily Weekly Yearly
Hydraulic oil Check 1 x replacement
Hydraulic oil filter *) 1 x replacement
Check hoses (tighten up if needed)
*) Use only filters with by-pass
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 valve is placed on the valve block on the right side.
1. Connect the test equipment, start the powerpack and move the lever to “ON”.
Then close the valve on the test equipment - the pressure gauge must show 160
bar.
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.
2. When the pressure relief valve has been adjusted correctly, the working pressure
must be set at 100 bar by means of the valve on the test equipment. At 100 bar
check that the oil flow is correct according to the technical data.
Oil Types
The HYCON powerpack uses standard hydraulic oil, i.e. all types of mineral oil and
biodegradable oil, which comply with the following values:
Recommended viscosity
20-
40 cSt
Permitted viscosity
15-
1000 cSt
Viscosity i
ndex
Min.
100
Temperatur
e area
-20°
to +70° C
If correct pressu
re/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.
