Safety and operating instructions
of the power source is 160 bar (limited by safety
valve adjustment).
WARNING Operating pressure
If the maximum operating pressure for the hydraulic
machine is exceeded, it can result in material
damage and personal injury.
► Always run the hydraulic machine with the correct
operating pressure. See "Technical data".

Adaptors

Choose a suitable adaptor for the post. To
1)
choose the correct adaptor, see the spare parts
list or accessories catalogue.
Remove the nuts from the bottom plate.
2)
3) Fix the adaptor to the post driver by the
fasteners.
Optional adaptors

Start and stop

Connecting the post driver

Ensure that the hydraulic supply meets the
requirements of the post driver, see "Technical data".
Connect the hydraulic hoses. Make sure the hoses
●
are clean before connecting them. The connectors
are of the 'quick release' type.
The power source must be fitted with a return line
●
oil filter with a filter rating of 10-25µ.
● Back pressure: The back pressure (return line
pressure) of the post driver should be as low as
possible and may not exceed maximum. Back
pressure, see "Technical data", measured at the
post driver in order to avoid functional
disturbances.
● Oil cooler: Oil coolers must be able to stand a
pressure of minimum 10 bar (145 psi) and must
be provided with a by-pass valve opening at a
pressure of 2 bar (29 psi) in case of pulsations in
the return line.
The following is optional settings when connecting
the post driver:
● Oil supply: If the oil supply of the power source
exceeds the flow prescribed, the engine's rpm
must be reduced, until correct oil flow is achieved.
Test equipment can be used, see Spare parts list.
● Oil flow divider: If the oil flow cannot be adjusted
by lowering the rpm, an oil flow divider must be
installed. This will secure the post driver the
correct oil flow and lead excess oil back to the
tank (or to the operating valve block).
Pressure relief valve: To protect the post driver
●
against too high a pressure, the pressure relief
valve of the powerpack must be set in accordance
with the technical data. If that is not possible,
connection can be made by installing a separate
pressure relief valve. In case of doubt, contact
your nearest authorised workshop.
