WARNING
Hot surfaces
DO NOT operate the post driv er at hydraulic oil
temperatures higher than 60° C (140° F). Higher
temperatures w ill be transmitted to the post
driv er controls and may burn.
WARNING
Accumulator
The

driv er.
Attempting

procedure must be carried out by a qualified
person.
CAUTION
Repairs and maintenance
Do not
try to do
maintenance w ork you do not understand.
WARNING
The hydraulic post driv er is not insulated
against electric current. Should not the post or
post driver come in contact w ith the electrical
pow er sources, there is a risk of personal
inj ury.
WARNING
Modifications and welding
Non-approv ed modifications can cause inj ury
and damage.
CAUTION
Only use lubricants and hydraulic fluids
recommended by the manufacturer.
Safety decals
Decals on the post driver warn you of particular
hazards. Read, and make sure you understand the
safety message, before you work with the post driver.
Keep all decals clean and readable. Replace lost or
damaged decals. The decals on the post driver are as

Connecting/disconnecting the
post driver
Connecting the post driver
1 Ensure that the hydraulic supply meets the
requirements of the post driver (see Specification
the
Section).
the
Note: The A/C range of hydraulic post drivers can be
connected to any supply suitable for this particular
piece of equipment (see Specification Section).
2
Connect the hydraulic hoses. Make sure the
hoses are clean before connecting them. The
connectors are of the `quick release' type. Make
sure they lock in place.
•
Oil supply: If the oil supply of the power
source exceeds the flow prescribed, the engine
r.p.m. must be reduced, until correct oil flow is
achieved (test equipment, order No. 3371801154
can be used).
•
Oil flow divider: If the oil flow cannot be
adjusted by lowering the r.p.m., 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 v alv e: 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 dealer.
•
Back pressure: The back pressure (return
line pressure) of the post driver should be as low as
possible and may not exceed max. Back pressure
(see technical data) measured at the post driver in
order to avoid functional disturbances.
•
Filter: The power source must be fitted with
a return line oil filter with a filter rating of 10-25μ.
•
Oil cooler: Oil coolers must be able to stand
a pressure of min. 10 bar and should be provided
with a by-pass valve opening at a pressure of 2 bar
in case of pulsations in the return line.
