WARNING
Hot surfaces
DO NOT operate the ground rod driver at
hydraulic oil temperatures higher than 60° C
(140° F).
Higher
transmitted to the ground rod driver controls
and may burn.
WARNING
Accumulator
The ground rod driver incorporates a pressure
accumulator. This accumulator is pressurized
even when there is no hydraulic pressure to the
ground rod driver. Attempting to dismantle the
accumulator
without
pressure can cause injury or death. This
procedure must be carried out by a qualified
person.
CAUTION
Repairs and maintenance
Do not try to do repairs or any other
maintenance work you do not understand.
WARNING
The
hydraulic
ground
insulated against electric current. Should the
rod or ground rod driver come in contact with
the electrical power sources, there is a risk of
personal injury.
WARNING
Modifications and welding
Non-approved modifications can cause injury
and damage.
CAUTION
Only use lubricants and hydraulic fluids
recommended by the manufacturer.
Safety decals
Decals on the ground rod driver warn you of particular
hazards. Read, and make sure you understand the
safety message, before you work with the ground rod
driver. Keep all decals clean and readable. Replace lost
or damaged decals. The decals on the ground rod
driver are as shown.

Connecting the ground rod driver
1
Ensure that the hydraulic supply meets the
requirements of the ground rod driver (see
Specification Section) and it is stopped.
the
Note: The A/C range of hydraulic ground rod 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 and not damaged 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).
not
•
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 ground rod
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
ground rod 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 ground rod driver should be as
low as possible and may not exceed max. Back
pressure (see technical data) measured at the
ground rod 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.
