Connecting/disconnecting the
post driver
Connecting the post driver
1 Ensure that the hydraulic supply meets the
requirements of the post driver (see Specification
Section).
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 . m u st be red u ced, until co rre ct oil flo w i s
achieved (test equipment, order No. 3371801154
canbeused).
• Oil flow divider: If the oil flow cannot be
adjusted by lowering the r.p.m., an oil flow divider
m u st b e i n stall ed . T hi s wi ll se c u re th e p o st d ri ve r 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
acco rd ance wi th the te chni cal data. If that i s 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 cool ers m ust be abl e to stand
a pressure of min. 10 bar and should be provided
wi th a by-pa ss val ve ope ni ng at a pressure o f 2 bar
in case of pulsations in the return line.
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 post driver incorporates a pressure
accumulator. This accumulator is pressurized
ev en when there is no hydraulic pressure to the
post driv er. Attempting to dismantle the
accumulator without first releasing the
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 h ydraulic post driv er is not insulated
against electric current. Should not the post or
post driver come in contact with the electrical
pow er sources, there is a risk of personal
injury.
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.

T (tank) is the exit point.
Quick release couplings
In the original, hydraulic hoses are fitted with
Flat-Face quick release couplings.
This kind of quick release coupling is stronger and
easier to clean. The quick release couplings are
fitted so that the male connection supplies the oil and
the female connection receives the oil.
Quick release couplings shall be approved for a
minimum 140 bar working pressure.

.
6. Activate the trigger. When the LPD is within reach,
grasp the handles.
7 When driving, make sure you are able to keep safely
balanced. Keep arms and legs clear of the post, if a
post breaks during operation the post driver with a
projecting broken shank will suddenly drop.
8 Avoid activating the post driver when it is
re m oved from the po st a nd g rou nd. T hi s wil l le ad to
increased hydraulic oil temperatures and seal wear.
9 DO NOT invert the post driver without first isolating
the hydraulic supply.
11 Do not continue to work if the hoses vibrate
abnormally.
12 Do not “ride” the machine, e.g. with one leg slung
over the handle. This could result in injury, especially if
the tool were to break.
13 Investigate the contents of the material in which you
are going to work. Look out forhidden cables and
pipes, e.g. electricity, telephone, water, gas, or sewage
lines.
14 If you suspect that the post has struck a hidden
object, stop the machine immediately. Make sure there
is no danger before continuing with the work.
15 Only use the machine for the jobs for which it is
i ntend ed.
Be alert
Always concentrate on what you are doing. Use
common sense. Never operate the machine when you
are tired or under the influence of drugs, alcohol or
other substances which might affect your vision,
reaction ability or judgments.

Service schedules
To make sure your post driver keeps working to
maximum efficiency, it is essential that it is
properly and regularly maintained in accordance
with the service schedules included in this
handbook.
Ba dl y m aintain ed equi pment can b e a danger to
the operator and the people working around him.
Make sure that the regular routine maintenance
and lubrication jobs listed in the service
schedules are done to keep the equipment in a
safe and efficient working condition.
Do not use equipment which is due for a service.
Make sure that any defects found during the
regular routine maintenance checks are rectified
before you use the equipment.
Scrapping w orn-out machines
Worn-out machines should be scrapped so that
as much material as possible is recovered and to
cause as little environmental impact as possible.
NB. Before a worn-out hydraulic post driver is
scrapped it must be emptied and cleaned of all
hydraulic oil. Waste hydraulic oil shall be handled
in such as way as to cause no environmental
impact.
Recommended hydraulic oil
In order to protect the environment Atlas Copco
recommends the use of biologically degradable
hydraulic oil.
Viscosity
(preferred) 20 – 4 0 cSt
Viscosity
(permitt ed) 15 – 1 00 c St
Viscosit y ind ex M in. 10 0
Standard mineral or synthetic oil can be used.
When the post driver is used continuously the oil
temperature will stabilize at a level which is
called the working temperature. This will be,
depending on the type of work and the cooling
capacity of the hydraulic system, between 20 -
40°C above the ambient temperature.
At working temperature oil vi scosi ty must lie
within the preferred limits. The viscosity index
indicates the connection between viscosity and
temperature. This is the reason why a high
viscosity is preferred,
becausethentheoilcanbeusedwithinawider
range of temperatures.
The post driver shall not be used if oil viscosity
fa il s to remain wi thi n the pe rmi tted area, o r i f
the working temperature of the oil does not fall
between +20°C and 70°C.
