Service schedules
WARNING
Maintenance w ork must only be done by
competent personnel
CAUTION
Only use lubricants and hydraulic fluids
recommended by Atlas Copco.
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.
Badly maintained equipment can be 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)
Viscosity
(permitted)
Viscosity index
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 viscosity 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,

because then the oil can be used within a wider
range of temperatures.
The post driver shall not be used if oil viscosity
fails to remain within the permitted area, or if
the working temperature of the oil does not fall
between +20° C and 70° C.
