Quick-release couplings
The original hydraulic hoses are fitted with Flat-Face
quick-release couplings that are strong and easy to
clean. The quick-release couplings are fitted so that
the male connection supplies oil and the female
connection receives oil.
NOTICE Wipe all couplings clean before
connecting. Ensure that couplings are clean and
correctly engaged before operation. Failure to do so
may result in damage to the quick couplings and
cause overheating and cause foreign matter to enter
the hydraulic system.
Hydraulic oil
In order to protect the environment, use of
biologically degradable hydraulic oil is
recommended. No other fluids must be used.
♦
Viscosity (preferred) 20-40 cSt.
♦
Viscosity (permitted) 15-100 cSt.
♦
Viscosity index minimum 100.
Standard mineral or synthetic oil can be used. Make
sure to only use clean oil and filling equipment.
When the machine is used continuously, the oil
temperature will stabilise at a level which is called
the working temperature. This will, depending on
the type of work and the cooling capacity of the
hydraulic system, be between 20-40°C (68-104°F)
above the ambient temperature. At working
temperature, the oil viscosity must be within the
preferred limits. The viscosity index indicates the
connection between viscosity and temperature. A
high viscosity is therefore preferred, because the oil
can then be used within a wider temperature range.
The machine must 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 (68°F) and 70°C (158°F).
Pressure adjustment
The maximum pressure of the power source is
important. The pressure created in case of an
incorrectly or unfitted return line coupling would
cause overloading. Which could harm the machine
and result in bodily injuries. The maximum pressure
of the power source is 172 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".
►
Only readjust the pressure relief valve (torque
control) on the machine according to procedure
and values described under maintenance. Note
that higher settings might lead to a higher torque,
which could harm the machine and result in
serious injury or death.
Insertion tool
CAUTION Hot working tool
The tip of the working tool can become hot and
sharp when used. Touching it can lead to burns and
cuts.
►
Never touch a hot or sharp working tool.
► Wait until the working tool has cooled down
before carrying out maintenance work.
WARNING Ejected insertion tool
If the tool retainer on the machine is not in a locked
position, the inserted tool can be ejected with force,
which can cause personal injury.
► Before changing the insertion tool, stop the
machine, switch off the compressed air supply
and bleed the machine by activating the start and
stop device.
Changing auger
Never change the auger or bit when the posthole
borer is connected to a power source.
