the hydraulic system.

Hydraulic oil

In order to protect the environment, Atlas Copco
recommends the use of biologically degradable
hydraulic oil. No other fluids should be used.
♦ Viscosity (preferred) 20-40 cSt.
♦ Viscosity (permitted) 15-100 cSt.
♦ Viscosity index Min. 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 lie 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 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 (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 160 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.

Water flushing

For diamond bit core drilling, water flushing is
required. Mount the water swivel and water hose on
the core drill as follows.
The water can be supplied directly from a source, or
a separate water kit can be used. A separate water
kit with pressure tank is available, see the spare parts
list.

Drill bit

Choosing drill bit

A correct drill bit is a condition for good operation.
To avoid unnecessary machine damage, it is
important to choose drill bits with a high quality.

Fitting and removing the drill bit

Smaller diameter drill bits are fitted directly into the
machine drive shaft (½" BSP). For larger diameter
drill bits, use an ½" BSP male x 1¼ UNC male drive
adaptor, which is included with the machine.
To prevent an accidental start:
1) Switch off the power supply and disconnect
the machine from the power source.
Screw the drill bit into the machine.
2)
Lock the spindle using a spanner and tighten
3)
the drill bit.
4) Bleed the machine by pressing the start and
stop device.
