Installation

WARNING Whipping hydraulic hose
Hydraulic hoses under pressure can whip
uncontrollably if screws loosen or are loosened. A
whipping hydraulic hose can cause severe injuries.
Depressurise the hydraulic system before
►
loosening the connection of a hydraulic hose.
► Tighten the nuts on the connections of the
hydraulic hoses to the required torque.
Check that the hydraulic hose and the connections
►
are not damaged.

Hoses

For connection on the machine, the hydraulic hose
must be approved for a working pressure of at least
160 bar (2300 psi) and have a 12.7 mm (½ in.) inner
diameter. To resist exterior wear and tear, we
recommend using a 2-layer hydraulic hose. The
machine connection marked P (pump) is the oil inlet,
and the connection marked T (tank) is the oil outlet.
Always connect both hoses and make sure that all
hose connections are tight. Never carry the machine
by the hose.

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
14
cause overheating and cause foreign matter to enter
the hydraulic system.

Hydraulic oil

In order to protect the environment, Atlas Copco
recommends the use of biologically degradable
hydraulic oil. No other fluids must 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 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).

Cutting blades

NOTICE High-quality cutting blades are often most
economical. Lower quality blades often have inferior
cutting capacity and a shorter service life, which
results in a higher cost in relation to the quantity of
material that is cut. The cutting blades must be
approved for free hand cutting machines and rated
for minimum 4400 rpm.
Selecting the right cutting blade
The cut-off saws can be used with both diamond
blades and with the more traditional abrasive discs.
Store and handle the abrasive product with care in
accordance with manufacturer s instructions.
Abrasive discs
Using abrasive discs, the cut-off saw can be used for
cutting steel, concrete, asphalt or other material
depending on the blade type.
