Accumulator
The accumulator must only be charged with Nitrogen.
NOTICE Only certified personnel are allowed to
work with the accumulator.
EHTMA category
The machine is clearly marked with EHTMA
categories. It is important that any power source used
is in a compatible category. If any doubt, consult an
authorised supervisor.

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
172 bar (2,500 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
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
