Safety and operating instructions
The label indicates the guaranteed noise level
corresponding to EC-directive 2000/14/EC. See
"Technical data" for accurate noise level.
Accumulator
The accumulator must only be charged with
Nitrogen.
NOTICE
Only certified personnel are allowed to
work with the accumulator.
EHTMA
The European Hydraulic Tool Manufacturers
Association (EHTMA) has categorised hydraulic
power packs and tools in terms of flow rate and
working pressure. See section "Technical data".
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.

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).
