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).
NOTICE
The setting of the pressure relief valve on
the machine can in some cases be higher than the
prescribed maximum setting according to the
EHTMA category, see "EHTMA category". A too high
pressure relief valve setting can harm the machine
to be used. Readjust the pressure relief valve, if the
technical specifications of the machine prescribe a
lower pressure relief valve setting than the standard
setting of the machine.
Hydraulic control and
connectors
C
H
G
The by-pass valve (C) must be in the OFF position
when starting and in the ON position when using
the machine.
Connectors (G) and (H) are used to connect the
power pack to the machine as follows:
♦
Connector (G) = Return (female quick-release
coupling).
♦
Connector (H) = Feed (male quick-release
coupling).
Hoses and connections
Ensure that the machine you plan to use is
compatible with the model of power pack being
used. Otherwise, both the power pack and the
machine might be harmed. Check the "Technical
data" in this instruction book and compare the flow
rate with the technical specifications in the
instruction book for the machine.
Connecting hoses
♦
Turn the by-pass valve to the OFF position and
stop the engine/motor.
♦
Make sure the couplings are clean and serviceable.
♦
Attach the return line hose and the feed line hose.
♦
Start the engine/motor and run the power pack
to fill up the hydraulic circuit. Check the hydraulic
oil level.
Disconnecting hoses
♦
Turn the by-pass valve to the OFF position and
stop the engine/motor.
♦
Remove the feed line hose and the return line
hose.
The couplings are unlocked by moving the collar
back on the coupling.
Hose length
For power packs giving a flow of 20 l.p.m. (5 US
gal/min), a maximum hose length of 21 m (69 ft) is
recommended. For power packs giving a higher
flow, a maximum hose length of 14 m (46 ft) is
recommended.
Normally, 7 m (23 ft) of Twin hose is used for the
power pack.
Twin hoses and other accessories are shown in the
spare parts list.
