Guide values for mains connection

The power cable must be dimensioned by a qualified person in accordance with national and local regulations. The mains socket
to which the machine is connected must be dimensioned for the same amperage as the machine's electrical socket and extension
cable, e.g. a 63 A electrical socket must be preceded by a 63 A fuse.

*The cable lenght is calculated with respect to a voltage drop of 20 V during operation. Type of power source and wiring from power
source to power outlet affects possible cable length.

The hydraulic system pressure

Type of pressure
Pump pressure
The pressure in the pipes between pump and main stop
valve. The pressure varies between standby pressure and
max. pressure depending on which hydraulic functions are
being used.
Standby pressure*
* The pressure that the pump delivers when no function is activated and the circulation valve is shut.
Hydraulic fluid and lubricant
Hydraulic fluid
Quality
Mineral oil ISO VG32
ISO VG46 (Standard) mineral oil.
Mineral oil ISO VG68
Always ask the machine manufacturer before using a type of hydraulic fluid other than those mentioned above.
The type of hydraulic oil delivered with the machine is stated on the decal at the inside of the left top cover.
NOTICE! The machine can be damaged if different types of hydraulic fluid are mixed. Check which quality of hydraulic fluid the
hydraulic system contains before refilling or changing.
