WARNING!
To join hoses to each other, to the heaters, or to the gun, hold each hose
end in place with a spanner (1), and with a third spanner tighten or loosen the coupling
nut (2) as required (see Figure 3 18.
These couplers should be tightened to a torque of 20
Nm.
c) Put 18 li
tres of hydraulic oil in the unit’s oil tank. The oil should comply with the
characteristics and specifications of standard DIN 51524 sections 1 and 2 (for example
ISO VG 46).
NOTE:
Do not fill the tank to its maximum capacity (22
litres); the oil level should not exceed 85% of the maximum

Use the visor of the oil
thermometer to check the oil level, as this should always be
completely full (18 litres).
d) Check the oil level in the hydraulic pump by removing
the drain coupler from the pump and making sure the oil
level reaches the top of the filler neck. Add oil if
necessary and reconnect the coupler.
