General repair information

Re-installation:

Every time the ferrule fitting has been loosened, 
retighten the union nut without using increased force.

Ferrule fitting leaks:

If a ferrule fitting leaks, first loosen the union nut until 
some oil escapes and then tighten it as specified.

Progressive ring fittings on hydraulic lines

When pre-assembling the unit and for pre-assembled 
factory-delivered progressive ring fittings, the following 
applies: installation is in the associated, well-oiled 
threaded joint with half a turn of the union nut beyond 
the point where resistance is clearly felt.

Pre-assembly:

1. Cut off the tube at right angles. Do not use a pipe 

cutter because this will slant the tube wall, causing 
heavy inside and outside burrs. Slightly deburr the 
tube end on the inside and outside (do not 
chamfer!) and clean it. In case of tube bends, the 
straight tube end up to where the bending radius 
starts must be at least twice the height of the 
union nut.

2. Push the union nut and the progressive ring on the 

tube.

3. Push the tube against the stop in the union and 

tighten union nut until the progressive ring grips 
the tube (the tube must not rotate with the nut). 
This point can be felt because increase power is 
needed from here.

4. Tighten the union nut half a turn beyond the point 

where resistance is felt.

5. Check the cut made by the progressive ring edge: 

A visible shoulder must fill the space before the 
progressive ring front end. The progressive ring 
may rotate, but axial displacement must not be 
possible.

Installation:

Insert the pre-assembled tube into the well-oiled 
threaded joint, tighten the union nut up to the point 
where resistance is felt and then half a turn beyond 
this point.

Important: Back up the threaded joint with a 
wrench!

Re-installation:

Every time the progressive ring fitting has been 
loosened, retighten the union nut until resistance is felt 
and then continue for half a turn beyond that point.

Important: Back up the threaded joint with a 
wrench!

Progressive ring fitting leaks:

If a progressive ring fitting leaks, first loosen the union 
nut until some oil escapes and then tighten it as 
specified.

Caution!

Failure to observe the tightening torques 
reduces the nominal power and the service 
life of the fitting, resulting in leaks and in the 
tube slipping out.

Taper fittings on hydraulic lines

Montage:

Apply oil to the O-ring on the taper. Tighten the union 
nut a third of a turn beyond the point where resistance 
is felt.

Important: Back up the threaded joint with a 
wrench!

Caution!

Failure to observe the tightening torques 
reduces the nominal power and the service 
life of the fitting, resulting in leaks and in the 
tube slipping out.

Welding

Caution!

When carrying out electric welding work on 
the machine, proceed as follows:

1. Turn off the battery isolating switch!

2. Disconnect the connector to the display monitor.

3. Pull out the electrical plug-in modules in the 

central terminal compartment.

4. Always connect the earth clamp of the welder in 

the near vicinity of the area where the welding is 
being carried out.
