Hydraulic couplings, pipes and hoses
Hydraulic pipes must always be loosened at both
ends when dismantling.
It is essential to use two tools, of which one is used
as a counterhold, both when loosening and
tightening hoses, so that the hose is not exerted to
tensional stress or rotation when tightening. Elbow
nipples can fail or cracks occur when loosening or
tightening without counterhold.
When assembling hydraulic lines, rst tighten until
the tapers make contact, i.e. as far as can be
tightened easily. Then tighten a further one and a
half ats. Any further tightening should be avoided.

Always check and note how hose, lines, pipes, etc.
are tightened throughout the machine before
loosening or dismantling. They must always be
retted with the same tightening force as originally.
Always check when assembling hoses and lines,
that they go clear of locations where they can be
exerted to chang and wear.
Always check after retting hoses, lines, pipes, etc.,
that there is no leakage.
