WARNING! Leaking or popped-out threaded plugs!
If a threaded plug which is of a different measurement system, kind of seal and size
with respect to the female thread is pressurized, the threaded plug may loosen itself
or even be ejected from the hole in a projectile-like manner. This can result in serious
injury and damage to equipment. Hydraulic fluid can be discharged from this leakage
point.
▶ Use the drawings (installation drawing) to determine the required threaded plug
for each fitting.
▶ Make certain that there are no mix-ups when installing fittings, mounting bolts
and threaded plugs.
▶ For all female threads, use a threaded plug from the same system of units and of
the correct size.
