Screw-type safety couplings (Pioneer)
• To tighten the couplings (A), make sure that
the system is depressurized. Push the cou-
plings completely together to full engage-
ment, and tighten the locking ring of the fe-
male coupling to the male coupling. If the
couplings are not fully tightened, the tool will
not operate.
• To loosen the couplings (B), make sure that
the system is depressurized. Loosen the
locking ring of the female coupling from the
male coupling and pull the couplings apart.
Toothed screw-type safety couplings (HYTORC
716)
The coupling is identical to the screw-type safe-
ty couplings (type Pioneer), but both coupling
are toothed. The male coupling has a toothed
locking ring which is axially displaceable. The
female coupling also has a toothed ring.
• To tighten the couplings (A), make sure that
the system is depressurized. Push the cou-
plings together and engage the teeth of male
coupling and the female coupling. If the cou-
plings are not fully tightened, the tool will not
operate.
• To loosen the couplings (B), make sure that
the system is depressurized. Pulll the tooth-
ed locking ring axially and loosen the locking
ring.
Quick couplings (HYTORC 1008)
• To tighten the couplings (A), make sure that
the system is depressurized. Pull back the
pull-back ring on the female coupling, push
the male coupling into the female coupling
and release the pull-back ring. Screw the
locking ring on the female coupling against
the pull-back ring.
• To loosen the couplings (B), make sure that
the system is depressurized. Screw the lock-
ing ring on the female coupling from the pull-
back ring. Pull back the pull-back ring to re-
move the male coupling from the female
coupling.

Warning:
• Make sure that the system is depressurized.
