the safety valve.
(Please note! Observe torque of M
A
= 40 Nm!)
REMARK.
If you want to change the hoses, you have to dismantle the mono-couplings.
CAUTION!
Take care that the port ‘T’ of the rescue tool is always connected to the port ‘T’
of the mono-coupling.

(hexagon socket).
2. Remove handle sleeve A and
washer C. Tighten screwed connection.
If necessary, renew seals.

is no need to carry out this point if the hoses
are just being tightened).
4. Screw the hose with sealing ring back on.
5. Tighten the hose connection on the safety
valve. (Please note! Observe the necessary
torque of M
A
= 40 Nm!) Secure it with
threadlocking uid (e. g. LOCTITE 243).
