Poor seals are usually caused by:
- missing O-rings or gaskets
- damaged or incorrectly seated O-rings
- dry or deformed O-rings or gaskets
- foreign bodies
In case of leaks:
DO NOT overtighten
. Disas-
semble, check condition and
position of O-ring or gasket.
Clean, lubricate and reassem-
ble.
The O-ring must be lubricated
ALL THE WAY ROUND
before
fitting on to the nozzle tube. Use non-mineral lubricant.
For
RADIAL
connections only hand-tighten them.
For
AXIAL
connections, a little mechanical leverage may
be used.
