In case of leaks:
DO NOT overtighten. Disassemble, check condition and position of
O-ring or gasket. Clean, lubricate and reassemble.
The O-ring must be lubricated ALL THE WAY ROUND before fitting
on to the nozzle tube. Use non-mineral lubricant.
For AXIAL connections, a little mechanical leverage may be used.
For RADIAL connections only hand-tighten them.
Nozzle tubes and fittings
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
The MANIFOLD valve can be adjusted if it is too tight to operate - or
if it is too loose (=liquid leakage). Correct setting is when the valve
can be operated smoothly by one hand. Use a suitable tool and
adjust the toothed ring inside the valve as shown on the drawing.
