Nozzle Tubes and Fittings
Poor sealings are usually caused by:
•
Missing O-rings or gaskets
•
Damaged or incorrectly seated O-rings
•
Dry or deformed O-rings or gaskets
•
Foreign objects
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 it on
to the nozzle tube. Use non-mineral lubricant.
For AXIAL connections, a little mechanical leverage may be used.
For RADIAL connections, only tighten by hand.
Adjustment of 3-Way Valve
The large ball valve (type s93) 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.
μ
ATTENTION! The small ball valves (type s67) cannot be adjusted.
Retighten the Frame
The frame are two sections bolted together. Also the drawbar is bolted to the frame. These bolts need to be tightened
correctly. Check regularly if bolts are tightened according to the specified torques below.
