Drain Valve Seal Replacement
If the main tank drain valve leaks, the seal and seat can be changed in
the following way.
€
DANGER! Do not enter the inside of the tank - the parts can be
changed from the outside of the tank!
±
WARNING! Use eye / face protection mask, when dismantling the
tank drain valve!
1. Make sure that the tank is empty and clean.
2. The valve must be closed and the string must be loose.
3. Pull out the clip (A) and pull down the connecting piece (B). The
entire valve assembly can now be pulled out.
4. Check cord and valve flap assembly (C) for wear, replace seal (D)
and reassemble.
5. Reassemble the valve using a new valve seat (E). Lubricate O-rings (F) before assembly.
6. Fit clip (A) again.

ATTENTION! Check the valve function using clean water, before filling chemicals into the tank.
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.
Safety Valve Activation
To make the fluid system work perfectly over time, it is good practice to regularly provoke opening of the safety valve.
This prevents clogging and ensures proper function of the safety valve. Opening of the valve is done by turning the pressure
valve to an unused function, when the pump is running. This is good practice for all sprayers; particularly for sprayers without
optional equipment.
€
DANGER! Both the suction valve and pressure valve must always be closed, before opening the Cyclone filter! If they
are not closed, spraying liquid can hit you, when opening the filter and the main tank content will be drained!
