Cone check/replacement for pressure regulation valve (EVC)
If it becomes difficult to build up sufficient pressure or if pressure
fluctuations occur, it may be necessary to replace cone and cylinder.
1. Remove 4 x screws (A) and remove the housing.
2. Remove 4 x screws (B).
3. Replace cylinder (C) and O-ring (D).
4. Loosen the nut (E), remove and replace the cone (F).
5. Reassemble in reverse order.
Level Indicator Adjustment
The level indicator reading should be checked regularly. When the tank
is empty, the float should lie on the stop pin (D) of the rod, and the O-
ring on the indicator should be positioned at the top position line (A).
If any deviation is found, do the following:
1. Pull out the plug (B).
2. Loosen screws (C).
3. Adjust the length of the cord, until it reads correctly.
4. Push the plug (B) back into place.

NOTE! To obtain the best accuracy, the adjustment should be
done with the sprayer attached to the tractor normally used.
Level Indicator Cord Replacement
If the cord on the level indicator has to be changed, the float guide pole is removed.
1. Remove the tank drain valve (see “Drain valve seal replacement” on page 94) and loosen the fitting holding the pole
in position.
2. Pull the pole down through the drain valve hole, until it is free in the top of the tank.
3. The pole can now be taken out of the tank through the filling hole.

DANGER! Do not enter the inside of the tank - the parts can be changed from the outside of the tank!
