Cone check/replacement for EFC distribution valve
Periodically check the distribution valves for proper sealing. Do this by
running the sprayer with clean water and open all distribution valves.
Cautiously remove the clip (A) and pull out the hose (B) for the return
line. When the housing is drained, there should be no liquid flow
through the return line. If there is any leakage, the valve cone (E) must
be changed. Remove the clip (C) and lift the motor housing off the valve
housing. Then unscrew the screw (D) and replace the valve cone (E).
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).
ATTENTION! The wire guide wheels should be directed so they
follow the direction of the wire.
If any deviation is found, do:
1. Pull out the plug (B).
2. Loosen screws (C).
3. Adjust the length of the cord until it reads correctly.
4. Push plug (B) back in place.

NOTE! For best accuracy adjustment shall be done with the
sprayer attached to the tractor normally used.
Level indicator wire replacement
If the wire 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 73) and loosen the fitting holding the pole
in position.
2. Pull the pole down through the drain valve hole till 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!
