Proper cleaning is mandatory for long life.
Herbicide equipment requires cleaning much
like spray paint equipment. Many herbicides
will harden in a very short period of time and
cause severe damage. Improper cleaning will
also void the warranty.
The meter should be flushed with water at the
end of each day.
NOTE: Meter reading will change as meter is
flushed.
Remove the pump and meter from herbicide
container. Insert suction pipe into water. Turn
pump on and alternate opening and closing
nozzle until water is free of herbicide residue.
After flushing, let water drain out of suction pipe
and open nozzle to clear most of the water out
of the hose and meter.
NOTE: For best results, disassemble, clean
and inspect annually and replace seals.
Drain herbicide from meter and flush with wa-
ter as described under maintenance.
1. To replace counter and gear assembly,
nutating disc and corresponding seals; re-
move knob (111028-2).
2. Remove 2 screws (904002-13) connecting
the coverplate to the main housing. Then
remove coverplate.
3. Remove 4 screws (904002-12) which hold
counter assembly and then remove this
assembly.
4. Remove 2 screws (904003-37) to remove
the nutator disc assembly (if needed).
5. To reassemble, reverse the above proce-
dure, ensuring that all seals are carefully
in place.
