Oil from the tractor to the sprayer must as minimum
have been filtered according to ISO 4406 20/14. Parti-
cles measured over 25 micron Absolute must be filtered
from the oil (Filtration quotient
β
25-75, ISO 4572-81
Multipass test).
Follow the tractor oil change schedule as directed.
Choose hydraulic oil with anti-foam and anti-oxidant
additives.
Be especially cautious where the tractor transmission oil
is also the oil used for the implement hydraulics. Consult
the tractor dealer if in doubt.

An oil pressure line filter (HARDI ref.
no. 729555) must be installed if the oil
supplied to the sprayer does not fulfill
the minimum oil filtration standard
ISO 4406 20/14.
The HARDI filter has an indicator.
Check that the indicator is green.
If the indicator is red, the filter
element is clogged and needs to
be changed immediately. Ref.
no. for filter element is 284852.

systems. If the tractor is equipped
with closed centre (load sens-
ing) hydraulics e.g. John
Deere, the bypass on the
hydraulic valve block of the
sprayer needs to be
blocked off. The
sprayer is supplied
with an extra
