DANGER! If one or more the values are exceeded, this may cause damages and sudden leaks on the sprayer. Risk of
injuries and fatal accidents.
Hydraulic Oil
Oil from the tractor to the sprayer must have been filtered according to ISO 4406 20/14 as a minimum. Particles bigger than
25 micron in size must be filtered from the oil (Filtration quotient ß25-75, 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 used for the sprayer hydraulics. Consult the tractor dealer if
in doubt.
