DANGER
Do not repair hydraulic system on your own. All hydraulic system repairs must be
performed only by suitably qualified personnel.

Before commencing whatever work on hydraulic system reduce the pressure in the
system.
DANGER
During work on hydraulic systems use the appropriate personal protection equipment
i.e. protective clothing, footwear, gloves and eye protection. Avoid contact of skin with
oil.
Always adhere to the principle that the oil in the mower hydraulic system and in the tractor
hydraulic system are of the same type. Application of different types of oil is not permitted. In
a new mower, the hydraulic system is filled with HL32 hydraulic oil.
ATTENTION!
The condition of hydraulic system should be inspected regularly while using the
machine.
The hydraulic system should be completely tight sealed. Inspect the seals when hydraulic
ram cylinders are completely extended. In the event of confirmation of oil on hydraulic ram
cylinder bodies ascertain origin of leak. Minimum leaks are permissible with symptoms of
"sweating", however in the event of noticing leaks in the form of "droplets" stop using the
machine until faults are remedied.
