5.13

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.

In the event of confirmation of an oil leak on hydraulic line connections, tighten connections,

and if this does not remedy faults then change line or connection elements. Change of sub-

assemblies is equally required in each instance of mechanical damage.

Because of its composition the oil applied is not classified as a dangerous substance,

however long-term action on the skin or eyes may cause irritation. In the event of contact of

oil with skin wash the place of contact with water and soap. Do NOT apply organic solvents

(petrol, kerosene). Contaminated clothing should be changed to prevent access of oil to skin.

In the event of contact of oil with eye, rinse with large quantity of water and in the event of the

occurrence of irritation consult a doctor. Hydraulic oil in normal conditions is not harmful to

the respiratory tract. A hazard only occurs when oil is strongly atomised (oil vapour), or in the

case of fire during which toxic compounds may be released. Oil fires should be quenched
