Pronar ZKP800 SECTION 5
5.12
To lubricate intersecting axis gears use gear oil 80W90 GL-4 (SE90 EP) in quantity of 1.1
litre.
If a leak is noticed, carefully inspect seals and check oil level. Transmission operation with
insufficient oil may cause permanent damage of the mechanism.
Repair of transmission during warranty period may only be performed at authorised
mechanical workshops.
5.4 HYDRAULIC SYSTEM OPERATION
DANGER
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 rotary rake 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 rotary rake, the hydraulic system is filled with L-HL32 Lotos hydraulic oil.
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.
