The long service life and efficiency of a machine depends to a large extent on regular
lubrication. Use mineral greases for lubrication. Clean the lubrication points thoroughly
before pressing or applying grease.
CAUTION! It is forbidden to work on a damaged machine caused by any
event resulting in a broken, or deformed frame, roller or other assembly
of the machine!
5. Technical maintenance
•
After completing the work, lubricate roller bearings, hinges and cylinder bolts
(at
least every 10 hours of operation)
.
For lubrication purposes, the grease of type
ŁT
-
43 can be used.
•
Once the work is completed, the soil residues must be removed from the roller.
Check the connections and subassemblies. Tighten any loose screw connections.
Replace or refurbish any damaged or worn parts.
•
Use only original screws and nuts when replacing worn parts.
•
Always remember to tighten the bolt connections properly.
•
Replace or refurbish any damaged or worn parts.
•
Before a new work season is commenced, always add up the grease in the bearing
assemblies.
CAUTION! During any maintenance work, the roller must rest on the ground.
The tractor engine must be stopped.
5.1.
Hydraulic system maintenance (knife roller H)
Maintenance of the hydraulic system (Fig. 12) involves visual inspections for its leak
tightness. Remember to insert pins into quick
-
fit connectors. In case of oil leakage from
connections of hydraulic hoses, the connector must be tightened. If the oil leakage is not
remedied, replace the element or the hose with a new one. If the leakage occurs outside
the connector, replace the leaking hose with a new one. Mechanical damage also requires
replacement of the subassembly. It is recommended that the hydraulic hoses be replaced
every 5 years. If oil appears on the piston rod of the hydraulic cylinder, check for the
nature of the leakage. Check the sealing once the piston rod is fully moved out. Minor
leakage which results in covering the piston rod with an oil film is acceptable. If the
amount of oil is greater or there are oil drops, shut down the unit for the period required
to repair the malfunction (defective wiper seal).
