6. PERIODIC MAINTENANCE
6.1. LUBRICATION AND MAINTENANCE
After finishing the daily work with the feeder wagon, inspect the
machine, replace all damaged parts (if any), and use the ŁT-43 grease
to lubricate:
•
both grease nipples on the telescopic jointed shaft which couples the
main transmission with the PIC of the machine;
•
points on the telescopic jointed shaft which couples the tractor PTO
with the machine PIC according to the manual supplied with the
shaft;
•
both grease nipples of the PIC bearing mounting on the machine end;
•
both grease nipples of the discharge gate hydraulic cylinder.
These points of the machine are marked with symbol no. 12. Check
the oil level of the main transmission of the vertical mixer drive. Do
this by checking the oil level in the surge tank attached to the mixing
tank on the right side of the machine. The correct oil level is between
the MIN and MAX marks on the surge tank. Use mineral transmission
oils with the viscosity range from 100 to 320 cST at 40°C (quantity:
approx. 15 litres). Change the oil by draining the used oil by unscrewing
the drain valve at the transmission case bottom. Add fresh oil to the
system through the surge tank. Clean the entire machine, repair all
paint coat defects (if any) and remove all corrosion points. Repair or
replace illegible warning and information labels. Protect the hydraulic
lines against direct exposure to sunlight. Store the feeder trailer in a
sheltered location.
6.2. MAINTENANCE AND SERVICING
Regularly inspect the technical condition of the feeder wagon by
checking the guards (on the telescopic jointed shafts), hydraulic lines
and mixer blades. If damage is found, replace the parts with new ones.
If a hydraulic line is damaged, replace it with a new one. Replace all
hydraulic lines every 3 years, starting from the date of its manufacture
stamped on the clamping bush. Before replacing the lines, you must
drain all oil from the feeder trailer hydraulic system. To do it, first turn
off the tractor engine, remove the ignition key and engage the parking
brake of the tractor. Operate each control lever back and forth as during
normal work of the machine. It will reduce oil pressure in the machine
lines to the minimum and drive most of the oil from the feeder trailer
system to the tractor system. Next, open the hydraulic line ends from
the external outputs on the tractor and place the lines in the storage
position. When replacing a line, it is required to wear impermeable
protective clothing and safety gloves suitable for contact with oil-
based products. Before opening a hydraulic line, cover the end to be
opened with a rag impermeable to oil to protect the body and the eyes
from uncontrolled escape of oil from the system. After replacing the
line with a new one, vent the hydraulic system of the feeder trailer. To
do it, couple the feeder wagon's hydraulic terminals with the external
hydraulic outputs on the tractor. Then smoothly operate the level of
the DCV section where the hydraulic line has been replaced, without
starting the hydraulic system. Do this just as if working normally with
the trailer. It will feed the oil from the feeder trailer to the tractor
and eliminate air bubbles from the system. Select the new hydraulic
lines according to the diagram and designations shown in the Parts
Catalogue. The feeder wagon's hydraulic system cannot overheat the
oil due to intermitted operation of each DCV section.
