1) Phetisetso ea phetoho ea matla a Oli 4 WG-200 e tlameha ho lumellana ka thata le oli e khothaletsoang ke tafole ea oli e tlotsang ea ZF TEML03 kapa bukana ea litaelo tsa li-loader.
2) Sheba boemo ba oli (hang ka beke)
Paka koloi sebakeng se bataletseng, lebokose la li-gearbox sebakeng se sa nke lehlakore "N" lebokoseng la mocheso o sebetsang, enjene e sa sebetse, e ka bang 1000 RPM / min.
Tlosa dipstick ka tsela e fapaneng le oache 'me ue hlakole
Ha dipstick e kenngoa ka har'a tube ea boemo ba oli 'me e tiisoa, ebe e tlosoa (bonyane ka makhetlo a mabeli) 40C, boemo ba oli bo lokela ho ba pakeng tsa "serame" se tlase le sekala se bohareng.
Ka 80C, boemo ba oli bo lokela ho ba pakeng tsa "chesang" le tekanyo e bohareng
Ho lekola boemo ba oli ea koloi e batang ke feela ho netefatsa hore lebokose la li-gear le converter ea torque li na le phallo e lekaneng ea ho potoloha.Tekanyetso ea ho qetela ea ho fumana boemo ba oli ke ho kopana le boemo ba oli ea koloi e chesang.
3) Kenya sebaka sa oli le mafura a mangata
Phetoho ea pele ea oli e tlameha ho etsoa ka mor'a hore koloi e fihle lihora tse 100 ka lekhetlo la pele.Ka mor'a moo, fetola oli bonyane hang ka lihora tse ling le tse ling tse 1000 kapa selemo le selemo!
Liphetoho tsa oli li tlameha ho etsoa ho latela litlhoko tse latelang:
- Beha koloi sebakeng se bataletseng, lebokose la gear ka mocheso o sebetsang, tlosa polaka ea drain le selikalikoe sa tiiso, tlosa oli ea khale.
Tlhokomeliso: Ha o ntša oli, ha se feela hore oli ea phetisetso e lokela ho tsoa e hloekile, empa le oli ea converter ea torque le radiator e lokela ho tsoa e hloekile.

- Hloekisa plug ea drain le sebaka se koalang sa casing ebe u se kenya hammoho ka reng e ncha e koalang.
- Mafura ho latela ZF e khothalelitsoeng ho tlotsa gauge ea oli.
- Sephethephethe sa taolo ea Gearbox se maemong a sa nke lehlakore "N", qala enjene le ho se sebetse
- Oli ho letšoao le ka holimo la sebaka sa oli se "batang".
- Brake ea ho paka e sebakeng se bolokehileng, likere tsohle li khethiloe khafetsa, lekola boemo ba oli hang, 'me u kenye mafura hape ha ho hlokahala.

Ka 40C, boemo ba oli bo lokela ho ba pakeng tsa "bata" e tlase le tekanyo e bohareng

Ka 80C, boemo ba oli bo lokela ho ba pakeng tsa "chesang" le tekanyo e bohareng

4) Kenya sebaka sa filthara ea oli

Sefahla se setle sa ZF se tlameha ho nkeloa sebaka ke phetoho e 'ngoe le e 'ngoe ea oli.Kenya, tsamaisa le ho boloka lihloela ka hloko!

Lisefe tsa oli tse senyehileng ha lia lumelloa!

Li-filters li tlameha ho kenngoa ka tsela e latelang:

Sebelisa seaparo se tšesaane sa oli ho lesale la ho tiisa.

Tobetsa filthara ho fihlela e ama bokaholimo ba tiiso, ebe u tiisa ka letsoho hoo e ka bang 1/3 ho isa ho 1/2 turn.Ebe u qala enjene ho peterole 'me u hlahlobe boemo ba oli ho latela mokhoa o kaholimo.'Me u hlahlobe hore na filthara e tiile.Sebelisa matsoho a hau ho tiisa hape ha ho hlokahala.
