4. Mosebetsi oa valve ea ho laola ka letsoho
Belofo ea taolo ea tataiso e hokahane le kotola ea shift ka har'a cab.Ho tsamaea ha valve ea spool 'meleng oa valve ho laoloa ka letsoho ho laola phetoho ea oli ea hydraulic.Khatello e kholo ea oli e fanoa ho valve ea taolo ea tataiso, 'me oli ea khatello ea potoloho e kholo ea oli e fanoa ho potoloho ea oli e tsamaellanang tlas'a maemo a fapaneng a ts'ebetso ka ho tsamaea ha valve ea slide.
5. Manual valve interface
Karolo ea taolo ea valve e phahamisang bakeng sa ho tlosa lerōle la mokotla e entsoe ka silinda ea moea, li-electromagnetic reversing valve, poleiti ea valve le molamu oa ho phahamisa.
Ha moeli oa switjha o hlokahala, sesebelisoa sa ho lemoha se ka eketsoa, 'me switch ea makenete holim'a silinda le eona e ka sebelisoa bakeng sa ho lemoha moeli.Belofo e akaretsang ea bypass e na le mokhoa oa ho lemoha maeto.
Taolong ea motlakase, ho sebelisoa mohala o le mong feela oa tšebetso ho laola valve ea solenoid reversing.Palo ea mela e khethoa ho ea ka valve e khethiloeng e khutlisetsang morao.
