Nyob rau hauv cov ntaub ntawv ntawm "gear jump" ntawm kis tau tus mob thaum lub sij hawm tsav tsheb ntawm lub excavator, lub tshuab yuav tsum tau nres nyob rau hauv lub sij hawm, thiab tom qab ntawd qhov ua rau yuav tsum tau pom thiab qhov txhaum yuav raug tshem tawm. Cov txheej txheem tshwj xeeb yog:
(1) Nyob rau hauv cov ntaub ntawv ntawm "gear jump" thaum tsav tsheb ntawm txoj kev tiaj tus, nres lub tsheb raws li lub hauv paus ntsiab lus nres, ua tib zoo xyuas qhov ua rau thiab tshem tawm qhov txhaum.
(2) Yog tias "hla iav" tshwm sim thaum tsav tsheb nce toj, lub iav tuaj yeem teeb tsa rau qhov chaw qis qis lossis iav kuv txoj haujlwm, thiab lub tshuab tuaj yeem nres thaum nws nce mus txog saum txoj kab nqes kom tshem tawm qhov txhaum; Yog hais tias lub downshift tsis ua tiav los yog "gear jump" tshwm sim dua, nres lub tshuab raws li qhov tseem ceeb ntawm qhov kev txiav txim thiab cov kev xav tau ntawm kev kaw ntawm qhov ramp, thiab tshem tawm qhov txhaum.
(3) Nyob rau hauv cov ntaub ntawv ntawm "gear dhia" thaum tsav tsheb nyob rau hauv lub downhill txoj kab nqes, hloov lub iav mus rau lub siab ceev txoj hauj lwm raws li qhov tseem ceeb ntawm cov iav los yog siv "gear rush" (emergency gear down) ntsuas, thiab nres lub tshuab. rau kev tshuaj xyuas thiab kev daws teeb meem tom qab lub tshuab nce mus txog hauv qab ntawm txoj kab nqes; Yog tias "upshift" thiab "upshift" tsis ua tiav, lossis "hla" tshwm sim dua (lub sijhawm no, lub iav tsis muaj zog), tus neeg tsav tsheb tuaj yeem tswj lub cav ceev ntawm qhov nruab nrab ceev, siv txoj kev "snub" kom swb. lub tshuab mus rau hauv qab ntawm txoj kab nqes, thiab ces tshem tawm qhov txhaum. Yog tias "yav dhau los", "gear rush" tsis ua tiav lossis "gear jump" tshwm sim dua (lub sijhawm no, nws yog nruab nrab), thiab lub tshuab yog nyob rau ntawm txoj kab nqes nqes dua, nres nws sai sai raws li qhov tseem ceeb ntawm kev ua haujlwm thiab kev xav tau ntawm downhill shutdown, thiab ces txiav qhov txhaum.
