(1) Isisabalalisi ngesikhathi sokusebenzisa, njengokuthi ukuvela kwesikulufa akuguquki noma akukho endaweni, kufanele sihlole inathi yokulungisa, bese sihlola izingxenye ezilandelayo:

① Uma isiphethu esishubile se-pawl sonakalisiwe, uma sonakalisiwe, kufanele sishintshwe;

② Uma umshini wokudlulisela uminyene, njengokubhajwa, ugcotshwe kabi, khona-ke uwoyela wokugcoba (noma ugrisi) kufanele wengezwe ekuxhumekeni okususwayo kwendlela yokudlulisela. Uma iphinikhodi liqine kakhulu, kufanele lifanele amantongomane axegayo. Uma uxhumano lukhululekile, ithubhu yokudlulisela noma enye i-deformation bar, kufanele ilungiswe;

③ i-buffer spring stretch incane kakhulu, uma incane kakhulu, kufanele ufinyeze ubude boxhumano lwe-buffer spring lwentambo.

(2) ukusetshenziswa kwe-spreader kufanele kube ukuvimbela imiyalelo ekupendeni kwepuleti lenkomba. Uma usutholakele, udinga ukugcwalisa ngokushesha izimpawu zokuqala zikapende.

(3) Okwentambo ku-spreader, kufanele ihlanzwe ngesikhathi futhi igcotshwe ngamafutha okugcoba noma amafutha, ikakhulukazi ukugoba kwentambo yocingo.

(4) Ezingxenyeni eziyinhloko zamandla, amaringi, ama-spin locks, ama-ear panel namaketango ekhebula, ekusetshenzisweni okuvamile kokukhipha imvume, okungenani njalo ngemva kwezinyanga ezi-3 ukuhlola kanye, akukho mifantu nokuwohloka okukhulu.

(5) Zonke izinkomishi zikawoyela, okuhlanganisa izinkomishi zikawoyela zemishini ye-ratchet, izinkomishi zikawoyela ezindlini zokushelela nezinkomishi zikawoyela zamabhokisi okukhiya ajikelezayo, kufanele zigcwaliswe ngamafutha okugcoba ngokuvumelana nemibandela yokusetshenziswa.

(6) ngokuvamile hlola ikhadi intambo kuyinto okuxekethile, isiphethu buffer kuyinto ukwelula ngokweqile, wathola ukuthi inkinga ngesikhathi.

(7) Isabalalisi ngasinye angeke seqe isisindo esilinganiselwe, isiphethu sebhafa akumele sinwebe ngokweqile.

(8) inqubo yokuphakamisa kufanele kube ukuphakamisa okushelelayo, ukugwema isisakazeli kanye nama-cranes noma ezinye izinto zokusebenza, njengomthelela wokunye kanye nokuguqulwa.
