Lo matshini usetyenziselwa ukugcwalisa ulwelo olwahlukeneyo, ulwelo lwe-viscous okanye iimveliso zolwelo ezityebileyo, njengeoyile yokupheka, ioyile yolube, isiselo, ijusi, isosi, intlama, ikhrimu, ubusi, ishampu, isicoci, isibulali zinambuzane, kunye nesichumiso solwelo njl.njl. ukuhamba. Yamkela ukugcwaliswa kwempompo yepiston nge-servo motor eqhutywa ichaneke ngakumbi kwaye kulula ukuyilungisa umthamo. Ngevalve ejikelezayo yeemveliso zolwelo ezityebileyo okanye ezine-viscous kunye nevalve engeyiyo ejikelezayo yeemveliso zolwelo.
Inokudityaniswa nabanye oomatshini be-autmoatic ukuqamba umgca wokuzalisa ngokuzenzekelayo kunye nokupakisha, njenge:
