Ha piston e fihla tlase, valve e koala ho thibela motsoako hore o se ke oa sutumelloa ka ntle, o phahamisa piston. Hamorao, ka mor'a ho hlahloba kabo, re tla bona hore mona, hape, re tla ema hanyane pele re koala valve ...

Khatello

Kaha joale silinda e tletse, ntho e 'ngoe le e' ngoe e koetsoe 'me piston e phahama, kahoo e hatella motsoako. O e sutumelletsa kerese, e lutseng ka bohlale ka phaposing e tukang. Ho fokotseha ha molumo oa motsoako le ho eketseha ha khatello ho tla phahamisa mocheso, o tla thusa ho chesa. Nakoana pele piston e fihla holimo (sebaka se phahameng sa ho se nke lehlakore, kapa PMH), spark plug e tuka pele ho nako ho qala ho tuka.
