Matoorku wuxuu u baahan yahay inuu nuugo hawo badan inta lagu jiro habka shaqada. Haddii hawada aan la sifeynin, boodhka hawada ku xayiran ayaa lagu nuugi doonaa dhululubada, taas oo soo dedejin doonta xirashada kooxda piston iyo dhululubada. Qaybaha waaweyn ee ka soo gala bistoonka iyo dhululubada waxay sababi karaan "jiiditaanka dhululubada", taas oo si gaar ah halis ugu ah goobaha shaqada ee engegan iyo ciidda leh. Shaandheeyaha hawada waxaa lagu rakibay kaarburetarka hortiisa ama tuubada qaadashada si looga sifeeyo boodhka iyo ciidda hawada, iyadoo la hubinayo in hawo ku filan oo nadiif ah ay gasho dhululubada.
Marka loo eego mabda'a sifeynta, filtarrada hawada waxaa loo qaybin karaa nooca shaandhada, nooca centrifugal, nooca qubeyska saliidda iyo nooca isku dhafan.
Inta lagu jiro dayactirka, xubinta shaandhada warqadda waa in aan lagu nadiifin saliid, haddii kale xubinta shaandhada warqaddu way fashilmi doontaa, wayna fududahay in ay keento shil xawli ah. Inta lagu jiro dayactirka, kaliya habka gariirka, habka saarista burushka jilicsan (si aad u cadaydo laalaabkii) ama habka dib u soo celinta hawada ee ciriiriga ah ayaa kaliya loo isticmaali karaa si looga saaro boodhka iyo wasakhda ku xiran dusha shaandhada warqadda. Qaybta shaandhada aan fiicneyn, boodhka ku jira qaybta ururinta boodhka, daabadaha iyo tuubada duufaantu waa in la tirtiraa wakhtiga. Xitaa haddii si taxadar leh loo ilaalin karo mar kasta, xubinta shaandhada warqaddu si buuxda uma soo celin karto waxqabadkeedii asalka ahaa, caabbinta hawaduna way kordhi doontaa. Sidaa darteed, guud ahaan, marka element filter warqad u baahan yahay in la sii hayo markii afraad, waa in lagu beddelo element cusub filter. Haddii xubinta shaandhada warqaddu dillaacdo, daloolto, ama warqadda shaandhada iyo koofiyadda dhammaadka la googooyo, waa in isla markiiba la beddelaa.
