Insait long konstraksen masin indastri, ol 'excavator' em ol bikpela ikwipmen, na wok na gutpela bilong ol i save mekim wok i go het na wok gut. Tasol, olsem wanpela bikpela samting bilong mekim ol ikwipmen i wok gut, planti taim ol i no save tingim ol 'excavator filter'. Tru tumas, ol filta i no inap long bagarapim pawa na fuel ekonomi bilong masin bilong digim graun tasol, tasol ol i bikpela samting tu long mekim ol ikwipmen i stap longpela taim na daunim ol kos bilong lukautim.
Ol filta bilong 'excavator' i gat ol 'hydraulic oil filter', 'fuel filter', na 'air filter', na olgeta wan wan i save mekim wok bilong ol yet long lukautim gut wok bilong ol ikwipmen. Dispela 'air filter' i save 'filterim' win i go insait long ensin, na i save pasim das na ol pipia long go insait long 'combustion chamber', na dispela i save pasim ensin long bagarap na bagarapim wok bilong ensin. Sapos 'air filter' i no wok gut dispela inap long mekim win i no inap go insait na paia i no inap kukim gut, na dispela inap long mekim pawa i go daun na yusim planti bensin. Dispela 'fuel filter' i save mekim 'fuel' i stap klin, na i no inap long pasim ol 'injectors' o bagarapim 'fuel pump', na i save mekim ensin i wok gut. Dispela 'hydraulic oil filter' i save lukautim 'hydraulic system' long ol samting nogut, na i save lukautim klinpela 'hydraulic oil' na i save mekim ol 'hydraulic components' i wok gut. Sapos yu no senisim ol filta oltaim o yusim ol filta we i no gutpela tumas dispela inap long mekim ol ikwipmen i bagarap planti taim. Olsem, sapos yu no senisim 'air filter' inap longpela taim dispela inap long mekim ensin silinda i bagarap hariap na sotim laip bilong ikwipmen. Sapos 'fuel filter' i pas, dispela inap long mekim ensin i stop o stat wantaim hevi. Kontaminesen bilong 'hydraulic oil' inap long daunim wok bilong 'hydraulic system' na tu inap long bagarapim ol masin. Olsem na, makim ol gutpela filta na bihainim gut ol mentenens saikel em ol bikpela samting bilong mekim gutpela wok bilong masin bilong digim graun.
Long sotpela tok, maski i luk olsem ol i no bikpela samting, ol 'excavator filter' em ol samting we yumi no inap lukim long ai bilong lukautim ol gutpela wok bilong ol ikwipmen. Sapos yumi lukluk gut long wok bilong lukautim na senisim ol filta, yumi inap long mekim ol 'excavator' i wok gut longpela taim, daunim ol kos bilong wok, na mekim wok bilong projek i kamap gutpela moa. Ol wokman bilong indastri i mas kliagut long bikpela wok bilong ol filta na putim ol insait long menesmen bilong ol bikpela ikwipmen.
