O uiga o le maualuga o le ea DTH hammer e aunoa ma le valve vae.O se ituaiga o maualuga maualuga o le ea i lalo o le pu samala, e aunoa ma le valve vae, O le saoasaoa o le viliina e maualuga atu nai lo le samala ma le valve vae.Ma sili atu le malosi o le malosi.O se tasi o samala DTH sili ona maualuga i le upu .E iai uiga nei:
1.valveless tufatufaina ea, sili atu le faatuatuaina.
2.le piston ei ai se mamanu faigofie, ola umi
3.Long auaunaga ola ma maualalo fua fua faatatau.
4. Fa'aoga faigofie ma faigofie ona fa'aoga.
