1. Fampidirana
This manual provides essential information for the safe and effective operation, maintenance, and troubleshooting of your HiKOKI DH28PCY Rotary Hammer. Please read this manual thoroughly before using the tool to ensure proper handling and to prevent accidents or damage.
2. Torolàlana momba ny fiarovana
Tandremo hatrany ny fepetra fiarovana fototra mba hampihenana ny mety hisian'ny afo, fahatapahan-jiro ary ratram-po. Tehirizo ity boky ity mba hojerena amin'ny ho avy.
- Fiarovana ny faritra fiasana: Ataovy madio sy mazava tsara ny toeram-piasana. Ny faritra mikorontana na maizina dia miteraka loza. Aza mampiasa fitaovam-pamokarana amin'ny atmosfera mipoaka, toy ny fisian'ny ranon-javatra mirehitra, entona, na vovoka.
- Fiarovana herinaratra: Tsy maintsy mitovy amin'ny fantson-jiro ny plug-n'ny fitaovana elektrika. Aza manova mihitsy ny plug. Aza avela hikasika ny vatana amin'ny tany na zavatra miraikitra amin'ny tany toy ny fantsona, radiator, fatana fandoroana ary vata fampangatsiahana.
- Fiarovana manokana: Manaova fiarovana maso foana. Ampiasao fiarovana sofina rehefa mampiasa ny fitaovana mandritra ny fotoana maharitra. Mitafia akanjo tsara; aza manao akanjo na firavaka mivelatra. Arovy amin'ny zavatra mihetsika ny volo, ny akanjo ary ny fonon-tanana.
- Fitaovana fampiasana sy fikarakarana: Aza terena ny fitaovana herinaratra. Ampiasao ny fitaovam-pamokarana marina ho an'ny fampiharanao. Esory ny plug amin'ny loharanon-jiro alohan'ny hanaovana fanitsiana, fanovana kojakoja, na fitahirizana fitaovana herinaratra.
- Vibration: This tool features User Vibration Protection (UVP) to reduce vibration. However, prolonged use can still cause vibration-related injuries. Take regular breaks and use appropriate gloves.

6. Fikojakojana
Regular maintenance ensures the longevity and safe operation of your HiKOKI DH28PCY Rotary Hammer.
- Fanadiovana: Aorian'ny fampiasana tsirairay, diovy amin'ny fitaovana malefaka, damp lamba. Aza mampiasa akora simika mahery vaika na fanadiovana maloto. Tazony amin'ny vovoka sy ny potipoti-javatra ny varavarankelin'ny rivotra.
- fanosorana: The internal components are factory-lubricated. Refer to a qualified service center for any internal lubrication needs.
- Fijerena tady: Jereo tsy tapaka ny tariby herinaratra raha misy fahasimbana. Raha simba dia asaivo soloin'ny teknisianina mahay.
- fitahirizana: Tehirizo ao amin'ny toerana maina sy azo antoka ny fitaovana, tsy azon'ny ankizy.
