2. Varnostna navodila
Pri uporabi kosilnice vedno dajte prednost varnosti. Neupoštevanje teh navodil lahko povzroči resne poškodbe ali materialno škodo.
- Pred uporabo stroja preberite in razumejte vsa navodila.
- Otroke in hišne ljubljenčke držite stran od delovnega območja.
- Nosite ustrezno osebno zaščitno opremo (OZO), vključno z zaščito za oči, zaščito za sluh, trdno obutvijo in dolgimi hlačami.
- Inspect the area for objects that could be thrown by the blade before mowing. Remove stones, sticks, wires, and other debris.
- Kosilnice nikoli ne uporabljajte v mokri travi ali dežju.
- Gorivo dolivajte v dobro prezračevanem prostoru z ugasnjenim in ohlajenim motorjem. Izogibajte se razlitju goriva.
- Do not operate the machine if guards or safety devices are damaged or not in place.
- Always turn off the engine and disconnect the spark plug wire before performing any maintenance, cleaning, or clearing blockages.
- Kosite po pobočjih, nikoli navzgor in navzdol. Pri spreminjanju smeri na pobočjih bodite izjemno previdni.
3. Nastavitev in montaža
The HYUNDAI LM5103G M requires some assembly before first use. Follow these steps carefully:
- Razpakiranje: Previdno vzemite vse komponente iz embalaže. Preverite, ali so bile med transportom poškodovane.
- Sklop ročaja: Attach the upper handle to the lower handle, and then attach the complete handle assembly to the main unit. Secure all bolts and knobs firmly.
- Dodajanje motornega olja: The engine is shipped without oil. Fill the engine with the recommended type and amount of engine oil (refer to the engine manual for specifics, typically 0.6 liters of SAE 30 or 10W-30). Do not overfill.
- Dodajanje goriva: Fill the fuel tank with fresh, unleaded gasoline. Do not use E85 or other ethanol blends higher than E10. Ensure the fuel cap is securely tightened.
- Mulching Plug / Side Discharge Deflector: Decide whether to use the mulching function or side discharge.
- For mulching, ensure the side discharge deflector is closed and the mulching plug is inserted.
- For side discharge, remove the mulching plug and attach the side discharge deflector.


4. Navodila za uporabo
4.1. Zagon motorja
- Prepričajte se, da je žica vžigalne svečke dobro priključena.
- Move the throttle lever to the "START" or "CHOKE" position (if applicable).
- Press the primer bulb 3-5 times (if equipped) until fuel is visible in the bulb.
- Držite ročico zavore motorja ob ročaju.
- Pull the starter rope with a firm, steady motion until the engine starts. Do not let the rope snap back.
- Ko se motor zažene, postopoma premaknite ročico za plin v položaj "RUN".

4.2. Nastavitev višine košnje
The lawnmower features a central 6-fold height adjustment system, allowing cutting heights from 25 mm to 75 mm.
- Ugasnite motor in počakajte, da se rezilo popolnoma ustavi.
- Locate the height adjustment lever, typically near one of the wheels.
- Pull the lever outwards and move it to the desired height setting. Ensure all wheels are set to the same height.

4.3. Tehnike košnje
- Za najboljše rezultate kosite, ko je trava suha.
- Do not remove more than one-third of the grass height in a single pass.
- Za enakomerno pokritost rahlo prekrivajte košnje.
- When mulching, ensure the grass is not too long or wet to prevent clogging.
- The large, double ball-bearing wheels provide good mobility and are lawn-friendly, making it easy to maneuver.
5. Vzdrževanje
Redno vzdrževanje zagotavlja dolgo življenjsko dobo in optimalno delovanje vaše kosilnice.
5.1. Generalno čiščenje
- After each use, clean the underside of the mower deck to prevent grass buildup. Turn off the engine, disconnect the spark plug, and tilt the mower.
- Obrišite zunanjost z oglasomamp cloth. Do not use a high-pressure washer directly on the engine or electrical components.
5.2. Nega rezil
- Redno pregledujte rezilo glede ostrine in morebitnih poškodb. Topo rezilo trga travo, kar vodi v nezdravo trato.
- Sharpen or replace the blade as needed. Always use genuine HYUNDAI replacement parts.
- Pri rokovanju z rezilom nosite debele rokavice.

5.3. Vzdrževanje motorja
- Menjava olja: Motorno olje zamenjajte po prvih 5 urah delovanja, nato pa vsakih 25–50 ur ali letno, kar nastopi prej.
- Zračni filter: Redno čistite ali menjajte zračni filter, zlasti v prašnih pogojih.
- Vžigalna svečka: Svečko vsako leto preglejte in očistite. Zamenjajte jo, če je obrabljena ali umazana.
- Sistem goriva: At the end of the mowing season, either run the engine until it runs out of fuel or use a fuel stabilizer to prevent fuel degradation.
