Sikkerhetsinformasjon
ADVARSEL: Unnlatelse av å følge disse sikkerhetsinstruksjonene kan føre til alvorlig skade eller død.
- Drivstoffsikkerhet: Gasoline is highly flammable. Always refuel in a well-ventilated area with the engine off and cool. Do not smoke or allow open flames near the engine. Store fuel in approved containers.
- Eksosgasser: Engine exhaust contains carbon monoxide, a colorless, odorless, and deadly gas. Operate the engine only in well-ventilated outdoor areas. Never operate indoors.
- Varme overflater: Motoren og eksosanlegget blir svært varme under drift og forblir varme en stund etter at de er slått av. Unngå kontakt for å unngå brannskader.
- Bevegelige deler: Keep hands, feet, hair, and clothing away from moving parts such as the flywheel and recoil starter to prevent entanglement.
- Elektrisk sikkerhet: Do not touch electrical components while the engine is running or during starting. Ensure all connections are secure.
- Barn og kjæledyr: Hold barn og kjæledyr unna motoren, spesielt under drift.

3. Etterfylling av motorolje
The engine is shipped without oil. Fill the crankcase with the recommended type and amount of engine oil. Refer to the specifications section for oil type and capacity. Do not overfill.
4. Fylle på drivstoff
Use fresh, clean, unleaded gasoline with an octane rating of 87 or higher. Do not use E85 fuel. Fill the fuel tank carefully, avoiding spills. Do not fill above the fuel filter screen.
5. Pre-Start Checks
Before each use, check the engine oil level, fuel level, and ensure all fasteners are tight. Inspect the air filter and clean if necessary.

Betjening av motoren
1. Startprosedyre
- Ensure the engine is on a level surface.
- Open the fuel valve (if equipped).
- Move the choke lever to the 'CHOKE' position (cold engine). For a warm engine, set to 'RUN'.
- Flytt gasspaken til «RASK»-posisjonen.
- Grasp the recoil starter handle firmly and pull slowly until resistance is felt, then pull quickly and smoothly to start the engine.
- Når motoren starter, flytt chokehendelen gradvis til «RUN»-posisjonen etter hvert som motoren varmes opp.
2. Stopping Procedure
- Move the throttle lever to the 'SLOW' or 'IDLE' position.
- Vri motorbryteren til «AV»-posisjon.
- Close the fuel valve (if equipped) for storage or extended periods of non-use.

Vedlikehold
Regular maintenance is crucial for the longevity and performance of your engine. Always perform maintenance with the engine off and cool, and disconnect the spark plug wire to prevent accidental starting.
- Oljeskifte: Skift motorolje etter de første 5 driftstimene, deretter hver 50. time eller årlig, avhengig av hva som inntreffer først.
- Luftfilter: Inspiser og rengjør luftfilteret hver 25. time eller oftere i støvete forhold. Skift ut hvis det er skadet.
- Tennplugg: Inspect the spark plug every 100 hours. Clean or replace as needed and ensure proper gap.
- Drivstoffsystem: Drain the fuel tank and carburetor if storing the engine for more than 30 days. Use a fuel stabilizer if draining is not possible.
- Generell rengjøring: Keep the engine clean from dirt and debris, especially around cooling fins and air intake areas.
Feilsøking
| Problem | Mulig årsak | Løsning |
|---|---|---|
| Motoren vil ikke starte | No fuel, stale fuel, incorrect choke position, fouled spark plug, low oil level | Add fresh fuel, adjust choke, clean/replace spark plug, add oil |
| Motoren går tøft | Dirty air filter, stale fuel, incorrect spark plug gap, carburetor issues | Clean air filter, replace fuel, adjust spark plug gap, consult service center |
| Tap av kraft | Dirty air filter, low oil, engine overheating, worn components | Clean air filter, check oil, ensure proper ventilation, consult service center |
