Betjeningsvejledning
1. Start af motoren
- Ensure the pump is properly primed and all hoses are connected.
- Place the suction hose with the strainer into the water source.
- Drej brændstofventilen til 'ON'-positionen.
- Flyt chokerhåndtaget til 'CHOKE'-positionen (hvis motoren er kold).
- Drej motorkontakten til 'ON'-positionen.
- Træk fast og jævnt i rekylstarterhåndtaget, indtil motoren starter.
- Når motoren starter, skal du gradvist flytte chokerhåndtaget til 'RUN'-positionen.
2. Under drift
Monitor the pump for consistent water flow and listen for any unusual noises. Ensure the suction hose remains submerged in water to prevent the pump from running dry, which can cause damage.
3. Standsning af motoren
- Drej motorkontakten til 'OFF'-positionen.
- Drej brændstofventilen til 'OFF'-positionen.
- Allow the engine to cool before handling or storing.
Opretholdelse
Regelmæssig vedligeholdelse sikrer optimal ydeevne og forlænger pumpens levetid.
Motorolie
Kontroller motoroliestanden før hver brug. Skift olien efter de første 5 driftstimer, og derefter hver 50. time eller årligt, alt efter hvad der kommer først.
Luftfilter
Inspect the air filter regularly and clean or replace it as needed, especially when operating in dusty conditions.
Tændrør
Inspect the spark plug annually or every 100 hours. Clean or replace if necessary, ensuring the correct gap.
Pump Housing and Impeller
Periodically inspect the pump housing and impeller for debris or wear. Clean out any blockages to maintain efficient flow.
Opbevaring
For long-term storage, drain the fuel tank and carburetor. Remove the spark plug and pour a small amount of engine oil into the cylinder, then pull the recoil starter a few times to distribute the oil. Clean the exterior of the pump and store it in a dry, protected area.
Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Motoren vil ikke starte | No fuel, old fuel, low oil, choke position incorrect, engine switch off, fouled spark plug | Add fresh fuel, check oil level, adjust choke, turn engine switch ON, clean/replace spark plug |
| Pump not moving water | Not primed, air leak in suction hose, clogged strainer, suction hose not submerged | Prime pump, check hose connections, clean strainer, ensure suction hose is fully submerged |
| Reduceret vandgennemstrømning | Partial blockage in hoses or impeller, air leak, worn impeller | Inspect and clear blockages, check hose connections, contact service for impeller inspection |
| Motoren kører ujævnt | Gammelt brændstof, snavset luftfilter, forkert tændrørsafstand | Drain and replace fuel, clean/replace air filter, adjust/replace spark plug |
