  3. Sätt tillbaka oljeavtappningspluggen och dra åt den ordentligt.
  4. Using the provided funnel, slowly add the recommended type and amount of new engine oil (refer to your generator manual for exact specifications). Do not overfill.
  5. Kontrollera oljenivån med oljestickan.

Step 2: Oil Filter Replacement

  1. Locate the old oil filter. Place a rag or small pan underneath to catch any drips.
  2. Use an oil filter wrench to loosen and remove the old filter.
  3. Apply a thin film of new engine oil to the rubber gasket of the new oil filter.
  4. Screw on the new oil filter by hand until the gasket makes contact with the engine. Then, tighten an additional 1/2 to 3/4 turn. Do not overtighten.

Step 3: Air Filter Replacement

  2. Open the housing and carefully remove the old air filter. Note its orientation.
  3. Insert the new air filter, ensuring it is seated correctly within the housing.
  4. Stäng och säkra luftfilterhuset.

Step 4: Spark Plug Replacement

  4. Thread the new spark plug into the cylinder head by hand to prevent cross-threading.
  5. Tighten the spark plug with the socket wrench. If using a torque wrench, tighten to the specification in your generator manual (typically around 18-22 ft-lbs). If not, tighten until snug, then an additional 1/4 to 1/2 turn.
