7.2 CHANGING THE OIL
WARNING!
Used motor oil can cause skin irritations if left in long-term
contact with skin. Thoroughly wash off used oil as soon as
possible with soap and water.
Do not dispose of used oil in drains or on soil. Local service
shops provide environmentally-friendly disposal methods.
Drain the oil rapidly and completely while the engine is still warm.
1. Remove the oil maintenance panel, remove the oil dipstick and open the
drain hole access plug. Place an oil collection pan underneath.
2. Loosen the interior rubber plug by pulling on it from the top (shown from
below here) to allow oil to drain down into the pan.
3. Loosen the oil drain bolt and allow oil to drain completely.
4. Replace the oil drain bolt and fill with fresh oil to the maximum oil mark.
Check the oil level by reinserting the dipstick
without rethreading it.
5. Reinsert the dipstick and tighten securely. Replace the bottom rubber drain
plug as well as the side panel oil drain bolt access rubber bung. Finally
replace the oil maintenance panel.
