The parts and oil are at high temperature immediately after the engine is stopped, and may cause burns. Wait for the
temperature to go down before starting the work.
When removing the oil filler cap, turn it slowly to release the internal pressure, then remove it.
Refill capacity: 77.5 liters (20.48 US gal) (including oil in the brake oil tank and each filter case)

level on sight gauge (G), but this does not indicate any
abnormality.
