  Warning

  • A hot engine and intake-air system can cause severe burns. Turn off the engine and wait until they are cool before removing the intake-air system.
  • Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious injuries or death and damage. Fuel can also irritate skin and eyes. To prevent this, always complete the "Fuel Line Safety Procedure".

  Caution

  • The PCM is built into the air cleaner cover. Applying excessive pressure to the cover could damage the PCM. Be careful not to put your hands on the PCM during the removal/installation. Removing the PCM from the air cleaner could damage the sealing or the circuitry. Do not remove PCM from the air cleaner.
