3. Wind tape around the tip of the air gun and apply air of approx. 150kpa (1.5kgf/cm² , 21psi) to the port of the camshaft. (Perform this order to release the lock pin for the maximum delay angle locking.)
  NOTE: When the oil splashes, wipe it off with a shop rag.
4. Under the condition of (3), turn the CVVT assembly to the advance angle side (the arrow marked direction in the illustration) with your hand.
