Using the K - Tuned Cam Lock Tool is simple. First, find the corresponding holes on the cam pulse plate and tower of your K20A, K20Z, K24A, or K24Z cylinder head. Then, insert the tool through these holes to lock the cams. When handling the tool, hold it by the knurled aluminum knob for a good grip. Make sure the tool is fully inserted to ensure accurate cam locking. As for maintenance, keep the tool clean after each use. Wipe off any dirt or debris with a dry cloth. Store it in a dry place to prevent the steel pins from rusting. If you notice any damage to the pins or the knob, replace the tool to avoid inaccurate timing or potential breakage.
