Removal
• When working on high voltage system, the work should be carried by technicians who have completed the relevant training. It is because that lack of knowledge of the high voltage system can lead to serious accidents due to electric shock or electric leakage.
• When working a high voltage system, the technician must be recognized and observe "General Safety Information and Caution". If do not follow, serious accidents like electric shock and short circuit are caused.
• When working on high voltage system, make sure to check the Personal Protective Equipment (PPE) and high voltage shut-off procedures.
• Use a fender cover to protect the painted surface.
• Be careful not to damage the connector when disconnecting.
• When disconnecting a quick connector, refer to the following according to the type of quick connector.[Type A]- Remove the while pressing the quick connector clamp (A) in the direction of the arrow.- Do not touch the rubber seal (B) inside the hose.
