• Do not use any tools to disconnect the quick connector.

• Keep the resin tube away from heat. Be especially careful

when welding near the tube.

• Prevent any acid liquids such as battery electrolyte, from

getting on the resin tube.

• Do not bend or twist the resin tube during connection. 

• Do not remove the remaining retainer on the hard tube (or
