      ------ WARNING! ------

      Use caution when you are using isopropyl alcohol. Avoid prolonged skin contact with isopropyl alcohol.

      Vapors may be harmful if inhaled. Use only in a well ventilated area. Do not smoke while using isopropyl alcohol.

      Isopropyl alcohol is flammable. Do not use near an open flame or near welding operations. Keep isopropyl alcohol away from heated surfaces exceeding 482°C (900°F).

      ----------------------

    1. Lubricate new O-ring seals (6) with Tooling (B) prior to installation.
