excessive heat and don't smoke when using it. Failure to do so

could cause serious injury. If you become dizzy while using

cleaning solvent, get fresh air immediately, and get medical

attention. If contact with skin or clothes is made, flush with large

amounts of water. If contact with eyes is made, wash eyes with

water immediately, and obtain medical aid immediately.
