IMPORTANT! Paint once contained lead as a traditional ingredient. Contact with the dust from the removal of such paint is toxic and must therefore be avoided. The following action must be taken before using the machine as a sander:

  • The user must determine potential hazards relating to age of paint to be removed. (Modern paints do not have lead content).
  • DANGER! Keep all persons and pets away from the working area. The following are particularly vulnerable to the effects of lead paint dust: Expectant women, babies, and children.
  • We recommend personal protection by using the following safety items:
    • Paint Spray Respirator (Sealey ref. SSP1699)
    • PE Coated Hooded Coverall (Sealey ref. SSP266).
    • Latex Gloves (Sealey ref. SSP24).
  • Take adequate measures to contain paint dust, flakes and scrapings. Wear safety equipment, as in (3) above and thoroughly clean all areas when task is complete.
