Drycleaning Solvent (P-D-680) is TOXIC and flammable. Wear protective goggles, face
shield, and gloves; use only in a well-ventilated area; avoid contact with skin, eyes, and
clothes, and do not breathe vapors. Keep away from heat or flame. Never smoke when
using solvent; the flashpoint for Type II Drycleaning Solvent is 140 degrees F (60 degrees
C) and Type III Drycleaning Solvent is 200 degrees F (93 degrees C). Failure to do so may
result in injury or death to personnel.
If personnel become dizzy while using cleaning solvent, immediately get fresh air and
medical help. If solvent contacts skin or clothes, flush with cold water. If solvent contacts
eyes, immediately flush eyes with water and get immediate medical attention.
Brake shoes may be covered with dust. Breathing this dust may be harmful to your health.
Do not use compressed air to clean brake shoes. Wear a filter mask approved for use against
brake dust. Failure to comply may result in injury or death to personnel.
Clean brake drums (1) of all dirt and brake
lining material with drycleaning solvent.
Measure inside diameter of brake drum in at
least three equally spaced points. If
measurement at any point exceeds 16 5/8 in.
