Allow engine to cool before performing troubleshooting maintenance. If necessary use insulated pads

and gloves. Hot engine components will burn and cause injury to personnel.

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
