WARNING

Let engine cool before removing radiator cap from radiator. Always turn cap slowly to first stop and allow pressure to escape

Compressed air used for cleaning purposes will not exceed 30 psi. Use only with effective chip guarding and personal protective

equipment (goggles/shield, gloves, and so forth).

Drycleaning solvent (P-D-680) is TOXIC and flammable. Wear protective goggles and gloves. Use only in a well-ventilated area.

Avoid contact with skin, eyes, and clothes. Do not breathe vapors. Keep away from heat or flame. Never smoke when using

solvent. Failure to do so may result in injury or death to personnel.
