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.

Wash the cylinder bores with drycleaning
solvent. Use a nylon brush to clean all oil
passages.
Build up of deposits in coolant
passages can cause engine
overheating. Excessive deposits
can be cleaned in an acid tank,
but the cam bushing must be
removed first (Para 7-7). Failure
to follow this procedure could
cause damage to the equipment.
(3)
Make sure coolant passages are clean.
High pressure steam can blow
particles into eyes, can cause
severe burns, and creates
hazardous noise levels. Eye,
skin, and hearing protection is
required.

Steam clean cylinder block. Ensure oil and
water galleries are cleaned thoroughly.
