2-43. GENERAL CLEANING INSTRUCTIONS (CONT).
Solvents used with a spray gun must be used in a spray booth with filter. Face shield must be
used by personnel operating spray gun. Failure to comply may result in injury to personnel.
g.
Engine, Cab and Body. Use a spray gun and solvent mixture for cleaning exterior of engine, cab and body.
Allow mixture to remain on item surface for 10 minutes before rinsing. Rinse with hot water under 80 to 120 pounds
of pressure, if available. An ordinary garden hose with nozzle may be used if other equipment is not available. Rinse
thoroughly.
To prevent corrosion, parts should be dipped in rust preventive within two hours of degreasing.
h.
Degreasing Machine. A degreasing machine may be used to remove heavy grease and oil from metal parts.
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.
Never use fuel to clean parts. Fuel is highly flammable. Serious personal injury could result
if fuel ignites during cleaning.
i.
Passages. After degreasing, check all oil passages and cavities for dirt or blockage before coating with
lubricating oil (Item 54, Appendix C). Run a thin, flexible wire through oil passages to make sure they are not clogged.
Use a pressure spray gun and drycleaning solvent (Item 87, Appendix C) to clean dirty passages.
j.
Electrical Parts. Electrical parts, such as coils, junction blocks and switches should not be soaked or sprayed
with cleaning solutions. Clean these parts with a cleaning cloth (Item 31, Appendix C) moistened with drycleaning
solvent (Item 87, Appendix C).
