Organizational Maintenance Instructions (Cont)
WARNING
Solvents used with a spray gun must be used in a spray booth with a filter. Face shield
must be used by personnel operating spray gun. Failure to comply may result in injury to
personnel.
g. LHS Assembly. Use a spray gun and solvent mixture for cleaning exterior of LHS assembly.
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.
CAUTION
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.
WARNING
·
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 III Drycleaning Solvent is 200_F
(93_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 10, Appendix F). Run a thin, flexible wire through oil passages to make sure
they are not clogged. Use a pressure spray gun and drycleaning solvent (Item 18, Appendix F) 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 5, Appendix F)
moistened with drycleaning solvent (Item 18, Appendix F).
k. Hydraulic System. When cleaning hydraulic system parts use drycleaning solvent P-D-680.
Clean and dry parts thoroughly to make sure no residue remains. If a coating preservative is required
before assembly, apply a light film of lubricating oil (Item 10, Appendix F). If petroleum-free solvents are
not available, use the same hydraulic fluid as used in the truck’s system.
