Cleaning solvent, P-D-680, is TOXIC and
flammable. Wear protective
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 IH cleaning solvent is
200°F (93,3°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, flush
eyes with water and get immediate medical
When cleaning underhood areas, engine must
be COLD (same temperature as outside air).
DO NOT point water or steam at any electrical
connection. DO NOT point water stream
directly at radiator fins. DO NOT use high
pressure water supply system. Damage to
components may result.
Use only the authorized cleaning
solvents or agents listed in Appendix
a. The paving machine should not be washed right
before an inspection. Certain problems, such as
oil, hydraulic, or coolant leaks may not show
after a wash.
b. Cleaning engine compartment areas:
(1) When using water to clean the engine
compartment, always cover alternators and air cleaner
inlet using waterproof materials. Use water pressure and
volume similar to standard household type water supply
system [45 to 70 psi (310 to 483 kPa)].
(2) After cleaning, allow engine to air dry. Do not
use compressed air to dry engine. Do not run engine to
decrease drying time.
(3) Remove all covers before starting engine.
Keep cleaning solvents, diesel fuel, and
lubricants away from rubber or soft plastic
parts. They will deteriorate the material.
PRESERVATIVES AND LUBRICANTS.
All lubrication of the Paving Machine will be in
accordance with LO 5-3895-373-12 Lubrication Order.
It is necessary to know how fluid leakage affects the
types/classes of leakage you must know to be able to
determine the status of the paving machine. Learn these
leakage definitions; when in doubt notify your supervisor.
Paving machine operation must be halted if any steady
stream leak of hydraulic oil is detected.
Equipment operation is allowable with
Consideration must be given to fluid
checked/inspected. When in doubt, notify
When operating with Class I or H leaks, continue to
check fluid levels as required by PMCS.
Immediately report Class m leaks to supervisor.
a. Class I Seepage of fluid (as indicated by
wetness or discoloration) not great enough to
b. Class II Leakage of fluid great enough to form
drops, but not enough to cause drops to drip
from item checked/inspected.
c. Class III Leakage of fluid great enough to form
drops that fall from item checked/inspected.
