SECTION II. PREVENTIVE MAINTENANCE CHECKS
AND SERVICES (PMCS)
Preventive Maintenance Checks and Services (PMCS)
means systematic caring, inspecting, and servicing of
equipment to keep it in good condition and prevent
breakdowns. The operators mission is to:
Be sure to perform PMCS each time the paving
machine is operated. Always do PMCS in the
same order so that it becomes a habit. With
some practice, anything wrong is quickly spotted.
Do BEFORE PMCS just before operating the
paving machine. Pay attention to WARNINGs
CAUTIONs, and NOTEs.
Do DURING PMCS while operating the paving
machine. During operation means to check the
paving machine and its related components
while it is actually operating. Pay attention to
WARNINGs, CAUTIONs, and NOTEs.
Do AFTER PMCS right after operating the
paving machine. Pay attention to WARNINGs,
CAUTIONs, and NOTEs.
Do WEEKLY PMCS once a week.
Use DA Form 2404 (Equipment Inspection and
Maintenance Worksheet) to record any faults
discovered before, during, or after operation that
cannot be immediately fixed. Do not record
faults that are immediately fixed.
maintenance during lubrication of the paving
machine. Perform other services when required
by organizational maintenance.
Do not use diesel fuel, gasoline, or
benzene (benzol) for general cleaning
procedures. Diesel fuel washdown is
only permitted for general cleaning of
the machine using the fuel washdown
system provided with the paving
Cleaning 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, and do
not breathe vapors. Keep away from
heat or flame. Never smoke when
using solvent; the flashpoint for Type
Mil 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 attention.
When using steam to clean, do not
point water or steam directly at any
electrical connections. Do not use a
high pressure steam supply system.
Damage to electrical system and
other components may occur.
The machine should be cleaned immediately after use.
Any asphalt materials or residue should be removed
from the surfaces of the machine as a general care
practice. A fuel spray washdown procedure is provided
in the maintenance section of this manual. Use this
procedure immediately after completing each paving
operation. General cleaning procedures are as follows:
(1) The paving machine may be steam cleaned
if extremely dirty. When cleaning the engine
cleaner cap assembly, and any other
(2) After cleaning allow engine to air dry. Do not
use compressed air to dry engine. Do not
run engine to decrease drying time.
When dry remove all component covers
before starting engine.
