with proper equipment. Report
any deficiencies using the proper forms. See
DA PAM 738-750.
Perform PMCS each day vehicle is
operated. If vehicle is not being operated
regularly, start and run engine for approx-
imately 1/2 hour at least once a week. While
engine is running, exercise crane controls.
Perform only the PMCS required for running
engine and checking crane controls.
b. Perform weekly as well as before
operations PMCS and check fluid levels if:
(1) You are the assigned operator and
have not operated the item since the last
(2) You are operating the item for the
c. While you perform PMCS, have
checker tools with you and keep an eye
out for the following:
(1) Loose bolts. A loose bolt can be dif-
ficult to spot without using a wrench.
However, you can often identify loose bolts
by observing loose or chipped paint around
bolt head and bare metal or rust at its base.
Tighten loose bolts.
(2) Damaged welds. Damaged welds
may be detected by observing rust or chipped
paint where cracks occur.
(3) Frayed electrical wires and loose
connectors. Check electrical wiring for cracks
due to aging and exposed wires that could
cause an electrical short. Tighten loose
clamps and connectors.
Equipment operation is allow-
able with minor leakages (class
I or 11). Of course, you must
consider the fluid capacity in
the item/system being checked/
inspected. When in doubt, noti-
fy unit maintenance personnel,
When operating with class I or
class II leaks, continue to check
fluid levels as required in your
Class Ill leaks should be
reported to unit maintenance
Fluid leakage classifications
apply only to hull components.
(4) Fluid leakage. Leaks are divided into
three classifications. Compare leak with the
Seepage of fluid (as in-
dicated by wetness or
discoloration) not great
enough to form drops.
Leakage of fluid great
enough to form drops but
not enough to cause
drops to drip from item
Leakage of fluid great
enough to form drops that
fall from the item being
d. If your equipment does not perform as
required, refer to troubleshooting procedures
in chapter 3 for possible problems. Report
any malfunctions or failures on the proper DA
Form 2404, or refer to DA PAM 738-750.
If an assembly must be removed and/or
disassembled in order to perform PMCS, refer
to the maintenance procedures in chapter 3.
