2-8. GENERAL PROCEDURES.
a.
General Cleaning Instructions.
Dry cleaning solvent (SD2) (item 16,
appx C) is toxic and flammable.
Wear protective goggles and gloves
and use only in well-ventilated areas.
(1)
Use dry cleaning solvent (item 16,
appx C) to clean grease, oil, or dirt from all
metal parts. If a water hose is available, it
may be used to take off heavy dirt. If a steam
cleaner is available, it may be used to take off
any remaining dirt. Make sure steam or water
does not enter roadwheel bearings, shock ab-
sorbers, optics, hatches, and powerpack open-
ings. After water or steam cleaning, lubricate
vehicle. If water is found, drain and refill.
Clean grease, oil, or dirt from all metal parts
with dry cleaning solvent, cleaning compound,
or equivalent.
(2)
Use mild soap and water to clean or
wash parts not made of metal. Rinse thorough-
ly after cleaning with water and then dry.
(3)
Remove rust or dirt from fine-ma-
chined surfaces with dry cleaning solvent (item
16, appx C) and crocus cloth (item 10, appx C),
if necessary. Do not use any other material.
Be careful not to change the dimensions of
parts when rubbing off rust. Coat bare metal
surfaces, after cleaning, with CLP (item 8, appx
c).
(4)
Nameplates, caution plates, and in-
struction plates may rust quickly. When they
are rusty, clean parts and coat them with CLP
(item 8, appx C).
b.
Precautions.
The following precautions
will help prevent personal injury or damage to
equipment.
(1)
Do not spill solvent, fuel, or lubricants
on rubber parts. Solvent, fuel, and lubricants
may damage rubber parts.
(2)
Do not use turbine fuel, diesel fuel,
gasoline, paint thinner, or benzene (benzol) for
cleaning. These liquids may cause personal
injury.
(3)
Always wear protective clothing when
using solvent. Solvent may dry skin.
Improper use of high pressure water
hose or steam cleaner can damage
seals and electrical components re-
sulting in equipment failure. Use high
pressure water only on suspension
system.
(4)
Do not clean inside hull with high
pressure steam or air. Some parts inside hull
may rust or be damaged.
(5)
When washing outside of vehicle,
close and lock all hatches. Cover periscope
with plastic sheets. Remove covers after wash-
ing.
(6)
Do not use polishing cloths, liquids,
pastes, or other rough cleaners to clean instru-
ment lenses or periscope lenses. Use lens
paper to clean lenses. Take off fingerprints, oil,
and dirt with lens cleaning compound and lens
paper.
(7)
If anything looks wrong and cannot
be fixed, report it on DA Form 2404. If some-
thing looks dangerous or may cause equipment
damage, report it to the maintenance supervisor
right away.
c.
Services. Services
performed by the
unit maintenance mechanic consist of the fol-
lowing tasks:
(1)
Adjusting.
Make all necessary adjust-
ments and alinements.
(2)
Servicing.
This usually means drain-
ing and refilling units with oil and changing or
cleaning oil filters, fuel filters, and air cleaners.
