The Army Maintenance Management System (TAMMS) Users Manual

mileage/kilometers or hours in a 12-month period may have all unit (-20) and direct support services (-34) extended
(see (3) below for low-usage criteria).
(b) Use.
1. Prior to placing equipment into low usage, all scheduled services and lubrication listed in the equipments -20 and
-34 TMs/LOs (W, M, Q, S, A, E, B) is performed. Equipment requiring an E—18-month service and B—biennial (2
years) service is performed in accordance with the appropriate TM/LO at regularly scheduled service intervals, using
the E or B symbol. After equipment is placed in the low-usage program, all services and lubrications, except the E and
B, are combined with the annual services using the A symbol on DD Form 314. The date, miles/kilometers, and hours
are entered in the Remarks block of DD Form 314 when equipment is entered in the low-usage program.
2. Equipment that exceeds the specified criteria at any time during the 12-month period immediately returns to
scheduled servicing at normal TM/LO intervals, to be scheduled from the information that was entered in the Remarks
block of DD Form 314.
3. Servicing, evaluating, and exercising of recoil mechanisms and tubes are accomplished in accordance with
applicable technical bulletins and manuals.
4. All communications equipment/subsystems mounted or not mounted and equipment/subsystems mounted in
shelters are serviced annually with the primary system.
5. Low-usage servicing is not utilized for equipment under warranty, armament equipment and equilibrating systems,
ATC, and fire control components of combat vehicles and missile systems.
6. Operator/crew level (-10) maintenance intervals in TMs/LOs are not changed because of low usage.
7. AOAP is not extended; see chapter 4.
(c) Vehicle storage. When a vehicle is stored in Army Prepositioned Stocks or low usage, no AOAP sampling is
required until the vehicle is scheduled for operational use.
(d) AOAP sampling. For units (-20 and -34) scheduled services (B Biennial), equipment has engine oil and
transmission fluid (enrolled in AOAP) sampled prior to operation or the changing of any oil/lubricants. This sample
helps determine the condition of oil/lubricants prior to operating equipment. Oil analysis is also performed during each
annual maintenance cycle and immediately upon removing the vehicle from war reserve or low-usage program. Once
the equipment returns to normal operation, sampling intervals established in chapter 4 apply. Vehicles in low usage that
require a B service on differentials or gearbox are checked for contamination. If contamination exists, these components
are drained, flushed, and refilled to the full mark.
(e) Criteria.
1. Light tactical vehicles, trailers assigned to prime movers, and trailers without assigned prime movers that
accumulate or are anticipated to accumulate fewer than 3,000 miles/4,800 kilometers in a 12-month period.
2. Heavy tactical vehicles that accumulate fewer than 1,200 miles/1,935 kilometers in a 12-month period.
3. Combat vehicles (except armament, equilibrating system, and fire control components), missile systems (except
fire control components), material handling equipment (MHE), and construction equipment anticipated to accumulate
fewer than 500 miles/800 kilometers or 125 hours in a 12-month period.
4. Generators, pumps, air compressors, support equipment (reverse osmosis water purification units, bath units, and
so on), watercraft, rail equipment, power-driven NBC equipment (for example, decontamination apparatus), enginedriven
heaters, and air conditioners anticipated to accumulate fewer than 75 hours of operation in a 12-month period.
5. Communication equipment anticipated to accumulate fewer than 75 hours of operation in a 12-month period.
6. NBC equipment (for example, protective mask, M11 decon app, and so on) anticipated to accumulate fewer than
75 hours of use in a 12-month period.
7. Tentage and canvas items. Those not used are erected annually. Immersion heaters, mobile kitchen trailers, bakery
ovens, field ranges and space heaters/stoves. Those not used are serviced annually.
8. Small arms and crew-served weapons (machine guns, mortars, and so on). Those maintained in a humiditycontrolled
room and not removed for any reason at any time during the year are serviced annually. All equipment,
except that stated in 3–9b(10)(b)5, is inspected/operated/exercised by operators semiannually. Inspection/operate/
exercise includes—
a. Perform all Before (B) through Monthly (M) PMCS checks per equipment operators TM.
b. Tactical (including trailers) and combat vehicles are to be driven at least 5 miles to insure their performance is
within parameters listed in the operators TM. Vehicles equipped with radios have Before (B) through Monthly (M)
PMCS performed per the communication equipment operators TM.
c. Construction, engineer, and material handling equipment, wreckers, and combat vehicles are operated sufficiently
to ensure hydraulic systems reach normal operating temperature and equipment is mission capable.
d. Generators, air compressors, support equipment, pumps, and power-driven NBC equipment are operated for 30
minutes under load or 1 hour no load.
e. Small arms and crew served weapons are inspected, without leaving humidity-controlled room, for rust and
corrosion. High-humidity area inspections may be required more often.
f. Visual inspections are performed by the operator/crew to ensure lubricant is present on all lubrication points.
