A lithium battery is used in this equipment, and is potentiallyhazardous if misused or tampered with. The battery containspressurized sulfur dioxide gas which is toxic. The followingprecautions must be strictly observed to prevent possibleinjury to personnel or damage to equipment:

Do not heat, incinerate, crush, puncture, disassemble, orotherwise abuse the battery in any way that may cause it torupture.

Do not short-circuit the battery, test for capacity, or attemptto recharge.

Do not use any battery showing signs of damage, such as bulging,swelling, disfigurement, a brown liquid in the plastic wrap, ora swollen plastic wrap.

Do not bypass internal fuse or replace with a fuse of adifferent rating.

Do not store battery in unused equipment for more than 30 days.

Do not dispose of lithium batteries with ordinary trash/refuse.Turn in batteries to your local Defense Reutilization andMarketing Office.

Turn off the equipment immediately if you detect the batterycompartment becoming unduly hot, hear battery venting (hissingsound), or smell irritating sulfur dioxide gas. Remove anddispose of the battery only after it is cool to touch.

In the event of a fire near a lithium battery, rapid cooling ofthe battery is important. Flood the equipment with water oruse a carbon dioxide extinguisher. Control of the equipmentfire and cooling may prevent the battery from venting andpotentially exposing lithium metal. In the event that lithiummetal becomes involved in fire, the use of a graphite basedClass D fire extinguisher is recommended, such as Lith-X orMet-L-X. Do not use a Halon type fire extinguisher on alithium battery fire.

Remove the battery when the voltage drops below 20 volts underload (or equipment does not operate properly) and replace witha new battery.

If there is a safety incident, or if you believe a safetyhazard exists, notify your local safety officer.

Long-lasting because they can be recharged many times on the TOW batterycharger. To recharge battery assemblies, see TM 9-6130-470-12.

Easily removed from and installed in the missile guidance set.

Has enough energy for at least 50 missile firings or training exerciseswhen fully charged.

Can be stored at temperatures ranging from -50°C (-60°F) to+50°C (+122°F) without damage. Even though a battery may eventually loseall or part of its charge through self discharge, it can be returned toservice on the TOW battery chargers.

Charge retention (the ability of a stored battery to retain its energyonce it has been charged) is both time and temperature dependent. Tominimize this self discharge it is recommended that batteries be stored atlowest possible temperature.

Has acceptable life span of three to five years.

Battery Charge Retention Storage Schedule

Hours Storage periodSchedule Storage temperature per day days

1 25 ±2.8°C (77 ±5°F) 24 302 37.8 ±2.8°C (100 ±5°F) 20

51.6 ±2.8°C (125 ±5°F) 4 143 65.5 ±2.8°C (150 ±5°F) 24 3

The TOW battery must be recharged every 30 days or as defined in scheduleabove to maintain proper charge.

The TOW battery will not be adversely affected if stored on the groundor on metal, concrete, or wood shelves.

Injury to the gunner and damage to the equipment can occur ifthe TOW 2 system is fired at angles greater than 20 degrees orless than -20 degrees for all firing positions except over thecargo/loader’s door. If firing over the cargo/loader’s door,firing angles should not exceed +20 degrees or -13 degrees.

Pressure waves and flying debris can cause injury to personneland equipment damage.

There are restrictions to the elevation angle in which a missile may be firedfrom a HMMWV launcher. The restricted firing angles are those greater than20 degrees or less than -20 degrees for all firing positions except over the cargo/loader’s door. If firing over the cargo/loader’s door, firing angles should notexceed +20 degrees or -13 degrees. The HMMWV may be struck by the missile orseverely damaged by the back blast if the launcher is pointed in a restrictedposition while being fired. In addition, personnel may be injured.

An elevation and depression limiter assembly is provided with the HMMWV as a safetydevice. When the elevation and depression stops are in the “up” position and pinned,firing angle limitation will be +20 degrees and -10 degrees.

2 - 9 0 . AIR PRESSURE

The air is “thinner” at higher altitudes. The missile will require more timeto correct for a steer error at high altitude than for the same steer error ata low altitude. Since missile steering is done automatically by the weapon sys-tem, the gunner only has to track the target through the day sight tracker. TheTOW 2 Weapon System will operate properly up to an altitude of 10,000 feet.

2 - 9 1 . HIGH WINDS

NOTE

• Firing missile into a high cross wind can causeslight tracking problems.

• Generally, however, the TOW 2 Weapon system willautomatically adjust for the effects of cross windson the TOW missile.

A. The launcher should be shielded from high winds if possible to avoidtracking problems.

B. Try to select targets either up or down wind from the launcher.

2 - 9 3 . OVER WATER (CONT)(Sheet 3 of 6)

The missile firing range for the given heights above water is determined by usingthe following four graphs. To use the graphs, first determine the height abovewater of the TOW 2 launcher. Put a mark at the height on the left-hand columnof the graph. Then determine the height above water of the target. Put a markat that height on the right-hand column of the graph. Connect the two markswith a straight line. Find where the line crosses the center column. Thereading at that point on the center column tells the maximum range the missilecan travel without getting too close to the water.

NOTE

If you are measuring in feet, use the graph in step 5or step 8. If you are measuring in meters, use thegraph in step 6 or step 7.

Use to find range of TOW missile BGM-71A, BGM-71A-2, BGM-71A-2A, BTM-71A,BTM-71A-2, BTM-71A-2A or BTM-71A-2B in feet. For example, line (a) on the graphshows the missile can hit the target across an 8000-foot strip of water whenlauncher is 12 feet above water and target is 36 feet above water. Line (b)shows that when the launcher is 75 feet above water and the target is 3 feetabove water, the missile can hit the target across a 9840-foot strip of water.

b. Storage

(1) Follow good storage practice. Protect encased missiles from sun, rain, andmoisture. Use at least six inches of dunnage under the wooden overpacks. Putwaterproof cover over and around stack of missiles. Shelter should be big enoughto have good air circulation. Shelter and encased missiles should be easy to getat so missiles will stay in good condition and be ready for immediate use.

(2) All encased missiles in storage area must be stored with nose ends pointingin the same direction. Direction of storage should permit the least danger topersonnel or equipment in case of explosionor fire.

(3) Storage area should provide the most protection from damage, corrosion, orwearing away. Storage temperature must be between -53.9 and +68.3°C (-65 to155°F). The storage area should:

(a) Be on level ground and have the most protection from the weather.

(b) Have good drainage.

(c) Be arranged so that inspection of missiles can be doneas required.

(d) Meet quantity-distance requirements. Refer to TM 9-1300-206 for generalinformation on storage of ammunition. Missiles are encased and stored in woodenoverpacks. Inspection must be done on encased missiles before they are stored.Storage data is included in table 4-2.

MAINTENANCE ALLOCATION CHART

B-1. GENERAL

This appendix contains the maintenance allocation chart which shows the lowest levelof maintenance authorized to do certain maintenance operations.

B-2. MAINTENANCE FUNCTIONS

The maintenance functions will be limited to and defined as follows:

a. Inspect. To determine the serviceability of an item by comparing itsphysical, mechanical, and/or electrical characteristics with establishedstandards through examination (e.g., by sight, sound, or feel).

b. Test. To verify serviceability by measuring the mechanical, pneumatic,hydraulic, or electrical characteristics of an item. and comparing thosecharacteristics with prescribed standards.

c. Service. Operations required periodically to keep an item in properoperating condition, i.e., to clean (includes decontaminate, whenrequired), to preserve, to drain, to paint, or to replenish fuel,lubricants, chemical fluids, or gases.

d. Adjust. To maintain or regulate, within prescribed limits, by bringinginto proper or exact position, or by setting the operating characteristicsto specified parameters.

e. Aline. To adjust specified variable elements of an item to bring aboutoptimum or desired performance.

f. Calibrate. To determine and cause corrections to be made or to be adjustedon instruments or test, measuring, and diagnostic equipments used inprecision measurement. Consists of comparisons of two instruments, one ofwhich is a certified standard of known accuracy, to detect and adjust anydiscrepancy in the accuracy of the instrument being compared.

g. Remove/Install. To remove and install the same item when required toperform service or other maintenance functions. Install may be the act ofemplacing, seating, or fixing into position a spare, repair part, or module(component or assembly) in a manner to allow the proper functioning of anequipment or system.

h. Replace. To remove an unserviceable item and install a “serviceablecounterpart in its place. “Replace” is authorized by the MAC and is shownas the 3rd position code of the SMR code.

i. Repair. The application of maintenance services, including faultlocation/troubleshooting, removal/installation, and disassembly/assemblyprocedures, and maintenance actions to identify troubles and restoreserviceability to an item by correcting specific damage, fault,malfunction, or failure in a part, subassembly, module (component orassembly), end item, or system.

B-1

TM 9-1425-450-12

j. Overhaul. That maintenance effort (service/action) prescribed to restorean item to a completely serviceable/operational condition as required bymaintenance standards in appropriate technical publications (i.e., DMWR).Overhaul is normally the highest degree of maintenance performed by theArmy. Overhaul does not normally return an item to like new condition.

k. Rebuild. Consists of those services/actions necessary for the restorationof unserviceable equipment to a like new condition in accordance withoriginal manufacturing standards. Rebuild is the highest degree ofmateriel maintenance applied to Army equipment. The rebuild operationincludes the act of returning to zero those age measurements (hours/miles,etc.) considered in classifying Army equipment/components.

B-3. COLUMN ENTRIES

An explanation of columns used in the maintenance allocation chart will be limitedto those shown. Entries for these columns are explained below:

a. Column 1. Group Number. Column 1 lists group numbers, the purpose ofwhich is to identify components, assemblies, subassemblies, and moduleswith the next higher assembly.

b. Column 2. Component/Assembly. Column 2 contains the noun names ofcomponents, assemblies, subassemblies, and modules for which maintenance isauthorized.

c. Column 3. Maintenance Functions. Column 3 lists the functions to beperformed on the item listed in Column 2.

Column 4.d. Maintenance Category. Column 4 specifies, by the listing of a“work time” figure in the appropriate subcolumn(s), the lowest level ofmaintenance authorized to perform the function listed in Column 3. Thisfigure represents the active time required to perform that maintenancefunction at the indicated category of maintenance. If the number orcomplexity of the tasks within the listed maintenance function vary atdifferent maintenance categories, appropriate “work time” figures will beshown for each category. The number of man-hours specified by the “worktime” figure represents the average time required to restore an item(assembly, subassembly, component, module, end item or system) to aserviceable condition under typical field operating conditions. This timeincludes preparation time, troubleshooting time, and qualityassurance/quality control time in addition to the time required to performthe specific tasks identified for the maintenance functions authorized inthe maintenance allocation chart.

e. Column 5. Tools and Equipment. Column 5 specifies by code, those commontool sets (not individual tools) and special tools, test, and supportequipment required to perform the designated function. These are identi-fied in the Tool and Test Equipment Requirements table following the MAC.

f. Column 6. Remarks. Column 6 contains an alphabetic code which leads toremarks which are pertinent to the item opposite the particular code.Remarks are located “in the Remarks table following the MAC:
