RADIATION HAZARD

TM 9-2350-222-20-2-3-2

Azimuth dial pointers in indicator may be tipped with radioactive material. This becomes dangerous when

dial window is broken or removed. When this happens, make repairs as soon as possible.

If dial window is broken or removed, all maintenance must be done at depot level only, except replacement

of lamps or replacement of whole indicator unit.

Protecting, handling, storing, and getting rid of radioactive material must be done in accordance with TB

MED-232 and TB 750-237.

When placing the turret (elev/trav) power switch in the ON position, ensure that the gunner's power control

handles are not displaced. If handles are displaced, rapid movements of the turret traverse in azimuth may

result in fatal injury.

When turret is in the power mode the gun will elevate and depress without depressing the magnetic brake

switch on the gunner's control handles.

Assure crew are in safe positions and driver has lowered his seat and has head down before operating in

power or manual traversing or elevating modes.

Do not release magnetic brake switch or override in magnetic brake actuator while traversing until gunner's

or commander's power control is returned to neutral position. This will reduce unnecessary wear and/or

damage to magnetic brake.
