SECTION IV.
LEAD FILTER SYSTEM
14-14. GENERAL
The lead filter system is designed for the removal of contaminants, primarily lead contaminants, that are present in the
propellent fumes generated when the cannon is fired.
Failure of the lead filter system will allow fumes to enter the crew
cab, thereby, causing the crewmembers to breathe the toxic fumes.
BDAR action of the lead filter system is limited to the
accessory control box.
14-15. ACCESSORY CONTROL BOX
General Information:
The accessory control box contains a circuit breaker and the ventilation fan selector switch which applies power to the lead
filter fan, when in the UP position.
The only BDAR fix for the lead filter system is to replace the circuit breaker and/or the
ventilation fan selector switch when they are damaged or when they malfunction.
For BDAR fix of the ventilation fan selector switch, see Chapter 3, para 3-15 "Switches Damaged".
For BDAR fix of the circuit breaker, see Chapter 3, para 3-16 "Circuit Breakers Damaged".
