WORK SAFETY 0009 00
1. Before starting a task, think about the risks and hazards to your safety as well as that of others. Wear protective gear
such as safety goggles or lenses, safety shoes, rubber apron, or gloves. Protect yourself against injury.
2. Observe all WARNINGs, CAUTIONs, and NOTEs.
GENERAL INFORMATION 0009 00
1. Before beginning a task, find out how much repair, modification, or replacement is needed to repair the weapon as
described in this manual. Sometimes the reason for equipment failure can be seen right away and complete teardown is
not necessary. Disassemble the weapon only as far as necessary to repair or replace damaged or broken parts.
2. All tags and forms attached to the equipment must be checked to learn the reason for removal from service. Check all
Modification Instructions (MIs) and Technical Bulletins (TBs) for equipment changes and updates.
3. In some cases a part may be damaged by removal. If the part appears to be good, and other parts behind it are not defec-
tive, leave it on and continue the procedure.
