GENERAL
a. These general maintenance instructions contain general shop practices and specific methods you must be familiar
with to properly maintain your M9 ACE.
You should read and understand these practices and methods before
performing any general support maintenance tasks.
b. Before beginning a task, find out how much repair, modification, or replacement is needed to fix the equipment as
described in this manual.
Sometimes the reason for equipment failure can be seen right away, and complete
teardown is not necessary.
Disassemble equipment only as far as necessary to repair or replace damaged or broken
parts.
c. The following "Initial Setup" information applies to all procedures:
(1) Resources are not listed unless they apply to the procedure.
(2) Personnel are listed only if more than one technician is required to complete task.
If "Personnel Required" is
not listed, one technician can complete task.
d. All tags and forms attached to equipment must be checked to learn the reason for removal from service.
Modification
Work Orders (MWOs) and Technical Bulletins (TBs) must also be checked for equipment changes and updates.
e. In some cases, a part may be damaged by removal.
If the part appears to be good and other parts behind it are not
defective, leave it on and continue with the procedure.
Here are a few simple rules:
(1) Do not remove dowel pins or studs unless loose, bent, broken, or otherwise damaged.
(2) Do not remove bearings or bushings unless damaged.
If you need to remove them to access parts behind them,
pull bearings and bushings out carefully.
(3) Replace all gaskets, seals, and preformed packings.
WORK SAFETY
a. Observe all WARNINGs and CAUTIONs.
Always use power tools carefully.
b. Protect yourself against injury.
Wear protective gear, such as safety goggles or lenses, safety shoes, rubber apron,
or gloves.
c. When lifting heavy parts, have someone help you.
Make sure that lifting/jacking equipment is working properly, is
suitable for assigned the task, and is secure against slipping.
