ORGANIZATIONAL PREVENTIVE MAINTENANCE CHECKS AND SERVICES.
|
To insure that the mixer body is ready for operation at all times, it must be inspected systematically so that defects may be
discovered and corrected before they result in serious damage or failure.
Table 3-1 contains a tabulated listing of
preventive maintenance checks and services to be performed by organizational maintenance personnel.
All deficiencies
and shortcomings will be recorded, as well as, the corrective action taken on DA Form 2404 at the earliest possible
opportunity.
a.
The item numbers of Table 3-1 indicate the sequence of the PMCS.
Perform at the intervals shown below:
(1)
Do your (Q) PREVENTIVE MAINTENANCE once each 3 months.
(2)
Do your (S) PREVENTIVE MAINTENANCE twice a year, or each 6 months.
(3)
Do your (A) PREVENTIVE MAINTENANCE once each year.
(4)
Do your (B) PREVENTIVE MAINTENANCE once each two years.
(5)
Do your (H) PREVENTIVE MAINTENANCE at the hour interval listed.
(6)
Do your (MI) PREVENTIVE MAINTENANCE when the mileage of the vehicle reaches the amount listed.
b.
If something doesn’t work, troubleshoot it with the instructions in this manual or notify your supervisor.
c.
Always do your preventive maintenance in the same order, so it gets to be a habit.
Once you’ve had some
practice, you’ll spot anything wrong in a hurry.
d.
If anything looks wrong and you can’t fix it, write it down on your DA Form 2404.
If you find something
seriously wrong, report it to direct support as soon as possible.
WARNING
Dry cleaning solvent SD-2, used to clean parts, is potentially dangerous to personnel and
property.
Do not use near open flame or excessive heat.
Flash point of solvent is 1380F.
(1)
Keep it clean:
Dirt, grease, oil, and debris only get in the way and may cover up a serious problem.
Clean as you work and as needed.
Use dry cleaning solvent (SD-2) to clean metal surfaces.
Use
soap and water when you clean rubber or plastic material.
(2)
Bolts, nuts, and screws
: Check that they are not loose, missing, bent, or broken.
You can’t try them all
with a tool, of course, but look for chipped paint, bare metal, or rust around bolt heads.
Tighten any that you find loose.
(3)
Welds
: Look for loose or chipped paint, rust, or gaps where parts are welded together.
If you find a bad
weld, report it to direct support.
