One is Not Enough!
Dear Sergeant D. L. A.,
You are right! Both generators must be mission capable at all times.
Hear me all troops using the RAID system! Your system may have two 5-kW
generators or two 15-kW generators. Both must be in working condition. If
one is not,
immediately contact your feld service representative (FSR) ±or
the RAID system.
If you need help Fnding that representative, call DSN 318-
847-2423 or email:
RAID_helpdesk@mnd-b.army.smil.mil
The grapevine has been singing to me that too many of you are sticking
the inoperative generator in a corner and forgetting about it. Then, you’re
running one generator 24/7. Stop doing that!
Also, start doing preventive maintenance. Here are the technical manuals
for the 5-kW generators: TM 9-6115-641-10; TM 9-6115-641-24; TM 9-
2815-252-24; and LO 9-6115-641-12. And for the 15-kW generators: TM 9-
6115-643-10; TM 9-6115-643-24; TM 9-2815-254-24; and LO 9-6115-643-
12. These manuals will get you on track for doing regular lubes; inspecting
the oil, fuel, and battery electrolyte levels; checking all the Flters and cables;
and knowing when to, and how to, purge the fuel-water separator.
One Fnal word on generator maintenance: be alert to wetstacking!
Wetstacking happens when unburned fuel passes directly into the exhaust
system. The cause of wetstacking is running your generator at too low of a
load for too long of a time.
If you notice a wetstacking problem, load your generator up to at least 80
percent of its capacity. You can do this by operating your air-conditioning
unit or heater. Run the generator for at least an hour or until the engine
starts running smoother and the exhaust port is no longer wet.

Dear Half-Mast,
We have two 5-kW generators as part of our rapid aerostat initial
deployment (RAID) system. Each generator is supposed to run 12-hours
on and 12-hours off. Unfortunately, one of our generators is down for
maintenance and we’re running one generator all the time! I think this
defeats the purpose of the RAID system. What do you think?

is a part to
do my part!
