o Keep the hull floor clean. Dust, dirt, sand and
debris can build up and hide fuel spills and leaks.
Then you’ve got a fire just waiting for a spark.
o Clean the fire sensors daily in the field. They
can’t detect a fire if they’re dirty. Use lens cleaner,
NSN 6850-00-227-1887, and lens tissue, NSN
6640-00-436-5000, to prevent scratching the lens.
o Report all fuel leaks as soon as you spot them, no
matter how small. Fuel filters, PTS actuator hoses,
and smoke generator lines are good places to look
for leaks.
Give the combustor fuel nozzle,
line and fittings special attention
when the pack is pulled. The nozzle
should be securely mounted and
torqued to 90-100 lb-in. Any less
could allow a leak. Make sure you
bend the tabs of key washers against
the bolt heads, too.
o Look for damage to the combustor
heat shield if your vehicle has one.
Make sure the shield is securely
mounted to the engine.
o Eyeball all electrical cables for
wear and damage from rubbing on
sharp metal edges. Sparks from arc-
ing or shorting starts most fires. The
most commonly damaged cables are:
—The cables routed through the opening between the battery box and the
engine compartment.
—The cables routed along the top edge of the powerpack.
—The cables that run along the outside edge of the generator.
—The generator’s cable harnesses and terminals.

it starts.
After all, your
