•
Keep the front engine compartment
doors shut when you run the A/C. If
they’re left open, the A/C can overheat
and blow fuses.
•
Check that the sampling box slides
out. If the box won’t slide, clean and lube
the tracks it moves on. Use a light lube
like WD-40. Make sure the tongs are
chained to the box or they will disappear
in the Feld.
•
Keep the material access port open
when the ±ox is sitting. That lets fresh
air in the rear compartment. If the ±ox
sits sealed, it becomes a mildew jungle.
Corrosion,
electrical
problems,
and
computer faults result.
•
Check the cords for the handset in the
rear for signs of dry rot. The handset is
the main form of communication to the
outside. If the cords short out, you’ve
got problems. Report dry rot.
•
All the hatches, windows, and doors
have levers held on by bolts. The bolts
work loose over time and can come out
completely. Then the lever comes off.
Check the bolts quarterly for tightness.
•
When you’re training at night, check
the night vision devices. You can’t
check them during your daily PMCS
because of sunlight, so night is your only
opportunity to make sure they work.
•
If you have to remove the belly plate,
Frst pull out the hydraulic system fuse.
If you don’t, you could damage the
electronic hydraulic pump.
