Ether±and±Engines
The engines in PLS trucks have built-in ether
starting aids. They use measured amounts of ether
to help start your trucks in very cold weather. Use
only the approved procedures shown in the TM for
ether usage. External spray cans of ether
are not
authorized
for use on any PLS trucks.
If you think it’s no big deal to spray the ether
anyway, maybe this will change your mind. Ether
has a higher and hotter rate of burn than JP8 and
diesel. Spraying external ether can damage your
PLS truck’s engine, causing your vehicle to stop
instead of start!
Spraying ether into engines will crack pistons,
fracture cylinder sleeves, bend connecting rods
and ruin engine cylinder heads. This can lead to
permanent damage and your vehicle will be NMC.
That’s
not
what you want.
So remember, whenever your PLS truck won’t start, do this:
•±
Follow the troubleshooting guidance in the Operator’s TM.
•±
If that doesn’t help, call your mechanic to find out what’s wrong.
Don’t
use
spray can
ether!
