here’s danger related to your unit’s M1074A1 and M1075A1 PLS charge air cooler
and radiator assembly doors. While working inside the engine compartment or in
the path of the door frame, you could be struck or crushed against the engine or
vehicle fender!
The charge air cooler and radiator assembly doors are two-piece assemblies; they
have a guard and a frame assembly. The outer guard on each door can be held open
with a prop rod while maintenance is done inside the engine compartment.
The outer door guards
also
have
a
latch
that
allows the two pieces to be
separated from the radiator
and charge air cooler frame
assemblies. If the latch
is pulled while the prop
rod is in use, the frame
separates from the guard.
The frame will move and
can strike or crush anyone
working inside the engine
compartment or in the path
of the frame.
