Section IV. TEST AND ADJUSTMENTS
7-80. General
a.
This section contains the test and adjustment
procedures that are required to be performed on a rebuilt
or repaired engine. These tests must be performed with
engine installed on semitrailer, and with batteries, control
boxes, fuel supply filters, and electrical supply hooked up
to the engine.
WARNING
Carbon monoxide is a colorless, odorless,
and deadly poisonous gas which occurs in
the exhaust fumes of the auxillary power en-
gine. Exposure to air contaminated with car-
bon monoxide produces symptoms of
headache, dizziness, loss of muscular con-
trol, apparent drowsiness, and coma. Perma-
nent brain damage or death can result from
severe exposure to carbon monoxide gas.
b.
Engine must be properly vented to exhaust the
engine to outside air. If possible, avoid sharp bends in
exhaust pipe or use sweeping, large radius elbows. Use a
section of seamless, flexible tubing between the engine
and any rigid pipe to restrict vibration. Increase exhaust
pipe one size larger for each additional 10 feet of length.
c.
For engine operating instructions, refer to
paragraph 2-10.
