Section III. Operator Troubleshooting.
APPROVED HEARING PROTECTION MUST BE WORN by operator and any personnel within
22 ft. (7 m) of an IHMEE at high idle or within 12 ft. (4 m) of an IHMEE at low idle. Personnel
hearing can be PERMANENTLY DAMAGED if exposed to constant high noise levels of 85 dB (A)
or greater. Personnel exposed to high noise levels shall participate in a hearing conservation program
in accordance with DA PAM 40-501. Hearing loss occurs gradually but becomes permanent over time.
Failure to comply may cause impairment or loss of hearing.
Table 3-3 lists common malfunctions that you may find with IHMEE. To quickly find a troubleshooting procedure, use the
Fault Symptom Index (Table 3-3). Table 3-4 is the Troubleshooting Table, which contains the operator troubleshooting steps.
Before using troubleshooting tables, be sure all applicable Preventive Maintenance Checks and Services (PMCS) have been
performed. Perform tests, inspections, and corrective actions in the order listed. Try to return the vehicle or component to
operation after each test, inspection, and corrective action has been performed.
Perform the tests, inspections, and corrective actions in the order they appear in the table. This manual cannot list all
malfunctions that may occur, nor all tests or inspections and corrective actions. If a malfunction is not listed or is not
corrected by listed corrective actions, notify the supervisor.
While doing troubleshooting, refer to any figures, procedures, and publications mentioned in the text. This information will
help isolate and locate troubles and get the vehicle back in service as quickly as possible.
