BREAK-IN OPERATION
a.
Road Test.
CAUTION
Do not go faster than the maximum allowable speeds shown on the maximum road speed data plate. Do
not drive continuously at maximum allowable speeds. Be alert for signs of equipment failure. Failure to
do this may result in equipment damage.
All vehicles received by the using organization must be road-tested to check operation and condition of all
reconditioned vehicles, except those previously driven 50 mi (80 km). The operator will check the instrument panel and
gauges as often as possible for signs of unsatisfactory performance. Stops will be made at least every 10 mi (16 km) to
give the operator a chance to check the vehicle for possible coolant, oil, fuel, or exhaust leakage and any signs that may
show the engine, transmission, wheel hubs, brake drums, axles, differentials, or transfer case assemblies are overheated.
The vehicle must be checked thoroughly for any control that is hard to operate and any instrument not operating properly.
Unusual noises and vibration will be noted. All unusual conditions will be reported to unit level maintenance.
b.
After Road Test. After the road test, correct any faulty condition that can be done at operator’s maintenance
level. Notify unit maintenance about any other faulty condition.
