BREAKING-IN PERIOD
The pride of ownership, trouble-free performance and maximum life and
enjoyment you receive from your Hudson Terraplane car depends largely on the
manner in which your car is operated during the "breaking-in-period" or the first
thousand miles of driving.
Your car has been designed by capable engineers, in accordance with the best
practices determined by years of experience, built under the most rigid standards
of precision, and rigidly inspected throughout its manufacture to insure proper
clearances being maintained.
Before shipment from our factory the car was thoroughly lubricated to insure
proper lubrication to the finely finished parts. The lubricants used are of the
highest quality obtainable and have been selected only after being subjected to
laboratory test.
Failure to follow accepted practice, as described in the following paragraphs,
may result in damage to bearing surfaces, cylinder walls or pistons, or abnormal
increases in clearances, which will shorten the life and impair the performance of
the various units.
Be sure that the proper radiator water level is maintained at all times. Check
engine oil level frequently to insure sufficient lubrication.
Accelerate gently, as fast acceleration places heavy loads on the working
parts. Use second gear under adverse conditions. Never attempt to take a grade
in high for the mere sake of demonstrating power.
Careful application of brakes during the break-in period is also essential, as
brake linings and drums require proper run-in. Harsh braking in early life may
cause scored linings and drums as well as placing heavy loads on the driving
members.
Adhering to the following speed table will insure proper run-in of all units of
the car:
0-250 MILES
Do not exceed 40 miles per hour in high gear or 20 miles per hour in sec-
ond. Do not accelerate rapidly. Use second gear on steep grades.
250-500 MILES
Do not exceed 50 miles per hour in high gear or 25 miles per hour in second.
500-1000 MILES
During this period the speed should not exceed 60 miles per hour.
