MAINTENANCE AND LUBRICATION
This section contains instructions necessary for
proper maintenance of the semitrailer. The 900B
Series semitrailer is designed for years of service
with minimal maintenance. However, proper main-
tenance is important for durability and safe opera-
tion and is an owner/user responsibility.

DANGER
O P E R A T I N G T H E T R A C T O R O R
TRAILER WITH DEFECTIVE, BROKEN
OR MISSING PARTS MAY RESULT IN
SERIOUS INJURY OR DEATH, DAM-
AGE TO THE TRACTOR/TRAILER, ITS

4-1.1
Inspection
a.
Inspect the tractor, the trailer, and trailer
parts periodically for damage or signs of
pending failure. Damaged or broken parts
must be repaired or replaced at once. Deter-
mine the cause of any binding or hydraulic
leakage at once. Correct the problem before
using the tractor or trailer.
b.
Use the troubleshooting section, Chapter 5
to check for “SYMPTOMS” and “PROBLEMS”
of any trailer system not functioning correctly,
or where wear, distortion, or breakage are
found. Administer “REMEDY” according to
the right-hand column of the troubleshooting
section.
4-1.2
Lubrication
Figures 4-1 and 4-2 and Table 4-1
detail lu-
brication points and intervals, method of applica-
tion, and lubricant required, and illustrate the loca-
tion of each part to be lubricated. During inspec-
tions of the trailer, if lubricants are found to be
fouled with dirt or sand, those parts should be
cleaned with paint thinner, dried, and relubricated
immediately. Dirt in a lubricant forms an abrasive
compound that will wear parts rapidly.
