MAINTENANCE AND LUBRICATION
This section contains instructions necessary for
proper maintenance of the semitrailer. The
825A/835 semitrailer is designed for years of serv-
ice with minimal maintenance. However, proper
maintenance is important for durability and safe
operation and is an owner/user responsibility.
4-1 MAINTENANCE SCHEDULE
Trailer maintenance includes periodic inspec-
tion and lubrication.
Table 4-2, Maintenance
Schedule
, lists the recommended maintenance
and lubrication tasks by time interval and by accu-
mulated mileage (use whichever occurs first).
DANGER
OPERATING THE TRACTOR OR
TRAILER WITH DEFECTIVE, BROKEN
OR MISSING PARTS MAY RESULT IN
SERIOUS INJURY OR DEATH, DAM-
AGE TO THE TRACTOR/TRAILER, ITS
CARGO, OR PROPERTY IN ITS PATH.
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
detail lubrication
points and intervals, method of application, and lu-
bricant required, and illustrate the location of each
part to be lubricated. During inspections 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.
WARNING
PAINT THINNER AND OTHER SOL-
VENTS ARE FLAMMABLE AND TOXIC
TO EYES, THE SKIN, AND RESPIRA-
TORY TRACT. AVOID SKIN AND EYE
CONTACT. GOOD GENERAL VENTILA-
TION IS NORMALLY ADEQUATE. KEEP
AWAY FROM OPEN FLAMES OR
OTHER COMBUSTIBLE ITEMS.
