d.

Scrape, sand, prime, and repaint areas

where finish is missing or where there is evi-
dence of corrosion.

e.

Replace any missing or illegible decals. Re-

place any missing or damaged reflective tape.

f.

Use Troubleshooting Guide to check for

“SYMPTOMS” AND “PROBLEMS” of any
semitrailer system not functioning correctly, or
where wear, distortion, or breakage can be
found. Administer “REMEDY” according to
right-hand column of Troubleshooting guide.

g.

After disassembling any components, thor-

oughly clean dirt and old lubricant from all
parts. Do not use a wire brush on any bearing
parts or surfaces — use a stiff bristle brush.
Do not use compressed air, or spin bearing
parts when cleaning. These practices can
throw solvents, dirt, or metal particles into
your eyes. Dry clean parts with lint free,
clean, soft, absorbent, cloth or paper. Wash
and dry hands.

h.

Inspect seals, seal wiping surfaces, bearing

caps, and bearing cones for wear, pitting,
chipping, or other damage.

GOOSENECK, FRAME, AND DECK

4-3.1

Repairing Structural Defects

If any structural defect is found, the fault must

be corrected before further use of the vehicle. To
continue usage could endanger the trailer, its load,
personnel, traffic, and properties. If any cracks or
breaks are found, contact the Landoll factory for
repairs. Inspect the deck daily for broken or miss-
ing planks or missing attachments. Replace any
defective parts promptly.

HYDRAULIC SYSTEM

4-4.1

General

a.

Check the hydraulic oil level weekly, or after

any leakage. See

Table 4-1

for proper hy-

draulic oil. Check the hydraulic oil level with
hydraulic cylinders in the retracted position
and the hydraulic pump disengaged. Enough
volume in tank (approximately 15 gallons)
above hydraulic oil level must be available to
accept extra oil from cylinders when retracted.

b.

Overfilling can cause hydraulic fluid over-

flow during operation.

c.

Hydraulic system pressure relief valves

should be set at 2500 psi.

d.

Check hoses weekly for cracks or leaks. If a

valve or line leaks, it should be replaced im-
mediately.
