Scrape, sand, prime, and repaint areas

where finish is missing or where there is evi-

dence of corrosion.

Replace any missing or illegible decals. Re-

place any missing or damaged reflective tape.

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.

Inspect seals, seal wiping surfaces, bearing

caps, and bearing cones for wear, pitting,

chipping, or other damage.

4-3 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.

4-4 HYDRAULIC SYSTEM

4-4.1

General

Check the oil level of the tractor wet kit or

hydraulic engine power hydraulic tank weekly,

or after any leakage. See

Table 4-1

for proper

hydraulic oil. Check the hydraulic oil level with

hydraulic cylinders in the retracted position

and the hydraulic pump disengaged.

Overfilling can cause hydraulic fluid overflow

during operation.

Dock leveler flow bypass regulator must

provide 2.2 to 2.8 gallon per minute to dock

leveler valve.

Hydraulic system pressure relief valves

should be set at 2500 psi.

WARNING

IF MORE OIL THAN SPECIFIED IS

SENT TO DOCK LEVELER VALVE,

DAMAGE TO DOCK LEVELERS AND

PERSONAL INJURY CAN OCCUR. IT

LESS OIL THAN SPECIFIED IS SENT

TO DOCK LEVELER, THEY WILL NOT

OPERATE OR OPERATION WILL BE

ERRATIC.
