MAINTENANCE AND LUBRICATION
Hitch, Frame, and Deck
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 a Landoll authorized service center for repairs.
Inspect the deck daily for broken or missing planks or
missing attachments. Replace any defective parts
promptly.
Hydraulic System
General
1. 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.
2. Overfilling can cause hydraulic fluid overflow during
operation.
3. Check the lubricating oil level in the engine of the
hydraulic engine power option.
4. Inspect hydraulic hoses for chafing or damage.
Replace if jacket or braid of hose is damaged.
5. Replace hydraulic engine power filter as specified in
Table 4-2.
Electrical System
1. Maintenance of the electrical system consists of
inspection and minor servicing. Any wire, connection
or electrical component showing signs of corrosion,
wear, breakage or unraveling must be repaired or
replaced.
2. Frayed or unraveling wire must have the defective
section removed and replaced with wire of the same
color and gauge. Seal all connections and insulate.
3. Corroded terminals must have the corrosion
removed, source of corrosion neutralized and the
terminals resealed, protected, and insulated.
4. Fuse or circuit breaker burn-out or blow-out usually
indicates an electrical short-circuit, although a fuse
can occasionally fail from vibration. Insert a second
fuse or reset the breaker. If this fuse immediately
burns out or the breaker trips, locate the cause of the
electrical short and repair.
5. A light that repeatedly burns-out usually indicates a
loose connection, poor system ground, or a
malfunctioning voltage regulator. Locate the source
of the problem and repair. System grounds must be
grounded to bare metal surfaces. Paint, grease, wax,
and other coatings act as insulators. Replacement
lamps must be equivalent to the factory installed
lamp.
