IMPORTANT
TO CHECK THE TENSION ON THE LATCH,
PLACE A PRY BAR BETWEEN THE FIFTH
WHEEL PLATE AND THE BACKING PLATE
AND
PRY
DOWN
UNTIL
THE
LATCH
RE-
LEASES.
IF
IT
RELEASES
TOO
EASILY,
TIGHTEN THE SPRING TENSION. IF YOU ARE
UNABLE TO TRIP IT, BACK OFF THE SPRING
TENSION UNTIL YOU ARE ABLE TO TRIP THE
RELEASE.

HYDRAULIC SYSTEM
4-4.1
General
a.
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. Enough
volume in tank (approximately 15 gallons)
above hydraulic oil level must be available to
accept extra oil from telescopic cylinder when
retracted.
b.
Overfilling can cause hydraulic fluid overflow
during operation.
c.
Dock leveler flow bypass regulator must
provide 2.5 to 3.0 gallon per minute to dock
leveler valve for Single Pair Dock Leveler
(62,000 lb.). Dock leveler flow bypass regula-
tor must provide 6.0 gallon per minute to dock
leveler valve for Double Pair Dock Leveler
(124,000 lb.).
d.
Hydraulic system pressure relief valves
should be set at 2500 psi.
4-4.2
Hydraulic Engine Package
a.
Check the hydraulic oil level weekly, or after
any leakage. See
Table 4-1
for proper hy-
draulic oil. Check oil level with the undercar-
riage telescopic cylinder extended and all
other hydraulic cylinders in the retracted posi-
tion and with the engine stopped.
b.
Check hoses weekly for cracks or leaks. If a
valve or line leaks, it should be replaced im-
mediately.
c.
Check the engine oil each time before us-
ing. Oil level should be maintained between
the “L” and “F” marks on the oil dip stick. For
further maintenance procedures and proper
lubrication specifications, please refer to the
engine owners manual that was supplied with
the hydraulic engine package.
d.
Replace hydraulic filter with new filter
(See
Table 4-2).
e.
Use the fuel recommended for the engine
package installed on your semitrailer.
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.
