INSPECTION / MAINTENANCE / OPERATION
Inspection and Maintenance
:
1. Visually inspect the coupling body and latch
components for cracks, impact damage and/
or deformation before each and every use. Do
NOT use if any of these conditions exist.
2. Check the gap between the top of the 892
Hook and the nearest adjacent surface of the
coupling body before each and every use.
Pull the hook out, away from the coupling,
to remove any free play in the coupling and
measure the gap. A gap of 3/8” or more means
the coupling must be taken out of service and
repaired or replaced.
3. If the wear area on the 892 Hook has worn
20% or more from its original cross-section, the
coupling is considered out-of-service and must
NOT be used.
4. Lubrication of the latch components must
be performed at 90-day intervals or sooner
depending on the operating environment.
Lubricate the latch components with a spray-
type lubricant to evenly coat all rotation points.
Rotate each latch component several times to
evenly distribute the lubricant.
5. Do not apply lubricant anywhere on the 892
Hook except for in its bolt hole. Remove any
excess lubricant with a rag.
6. Never weld on any Premier part in order to
repair damaged or worn areas. Field and/or
shop welds are inadequate and may further
weaken the coupling.
7. WARNING: Other inspection and maintenance
procedures are also required prior to the
operation of combination vehicles. Consult
and follow all Federal Motor Carrier Safety
Regulations as well as local, state and federal
guidelines.
Operation
:
OPENING Coupling Latch:
(See specific model of
coupling for proper opening instructions)
890CL
:
1. Remove the 891P Pin from the 891 Handle.
2. Grasp the 896 Handle and rotate it downward
(clockwise) until it stops and hold it there.
3. Rotate the 891 Handle clockwise until full
rotational travel is reached. Next, release the
smaller 896 Handle and then release the 891
Handle.
4. If opening the coupling with a drawbar eye
attached, the coupling is now ready to uncouple
and the drawbar eye should pull freely from the
892 Hook.
5. If opening the coupling without a drawbar eye
being coupled to it, follow the above steps 1-3.
The 892 Hook should freely rotate down, but is
NOT in the fully open position. Next, grasp the
top of the 892 Hook and pull out and down until
full rotational travel is reached. The coupling’s
latching mechanism will snap into the fully open
position.
6. The 890CL Coupling is now fully open and
ready to be coupled.
890CR
:
1. Remove the 891P Pin from the 891 Handle.
2. Grasp the 896 Handle and rotate it downward
(counter-clockwise) until it stops and hold it
there.
3. Rotate the 891 Handle counter-clockwise until
full rotational travel is reached. Next, release
the smaller 896 Handle and then release the
891 Handle.
4. If opening the coupling with a drawbar eye
attached, the coupling is now ready to uncouple
and the drawbar eye should pull freely from the
892 Hook.
5. If opening the coupling without a drawbar eye
being coupled to it, follow the above steps 1-3.
The 892 Hook should freely rotate down, but is
NOT in the fully open position. Next, grasp the
top of the 892 Hook and pull out and down until
full rotational travel is reached. The coupling’s
latching mechanism will snap into the fully open
position.
6. The 890CR Coupling is now fully open and
ready to be coupled.
