Operation
:
OPENING Coupling Latch:
1. Remove the 154 Latch Pin from the 152 Latch
by firmly grasping the ringlet on the latch pin
and pull outward.
2. Once the 154 Latch Pin has been removed,
grasp the 152 Latch and squeeze the 151
Trigger.
3. While holding the 151 Trigger, rotate the
entire latch assembly a full 90° in either
direction and release the trigger.
4. The 160HD Coupling is now open and ready to
couple or uncouple.
CLOSING Coupling Latch:
5. Rotate the 152 Latch until its nose is directly
over the center of the pintle/hook. The 151
Trigger should snap into the notch on the
coupling body.
6. Verify the 160HD Coupling has been securely
closed by grasping the 152 Latch and
attempting to rotate it in either direction. If the
latch moves and does not remain locked in
position, perform the following:
a: Look for debris in the notch on the 160HD
Coupling body that could prevent the
151 Trigger from fully seating. If debris
is found, clean the notch and try latching
again.
b: Grasp and squeeze the 151 Trigger
repeatedly to verify free motion. If the
trigger is frozen in place or non-responsive,
lubricate the trigger around the 153B Roll
Pin with a light penetrating oil. Squeeze
the trigger several times to evenly
distribute the lubricant.
c: If neither of these actions succeeded
in correcting the latching problem, the
coupling is considered out-of-service
and must NOT be used. There may be
unrepairable damage to either the latch
assembly or coupling body.
7. Once verified that the coupling is securely
closed, lock the 152 Latch in the closed
position with the 154 Latch Pin. Slide the pin
all the way through the bottom hole in the
latch (NOT the 153B Roll Pin hole) until the
ringlet on the pin prevents it from passing
through further. If the pin will not pass all the
way through to the ringlet, the 151 Trigger
is NOT fully seated and step 6 must be
repeated. The latch pin must be properly in
place before the coupling may be used.
8. Verify that the 154 Latch Pin has secured
the latch by attempting to squeeze the 151
Trigger and then rotating the 152 Latch to the
open position. THE LATCH SHOULD NOT
OPEN! If the latch can be opened with the
latch pin in place, the coupling is considered
out-of-service and must NOT be used. Closer
inspection is needed to determine which
part(s) is damaged that allows the latch to
open. Replace the affected parts and repeat
steps 5-8.
9. This product is designed to be operated within
its free rotation limits. It is the responsibility
6. Remove any excess lubricant with a rag. Do
not apply lubricant to the pintle/hook or saddle
area of the coupling.
7. 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.
8. 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.
