COUPLER ASSEMBLY (SN 0030002099 TO
PRESENT)
Engaging Manual Lockout Lever
The manual lockout lever is used to control the brake pressure
being applied to the trailer when backing up. Having the actu-
ator in the extended position will make it easier to engage the
lockout lever. To engage the lockout lever, move the lever back
and upwards until the front of the lever nests into the round
spacer as shown below. This will prohibit movement of the
actuator when backing up. The lockout lever will move to the
towing position when you drive forward again.
Servicing the Breakaway Assembly
A thorough inspection of the breakaway assembly is required
if it is applied at any time. Damaged parts must be replaced. If
there is any damage to the lanyard itself the entire pushrod
assembly will need to be replaced.
To disengage the breakaway mechanism, first release the
brake line pressure by briefly opening a bleeder valve. Extend
the coupler forward to gain access to the 1/2" hole on the top
of the coupler housing as shown below.
Insert a flat head screwdriver into the access hole and push
down on the pushrod assembly and pivot the pushrod
towards the front of the coupler. Make sure the pushrod
assembly is moved to its furthermost forward position
(towards the front of the coupler) by pushing down and for-
ward on the rod. Inspect and replace parts as needed.
NOTE:
The end of the pushrod should line up with the front of the
1/2" access hole.
