Troubleshooting

Fuse
The Power Stance Tongue Jack is provided with a 30A ATO-type in-line fuse which will need to be replaced if it blows. The battery must be fully charged prior to operating the Power Stance Tongue Jack. Low voltage from the battery will cause the fuse to blow prematurely.
NOTE : When RET or EXT on the switch is pushed, the light above the switch will turn on automatically, and remain on for five minutes. It will then automatically turn off.

Clutch
The Power Stance Tongue Jack is provided with a clutch and a motor. The clutch will slip under two conditions:

The Power Stance Tongue Jack has reached its extend or retract limit.
The tongue weight of the trailer has exceeded the capacity limits of the PowerStance Tongue Jack. Items stored in the trailer can vastly influence the weight on the PowerStance Tongue Jack. Reorganize stored items if the PowerStance Tongue Jack motor clutch continues to slip.

NOTE: Release the switch immediately when the clutch noise occurs. The clutch is the overload protection for the motor. The clutch should not slip during normal operation. This will cause excessive wear on the clutch and the motor.
