WARNINGS
For 2" trailer balls
Capacity: 3,500 lbs.
Tongue weight: 500lbs.
Read instructions carefully before installation or operation.
Failure to follow these warnings and installation instructions
will result in separation of tow vehicle and trailer, which can
result in death, personal injury and property damage.
Always note proper installation of underjaw; notch in
underjaw should engage coupler body cross shaft at
all times. Failure to do so could result in coupler failure.
INSTALLATION
Step 1
Place the handle in the locked position with a trailer ball
in the coupler. Insert the handle (#1) through the latch hole
in the coupler. Place the release spring (#2) on the handle,
on the underside of the coupler.
Step 2
Attach the underjaw (#3) to the handle and release spring.
See figure 2. Note: The notch in underjaw should engage
the coupler body cross shaft. See figure 3.
Step 3
Tighten locknut (#6) against the square washer (#4) and
tension spring (#5) underneath the underjaw so that the
coupler is not loose on the ball. See figure 2. Correct
adjustment will allow handle to be released with moderate
pressure applied to the release latch.
Step 4
After towing 50 miles, check the tightness of the coupler
on the ball. Be sure latch handle is in the locked position.
