ST-70 — TOWING INFORMATION
1. Position actuator ball socket above 2" ball.
WARNING: Use jack stand to lift tongue. Do NOT lift by
hand as back injury could result.
CAUTION:
The ball capacity must be greater than or equal
to the trailer GVWR. Do not use a worn hitch
ball, it is unsafe and must be replaced. USE 2"
BALL ONLY
NOTE:
Take care not to damage the actuator when backing up the
towing vehicle for hook-up.
2. Hold the release handle in the open position (Figure 1).
3. Lower the trailer tongue until the ball rests in the ball socket.
4. Close the release handle.
CAUTION:
The release handle will close freely with
finger pressure when the ball is properly
inserted into ball socket. If the release handle
does not close freely, do not tow the trailer. Do
not force the release handle into the closed
position.
5. To make sure that the actuator is securely latched onto the
ball, extend the trailer tongue jack to the ground and lift the
truck and trailer combination 2" to 4". If the ball does not
disengage, the actuator is securely attached.
6. Insert a padlock or bolt through the lock hole for added
protection.
7. Connect the breakaway cable solidly to the bumper or frame
of the tow vehicle as near to the center as possible. The
cable must hang clear of the trailer tongue and be long
enough to permit short radius turns without pulling the
breakaway cable forward.
8. Make sure the breakaway cable is in a released position
with the indicator bead touching or resting against the cable
spring stop. (Figure 2).
CAUTION:
Do not use the breakaway cable as a parking
brake.
NOTE:
Check the location of the breakaway cable periodically
during each trip. The indicator should rest against the spring
stop. Accidental application will cause the brakes to drag
and heat up, causing a failure.
9. Cross the safety chains under the tongue and securely
attach them to the bumper or frame of the tow vehicle. Check
with local and state laws for proper compliance.
CAUTION:
Safety chains must always be used.
