ST-45 — TOWING INFORMATION
1. Position actuator ball socket above 2" ball.
2. Hold the release lever in the open position (Figure 39).
3. Lower the trailer tongue until the ball rests in the ball socket.
4. Close the release lever.
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 break-away 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 40).
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
Use jack stand to lift tongue. DO NOT lift by
hand as back injury could result.
Towing Information
WARNING
Take care not to damage the actuator
when backing up the towing vehicle
for hook-up.
NOTE
The release lever will close freely with finger
pressure when the ball is properly inserted
into ball socket. If the release lever does not
close freely, do not tow the pump. DO NOT
force the release handle into the closed
position.
CAUTION
DO NOT use the breakaway cable as a
parking brake.
CAUTION
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.
NOTE
