Slider Repositioning
Operation
WARNING
Before you operate a vehicle equipped with a sliding trailer
suspension, lock the sliding suspension securely and position
it correctly. Loss of vehicle control, serious personal injury and
damage to components can result when the sliding
suspension is not locked securely and positioned correctly.
The RideSentry™ MPA Series sliding tandem trailer air suspension
system must be securely locked prior to operation. The suspension
is locked when the main body of each lock pin extends through the
holes in the rails. Before pulling the trailer, carefully inspect the
suspension to ensure that it is correctly positioned and the main
body of each lock pin extends through the holes in the rails. Apply
the trailer brakes and gently rock the trailer backward and forward
to ensure that the suspension is secure.
To Correctly Reposition the Sliding Suspension
1.
Set both the tractor and trailer brakes. Remove the locator stop
bar, if the option is available, from behind the slider. Move it to
the desired location.
2.
Release the lock pins by pushing in the pin control valve
located at the front of the slider side rail driver side.
3.
Release the tractor brakes. Carefully drive forward or backward
until the sliding suspension is at the desired location. Do not
exceed 3 mph (5 km/h).
4.
Pull out the pin control valve. Check that the suspension is
locked securely. The main body of each lock pin must extend
through the holes in the rails.
5.
Immediately lock the locator stop bar in both body rails located
directly behind the slider.
6.
With the trailer brakes applied, gently rock the trailer backward
and forward to ensure that the sliding suspension is locked
correctly. Check that the main body of each lock pin extends
through the holes in the rails.
7.
Follow Step 6 at each stop before you operate the vehicle and
pull the trailer.
