No. 4002
25XPL Operation
Models Affected - 25XPL
This bulletin is intended to describe how to operate the lift axle of the 25XPL trailer. The lift axle should always
be lifted, raised, unless the two rear axles are loaded in excess of 34,000 pounds. If you should need to use the
lift axle, always have the axle lifted until after the trailer is loaded.
Warning!
The axle should always be lifted during the loading and unloading of equipment or frame
bending may occur. A decal, see below, should be affixed to the trailer near the lift control valve that states this.
After the trailer has been loaded you may lower the lift axle by moving the lift control valve lever. Since
the trailer loaded, the main air bags should inflate immediately to same height as the rear two axles.
Warning!
If the lift axle appears to raise the trailer up higher then the rear two axles, lift axle
immediately and adjust automatic height control valve. The axle ride height should be set for 6", the same as the
loaded rear axle height. See separate instructions for adjusting.
Note, if the axle is lowered, without a load on the trailer, the main air bags should not inflate since
the automatic height control valve has not sensed the lower deck height of a loaded trailer. If the main air
bags do inflate, the automatic height control valve will need adjusting. See separate instructions for adjusting.
