Operating Instructions

The EZ-Latch coupler features a simple-to-use latching
mechanism� Hooking up is as easy as dropping the
coupler on to your hitch ball� Simply make sure that the
coupler is properly lined up with the ball, then lower
the coupler� The coupler will automatically open and
latch into place when lowered onto the hitch ball� To
disengage coupler, pull up on latch and raise coupler
off of hitch ball� Return the coupler latch to the latched
position to ensure that coupler is ready to be latched
again� The coupler features a strong composite
handle, If the handle does get damaged or becomes
missing, the coupler is still completely operational
until the handle can be replaced� Replacement parts
can be purchased through your Airstream Dealer� See
additional information included in your owner's packet�
Always make sure coupler is properly attached and
latched before towing.

Axle and Running Gear Assembly

Each rubber torsion axle is aligned during
manufacturing, and double-checked on a random
basis� Alignment after delivery is the customer's
responsibility�
Hitting chuck holes or rough railroad tracks while
traveling straight will only cause misalignment after
the tire has struck such objects many times� Of
course, a deep enough hole can affect the alignment
immediately�
The worst culprit is a curb because they are normally
struck at an angle� Rear axles are occasionally
damaged when people are attempting to park beside a
curb while backing up their trailer�
The trailer axle(s) is bent upward in the middle� This
bend is normal and is how the camber is obtained�
Also, toe-in is built into the axle by very slight bends in
the axle tube on each end�
Tire wear indicates misalignment� Check with your
dealer for the nearest location with the proper
equipment to correct the trailer's alignment�
Refer to Section 8 - Maintenance for camber and toe-in
specifications.

Nev-R-Lube Drums/Bearings

All International models are equipped with Nev-R-
Lube bearings� Dexter's Nev-R-Lube bearings are
comprised of opposed tapered roller bearing cones
sealed inside a precision-ground, one-piece, double-
cup arrangement� These bearings are designed with
a small amount of axial end-play� The end-play is
essential to the longevity of the bearing's service life�
Refer to Section 8 - Maintenance for Nev-R-Lube
Bearing inspection�

Power Jack

A switch located on the bottom of the housing operates
the power jack� When the jack is fully extended or
retracted, internal limit switches automatically shut off
the motor�
The jack is wired directly to the battery and has a
spade fuse between the battery and the power head�
For fuse information and part number, refer to section
