Trailer Storage
Preparation
If your trailer is to be stored for an extended period
of time or over the winter, it is important that the
trailer be prepared properly.
1.
Remove the emergency breakaway battery and
store inside, out of the weather. Charge the battery
at least every 90 days.
2.
Jack up the trailer and place jack stands under
trailer frame so that the weight will be off the tires.
Never jack up or place jack stands on the axle tube
or on the equalizers.
3.
Lubricate mechanical moving parts that are
exposed to weather, such as the hitch and suspen-
sion parts.
NOTE: On oil lubricated hubs the upper part of
the roller bearings are not immersed in oil and are
subject to potential corrosion. For maximum
bearing life it is recommended that you revolve
your wheels periodically (every 2-3 weeks) during
periods of prolonged storage.

U-bolt nuts per recommended torque values.

temperature brake lubricant. (LUBRIPLATE or
equivalent).
CAUTION: Do not get grease or oil on brake linings
or magnet face.
7.
Remove any rust from braking surface and
armature surface of drums with fine emery paper or
crocus cloth. Protect bearings from contamination
while so doing.
