specified for each trailer wheel. Failure to properly install
and maintain the lug nuts could result in the trailer wheel
coming off during operation. Such failure can result in
serious injury or death, as well as property damage.
Follow these instructions for ensuring proper installation and
torque for the lug nuts:
• Use a torque wrench. No other wrenches or similar tools are
appropriate for use, except in an emergency.
• Keep a record of readings. If a lug nut or nuts routinely loses
torque, it is symptomatic of a bigger problem that should be
brought to the attention of your authorized Malibu dealer to
remedy.
• Use the following
pattern to tighten
lug nuts: On the first
round, tighten to
45 ft.-lbs. Tighten a
second time to 70
ft.-lbs. Tighten again
to 90 ft.-lbs. And on
the final time, tighten
to 120 ft.-lbs. Do this
in a "star" pattern; do
not simply go around
clockwise or counter-
clockwise. The cross effort will ensure a correct reading.

Tires

Always keep tires to the specified inflation. The tire manufacturers
will indicate the proper air pressure on the sidewall of the tire; this
information is also available on the tire manufacturer's website.
Be sure to have a spare tire on all outings. Even new tires can be
damaged or lose air.
failure while in use. This can result in loss of control of
the trailer, which can lead to serious injury or death.

When storing the trailer, periodically check the tire inflation. Loss
of inflation can signal a problem and can shorten the duration of
the tire's life. Also shield tires from UV rays, which can significantly
damage rubber. If it is possible to support the trailer frame with jack
stands or concrete blocks, this can help lengthen the life of the
trailer's springs on trailers so equipped, as well as relieving pressure
on the tires.
Although the tires selected for the Malibu trailer are durable,
eventually they will require replacement. DO NOT mix radial and
bias-ply tires. This could affect handling and, ultimately,
safety. Be certain that the replacement tires meet the trailer
requirements and integrate with the remaining tires.
Brakes
The Malibu trailer brakes are "surge" brakes, which can be
effective and helpful particularly when towing heavy loads. (NOTE:
Not every jurisdiction allows surge brakes. Check with authorities in
the area in which you will be towing.)
When the tow vehicle slows or stops, the trailer's momentum
moves against the hitch ball and causes hydraulic pressure in the
master cylinder (located in the trailer's tongue) to transfer pressure
through the brake lines, causing the brakes to engage.
The trailer brakes should always be maintained in top condition.
This includes checking the fluid level in the actuator regularly. The
loss of brake function can result in loss of control or the inability to
stop the trailer, which could lead to serious injury or death.
See the information provided above about the breakaway cable.
The breakaway cable should NEVER be used as a substitute for
braking or as a parking brake.
Note that brakes will be submerged when the trailer is backed into
the body of water to unload or load the boat. If the brakes (and/or
wheels) are hot, it is recommended to wait a brief period of time and
allow them to cool before submerging. Excessive heat meeting cooler
water can cause damage to the components, especially the calipers
and rotors. Also, if the trailer is submerged in salt or brackish water,
be sure to carefully and completely rinse the entire trailer after the
outing. Salt and exceptionally dirty fresh water can cause damage to
the trailer components, which is not covered under warranty.
Always clean the trailer with a fresh-water rinse and/
or use of mild soap after an outing in which parts of the
trailer are submerged.
Salt and brackish fresh
water can damage trailer
