chemicals and should be avoided when that
is the case.
Removing road lm, contaminants and
brake dust (all of which retain moisture) is
critical to ensuring that the wheels will re-
tain their luster and quality nish for a long
period of time. Any exposure to a harsh
winter climate, particularly road salt and/
or chemicals, or submersion in salt water at
any time, requires immediate cleaning.
NEVER CLEAN WHEELS THAT ARE
HOT. Allow wheels to cool or cool them with
running water. If the wheels are too hot, sig-
nicant damage can occur to the wheels.
Wheels must always be cool or cold to the
touch prior to cleaning. Failure to allow
wheels to cool suciently can result in
damage that is not covered under warranty.
It is also important to seal the wheels
with a sealant that reduces static and resists
brake dust. Check at an automotive supply
store for an appropriate sealant.
Lug Nuts or Wheel Bolts
Loose wheel mounting nuts (lug nuts) can
cause more than just an annoying wheel
wobble—it’s possible to lose a wheel. Be-
fore each trip check for loose or missing
lug nuts/wheel bolts.
Ensure that all lug nuts are secure prior to
every time the trailer is towed. Failure to do
so can ultimately cause a wheel to disen-
gage from the hub. This can cause damage
to the trailer that may not be covered under
warranty, and serious injury or even death
to the driver, any passengers and/or other
motorists.
When tightening the
lug nuts, use the cor-
rectly sized wrench.
The wrong size can
round off the lug
nuts and render them
useless. If you lose
a lug nut, replace it
promptly. The cor-
rect size varies with different models, so
verify the proper size with an authorized
MasterCraft dealer.
Take special care to ensure that the re-
placement lug nut is the correct type. While
the threads of the lug nut may match, the
lug nut may be a size that does not hold the
wheel securely against the hub, even when
fully tightened. Be certain a replacement
lug nut is an exact match for the original.
• Ensuring that lug nuts on trailer wheels
are tight and properly torqued is an im-
portant responsibility that trailer owners
and users need to be familiar with and
practice. Inadequate and/or inappropri-
ate lug nut torque (tightness) is a major
reason that lug nuts loosen during use.
Loose lug nuts can rapidly lead to a
wheel separation from the hub, with po-
tentially serious safety consequences.
• Check the lug nut tightness often, espe-
cially during the rst few hundred miles
of the trailer’s use. You should always
check the torque at the beginning of any
long trip and every time a wheel is re-
moved.
• You must use a torque wrench to ac-
curately indicate the amount of torque
that you are applying to the lug nut.
