CAUTION
Do not direct high pressure water onto
seals
or flexible hoses. Water may en-
ter the part which will contaminate the
system lubricants and fluids. To pre-
vent damage to these components,
keep a gentle flow of water moving at
all times. Failure to comply may result
in equipment damage.
CAUTION
Do not direct high pressure water onto
electrical
components, plug connec-
tors, seals or flexible hoses on the en-
gine. Failure to comply can accelerate
corrosion and degrade electrical com-
ponent which may cause a fire or
equipment damage.
To prevent rust, keep chromed parts clean
and protected with wax at all times,
especially in winter conditions when the
roads are salted.
•
If necessary, use a commercial
chrome cleaner to remove light
rust.
• Chrome surfaces are best cleaned
with fresh water
. Wipe dry to
preserve their luster. A commercial
chrome cleaner will remove light
rust. After cleaning, wax flat
surfaces and apply a thin coat of
rust preventive lubricant around
bolts or other fasteners.
• Clean aluminum wheels and
bumpers with cool water. Tar-
remover will get rid of heavy
deposits of road grime. To prevent
spotting, wipe aluminum surfaces
dry after washing.
• Under corrosive conditions, such
as driving on salted roads, clean
aluminum parts with steam or high-
pressure water from a hose. A mild
automotive soap solution will help.
Rinse thoroughly.
To maintain the tailpipe's quality finish,
wash the tailpipe with a soft cloth, mild
automotive soap, and water or glass
cleaner. A non-abrasive chrome polish can
be used sparingly on hard-to-clean areas.
DO NOT clean your high-heat chrome
using scouring pads, abrasive chrome
polish, highly acidic chemical cleaners or
any other abrasive cleaners.
Even high quality stainless steel parts can
rust under prolonged exposure to salt
water, especially when the salt-laden
moisture is held against the metal surface
by road grime. It is important to frequently
clean salty moisture and grime from
stainless steel surfaces.
• If surface rust is encountered,
wash the surface and use a
commercial polishing compound to
clean off the rust, followed by a
coating of wax.
• Never use steel wool when
cleaning stainless steel. Minute
particles of the steel wool can
become embedded in the surface
of the stainless steel part and
cause rust staining.
Weather Stripping
Frequent washing of the vehicle is required
to remove road grime and contaminants
that can stain and oxidize paint and
accelerate corrosion of plated and polished
metal surfaces. Waxing offers added
protection against staining and oxidation.
Do not apply wax in the hot sun and do not
friction burn the paint with a buffing
machine. Occasionally spray weather-
stripping on doors and windows with
silicone compound to help preserve
resiliency. This is especially useful in
