NOTE:
Manitowoc Crane Care recommends that a
qualified body repairman prepare, prime and paint
any major scratch(es) or minor damage.
For scratches and marks in highly visible areas:
•
Sand to remove the scratch and feather outward from
the mark to blend the repair into the original surface.
Body putty may be applied as necessary to hide the
defect; then sand smooth.
•
Cover all bare metal with a primer that is compatible with
the original paint finish and allow to dry thoroughly.
•
Prepare the surface prior to applying the finish coat of
paint.
•
Apply a finish coat paint using accepted blending
techniques. Use of original paint colors is recommended
to ensure the best color match possible.
For scratches and marks in areas of low visibility:
•
Consider touching up the spots with a brush technique
to cover the bare metal. This will retard the effects of
corrosion and enable you to do the repair at a later time
during a normal maintenance interval.
Spots should be touched up with quality paint. Primers tend
to be porous; using a single coat of primer only will allow air
and water to penetrate the repair over time.
Application
Depending upon the environment in which a crane is used
and/or stored, the initial factory application of Carwell T32-
CP-90 should help inhibit corrosion for up to approximately
12 months.
It is recommended that the treatment be periodically
reapplied by the crane owner after that time to help continue
to protect against corrosion of the crane and its components.
However, if a crane is used and/or stored in harsh
environments (such as islands, coastal regions, industrial
areas, areas where winter road salt is regularly used, etc.),
reapplication of treatment is recommended sooner than 12
months, e.g., repeat treatment in 6-9 months.
•
Do not apply to recently primered and painted areas for
at least 48 hours after paint is properly dried and cured.
For minor touch up areas a 24 hour period is needed for
cure time before applying treatment.
NOTE:
Unit must be completely dry before applying
treatment.
•
Do not allow product to puddle or build-up on weather
stripping, rubber gaskets, etc. Unit should not have
puddles or runs evident anywhere.
•
To ensure proper coverage of treatment, the product
needs to be fogged on the unit.
•
Use of pressure pots to apply the treatment to the unit
being processed is recommended.
•
Carwell treatment is available in 16 ounce spray bottles
from Manitowoc Crane Care (order part number
8898904099).
•
After application of the treatment is complete, wash or
clean film residue from lights, windshield, grab handles,
ladders/steps and all access areas to crane, as
necessary.
Please contact Manitowoc Crane Care should you have any
questions.

•
Superstructure applications are; hose ends and fittings,
wire rope on hoist roller tensioning springs on hoists, all
unpainted fasteners and hardware, valves, slew ring
fasteners and all bare metal surfaces.
•
Boom applications areas are: pivot pins, hose ends and
