Inspection And Repair; Application; Areas Of Application - Manitowoc Grove RT765E-2 Service And Maintenance Manual

LUBRICATION
• Allow the crane to dry thoroughly. You can accelerate
drying by using compressed air to remove excess water.
NOTE: Polishing and waxing (using an automotive-type
wax) is recommended to maintain the original paint
finish.

Inspection and Repair

• Immediately following cleaning, Manitowoc Crane Care
recommends an inspection to detect areas that may
have become damaged by stone chips or minor
mishaps. A minor scratch (one that has not penetrated
to the substrate surface) can be buffed with an
automotive-type scratch remover. It is recommended
that a good coat of automotive wax be applied to this
area afterwards.
• All identified spots and/or areas that have been
scratched through to the metal should be touched up
and repaired as soon as possible to prevent flash
rusting. To repair a major scratch (down to bare metal) or
minor damage, follow these procedures:
NOTE: Manitowoc Crane Care recommends that a
qualified body repairman prepare, prime and paint
any major scratch(es) or minor damage.
To the extent any damage is structural in nature,
Manitowoc Crane Care must be contacted and consulted
as to what repairs may be required.
• 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 insure 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.

RT765E-2 SERVICE MANUAL
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
(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.

Areas of Application

Refer to Figure 9-13 and Figure 9-14.
• The underside of the unit will have full coverage of the
rust inhibitor. These are the only areas that a full coat of
the rust inhibitor is acceptable on the painted surfaces.
Areas include; Valves, hose end and fittings, Swivel,
pumps, axles, drive lines, transmission, slew ring
fasteners and all interior surfaces of the frame.
