GRT8100 OPERATOR MANUAL MAINTENANCE AND LUBRICATION
Application
Depending on the environment in which a crane is used and/
or stored, initial factory application of Carwell
®
T32 (CP-90)
should help inhibit corrosion approximately 12 months. It is
recommended 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. Refer to
Figure 5-17 and Figure 5-18 for application points.
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, product needs to be fogged
on the unit.
• Use of pressure pots to apply treatment is
recommended.
• Carwell
®
treatment is available in 16-ounce spray
bottles from Manitowoc Crane Care (order part number
8898904099).
• After treatment application is complete, wash or clean
film residue from lights, windshield, grab handles,
ladders/steps and all access areas to crane, as
necessary.
Contact Grove Crane or Manitowoc Crane Care should you
have any questions.
