LUBRICATION PROCEDURE AND CHARTS OPERATOR MANUAL NBT50

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.
