Harken equipment requires minimal maintenance, but some is required to give the best service and to
comply with Harken's limited warranty.
It is important to keep equipment clean by frequently flushing with fresh water. In corrosive
atmospheres, stainless parts may show discoloration around holes, rivets and screws. This is not
serious and may be removed with a fine abrasive.
With the exception of winches, do not use grease unless specifically recommended in the instruction
sheets.
IMPORTANT! Exposure to some teak cleaners and other caustic solutions can result in discoloration
of part and is not covered under the Harken warranty.
