Harken equipment requires minimal maintenance,  

but some is required to give the best service and  

to comply with Harken’s limited warranty.
Keep equipment clean by frequent flushing with fresh 

water. Periodically clean with mild detergent and 

water solution. Spin sheaves to distribute soap  

solution evenly.
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.
IMPORTANT! Exposure to some teak cleaners and 

other caustic solutions can result in discoloration of 

part and is not covered under the Harken warranty.
