Harken equipment requires minimal maintenance, but some maintenance is required to give 
the best service and to comply with Harken's limited warranty.
It is important to keep equipment clean by frequent flushing with fresh water. In corrosive 
atmospheres, stainless parts can show discoloration around holes, rivets, and screws. 
This is not serious and can be removed with a fine abrasive. Flush blocks thoroughly 
with fresh water. Periodically, disassemble the blocks and clean with detergent and fresh 
water. Important: Exposure to some teak cleaners and other caustic solutions can result in 
discoloration of part and is not covered under the Harken warranty.

For additional safety, maintenance, and warranty information; www.harken.com/manuals or 
the Harken catalog.
