Keep your equipment clean and free-running by frequently flushing with fresh water.
Periodically clean with mild detergent and water solution. Spin sheaves to distribute
soap solution evenly. Occasionally disassemble and clean rollers and balls with
detergent and water solution. Assemble using blue Loctite ® on screws.
Stainless fasteners which pass through aluminum blocks should be coated with an
antiseize compound such as Tef-Gel ® .
IMPORTANT! Exposure to some teak cleaners and other caustic solutions can result in
discoloration of part and is not covered under the Harken warranty.
