Inspect
Frequently inspect shackles and control block fittings for signs of fatigue. Replace as necessary.
Make sure every installation includes Harken track endstops. Arrange control tackle so cars do
not hit endstops under load.
Maintenance
Traveler cars: Clean by frequently flushing with fresh water. Periodically clean
car by squirting a detergent/water solution into center openings. Roll car back
and forth to distribute evenly. Flush bearings with fresh water.
Do not use spray lubricants because ball bearings can skid, not roll. Once car and
track are dry, apply one (1) to two (2) drops of McLube
®
OneDrop™ ball bearing
conditioner to ball contact surfaces of track. Roll car back and forth through
OneDrop conditioner several times to distribute onto bearings. Wipe remaining
OneDrop off track. OneDrop conditioner is preferred, but you can also use one (1)
to two (2) drops of a light machine oil. Too much oil attracts dirt.
Track: Clean with detergent and 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.
