Warranty
Inspect
Carefully inspect track and mounting hardware for any signs of loosening, cracks or
damage. Inspect end stops to make sure they are secure and that there are no cracks or
damage. Arrange control tackle so cars do not hit end stops under load.
WARNING! Failure to inspect tracks and stops can result in track
pulling off deck suddenly and unexpectedly during high 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 then flush bearings with fresh water.
Do not use spray lubricants because ball bearings may skid not roll. Apply
a few drops of McLube
®
OneDrop
™
to ball contact surfaces of track.
Roll car back and forth through OneDrop
™
several times to distribute
onto bearings. Wipe remaining OneDrop
™
off track. OneDrop
™
is
preferred but you can also use one to two 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.
