Strictly follow all instructions to avoid an accident, damage to 

your vessel, personal injury or death. See www.harken.com/

manuals for additional safety information.

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  

one to two 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. 

For additional safety, maintenance and warranty information see www.harken.com/

manuals or the Harken

®

 catalog.

Maintenance

Inspect

Frequently inspect shackles and control block fittings for signs of fatigue and replace as 

necessary. Make sure every installation includes Harken track end stops. Arrange control 

tackle so cars do not hit end stops under load.
