Troubleshooting
Harken equipment is designed for minimal maintenance, but some maintenance is required for optimum and safest possible operation and to comply with
the Harken limited warranty. In general, the most important aspect of maintenance is to keep your equipment clean by frequently flushing with fresh water.
In corrosive atmospheres, stainless parts may show discoloration around holes, rivets, and screws. This is not serious and may be removed with a fine abrasive.
With the exception of winches, do not use grease unless specifically recommended in the instruction sheet.
Flush blocks thoroughly with fresh water. Periodically, disassemble the blocks and clean with detergent and fresh water. Lubrication is not required.
IMPORTANT! Exposure to some teak cleaners and other caustic solutions can result in discoloration of part and is not covered
under the Harken warranty.

Problem Probable Cause Solution
Cars bind.
Slider damaged or missing. Check and/or replace slider.
Too much friction.
Spray a small amount of McLube ® Sailkote ™ lubricant
in underbody track slot of all cars. If possible spray cars
off boat. If this is not possible, use a drop cloth to keep
overspray off deck. McLube will cause slippery decks
which can result in loss of footing (page 16).

Cap screws and nuts are overtightened on plastic cars. Loosen nut until screw end is even with plastic in nut.
Can't raise sail, cars stop at switch. Car loaded upside down. Pins in car on wrong side. Remove car, flip it around and reload.
Nut on Battcar is not holding. Locknut has been used too many times. Get new 6 mm locknut.
