Harken Vang-Master
7
Commisioning
Attach the vang to mast and boom fittings. Add air pressure using a
high quality bicycle pump with Schrader valve fitting. Remove cap and
use a pump capable of pumping more than 100 psi (690 kPa). The
amount of pressure will determine the boom angle and the return rate.
Maintenance
Harken equipment is designed for minimal maintenance. However, some upkeep is required to give the best service and
comply with the Harken limited warranty. 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. Flush with
fresh water.
The VM should not need rebuilding even over long periods. If it is not operational contact Vang-Master or Harken to discuss
possible rebuilding.
WARNING! The Vang-Master contains compressed air and may cause injury if service is attempted by non-specialized personnel.
Do not disassemble the Vang-Master unless you are an authorized Harken service center.
IMPORTANT! Exposure to some teak cleaners and other caustic solutions can result in discoloration of part and is not covered under
the Harken warranty. See www.harken.com/manuals or the Harken catalog.
Decommissioning
When removing the boom for winter storage or transport, DEPRESSURIZE the cylinder before removing or disconnecting the
vang. Remove cap and use a small screwdriver to press the canter valve post to let air out.
Schrader air valve
Tip:
To make is easier to add air, use the main halyard to hold the boom
up about 10 degrees from the sailing position. When you think you have
enough pressure, ease off on the main halyard to check the boom angle.
Pull down on the end of the boom and check the return rate. If boom is
on the soft side, add more pressure. If there is too much pressure, use a
small screwdriver to press on the valve post to let air out.
Use halyard to lift boom while pumping air.
