Vang-Master is a quality made product and should require little maintenance.
We recommend that you hose off your vang when washing your boat. Take care to spray the fittings and its block and tackle to remove dust or salt.
Adding Air to Pneumatic Cylinder
Vang-Master comes with its own air pump. The pump is used to either adjust the return force to meet your boat's needs, or to add more air.
To add air to the cylinder, simply affix the pump hose to the Schrader valve located at the base of the vang. Pump as you would a bicycle tire pump to achieve the appropriate pressure.
Adjusting Vang Return Force
To adjust return force, simply add or delete air from the pneumatic cylinder via the Schrader valve.
Quick Test: Fill the cylinder with air to desired pressure. Go to rear of boom, press down and check resistance. Adjust the return force pressure to suit your requirements.
