1- Before testing your system, make sure you have adequate air supply. Let the compressors run for 2-3 minutes before you switch the system ON, adjust the regulator of the filter/lubricator/regulator unit to 100 psi. Also adjust the mineral oil supply ( in the lubricator ).

2- Adjust the filter/lubricator/regulator oil injection rate so that a drop of oil is hanging in the sight dome ( not dripping ). The amount of oil infected is controlled through l the screw behind the sight dome. Proper adjustment ls about 1/2 turn open.

3- Gently move the gyro cage back and forth on 4 seconds interval and notice the followings :

a- one gauge goes up to at least 80 psi while the other gauge drops to zero instantly. As you reverse the movement of the gyro cage, the gauges will also reverse their readings. That is the gauge which was reading 80 psi will drop instantly to zero and the other gauge will go up to 80 psi.
b- When the front of the gyro ls moved to port side, the port fin will go up and the starboard fin will go down. When you reverse the movement of the gyro. the fins will reverse their actions. If the fins do not follow this sequence, it means that the green and red tubing are reversed at the control unit.
c- When you release the gyro, the pressure on both gauges will be approximately the same ( within 5 psi ) and the fins will be free and may be easily moved by hand.

Testing Procedures

1- Reverse the red and green tubing et the control unit.

2- Put the vessel at cruising speed, turn the stabilizer ON and allow 30 seconds for the gyro to pick up its speed. Gently move the gyro to one side then release it quickly. The vessel will roll approximately 20 degrees, it should roll back and forth on its on. If the vessel does not maintain the roll, increase the sensitivity of the system ( by increasing the gyro speed ) through the pressure inserted on the rotor in an increment of one psi at a time. Repeat ( the roll test until you maintain a steady roll.

3- When the roll test is completed, reverse the green and red tubing at the control unit ( normal position ).
