The amount of pressure which releases the lock can be adjusted by changing the angle of the joints. Larger the angle,
the more easily the lock releases. When the adjustment nut is tightened (picture 19) less pressure is required and when
the nut is loosened more pressure is required. The angle between joints should be at least 5° to enable the release
mechanism to function as designed (picture 20). Never adjust the angle totally straight!
