3. Loosen the thumbscrew (1) on the side of the Focus Carriage (if already attached). Insert the cone (2)
into the cone base on the bottom of the Focus Carriage until it bottoms out and gently tighten the
thumbscrew.
Air Flow adjustment
The needle valve can be used to adjust air flow for different applications. It is best to start with the needle
valve at maximum flow (turn the needle valve counterclockwise until it seats), then adjust as necessary.
Removal
Loosen the thumbscrew and pull the Cone downwards. Leave the thumbscrew attached to the Focus
Carriage by re-tightening. Detach the hose from the needle valve by using a small wrench or needle nose
pliers to loosen the nut that attaches the hose to the needle valve and unthreading the nut from the needle
valve. The needle valve will stay with the carriage.
