The Engraver on the Dragon A150 is powered by a single air source. The air pressure to
the Engraver is controlled by a regulator located on top of the Head of the machine. Proper
performance of the Engraver is dependent on air pressure. Bend-Tech recommends setting
initial air pressure to 70-80 PSI.
When troubleshooting the Engraver, ensure there are no leaks at air line connections. Ensure
air lines are not cracked, kinked or broken.
