1.Check the cylinder gauge to see if it is FULL. Cylinder full - Remove the cylinder and
turn the unit Off. Perform the Cylinder Prefill Inspection on page 14 with a cylinder
that is NOT FULL.

compressor to start. If the psi is above 1500 the compressor identifies the cylinder as
full.

the cylinder and reinstall. Turn the compressor On.
