Air controls (venturis) do not introduce air; jets feel flat even with air knobs open.

Safety first: Turn off power before removing any air control components.

• Operate controls: Turn Everlast air control knobs fully open and closed several times to free any sticking parts.
• Inspect air intakes: Check that air intake openings are not blocked by debris or snow.
• Check for water in lines: If water is visible in clear air tubing, drain and dry the lines and ensure check valves are functioning.
• Replace air controls: If knobs are cracked or do not turn smoothly, replace the Everlast air control assemblies.
