What routine maintenance schedule should I follow for the Spectrum 375?

Check gas/air pressure and inspect the torch tip, electrode, and shield cup for wear each use. Check the shield cup shutdown system weekly. Every 3 months, check air filter/regulator, damaged or unreadable labels, cracked parts, gas/air hose, and torch body and cable. Replace the air filter element if it shows dirt and moisture. Perform more frequent maintenance during severe conditions. Always disconnect power before maintaining the unit. (Page 24)
