Important Safety Notice

Although a 40-degree spray nozzle produces a wider spray pattern than more concentrated spray tips, high-pressure water can still cause injury or property damage if used improperly. Never direct the spray toward people, animals, electrical equipment, glass, painted surfaces, or delicate materials. Always wear appropriate personal protective equipment when operating pressure washing equipment.

Maintenance Recommendations

• Inspect the nozzle regularly for wear or orifice enlargement.
• Flush clean water through the nozzle after each use.
• Remove debris or mineral deposits as necessary.
• Replace the nozzle if spray pattern quality declines.
• Store in a clean, dry location when not in use.
• Check threads periodically for wear or damage to ensure a secure connection.
