Important Safety Notice

Always wear appropriate personal protective equipment when operating pressure washing equipment. While a 25-degree nozzle provides broader coverage than concentrated spray tips, high-pressure water can still cause injury or damage if used improperly. Avoid directing the spray toward people, animals, electrical equipment, delicate surfaces, glass, painted finishes, or any area susceptible to damage from high-pressure water.

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.
