Key Features of the SCH GWCS9 Sprayer

Performance Specifications

The sprayer features a 12-volt diaphragm pump with a delivery rate of 7 liters per minute, operating under a pressure of 3.1 bar. It can handle fluid temperatures up to 54 °C. Spray width extends to 2440mm (96 inches).

Operational Weight

Dry weight approximates 15kg with a full operational weight around 84kg.

Safety Instructions

• Ensure secure attachment to your vehicle and avoid using the sprayer near people.
• Prevent chemical contact with food, and avoid inhaling sprayed substances.
• Operate the sprayer wearing appropriate protective clothing, and do not spray in windy conditions or near water bodies.
• Regularly test the sprayer with water before using chemicals and never let the pump run dry.

Preparing and Using the GWCS9 Sprayer

Setup

Connect the orange power cable to your towing unit's battery. Arrange the boom properly ensuring the 'V' cut on the spray nozzles faces the ground at a height of about 460mm (18 inches). Secure all fittings and adjust the boom as necessary for travel or operation using thumb screws.

Operation

For transport, fold in the outer wing bars of the boom; unfold them to begin spraying. Adjust the nozzles as needed to customize the spray width. For smaller or targeted areas, hand spraying can be utilized by switching off the sprayer, adjusting the delivery hose from the spray bar to the brass trigger lance, and then resuming operation.

Maintenance and Troubleshooting

Regular Care

• Flush the tank with clean water after each use and perform thorough washes bi-annually.
• Check and clean the pump's inlet filter and ensure the 'O' ring is properly positioned.
• Maintain the chassis wheels and thumb screws with regular greasing.
• Inspect and clean spray nozzles and filters for consistent spraying patterns.
• Apply preserving oil in the off-season to extend the life of the sprayer.

Troubleshooting Tips

• Check electrical connections and hose positions if the pump fails to operate or deliver properly.
• Ensure that all fittings and nozzles are clear of obstructions.

Conclusion

The SCH GWCS9 is a powerful and versatile tool for gardeners and agricultural professionals, designed for ease of use and efficiency in large-scale spraying tasks. Regular maintenance and attention to safety can help ensure it performs optimally for all your landscaping needs.
