Jump to the sectionProduct Overview
The Sealey 1000KG Air Operated Coil Spring Compressor is a robust, professional-grade tool engineered for the fast and safe compression of automotive road springs. This unit is designed to handle a wide range of spring configurations and diameters, making it an essential piece of equipment for suspension work in professional workshops. It features a heavy-duty frame, a safety locking guard, and an air-operated ram controlled by a foot pedal for precise operation.
Safety Guidelines
Safety is paramount when working with high-tension springs. Always wear approved eye and hand protection. Keep hands and fingers away from the spring and compressing jaws during operation. Never allow untrained personnel to use the equipment. Before starting, ensure the work area is clean, well-lit, and that you have stable footing. Always stand to one side of the compressor when applying pressure. Never leave a compressed spring unattended or under compression for prolonged periods, such as overnight. If the spring or strut is not correctly located in the jaws, stop immediately to prevent dangerous sideways forces.
Assembly and Preparation
The unit requires assembly by two people. Ensure the feet are securely bolted if permanent installation is desired. The safety guard must be correctly installed and locked before use. Before connecting the air supply, ensure the foot control lever is in the off position. The air supply must be clean and not exceed 116psi (8bar). Drain the air supply water separator daily to prevent internal damage to the ram.
Operation
To compress a strut, select the appropriate yoke or clamp for the spring size and secure it with the locking pin. Position the lowest coil in the lower yoke and the upper clamps on the uppermost coil. Ensure the spring is seated securely in the recesses. Use the safety chain to secure the spring and close the safety guard. Gradually press the foot pedal to compress the spring. Once the strut is loose, remove the top nut. When re-fitting, reverse the process, ensuring the spring is correctly located before slowly releasing the pressure.
Maintenance and Storage
Regular maintenance ensures longevity and safety. Before each use, inspect the unit for damage or wear. Periodically clean the sliding columns and apply a light coating of transmission oil. If the unit is to be stored for an extended period, disconnect the air supply, discharge any remaining air, and apply a small amount of air tool oil to the inlet to prevent corrosion. Store in a safe, dry, and childproof location.
