VEVOR Hydraulic Strut Spring Compressor User Manual

1. Introduction

The VEVOR Hydraulic Strut Spring Compressor is a robust tool designed for the safe and efficient disassembly and maintenance of strut springs and shock absorbers in various vehicle types, including sedans, SUVs, off-road vehicles, and pickup trucks. It features a powerful hydraulic jack with a 4.5-ton load capacity and a 1-ton rated compression force, ensuring effortless handling of heavy springs. Its stable suspension system and multiple safety features prioritize user security during operation.

2. Safety Information

WARNING: Spring compression can be extremely dangerous. Always follow all safety precautions and instructions carefully. Failure to do so may result in serious injury or death.

• Always wear appropriate personal protective equipment, including safety glasses and heavy-duty gloves.
• Ensure the compressor is placed on a stable, level surface. For added security, utilize the pre-drilled holes in the base to anchor the unit to the ground.
• Verify that the spring and strut assembly are securely seated in the clamps before initiating compression.
• Always attach the 39.4-inch extended safety chain to secure the springs and prevent bouncing during compression.
• Do not exceed the rated compression force of 1 ton. The hydraulic jack has a 4.5-ton load capacity, but the compression force is limited to 1 ton.
• Keep hands and other body parts clear of moving parts during operation.
• Inspect the unit for any damage or wear before each use. Do not use if any components are damaged.
• Only use the provided small and big spring clasps. Ensure the correct clasp size is used for the spring being compressed.
• When releasing pressure, do so slowly and in a controlled manner by pressing the second pedal.

4. Assemble Upper and Lower Clamps:
   • Insert the upper clamp assembly into the top section of the main column. Ensure it is oriented correctly (arrow pointing upwards) to withstand greater loads. Secure it with the provided pin and cotter pin.
   • Slide the lower clamp assembly onto the hydraulic rod. Secure it with the provided pin and cotter pin.

6. Anchor the Unit (Recommended): For maximum stability and safety, use the pre-drilled holes in the H-shaped base to anchor the compressor to the ground using appropriate fasteners (not included).

5. Operating Instructions

Follow these steps to safely operate your VEVOR Hydraulic Strut Spring Compressor:

1. Prepare the Strut Assembly: Ensure the strut and spring assembly is clean and free of debris.
2. Position the Strut: Carefully place the strut and spring assembly into the installed spring clasps. Ensure it is seated firmly and centrally within both the upper and lower clasps.

6. Perform Work: Once the spring is sufficiently compressed and held securely, you can proceed with disassembling the strut or performing necessary maintenance.
7. Release the Spring: After completing your work, slowly press the second foot pedal (release valve) to gradually lower the clamp and decompress the spring. Ensure the spring is fully decompressed before removing the assembly.
8. Remove Strut Assembly: Once the spring is fully decompressed, carefully remove the strut and spring assembly from the clasps.

6. Maintenance

Proper maintenance will extend the life of your VEVOR Hydraulic Strut Spring Compressor:

• Cleaning: After each use, wipe down the unit with a clean cloth to remove any dirt, grease, or debris.
• Lubrication: Periodically apply a light coat of machine oil to all moving parts, including the hydraulic rod and pivot points, to ensure smooth operation and prevent rust.
• Inspection: Regularly inspect all bolts, pins, and the safety chain for tightness and wear. Check the ductile cast iron clasps for any signs of cracks or damage. Inspect the hydraulic jack for any leaks.

• Storage: Store the compressor in a dry, clean environment when not in use to prevent corrosion.
• Hydraulic Fluid: If the hydraulic jack's performance degrades, consult a qualified technician for hydraulic fluid level checks and refills. Do not attempt to service the hydraulic system yourself unless properly trained.
