TO COMPRESS A SPRING REMOVED FROM A VEHICLE.

1. Measure the outside diameter of the spring to be compressed and select 

the correct set of jaws to fit the spring.

2. Mount the selected jaws on the compressor body, using the retaining bolts 

and tighten securely.

3. Rotate the hexagonal nut, to drive the jaws apart to the length of the 

spring and to allow compression of as many windings as possible.

4. Place the spring compressor onto the spring, ensuring the spring seats 

correctly between the safety lips and the outer ribs and cannot slide out 
during compression.

5. Ensure the jaws and body are correctly aligned.

6. Rotate the hexagonal nut and compress the spring.

7. Secure the spring with a spring clamp or other suitable device.

TO DECOMPRESS A SPRING REMOVED FROM A VEHICLE.

1. To decompress the spring, reverse the compress procedure.

• Make sure you release the tension slowly to reduce the risk of the 

spring slipping/flying out.

MAINTAINING THE SPRING COMPRESSOR

• Before each use check the compressor to ensure it is not damaged 

or worn.

• If suspect, do not use the unit, but contact your local Clarke Dealer 

who will be able to advise you regarding repair and spare parts.

• Grease the compressor spindle as necessary to inhibit corrosion.

• Keep the compressor clean, and when not in use, store in a safe, 

dry, location.

WARNING: DO NOT COMPRESS THE SPRING TO AN EXTENT WHERE THE 
COIL WINDINGS OR JAWS TOUCH.

WARNING: DO NOT USED AIR TOOLS.
