Resumen del manual
1. Keep hose away from heat, oil and sharp 11. edges. Check hoses for wear and make certain that 12. all connections are secure. Read the entire Important Safety Information section at the beginning of this document including all text under subheadings therein before set up or use of this product. Save these instructions. Operating Instructions Measure the outer diameter of the spring to 1. be compressed and select the correct set of Shoes. Press down on the Release Valve Pedal (6) 2. releasing air pressure to lower the Under Strut Support until the Ram is fully retracted and the Under Strut Support (24) is at its lowest position.

The upper Shoe (28) should bear down on the first full coil down from the top of the strut. The lower Shoe should be pushing up on the first full coil up from the bottom of the strut. (See Fig. 2.) Measure the distance between these coils a. and adjust the position of the upper strut support so that the distance between the Shoes is slightly larger than required. Ensure that the Retaining Pins (30) holdb. ing the Upper Strut Support (31) are fully inserted and secured with the R-Clip (32) and Circlips (29) provided. Use the Foot Pedal (5) to raise the Under c. Strut Support (24) to finely adjust the distance between the Shoes. Before compressing, make a visual inspec4. tion of the tool to ensure all Retaining Pins are securely positioned and that there is no sign of wear or metal fatigue. If wear or fatigue is found, do not use the a. Tool. Have the tool replaced or repaired by a qualified technician. Fit the strut into the Shoes (28) and ensure 5. that the lower coil used lies behind the inner retaining rim at the back of the Shoe (28). Operate the Foot Pedal (5) to raise the upper coil end into contact with the upper spring seat, ensuring the coil at both ends are securely retained by the raised inner and outer rims within the Shoes (28, 28A). Wrap one Safety Chain (37) around the por6. tion of the spring and strut protruding from the upper Shoe (28) ensuring that the Chain lies above the Shoe. (See Fig. 2.) Wrap the other Safety Chain around the 7. spring and strut protruding from the lower Shoe ensuring that the Chain lies below the Shoe. Fasten each Chain behind the Upright (14) a. using the attached spring catches. Make sure each Chain is as tight as possible. Do not position the Chain in the coils held between the Shoes (28, 28A). When applying compression to the spring, 8. always stand to one side of the unit. Gradually compress the spring by pumping 9. the Foot Pedal (5) or operating the Air Valve (1) ensuring that the spring and strut remain securely held at all times. Ensure that the strut and the Upright (14) of 10. the compressor are correctly aligned at all times during spring compression. For conical springs, the center line of the a. spring should remain parallel to the compressor body. DANGER! Stop compressing the spring before the coil windings touch. You need only compress the spring until the upper spring seat is free from spring pressure. Before attempting to remove top cap nut on 11. the strut, use a tool or short stick to test if the spring compression has been relieved from the upper spring seat. Do not use your hands or fingers. Harbor Freight Tools recommends the use of 12. properly designed strut tools to remove the top cap nut from the shock absorber piston. Ensure that the shock absorber is supported a. as the top cap nut is removed to prevent it falling down through the coils and causing injury. Once compressed and the strut removed, it 13. is recommended to release the tension on the spring. Do not leave the spring under compression a. unattended and do not leave in compression for prolonged periods. I.e. overnight. Allow the spring to gradually decompress by 14. carefully pressing the Valve Release Pedal (6) keeping your hands and fingers away from the spring assembly. Replace the spring or shock absorber as 15. necessary and reassemble the strut by first compressing the spring and then introducing the shock absorber up through the lower Shoe (28) and compressed spring coils. Re-position the upper strut mount and sea. cure with the top cap nut. Before releasing the compression, ensure 16. that the top cap nut is securely tightened according to the manufacturer’s specs. Release the compression slowly keeping 17. your hands and fingers away from the spring assembly. Be sure that the spring ends are firmly and 18. securely seated in the upper and lower Shoes of the Compressor before removing the strut from the Spring Compressor. MAINTENANCE Before each use, check the compressor to 1. ensure it is not damaged or worn. If in any doubt DO NOT use the tool. Remove it from service immediately and a. have it replaced or repaired by a qualified technician. Refilling the hyd...
