5.4.
Before commencing compression, make a visual inspection of machine to ensure pins are securely positioned and that there is no sign of
wear or fatigue; if found, DO NOT use the unit and refer to your local Sealey dealer for advice and replacement parts.
5.5.
Insert the strut into the yokes and ensure that the lower coil used lies behind the retaining rim at the back of the yokes. Operate the foot
pedal to raise the upper coil into contact with the upper yoke ensuring once again that the coil is retained by the raised rim within the yoke.

5.6.
Attach the safety chains to the spring at top and bottom of the coil and fix the loose end back onto the chain using the clip. Take care not
to nip the safety chain between the closed spring coils.
5.7.
When applying compression to the spring, always stand to one side of the unit.
5.8.
Gradually compress the spring by pumping the foot pedal, ensuring that the spring and strut remain securely held at all times. Ensure that
the strut and the body of the compressor are correctly aligned at all times during spring compression. For conical springs, the centre line of
the 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 strut top plate is
free from the spring. The pressure applied may be monitored by observing the gauge mounted in the top of the mast.
5.9.
Before attempting to remove top cap nut, always use a tool or short stick to test if the spring compression has been relieved from the
top plate. DO NOT use your hands / fingers. Sealey recommends the use of purpose made strut tools to remove the top-nut from the
shock piston. Ensure that the shock absorber is supported as the top nut is undone to prevent it falling down through the coils and
causing injury.
5.10. Once compressed, and the strut removed, we recommend releasing the tension on the spring. DO NOT leave the spring under
compression in the machine unattended and do not leave in compression for prolonged periods, for instance overnight.
5.11. Allow the spring to gradually decompress by carefully operating the valve release pedal keeping your hands and fingers away from the
spring assembly. Monitor the release of pressure by means of the pressure gauge.
5.12. Replace the spring or shock absorber as necessary and reassemble the strut by first compressing the spring and then introducing the
shock absorber up through the lower yoke and compressed spring coils. Reattach the top plate and top nut, making sure that the ends sit
correctly in the strut and strut cap.
5.13. Before releasing the compression ensure that the top strut nut is securely fastened to the maker's tolerance.
5.14. Release the compression slowly keeping your hands and fingers away from the spring assembly.
5.15. Be sure that the tension on the spring is fully controlled by the strut assembly before removing it from the yokes of the compressor.
6. MAINTENANCE
6.1.
Before each use, check the compressor to ensure it is not damaged or worn. If in any doubt DO NOT use the unit. Remove it from
service immediately and contact your local Sealey dealer for advice/repairs.
6.2.
Refilling the hydraulic system with oil is rarely necessary but the level should be checked in the event of a loss of performance. To
check oil level, ensure the ram is fully lowered, remove filler plug and check that level is within 10mm of filler hole. Add hydraulic jack oil
if necessary. NOTE: Use a good quality jack oil, such as SEALEY HYDRAULIC JACK OIL.
WARNING: DO NOT use brake fluid, or any fluid other than hydraulic jack oil as this will cause serious damage and will invalidate the
warranty
