Sealey RE231 - Manual (Page 3)

5.6. Air line hook up for Model No RE232.V3
5.6.1. ensure the air supply valve (fig.4c) is in the "off" position before connecting to the air supply. the spring compresser requires a
maximum air pressure of 120psi (8.3bar) to operate at full capacity.
 WARNING! Ensure air supply is clean and does not exceed 120psi (8.3bar). Too high an air pressure and unclean air will
shorten the life of the unit due to excessive wear, and may be dangerous causing possible damage and/or personal injury.
5.6.2. drain the air supply tank daily and clean the air inlet filter screen weekly.
5.6.3. for recommended hook-up, see diagram.
5.6.4. line pressure should be increased to compensate for unusually long air hoses (over 8 metres).
5.6.5. Keep hose away from heat, oil and sharp edges. check hoses for wear and make certain that all connections are secure.
6.1. Measure the outer diameter of the spring to be compressed and select the correct set of yokes. fit the yokes as described in section 5.4.
6.2. operate the release valve pedal (fig.4B) and press down on the lower strut support until the piston is full retracted.
6.3. the upper yoke should bear down on the first full coil down from the top of the strut. the lower yoke should be pushing up on the first full
coil up from the bottom of the strut. Measure the distance between these coils and adjust the position of the upper strut support so that the
distance between the yokes is slightly larger than required. ensure that the pins fixing the upper support are fully inserted and retained with
the spring clips provided. use the foot pedal (fig.4A) to raise the lower yoke/strut support to finely adjust the distance between the yokes.
6.4. 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.
6.5. 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.
6.6. Wrap one safety chain around the portion of the spring and strut protruding from the upper yoke ensuring that the chain lies above the
yoke. Wrap the other chain around the spring and strut protruding from the lower yoke ensuring that the chain lies below the yoke.
fasten each chain behind the main pillar using the sprung catches attached. Make sure each chain is as tight as possible. DO NOT
position the chain between the coils held between the yokes.
6.7. When applying compression to the spring, always stand to one side of the unit.
6.8. Gradually compress the spring by pumping the foot pedal or operating the air valve (re232.V3) 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.
6.9. 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.
6.10. 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. i.e. overnight.
