4. CONVERTION PROCEDURE
4.1
First remove both strut support brackets from the existing unit.
UPPER BRACKET(Fig.3): Remove the 'R' clips 'E' & 'G' from the two long pins
which hold the bracket in place. Support the bracket and its adjustable jaws
and remove the two pins 'D' & 'F'. Slide the bracket up and off the main pillar.
Retain the two clips and the two long pins for use with the new bracket.
LOWER BRACKET(Fig.4): The lower strut support bracket is attached to the
top of the ram with a grub screw which passes through a saddle mounted on
a pin in the back of the bracket. Remove the grub screw 'Z' and slide the
bracket up and off the main pillar.
4.2
The new lower strut support already has a pin mounted saddle fitted
within it. Slide the new lower strut support over the main pillar (see 'X' in
Fig.5) until the top of the ram passes into the saddle. Once you are sure
that the top of the ram has passed fully into the saddle tighten the grub
screw mounted in the side of the saddle (see 'A' in Fig.5).
4.3
Slide the new upper strut support 'Y' over the main pillar to the required
height and align the two holes in the support with two holes in the pillar.
Slide the two long pins (see D & F in Fig.6) through the assembly and
retain them in position using the 'R' clips (see E & G in Fig.6).
4.4
Two pairs of support jaws are supplied, one large pair and one small pair.
To fit either pair of jaws see Fig.7. Hold the chosen jaw in place within each
support bracket and slide the connecting pin 'K' back into place and retain it
with the 'R' clip. Replace the socket cap bolt 'J'. The jaws are designed to be
used as matched pairs and should not be mixed.
4.5
The converted unit must now be fixed securely to the ground in order to ensure the safety of the user.
Holes are to be found in the brackets, which allow the unit to be secured by way of masonry bolts or sinking pins into
concrete.
WARNING! Whichever method is used, ensure the unit is adequately fixed and cannot topple.

5. INSTRUCTIONS FOR USE
5.1
Measure the outer diameter of the spring to be compressed and select the correct set of jaws. Fit the jaws as described in
para.4.4.
5.2
Operate the release valve pedal (fig.8-B) and press down on the lower strut support until the piston is full retracted.
5.3
The upper jaw should bear down on the first full coil down from the top of the strut. The lower jaw 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 jaws 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.8-A) to raise the lower jaw/strut
support to finely adjust the distance between the jaws.
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 jaws and ensure that the lower coil used lies behind the retaining rim at the back of the jaw. Operate
the foot pedal to raise the upper coil used into contact with the upper jaw ensuring once again that the coil is retained by
the raised rim within the jaw.
5.6
Wrap a safety chain around the portion of the spring and strut protruding from the upper jaw ensuring that the chain
lies above the jaw. Wrap another chain around the spring and strut protruding from the lower jaw ensuring that the
chain lies below the jaw. 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 jaws.
5.7
When applying compression to the spring, always stand to one side of the unit and keep hands and fingers away from the
assembly during compession.
