position by the tool alignment bolt, and the tool body. tighten the alignment bolt securely against chain to hold chain in place.
4.1.5.

the alignment bolt until the pin has been pushed through the link,ensure that an equal length of pin shows on each side of the link
4.2.3.
Position the tool over the pin to be riveted, make sure rivet tip is withdrawn 2mm into the alignment bolt and tighten the alignment
bolt securely against chain. Tighten the push (extractor) bolt so that the rivet tip flares the chain pin. Both ends of the chain link pin
should be flared so the pin is securely held in place. Repeat procedure on other link pin.

Withdraw the tool, from the chain; visually check that both chain link pins show the same flared ends and that the rivets on the side
plates are in alignment with side plates on either side.
note: You may also use the press plates to flare the ends of pins as shown below (fig.4); use the press plate with the two holes
in the upper jaw and the grooved press plate in the lower jaw. You may also use a combination of the rivet pin and lower press plate
as fig.5.
