Refit and tighten the air cylinder cap.
2. Adjusting the stroke:
Check that the hydraulic level is correct.
Remove the frame head using the spanner provided.
Check the jaw stroke by using the supplied spanner/gauge as in fig. 3.
If necessary, adjust the stroke as follows:
1) Hold the rear jaw case (fig. 3.2) with the larger spanner and loosen the lock nut
(fig. 3.1) with the spanner/gauge.
2) Adjust the stroke by rotating the jaw case assembly and tighten the lock nut when
adjustment is complete.
Refit the frame head.
3. Changing jaws:
Disconnect the tool from the air line.
Remove the frame head using the spanner provided.
Use both spanners to unscrew the front jaw case (fig. 3.3) from the rear jaw case (fig.
3.2).
Remove the jaws (fig. 3.4) and clean with solvent and brush. If the teeth are blunted,
replace with new jaws.
Reverse the above procedure to reassemble.
4. Operation:
DANGER! Always fit the safety cap (fig. 1.C) to the rear of the frame before use to
prevent injury from ejected rivet stems fit with the slot facing downwards so that stems
fall to the floor.
Select the nosepiece to suit the rivet size and fit to the frame head using the spanner
provided.
Insert the rivet stem fully through the nosepiece and thus into the jaws.
Press the rivet body through the pre-drilled hole and hold with the rivet flange flush on
the workpiece.
Squeeze the trigger. The rivet will be compressed and the rivet stem will be ejected into
the safety cap.
