above, then use the “DEPTH OF DRIVE ADJUSTMENT” to give the desired depth of drive.
TO ADJUST “DEPTH OF DRIVE ADJUSTMENT” :
1. With air pressure set, drive a few fasteners into a representative material sample to determine if adjustment is necessary.
2. If adjustment is required, disconnect the air supply.
3. Refer to label on the outside of door for direction to turn adjusting nut. (See illustration)
4. Remove the cover mounting nuts, cover, and adapter. Observe the orientation of the flats on the adjusting nut. Rotate
the adjusting nut to the left to increase fastener drive depth, or to the right to decrease it. Reorient the flats to be same
as before. Reinstall adapter, cover, and mounting nuts.
5. Before reconnecting the air supply, check that the trip mechanism parts operate freely with no binding or sticking.
