Adjusting the driving depth of screws

The depth to which a screw is driven into the wall or other surface can be accurately set to suit the type of screw and the material being fastened. It’s possible to drive screws so that they are raised, flush or countersunk into the material.

The driving depth is adjusted with the adjustment collar (3).

Turn the adjustment collar (3) to approximately the correct setting.

(Take care not to over tighten the adjustment collar so that the graduated markings on the nose cone are completely covered).

Drive a test screw into a piece of scrap material.To increase the depth of the head of the screw below the surface of the material, turn the adjustment collar (3) clockwise so that the end of the bit extends further from the end of the nose cone.

To decrease the depth of the screw, turn the adjustment collar (3) anti-clockwise so that the end of the bit is closer to the end of the nose cone.

WARNING. Do not over tighten the adjustment collar (keep within the graduated markings on the nose cone) as it can cause the nose cone to jam.

If the adjustment collar (3) is overtightened and jams, pull on the nose cone (1) and turn the collar (3) to re-engage the thread.

Operation

Install the bit tip in the bit holder.

Adjust the driving depth with the adjustment collar (3).

Check that the tool is set for forward or reverse rotation as desired.

When driving, place the screw on the bit, operate the trigger switch and apply pressure to the tool.

Drive the screw until the nose cone contacts the work surface at which time the clutch will disengage and the driving action will stop.

When removing screws and other fasteners, make sure that the adjustment collar (3) is all the

way towards the nose piece and that the forward/reverse switch (6) is positioned on the left-hand side of the tool (as viewed from the rear).
