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).
