Adjusting Locator Assembly
The locator assembly controls the tool's driving
depth. These screwdrivers feature a locator assembly
with one-handed depth adjustment. Depth adjust-
ments can be made easily and quickly by turning
the locator with one hand. Detents inside the sleeve
“lock” the selected depth.
For the drywall ramp-off locator assembly, start with
about 1/16" clearance between the head of the screw
and nose with the snap-action clutch disengaged
as shown.
For both locator assemblies, the
1/16"
detents on the inside of the
sleeve represent different
depths. Every two clicks of the
locator equal 1/64". Continue
adjusting the locator to the
desired depth.
1. To increase the driving
depth, simply rotate the loca-
tor in the direction labeled .
2. To decrease the driving
depth, simply rotate the loca-
tor in the direction labeled .
The detents “lock” the locator
in place, ensuring an accurate depth setting.
3. To remove the locator assembly, turn the ramp-off
sleeve while pulling it away from the tool. Reat-
taching the locator assembly will not change the
depth setting.
