Clutch Torque Setting
Test the setting before actual operation.
Adjust the torque to one of the five clutch settings for
driving fasteners, the drill setting
for screw
fastening and drilling operations, or the rotation with
hammering setting
for concrete and block drilling.
The lower clutch settings deliver less torque than the
higher clutch settings. During operation a ratcheting
sound may be heard; release the trigger. This sound
indicates that the clutch is slipping because the driving
operation has overcome the available torque for the
engaged clutch setting.
For operations that require higher torque, use the low
speed setting.

Drilling holes in wood and metal
(A) For fastening screws into plastic anchor, which requires dia. 1/4" (6 mm) prehole in concrete.
(B) For directly fastening screws into concrete (i.e., Tapcon) with dia. 1/8" (3.5 mm) prehole.
Note: This is only a rough guide. Required torque is different depending on the shape, material, and application of
the screws. Set according to the work environment of the site.
