proper torque level for your work.
CAUTION:
inserted straight in the screw head, or the screw
and/or driver bit may be damaged.
First, turn the adjusting ring so that the arrow on the tool
body points to the proper fastening torque level (1 - 21).
Place the point of the driver bit in the screw head and
apply pressure to the tool. Start the tool slowly and then
increase the speed gradually. Release the switch trigger
as soon as the clutch cuts in.
NOTE: When driving wood screw, pre-drill a pilot hole
2/3 the diameter of the screw. It makes driving easier
and prevents splitting of the workpiece.
