OPERATION
INSTALLING DEPTH GAGE ROD
See Figures 11 and 12.
A depth gage rod has been packed with your hammer drill to assist you in controlling the depth of drilled holes.
When drilling holes with the depth gage rod installed, the desired hole depth has been reached when the end of the rod comes in contact with the surface of the material being drilled.
Follow these steps to install and adjust the depth gage rod.
1.Loosen the auxiliary handle.
2.Insert the depth gage rod through hole on the auxiliary handle.
3.Adjust the depth gage rod so that the drill bit extends beyond the end of the rod to the required drilling depth.
4.Tighten the auxiliary handle securely. This secures the depth gage rod at the desired depth of cut. It also secures the auxiliary handle.

This drill is equipped with an adjustable torque clutch for driving different types of screws into different materials. The proper setting depends on the type of material and the size of screw you are using.
TO ADJUST TORQUE
Identify the twenty four torque indicator settings located on the front of the drill. See Figure 13.
