3.Set the speed by adjusting the Variable Speed Switch (5) to either 1 (low) or 2 (high). High speed is generally used for drilling applications and low speed is generally used for screw driving applications. See FIGURE 5.

4.	Set the Torque by aligning the desired Torque	Torque Indicator Arrow Hammer Icon
	setting with the Torque Indicator Arrow. See
	FIGURE 5. There are seven Torque setting
	icons. They range from low driving settings,	Variable Speed Switch (5)
	to drill settings, to the impact or hammer drill
	setting. When using the Hammer Drill set-		Driver Icons

	Indicator Arrow as shown in FIGURE 5.
	When using the Hammer Drill as a driver, use
	the Driver Icons, also shown. The Drill Icon
	is not shown in figure 5 but looks like a drill
	bit. Higher torque settings (Drill Icon or Ham-
	mer) will break the heads off of screws. Only		FIGURE 5

	counterclockwise, you are in the reverse po-
	sition (to remove a screw or help pull a bit	6	26.6-53.1

	Switch (6) to change direction. Do not use
	the Reverse Switch (6) when the drill is rotating.

7.After the workpiece is secure, use an awl (not included) to punch a starter hole for the drill bit. Place the bit on the workpiece prior to starting the Hammer Drill. Holding the Hammer Drill with both hands, gently squeeze the Trigger (16) increasing your tension on the Trigger (16) after you are sure the bit is securely in the pilot hole. After complet- ing the task, stop the Hammer Drill, reverse the direction of the drill (see number 6 above), and gently squeeze the Trigger (6) as you back out the drill.
