OPERATION
WARNING:
Always wear safety goggles or safety glasses with side shields when operating tool. Failure to do so could result in dust, shavings, or loose particles being thrown into your eyes, resulting in possible serious injury.
DRILLING
See Figure 15.
The material to be drilled should be secured in a vise or with clamps to keep it from turning as the drill bit rotates.
Hold tool firmly and place the bit at the point to be drilled. Depress the switch trigger to start tool.
Move the drill bit into the workpiece, applying only enough pressure to keep the bit cutting. Do not force or apply side pressure to elongate a hole.
We recommend that you select normal drill mode when drilling with twist drills, hole saws, etc., in soft material.
WARNING:
Do not force tool. Forcing tool can result in jamming and loss of balance or footing, which could result in personal injury.
When drilling hard, smooth surfaces, use a center punch to mark the desired hole location. This will prevent the drill bit from slipping off center as the hole is started. However, the lower speed feature allows starting holes without center punching if desired. To accomplish this, simply operate your drill at lower speed until the hole is started.
For drilling in wood, begin drilling at LO (1) speed, gradu- ally increasing to full power. Occasionally clear chips from the bit to prevent overheating. Low speed bits should be used when drilling larger holes.
When drilling metals other than brass and cast iron, use a light oil on the drill bit to keep it from overheating. The oil will prolong the life of the bit and increase the drilling action. Begin drilling at LO (1) speed, gradually increasing to higher speeds. When drilling larger holes in steel, it may be helpful to first drill a smaller pilot hole.
We recommend that you use

For using the hammer drill feature, rotate the torque adjustment ring, as shown in figure 4, so that the hammer symbol is aligned with the arrow. Using the auxiliary handle will provide better control and prevent forcing the tool.
Fig. 15
■Hold the drill at a right angle as shown in figure 15. Do not force or apply side pressure to elongate the hole.
■If the hammer speed decreases while drilling deep holes, it may be necessary to lift up partially on the tool to clear debris from the hole.
■If there is excessive dust while using the hammer feature, do not add water to the hole. This can cause clogging and binding of the bit.
■If the bit jams in workpiece or if the drill stalls, release switch trigger immediately. Remove the bit from the workpiece and determine the reason for jamming.
WARNING:
Be prepared for binding or bit breakthrough. When these situations occur, the drill has a tendency to grab and kick opposite to the direction of rotation, and could cause loss of control when breaking through material. If you are not prepared, this loss of control can result in possible serious injury.
