OPERATION

WARNING:

Make sure to insert drill bit straight into chuck jaws. Do not insert drill bit into chuck jaws at an angle and then tighten, as shown in Figure 5. This could cause drill bit to be thrown from drill, resulting in possible serious personal injury or damage to the chuck.

REMOVING BITS

See Figure 4.

■Unplug your drill.

WARNING:

Failure to unplug your drill could result in accidental starting causing serious injury.

■Loosen the chuck jaws from drill bit.

■To loosen: grasp and hold the collar with one hand, while rotating chuck body with your other hand.

Note: Rotate chuck body in the direction of the arrow marked UNLOCK to loosen chuck jaws.

■Do not use a wrench to tighten or loosen the chuck jaws.

■Remove drill bit from chuck jaws.

WARNING:

Always wear safety goggles or safety glasses with side shields when operating your drill. Failure to do so could result in dust, shavings, loose particles or foreign objects being thrown into your eyes, causing possible serious injury.

DRILLING

See Figure 6.

When drilling hard smooth surfaces use a center punch to mark desired hole location. This will prevent the drill bit from slipping off center as the hole is started. How- ever, the low speed feature allows starting holes with- out center punching if desired. To accomplish this, sim- ply operate your drill at a low speed until the hole is started.

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.

WARNING:

Be prepared for binding or bit breakthrough. When these situations occur, 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 not prepared, this loss of control can result in possible serious injury.

When drilling metals, 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.

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.
