OPERATION

WARNING:

Always wear safety goggles or safety glasses with side

shields when operating tool. Failure to do so could result

in objects being thrown into your eyes, resulting in

possible serious injury.

DRILLING

See Figure 10.

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.

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 breakthrough. When these

situations occur, the drill has a tendency to grab and kick

in the opposite direction, 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.

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.
