WARNING:
Always wear safety goggles or safety
glasses with side shields when operating tools.
Failure to do so could result in objects being thrown
into your eyes, resulting in possible serious injury.

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.
This drill has an electric brake. When the trigger switch is
released, the chuck stops turning. When the brake is
functioning properly, sparks wilt be visible through the vent
slots on the housing. This is normal and is the action of
the brake.
Fig. 8
When drilling hard smooth surfaces use a center punch to
markthe desired hole location. This will prevent the drill bit
from slipping off center as 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 the tool firmly and place the bit at the point to be
drilled. Depress the switch trigger to start the toot.
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.
