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 11.
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. How-
ever, 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 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.
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.
