,_ 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.
DRILLING
See Figure 10.
,_ 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.
When drilling hard smooth surfaces use a center punch to
mark desired hole location. This will prevent the ddtl bit from
slipping off center as the hole is started. However, the low
speed feature allows starting holes without center punching if
desired. To accomplish this, simply operate the 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.
