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 12.
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 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.
