Rg. 12
When drilling hard smooth surfaces use a center punch
to mark desired hole location. This wili prevent the drili
bit from siipping off center as the hole is started. How
ever, the low speed feature allows starting holes without
center punching if desired. To accompiish this, simply
operate your 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.

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 materiai. If not -
prepared, this loss of control can result in
possible serious injury.
When drilling metais, 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.
