DRILLING
See Figure 11.
OVERLOAD
Your drill has a built-in overload protector to protect the
motor during overloading or prolonged use. The overload
protector automatically
activates to break the circuit.
When this occurs, allow your drill to cool a few seconds
before resuming operation.
CHUCK
REMOVAL
See Figures 12, 13, and 14.
The chuck must be removed in order to use some
accessories. To remove:
•
Lock switch trigger or your drill by placing the direc-
tion of rotation selector in center position.
See Figure 2.
•
Insert a 5/16 inch or larger hex key wrench into the
chuck of your drill and tighten the chuck jaws securely.
•
Tap the hex key wrench sharply with a mallet in a
clockwise direction. See Figure 12. This will loosen
the screw in the chuck for easy removal.
Fig. 11
When drilling hard smooth surfaces use a center punch to
mark desired hole location. This will prevent the drill 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 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 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.
