DRILLING
When drilling into smooth, hard surfaces
such as metal, 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.
The workpiece to be drilled should be
secured in a vice or with clamps to keep it
from turning as the drill bit rotates (Fig. 6).
1.
Check the drill bit to make sure it is
firmly locked into the drill chuck, and
verify that the forward/reverse switch is
in the forward position.
2. Hold the drill firmly with both hands
whenever possible. Use one hand to
grasp the handle and switch.
NOTE:
Make sure the hand placed on
the body of the drill does not cover the
air vents. Covering these air vents will
reduce motor cooling, and possibly lead
to overheating the motor.
3. While holding the drill firmly, place the
point of the drill bit at the point to be
drilled.
4. Squeeze the switch trigger to start the drill.
NOTE:
Always use a higher drill speed
when drilling small holes. Use a slower
drill speed when drilling large holes.
5. Move the drill bit into the workpiece
applying only enough pressure to keep
the bit cutting. Do not force the drill bit
or apply sideways pressure to elongate
the hole.
WARNING: Be prepared for binding and
bit breakthrough. When these situations
occur, the drill bit has a tendency to grab
the workpiece. This action will kick the
drill opposite to the direction of the drill
bit rotation, and could cause loss of control
when breaking through material as you
complete drilling the hole. If you are not
prepared, this loss of control can result in
serious injury.
When drilling metals, use light oil on the
drill bit to keep it from overheating. The
oil will prolong the life of the drill bit and
improve the cutting action. If the bit jams
in the workpiece, or if the drill stalls, release
the trigger switch immediately. Remove the
bit from the workpiece and determine the
reason for jamming.
ASSEMBLY AND OPERATING
(continued)
WARNING:
For safety reasons, the operator must
read the sections of this Owner’s Manual
entitled "GENERAL SAFETY WARNINGS",
"POWER TOOL SAFETY", "SPECIFIC
SAFETY RULES", "GUIDELINES FOR
EXTENSION CORDS" and "SYMBOLS"
before using this drill.
Verify the following every time the drill
is used:
1.
Safety glasses, safety goggles, or
face shield is being worn.
2.
Hearing protection and dust mask
are being worn when drilling in
concrete.
3.
The chuck has not worked loose on
the spindle.
4.
The bit is in good condition, and is
properly tightened into the chuck.
Failure to observe these safety rules will
significantly increase the risk of injury.
