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. 13).
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. Set the torque clutch to the drilling position.
3. Hold the drill firmly with both hands
whenever possible. Use one hand to grasp
the handle and switch end the other to to
grasp the body of the drill.
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.
4. While holding the drill firmly, place the point
of the drill bit at the point to be drilled.
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.
For safety reasons, the operator must
read the sections of this Owner’s Manual
entitled "GENERAL SAFETY
WARNINGS", "POWER TOOL SAFETY",
"SPECIFIC SAFETY RULES", "BATTERY
& CHARGER SAFETY" 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.
