DRILLING
See Figure 8, page 12.
Depress and release the switch trigger to be sure the drill
is in the
OFF
position before connecting it to power supply.
Check the direction of rotation selector for correct setting
(forward or reverse).
Secure the material to be drilled in a vise or with clamps
to keep it from turning as the drill bit rotates.
Install auxiliary handle.
Plug the drill into power supply source.
Hold the drill firmly and place the bit at the point to be
drilled.
Depress the switch trigger to start the drill. Do not lock
the switch
ON
for jobs where the drill may need to be
stopped suddenly.
Move the drill bit into the workpiece applying only enough
pressure to keep the bit cutting. Do not force the drill or
apply side pressure to elongate a hole. Let the drill and
bit do the work.
WARNING:
Be prepared for binding at 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 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.
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 the workpiece or if the drill stalls, stop
the tool immediately. Remove the bit from the workpiece
and determine the reason for jamming.
WOOD AND METAL DRILLING
For maximum performance, use high speed steel bits for
wood or metal drilling. Begin drilling at a very low speed to
prevent the bit from slipping off the starting point.
Wood drilling:
Increase the speed as the drill bit bites into the material.
When drilling through holes, place a block of wood behind
the workpiece to prevent ragged or splintered edges on
the back side of the hole.
Metal and steel drilling:
Maintain a speed and pressure which allows cutting
without overheating the bit. Applying too much pressure
will:
• Overheat the drill;
• Wear the bearings;
• Bend or burn bits; and
• Produce off-center or irregular-shaped holes.
When drilling large holes in metal, start with a small bit,
then finish with a larger bit. Also, lubricate the bit with oil
to improve drilling action and increase bit life.
OPERATION
CALIFORNIA PROPOSITION 65
WARNING:
This product and some dust created by power sanding, sawing, grinding, drilling, and other construction activities may
contain chemicals, including lead, known to the State of California to cause cancer, birth defects, or other reproductive
harm.
Wash hands after handling.
Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products and,
• arsenic and chromium from chemically treated lumber.
Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your
exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially
designed to filter out microscopic particles.
