OPERATION
WARNING:
Do not hold the chuck with one hand and use the power
of the drill to tighten the chuck jaws on the drill bit. The
chuck body could slip in your hand, or your hand could
slip and come in contact with the rotating drill bit. This
could cause an accident resulting in serious personal
injury.
MAG TRAy
™
(ScREW HOLDER)
See Figure 5, page 10.
The magnetic tray conveniently stores bits or other small
parts.
INSTALLING BITS
See Figures 6 - 7, page 11.
Lock the switch trigger by placing the direction of rotation
selector in the center position.
Open or close the chuck jaws to a point where the opening
is slightly larger than the bit size you intend to use. Also,
raise the front of the drill slightly to keep the bit from falling
out of the chuck jaws.
Insert the drill bit.
WARNING:
Make sure to insert the drill bit straight into the chuck
jaws. Do not insert the drill bit into the chuck jaws at an
angle then tighten, as shown in figure 7. This could cause
the drill bit to be thrown from the drill, resulting in possible
serious personal injury or damage to the chuck.
Tighten the chuck jaws securely on the bit.
NOTE: Rotate the chuck body in the direction of the
arrow marked
LOck to close the chuck jaws. Do not use
a wrench to tighten or loosen the chuck jaws.
REMOvING BITS
See Figure 6, page 11.
Lock the switch trigger by placing the direction of rotation
selector in the center position.
Open the chuck jaws.
NOTE: Rotate the chuck body in the direction of the arrow
marked
UNLOck to open the chuck jaws. Do not use a
wrench to tighten or loosen the chuck jaws.
Remove the drill bit.
DRILLING
Check the direction of rotation selector for the 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.
Hold the drill firmly and place the bit at the point to be
drilled.
Depress the switch trigger to start the drill.
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 tool 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.
NOTE: This drill has an electric brake. When the switch
trigger is released, the chuck stops turning. When the brake
is functioning properly, sparks will be visible through the
vent slots on the housing. This is normal and is the action
of the brake.
WOOD DRILLING
For maximum performance, use high speed steel bits for
wood drilling.
Begin drilling at a very low speed to prevent the bit from
slipping off the starting point. 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 DRILLING
For maximum performance, use high speed steel bits for
metal or steel drilling.
Begin drilling at a very low speed to prevent the bit from
slipping off the starting point.
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.
