OPERATION
To remove bits,
lock the switch trigger and open the
chuck jaws.
The bit provided with the drill can be placed in the storage
area, located on the base of the drill.
ADJUSTING TORQUE
See Figure 10, page 10.
Rotate the adjustment ring to the proper torque setting for
the type of material and size of screw you are using.
• 1 - 4
For driving small screws
• 5 - 8
For driving screws into soft material
• 9 - 12
For driving screws into soft and hard
materials
• 13 - 16 For driving screws into hard wood
• 17 - 23 For driving large screws
•
For heavy drilling
DRILLING/DRIVING SCREWS
See Figures 11 - 12, page 10.
A level is located on the top of the motor housing to help
keep the drill bit level during use.
Check the direction of rotation selector for the correct
setting (forward or reverse).
Secure the workpiece in a vise or with clamps to keep it
from turning as the bit rotates.
Hold the drill firmly and place the bit at the point to be
drilled, or where the screw is to be driven.
WARNING
:
Do not drive a screw where there is likely to be hidden
wiring behind the surface. Contact with a “live” wire will
make exposed metal parts of the tool “live” and possibly
shock the operator. If you must drive a screw where
hidden wire may be present, always hold tool by insulated
gripping surfaces (handle) when performing the operation
to prevent a shock to the operator.
Depress the switch trigger to start the drill.
Move the bit into the workpiece, applying only enough
pressure to keep the bit cutting or driving the screw. Do
not force the drill or apply side pressure to elongate a
hole. Let the tool do the work.
WARNING
:
When drilling, 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.
With hard, smooth surfaces, use a center punch to mark
the desired hole location. This will prevent the bit from
slipping off-center as the hole is started.
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. Select drilling mode. 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
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.
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.
