Selecting Bits
When selecting a bit, use the right type for your
job. For best performance, always use sharp bits.
Drilling in Wood, Composition Materials and
Plastic
When drilling in wood, composition materials and
plastic, start the drill slowly, gradually increasing
speed as you drill. When using twist drill bits, pull
the bit out of the hole frequently to clear chips from
the bit fl utes. Use low speeds for plastics with a
low melting point.
Drilling in Masonry
When drilling in masonry, use high speed carbide-
tipped bits. Drilling soft masonry materials such as
cinder block requires little pressure. Hard materials
like concrete require more pressure. A smooth,
even fl ow of dust indicates the proper drilling rate.
Do not let the bit spin in the hole without cutting.
Do not use water to settle dust or to cool bit. Both
actions will damage the carbide.
Drilling in Metal
When drilling in metal, use high speed steel twist
drills or hole saws. Use slow speeds for hard metals
and high speeds for softer metals. Lubricate drill
bits with cutting oil when drilling in iron or steel. Use
a coolant when drilling in nonferrous metals such
as copper, brass or aluminum. Back the material
to prevent binding and distortion on breakthrough.
Driving Screws
When driving screws, use the proper screwdriver
bit for your job. After drilling pilot and shank holes,
start the screw slowly and increase the speed as
driving progresses. Set the screw by slowing to a
stop. Do not run screws down at excessive speeds.
To remove screws, reverse the motor.
WARNING
High rotational force. To
reduce the risk of injury, always hold or brace
securely. Always use side handle on tools
rated 1200 RPM or less.
Bit Binding
A high rotational force occurs when a bit binds. If
the bit binds, the tool will be forced in the opposite
direction of the bit rotation (See Fig. 11 - 13). Bits
may bind if they are misaligned or when they are
breaking through a hole. Wood boring bits can also
bind if they run into nails or knots. Be prepared for
bit binding situations.

To reduce the chance of bit binding:
• Use sharp bits. Sharp bits are less likely to bind
when drilling.
• Use the proper bit for the job. There are bits that
are designed for specifi c purposes.
• Use caution when drilling pitchy, knotty, wet or
warped material or when drilling in material that
may contain nails.

2. Remove worn brushes. If the brushes should fall
into the tool, be sure to shake them out before
reinserting the cartridge. Discard BOTH brushes.
Brushes should always be replaced in sets.
3. A set of spare brushes is provided in the car-
tridge. Remove the brushes from storage com-
partment.
4. Position new brushes with the fl at silver end fac-

MAINTENANCE

To reduce the risk of injury,
Maintaining Tools
Keep your tool in good repair by adopting a regula
maintenance program. Before use, examine the
general condition of your tool. Inspect guards
switches, tool cord set and extension cord fo
damage. Check for loose screws, misalignment
binding of moving parts, improper mounting, bro
ken parts and any other condition that may affec
its safe operation. If abnormal noise or vibration
occurs, turn the tool off immediately and have the
problem corrected before further use. Do not use a
damaged tool. Tag damaged tools "DO NOT USE
until repaired (see "Repairs").
Under normal conditions, relubrication is not neces

Cleaning
Clean dust and debris from vents. Keep the too
handles clean, dry and free of oil or grease. Use
only mild soap and a damp cloth to clean you

are harmful to plastics and other insulated parts
Some of these include: gasoline, turpentine, lacque
thinner, paint thinner, chlorinated cleaning solvents
ammonia and household detergents containing
ammonia. Never use fl ammable or combustible
solvents around tools.
Repairs
If your tool is damaged, return the entire tool to the
nearest service center.
always unplug the tool before attaching or
removing accessories. Use only specifi cally
recommended accessories. Others may be
hazardous.
