• Remove adjusting keys or switches before turning the tool on.
A wrench or key that is left attached to a rotating part of the tool may
result in personal injury.
• Do not overreach. Keep proper footing and balance at all
times. Proper footing and balance enables better control of the tool
in unexpected situations.
• Use safety equipment. Always wear eye protection. Dust mask,
non-skid safety shoes, hard hat, or hearing protection must be used
for appropriate conditions.
TOOL USE AND CARE
• Use clamps or other practical way to secure and support the
workpiece to a stable platform. Holding the work by hand or
against your body is unstable and may lead to loss of control.
• Do not force tool. Use the correct tool for your application. The
correct tool will do the job better and safer at the rate for which it is
designed.
• Do not use tool if switch does not turn it on or off. Any tool that
cannot be controlled with the switch is dangerous and must be
repaired.
• Disconnect the plug from the power source before making any
adjustments, changing accessories, or storing the tool. Such
preventative safety measures reduce the risk of starting the tool
accidentally.
• Store idle tools out of reach of children and other untrained
persons. Tools are dangerous in the hands of untrained users.
• Maintain tools with care. Keep cutting tools sharp and clean.
Properly maintained tools, with sharp cutting edges are less likely to
bind and are easier to control.
• Check for misalignment or binding of moving parts, breakage
of parts, and any other condition that may affect the tools
operation. If damaged, have the tool serviced before using.
Many accidents are caused by poorly maintained tools.
• Use only accessories that are recommended by the
manufacturer for your model. Accessories that may be suitable
for one tool, may become hazardous when used on another tool.

TURN OFF TOOL AND DISCONNECT FROM POWER SUPPLY.
Be sure your power supply agrees with nameplate marking. 120 V
AC/DC means the tool may be operated with alternating or direct
current within at a voltage of 120 V.
220/240V AC/DC means the tool may be operated with alternating or
direct current within a voltage range of 220 to 240 volts.
Voltage decrease of more than 10% will cause loss of power and
overheating. All tools are factory tested; if this tool does not operate,
check the power supply.
Operation
DRILLING
1. Always unplug the drill when attaching or changing bits or
accessories.
2. Use sharp drill bits only. For WOOD, use twist drill bits, spade bits,
power auger bits, or hole saws. For METAL, use high speed steel
twist drill bits or hole saws. For MASONRY, such as brick, cement,
cinder block, etc., use carbide-tipped bits.
3. Be sure the material to be drilled is anchored or clamped firmly. If
drilling thin material, use a wood "back-up" block to prevent
damage to the material.
4. Always apply pressure in a straight line with the bit. Use enough
pressure to keep drill biting, but do not push hard enough to stall
the motor or deflect the bit.
