EXTENSION CORD PRECAUTIONS
WARNING! Keep the extension cord clear of the working area.
• Position the cord so it will not get caught on the workpiece, tools or any other obstructions while you are
working with the power tool.
• Make sure any extension cord used with this tool is in good condition. When using an extension cord, be
sure to use one of heavy enough gauge to carry the current the tool will draw. An undersized cord will cause
a drop in line voltage resulting in loss of power and overheating.
• The table bellow shows the correct size to use according to cord length and nameplate ampere rating. If in
doubt, use the next heavier gauge. The smaller the gauge number the heavier the cord.

Not Applicable
• Be sure your extension cord is properly wired and in good condition. Always replace a damaged extension
cord or have it repaired by a qualified electrician before using it. Protect your extension cord from sharp
objects, excessive heat and damp or wet areas.
• Use a separate electrical circuit for your power tools. This circuit must not be less than 14 gauge wire and
should be protected with either a 15 A time delayed fuse or circuit breaker. Before connecting the power
tool to the power source, make sure the switch is in the OFF position and the power source is the same as
indicated on the nameplate. Running at lower voltage will damage the motor.
SPECIFIC SAFETY PRECAUTIONS
WARNING! Know your impact drill. Read the Owner’s Manual carefully. Learn the tool’s applications and
limitations, as well as the specific potential hazards related to this tool. Following this rule will reduce the risk
of electric shock, fire or serious injury.
WARNING! Never use the drill in “impact” mode unless a proper masonry bit is installed and you
are drilling in concrete.
WARNING! Always use a safety shield, hearing protection and a dust mask when operating the drill
in “impact” mode.
• Do not drill material too small to be securely held.
• Always keep hands out of the path of the drill bit. Avoid awkward hand positions where a sudden slip could
cause your hand to move into the path of the drill bit.
• Make sure there are no nails or foreign objects in the part of the workpiece to be drilled.
• Do not install or use any drill bit that exceeds 7 in. (175 mm) in length or extends more than 6 in. (150 mm)
beyond the chuck jaws. They can suddenly bend or break.
• Before starting the operation, jog the drill switch to make sure the drill bit does not wobble or vibrate.
• Do not use fly cutters or multiple-part hole cutters, as they can come apart or become unbalanced in use.
• Make sure the spindle has come to a complete stop before touching the chuck or attempting to change the
drill bit.
• Always make sure the chuck is tight and the drill bit is firmly tightened in the chuck before starting the drill.
