EXTEnSiOn COrDS
grounded tools require a three wire extension cord. Double insulated tools can use either a two or three wire extension cord. As the
distance from the power supply outlet increases, you must use a heavier gauge extension cord. using extension cords with inadequately sized wire
causes a serious drop in voltage, resulting in loss of power and possible tool damage. Refer to the table shown below to determine the required
minimum wire size.
The smaller the gauge number of the wire, the greater the capacity of the cord. for example: a 14-gauge cord can carry a higher current than a 16-
gauge cord. When using more than one extension cord to make up the total length, be sure each cord contains at least the minimum wire size required.
If you are using one extension cord for more than one tool, add the nameplate amperes and use the sum to determine the required minimum wire size.
Guidelines for Using Extension Cords
•
If you are using an extension cord outdoors, be sure it is marked with the suffix "W-A" ("W" in Canada) to indicate that it is acceptable for outdoor use.
• Be sure your extension cord is properly wired and in good electrical condition. Always replace a damaged extension cord or have it repaired by a
qualified person before using it.
• Protect your extension cords from sharp objects, excessive heat, and damp or wet areas.

SPECiFiC SAFETY rULES FOr HAMMEr DriLLS
WArning:
DO nOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to the hammer drill
safety rules. if you use this tool unsafely or incorrectly, you can suffer serious personal injury.
1. Hold the tool by insulated gripping surfaces when performing an operation where the cutting tool may contact
hidden wiring or its own cord. Contact with a "live" wire will make exposed metal parts of the tool "live" and shock the operator. Do not
drill, fasten or break into existing walls or other blind areas where electrical wiring may exist. If this situation is unavoidable, disconnect all fuses or
circuit breakers feeding this worksite.
2. Always use safety glasses or goggles. Ordinary eye or sun glasses are nOT safety glasses. uSe CeRTIfIeD SAfeTY
eQuIPMeNT. Protective eyewear should comply with ANSI Z87.1 standards. use a dust mask or respirator for operations which generate dust.
3. Wear ear/hearing protectors when using this tool for extended periods. Prolonged exposure to high intensity noise can cause
hearing loss.
4. Hold the tool firmly with both hands. Always use the auxiliary handle to prevent injury that may result from loss of control because of
high rotational force.
5. Always be sure you have firm footing and check to see no one is below when using the tool in high locations.
