•Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
•Maintain labels and nameplates. These carry important information. If unreadable or missing, contact a MILWAUKEE service facility for a free replacement.
•WARNING Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
•lead from
•crystalline silica from bricks and cement and other masonry products, and
•arsenic and chromium from
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are spe- cially designed to filter out microscopic particles.

GROUNDING
WARNING Improperly connecting the grounding wire can result in the risk of elec- tric shock. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. Do not modify the plug provided with the tool. Never remove the grounding prong from the plug. Do not use the tool if the cord or plug is damaged. If damaged, have it repaired by a MILWAUKEE service facility before use. If the plug will not fit the outlet, have a proper outlet installed by a qualified electrician.
Grounded Tools: Tools with Three Prong Plugs Tools marked “Grounding Required” have a three wire cord and three prong grounding plug. The plug must be connected to a properly grounded outlet (See Figure A). If the tool should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user, reducing the risk of electric shock.
The grounding prong in the plug is connected through the green wire inside the cord to the grounding system in the tool. The green wire in the cord must be the only wire connected to the tool's grounding system and must never be attached to an electrically “live” terminal.
Your tool must be plugged into an ap- propriate outlet, properly installed and
grounded in accordance with |
|
all codes and ordinances. The |
|
plug and outlet should look like | Fig. A |
those in Figure A. |
Double Insulated Tools: Tools with Two Prong Plugs
Tools marked “Double Insulated” do not require grounding. They have a special double insulation system which satisfies OSHA requirements and complies with the applicable
standards of Underwriters Laboratories, Inc., the Ca- nadian Standard Associa- tion and the National Electri- cal Code. Double Insulated tools may be used in either of
the 120 volt outlets shown in Fig. B Fig. C Figures B and C.

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 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 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
•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.

ASSEMBLY
WARNING To reduce the risk of injury, always unplug tool before attaching or remov- ing accessories or making adjustments. Use only specifically recommended accessories. Others may be hazardous.
WARNING To reduce the risk of injury, do not grasp the bit while the chuck is rotat- ing or while the bit is falling from the chuck.
Installing Bits into Keyless Chucks
These tools are equipped with a
keyless chuck. Always unplug the tool before install- | ||
ing or removing bits. |
| |
1.To open the chuck jaws, |
| |
turn the sleeve counter- |
| |
clockwise. |
| |
When using drill bits, allow |
| |
the bit to strike the bottom |
| |
of the chuck. Center the |
| |
bit in the chuck jaws and Sleeve | Collar | |
lift it about 1/16" off of the | ||
| ||
bottom. |
| |
When using screwdriver bits, insert the bit far enough for the chuck jaws to grip the hex of the bit.
2.To close the chuck jaws, hold the collar while turning the sleeve clockwise. Tighten securely.
WARNING To reduce the risk of injury, wear safety goggles or glasses with side shields.
Chuck Removal
This tool is equipped with a threaded spindle to hold the chuck. Before removing the chuck, unplug the tool and open the chuck jaws. A
remove the chuck, hold
the tool so that only the 
side of the chuck rests firmly and squarely on a
solid workbench. Insert the chuck key or a chuck remover bar in one of the keyholes. Turn the chuck so the key is at about a
30° angle to the bench top and strike the key
sharply with a hammer so the chuck turns in a counterclockwise direction (looking from the front of the tool). This should loosen the chuck from the spindle which has a right hand thread making it easy to remove the chuck by hand.
NOTE: When replacing the chuck, always replace the left hand thread screw in the chuck.
