Milwaukee 5426-21, 5446-21 manual Grounding Extension Cords, Assembly Functional Description

GROUNDING

EXTENSION CORDS

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

grounding system and must never be attached to an electrically “live” terminal.

Your tool must be plugged into an appropriate out- let, properly installed and grounded

in accordance with all codes and or- dinances. The plug and outlet should look like 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 insula- tion system which satisfies OSHA requirements and complies with the applicable standards of

Underwriters Laborato-
ries, Inc., the Canadian
Standard Association
and the National Elec-
trical Code. Double In-
sulated tools may be
used in either of the 120
volt outlets shown in Fig. B	Fig. C

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 “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.

WARNING To reduce the risk of injury, always use a side handle when using this tool. Always brace or hold securely.

Adjusting the Side Handle Position

1.Loosen the side handle by unscrewing the side handle grip (5426-21) or ball (5446-21) until the side handle rotates freely.

2.Rotate the side handle to the desired position.

3.Tighten the side handle grip or ball securely.

Moving the Side Handle (Cat. No. 5426-21)

1.Remove the side handle by unscrewing the side handle grip until it comes free.

2.Screw the side handle into the alternate loca- tion.

3.Tighten the side handle grip securely.

Setting the Depth Gauge

1.Press in the clamp lever.

2.Slide the depth gauge rod backward or forward until it is set for the desired depth.

Fig. 1 Drilling Depth

NOTE: The drilling depth is the distance be- tween the tip of the bit and the tip of the depth gauge rod.

3. Release the clamp lever.

WARNING To reduce the risk of in- jury, always unplug tool before changing or removing accessories. Only use accessories specifically recommended for this tool. Others may be hazardous.

Installing Drill Bits and Chisels

Be sure that the shank of the bit is clean. Dirt par- ticles may cause the bit to line up improperly. Do not use bits larger than the maximum recommended capacity of the drill because gear damage or mo- tor overloading may result. For best performance, be sure that the bit is properly sharpened and the shank is lightly greased before use.
