GROUNDING

EXTENSION CORDS

Speciﬁcations

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

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

ASSEMBLY

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 appropriate out- let, properly installed and grounded in accordance with all codes and ordinances.

The plug and outlet should look like those in Figure A.

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 unplug tool before attaching or remov- ing accessories or making adjustments. Use only speciﬁcally recommended accessories. Others may be hazardous.

Blades and Blade Selection

The blade dimensions required for the band saws are: .020" thickness, 1/2" width and 44-7/8" in length. The special .020" thickness reduces ﬂexure fatigue and provides maximum tooth life. To maxi- mize cutting life, use a blade with the correct pitch (teeth per inch) for the speciﬁc cutting job.

Blades are available in several pitches. To select the proper blade, three factors should be considered: The size, shape, and type of material to be cut.

The following suggestions are for selecting the right blade for various cutting operations. Keep in mind that these are broad guidelines and that blade requirements may vary depending upon the speciﬁc size, shape and type of material to be cut. Gener- ally, soft materials require coarse pitch blades and hard materials require ﬁne pitch blades. Use coarse pitch blades for thick work and ﬁne pitch blades for thin work. It is important to keep at least three teeth in the cut (see "Typical Application").

Changing Blades

1.UNPLUG THE TOOL BEFORE REMOVING OR INSTALLING BLADES.

2.Turn the tension lock handle located on the front of the saw 180° counterclockwise. This releases the tension on the blade for easy removal.

3.Remove the blades from the pulley ﬁrst and then from the guides.

4.To install a new blade, with the pulleys facing up, insert the blade between the rollers and the faces of the guides, making sure that the teeth on the left side of the tool point towards the rear of the tool.

5.With one hand, hold the blade in place between the rollers and the guides and use the other hand to position the blade around the pulleys. Be sure that the blade lies freely within the guard channel before starting the tool motor.

6.Turn the tension lock handle 180° clockwise to lock the position. This will secure the blade on the pulleys.

BE SURE THAT THE BLADE IS PROPERLY SEATED ON THE PULLEYS BEFORE START- ING THE CUT.

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

dard Association and the
National Electrical Code.
Double Insulated tools may
be used in either of the
