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

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.

WARNING To reduce the risk of injury, always unplug tool before changing or re- moving accessories. Only use accessories specifically recommended for this tool. 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").

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.

To line-up a cut or light-up the workpiece, use the LED On/Off Switch.

Adjusting the 3-Position Material Guide

1.Unplug the tool.

2.Press in the guide adjustment button and slide the material guide to the desired position detent.

OPERATION

WARNING To reduce the risk of injury, always unplug tool before attaching or remov- ing accessories or making adjustments. Use only specifically recommended accessories.

an electrically “live” terminal.

 

Your tool must be plugged into

 

an appropriate outlet, properly

 

installed and grounded in accord-

 

ance with all codes and ordinances.

 

The plug and outlet should look like

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 Laboratories, Inc.,

 

the Canadian Standard Asso-

 

ciation and the National Elec-

 

trical Code. Double Insulated

 

tools may be used in either of

 

the 120 volt outlets shown in

WARNING To reduce the risk of injury, wear safety goggles or glasses with side shields. Keep hands away from the blade and all moving parts.

Two Speed Switch (Cat. No. 6238-20)

MILWAUKEE Two-Speed Band Saws have a speed change switch located on top of the handle. To change speeds, stop the motor and slide the speed change switch to "HI" or "LO" as indicated on the tool. For cutting problem materials, use "LO" speed. Never change from one speed to the other while the motor is running.

Speed Dial (Cat. No. 6232-20)

MILWAUKEE Variable Speed Band Saws have a speed dial located on the side of the handle to set the maximum speed. Rotate the speed dial to “4” for maximum speed, “1” for minimum speed.

WARNING Do not touch blade imme- diately after use. Blade will be hot.

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.

Starting and Stopping

1.To start the tool, grasp both handles firmly and pull the trigger.
