GENERAL SAFETY RULES — FOR ALL POWER TOOLS
WARNING
Failure to follow all instructions listed below may result in electric shock, fi re and/or serious injury. The term "power tool" in all of the warn- ings listed below refers to your mains-operated (corded) power tool or battery-opearted (cordless) power tool.
SAVE THESE INSTRUCTIONS
READ ALL INSTRUCTIONS
WORK AREA SAFETY
1. Keep work area clean and well lit. Cluttered or dark areas invite ac­cidents.
2. Do not operate power tools in explosive atmospheres, such as in the presence of ammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.
3. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
4. Power tool plugs must match the outlet. Never modify the plug in
any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodi ed plugs and matching outlets will reduce risk
of electric shock.
5. Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
6. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
7. Do not abuse the cord. Never use the cord for carrying, pulling, or
unplugging the power tool. Keep cord away from heat, oil, sharp edges, or moving parts. Damaged or entangled cords increase the
risk of electric shock.
8. When operating a power tool outdoors, use an extension cord suit- able for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
PERSONAL SAFETY
16. Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at
the rate for which it was designed.
17. Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
18. Disconnect the plug from the power source and/or the battery pack
from the power tool before making any adjustments, changing ac­cessories, or storing power tools. Such preventive safety measures
reduce the risk of starting the tool accidentally.
19. Store idle power tools out of the reach of children and do not al-
low persons unfamiliar with the power tools or these instructions to operate power tools. Power tools are dangerous in the hands of
untrained users.
20. Maintain power tools. Check for misalignment or binding of moving
parts, breakage of parts and any other condition that may affect the power tool's operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power
tools.
21. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
22. Use the power tool, accessories and tool bits etc., in accordance
with these instructions and in the manner intended for the particu­lar type of power tool, taking into account the working conditions and the work to be performed. Use of the power tool for operations
different from those intended could result in a hazardous situation.
POWER TOOL USE AND CARE
SERVICE
9. Stay alert, watch what you are doing and use common sense when
operating a power tool. Do not use a power tool while you are tired or under the infl uence of drugs, alcohol or medication. A moment
of inattention while operating power tools may result in serious personal injury.
10. Use safety equipment. Always wear eye protection. Safety equip- ment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal inju­ries.
11. Avoid accidental starting. Ensure the switch is in the off-position before plugging in. Carrying tools with your fi nger on the switch or plugging in power tools that have the switch on invites accidents.
12. Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
13. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
14. Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery, or long hair can be caught in moving parts.
15. If devices are provided for the connection of dust extraction and
collection facilities, ensure these are connected and properly used.
Use of these devices can reduce dust-related hazards.

23. Have your power tool serviced by a qualifi ed repair person using only identical replacement parts. This will ensure that the safety of
the power tool is maintained.
SPECIFIC SAFETY RULES
1. Hold power tools 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.
2. Maintain labels and nameplates. These carry important information. If unreadable or missing, contact a MILWAUKEE service facility for a free re- placement.
3. 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 lead-based paint
crystalline silica from bricks and cement and other masonry products, and
arsenic and chromium from chemically-treated lumber.
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 specifi cally designed to fi lter out microscopic particles.

GROUNDING EXTENSION CORDS
WARNING
Improperly connecting the grounding wire can result in the risk of electric shock. Check with a qualifi ed 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 fi t the outlet, have a proper outlet installed by a qualifi ed 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.
Y our tool must be plugged into an appropriate outlet, properly installed and grounded in accordance with all codes and ordinances. 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 insulation system which satisfies OSHA requirements and complies with the applicable standards of Underwriters Laboratories, Inc., the Canadian Standard Association and the National Electrical Code. Double Insulated tools may be used in either of the 120 volt outlets shown in Figures B and C.
Fig. A
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 suffi x “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 qualifi ed person before using it.
Protect your extension cords from sharp objects, excessive heat and damp or wet areas.

TOOL ASSEMBLY
WARNING
To reduce the risk of injury, always unplug tool before attaching or removing accessories or making adjustments. Use only specifically recommended accessories. Others may be hazardous.
Blades and Blade Selection (Fig. 1)
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 fl exure fa- tigue and provides maximum tooth life. T o maximize cutting life, use a blade with the correct pitch (teeth per inch) for the specifi c 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 specifi c size, shape and type of material to be cut. Generally, soft materials require coarse pitch blades and hard materials require fi ne pitch blades. Use coarse pitch blades for thick work and fi ne pitch blades for thin work. It is important to keep at least three teeth in the cut (see "Typical Application").
Fig. 1
6 Teeth per Inch
For tough stock 1/2" to 3-3/8" in diameter or width (available in carbon steel only).
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 fi rst 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 STARTING THE CUT.

OPERATION
WARNING
To reduce the risk of injury, wear safety goggles or glasses with side shields. Unplug the tool before changing accessories or making adjustments.
Two Speed Switch (Cat. Nos. 6225 & 6236)
MILWAUKEE Two-Speed Band Saws are equipped with a speed change switch located below the trigger on 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.
Starting, Stopping, and Controlling Speed (Cat. No. 6230)
1. To start the tool, grasp the handle fi rmly and pull the trigger.
2. To vary the speed, increase or decrease pressure on the trigger. The further the trigger is pulled, the greater the speed.
3. To select a maximum preset speed at any point within the speed range, rotate the red knurled knob located on the trigger to the desired posi­tion.
4. To stop the tool, release the trigger. Allow the tool to come to a com- plete stop before removing the blade from a partial cut or laying the tool down.
Typical Application (Figs. 2 & 3)
1. Keep the blade off the workpiece until the motor has reached the se­lected speed.
2. Start cutting on a surface where the greatest number of teeth will be in contact with the workpiece at one time (Fig 2).
Fig. 2
Correct Incorrect
3. Place the work steady rest against the workpiece and lower the moving saw blade into the cut.
4. Do not bear down while cutting. The weight of the tool will supply ad­equate pressure for the fastest cutting.
5. When completing a cut, hold the tool fi rmly so it will not fall against the workpiece (Fig. 3).
