TECHNICAL DATA

GENERAL SAFETY WARNINGS

WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire, and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

WORK AREA SAFETY

• Keep the work area clean and well-lit. Cluttered or dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks that may ignite dust or fumes.
• Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

• 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. Unmodified plugs and matching outlets will reduce the risk of electric shock.

• 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.

• Do not expose this product to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

• 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.

• When operating a power tool outdoors, use an extension cord suitable for outdoor use. The use of a cord suitable for outdoor use reduces the risk of electric shock.

• If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. The use of an RCD reduces the risk of electric shock.

PERSONAL SAFETY

• 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 influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury.

• Use personal protective equipment. Always wear eye protection. Protective equipment such as dust masks, nonskid safety shoes, hard hats, or hearing protection used for appropriate conditions will reduce personal injuries.

• Prevent unintentional starting. Ensure the switch is in the off-position before connecting to a power source and/ or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invite accidents.

• 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.

• Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

• Dress properly. Do not wear loose clothing or jewelry.
  Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.

• If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. The use of dust collection can reduce dust-related hazards.

POWER TOOL USE AND CARE

• Do not force the product. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate at which it was designed.
• Do not use the power tool if the switch does not turn on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
• 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 power tool accidentally.
• Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
• 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.
• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
• Use the power tool, accessories and tool bits, etc. in accordance with these instructions, 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.

SERVICE

• Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

SAFETY INSTRUCTIONS

Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
Wear ear protectors. Exposure to noise can cause hearing loss.
Always wear goggles when using the machine. It is recommended to wear gloves, sturdy nonslipping shoes, and an apron.
Sawdust and splinters must not be removed while the machine is running.
The dust produced when using this tool may be harmful to health.
Do not inhale the dust. Wear a suitable dust protection mask.
Do not use cracked or distorted saw blades.

SPECIFIED CONDITIONS OF USE

The band saw cuts lengthways and miter accurately in different types of metals such as metal profi Les (UniStrut), pipes, metal studs, channels, aluminum profi les, and metal sheets.
Do not use this product in any other way as stated for normal use.

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

• 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.

**Recommended minimum wire gauge for extension cords***

*Based on limiting the line voltage drop to fi ve volts at 150% of the rated amperes.

WARNING
To reduce the risk of injury, always unplug tools before changing or removing accessories. Only use accessories specifi cally recommended for this tool. Others may be hazardous.

BLADES AND BLADE SELECTION
The blade dimensions required for the band saws are 0.02” thickness, 1/2” width, and 44-7/8” in length. The special 0.02” thickness reduces flexure fatigue and provides maximum tooth life. To 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 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.

WARNING!
Do not touch the blade immediately after use. The 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.
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.

SPEED DIAL
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 and “1” for minimum speed.

STARTING AND STOPPING

1. To start the tool, grasp both handles firmly 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 stop the tool, release the trigger. Allow the tool to come to a complete stop before removing the blade from a partial cut or laying down the tool.

TYPICAL APPLICATION

1. Keep the blade off of 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.
3. Place the material guide 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 firmly so it will not fall against the workpiece.
