WARNING READ ALL SAFETY WARNINGS AND 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 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 1 ammable liquids, gases or dust. Power tools create sparks which may ignite the 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 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 power tools 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. 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. 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 mask, non-skid safety shoes, hard hat, 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 power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your anger on the switch or energising power tools that have the switch on invites 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 jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery 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. Use of these devices can reduce dust-related hazards.
POWER TOOL USE AND CARE
- 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.
- 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.
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.

SPECIFIC SAFETY RULES
Safety Warnings Common for Grinding, Sanding, Wire Brushing or Abrasive Cutting-Off Operations:
- This power tool is intended to function as a grinder, sander, wire brush or cut-off tool. Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, are and/or serious injury.
- Operations such as polishing are not recommended to be performed with this power tool. Operations for which the power tool was not designed may create a hazard and cause personal injury.
- Do not use accessories which are not specifically designed and recommended by the tool manufacturer. Just because the accessory can be attached to your power tool, it does not assure safe operation.
- The rated speed of the accessory must be at least equal to the maximum speed marked on the power tool. Accessories running faster than their rated speed can break and y apart.
- The outside diameter and the thickness of your accessory must be within the capacity rating of your power tool. Incorrectly sized accessories cannot be adequately guarded or controlled.
- The arbour size of wheels, flanges, backing pads or any other accessory must properly sit the spindle of the power tool. Accessories with arbour holes that do not match the mounting hardware of the power tool will run out of balance, vibrate excessively and may cause loss of control.
- Do not use a damaged accessory. Before each use inspect the accessory such as abrasive wheels for chips and cracks, backing pad for cracks, tear or excess wear, wire brush for loose or cracked wires. If power tool or accessory is dropped, inspect for damage or install an undamaged accessory. After Inspecting and installing an accessory, position yourself and bystanders away from the plane of the rotating accessory and run the power tool at maximum no-load speed for one minute. Damaged accessories will normally break apart during this test time.
- Wear personal protective equipment. Depending on application, use face shield, safety goggles or safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and work shop apron capable of stopping small abrasive or workpiece fragments. The eye protection must be capable of stopping a lying debris generated by various operations. The dust mask or respirator must be capable of a litrating particles generated by your operation.
Prolonged exposure to high intensity noise may cause hearing loss.
- Keep bystanders a safe distance away from work area. Anyone entering the work area must wear personal protective equipment. Fragments of workpiece or of a broken accessory may fly away and cause injury beyond immediate area of operation.
- Hold power tool by Insulated gripping surfaces only, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a live wire may make exposed metal parts of the power tool live and shock the operator.
- Position the cord clear of the spinning accessory. If you lose control, the cord may be cut or snagged and your hand or arm may be pulled into the spinning accessory.
- Never lay the power tool down until the accessory has come to a complete stop. The spinning accessory may grab the surface and pull the power tool out of your control.
- Do not run the power tool while carrying it at your side. Accidental contact with the spinning accessory could snag your clothing, pulling the accessory into your body.
- Regularly clean the power tool's air vents. The motor's fan will draw the dust inside the housing and excessive accumulation of powdered metal may cause electrical hazards.
- Do not operate the power tool near flammable materials. Sparks could ignite these materials.
- Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock.
Kickback and Related Warnings Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad, brush or any other accessory. Pinching or snagging causes rapid stalling of the rotating accessory which in turn causes the uncontrolled power tool to be forced in the direction opposite of the accessory's rotation at the point of the binding.
For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel that is entering into the pinch point can dig into the surface of the material causing the wheel to climb out or kick out. The wheel may either jump toward or away from the operator, depending on direction of the wheel's movement at the point of pinching. Abrasive wheels may also break under these conditions.
Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below.
Maintain a firm grip on the power tool and position your body and arm to allow you to resist kickback forces. Always use auxiliary handle, if provided, for maximum control over kickback or torque reaction during start-up. The operator can control torque reactions or kickback forces, if proper precautions are taken.
- Never place your hand near the rotating accessory. Accessory may kick back over your hand.
- Do not position your body in the area where power tool will move if kickback occurs. Kickback will propel the tool in direction opposite to the wheel's movement at the point of snagging.
- Use special care when working corners, sharp edges etc. Avoid bouncing and snagging the accessory. Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and cause loss of control or kickback.
- Do not attach a saw chain woodcarving blade or toothed saw blade. Such blades create frequent kickback and loss of control.
Safety Warnings Specific for Grinding and Abrasive Cutting-Off Operations: - Use only wheel types that are recommended for your power tool and the special guard designed for the selected wheel. Wheels for which the power tool was not designed can not be adequately guarded and are unsafe.
- The guard must be securely attached to the power tool and positioned for maximum safety, so the least amount of wheel is exposed towards the operator. The guard helps to protect operator from broken wheel fragments and accidental contact with wheel.
- Wheels must be used only for recommended applications. For example: do not grind with the side of cut-off wheel. Abrasive cut-off wheels are intended for peripheral grinding, side forces applied to these wheels may cause them to shatter.
- Always use undamaged wheel ranges that are of correct size and shape for your selected wheel. Proper wheel ranges support the wheel thus reducing the possibility of wheel breakage. Flanges for cut-off wheels may be different from grinding wheel ranges.
- Do not use worn down wheels from larger power tools. Wheel intended for larger power tool is not suitable for the higher speed of a smaller tool and may burst.
Additional Safety Warnings Speci c for Abrasive Cutting-Off Operations: - Do not jam the cut-off wheel or apply excessive pressure. Do not attempt to make an excessive depth of cut. Overstressing the wheel increases the loading and susceptibility to twisting or binding of the wheel in the cut and the possibility of kickback or wheel breakage.
- Do not position your body in line with and behind the rotating wheel. When the wheel, at the point of operation, is moving away from your body, the possible kickback may propel the spinning wheel and the power tool directly at you.
- When wheel is binding or when Interrupting a cut for any reason, switch off the power tool and hold the power tool motionless until the wheel comes to a complete stop. Never attempt to remove the cut-off wheel from the cut while the wheel is in motion otherwise
kickback may occur. Investigate and take corrective action to eliminate the cause of wheel binding.
Do not restart the cutting operation in the workpiece. Let the wheel reach full speed and carefully reenter the cut. The wheel may bind, walk up or kickback if the power tool is restarted in the workpiece.
Support panels or any oversized workpiece to minimize the risk of wheel pinching and kick-back. Large workpieces tend to sag under their own weight. Supports must be placed under the workpiece near the line of cut and near the edge of the workpiece on both sides of the wheel.
Use extra caution when making a "pocketcut" into existing walls or other blind areas. The protruding wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback.
Safety Warnings Speci a c for Sanding Operations:
Do not use excessively oversized sanding disc paper. Follow manufacturers recommendations, when selecting sanding paper. Larger sanding paper extending beyond the sanding pad presents a laceration hazard and may cause snagging, tearing of the disc or kickback.
Safety Warnings Speci c for Wire Brushing Operations:
Be aware that wire bristles are thrown by the brush even during ordinary operation. Do not over stress the wires by applying excessive load to the brush. The wire bristles can easily penetrate light clothing and/or skin.
If the use of a guard is recommended for wire brushing, do not allow any interference of the wire wheel or brush with the guard. Wire wheel or brush may expand in diameter due to workload and centrifugal forces.
Additional Safety Warnings
Maintain labels and nameplates. These carry important information. If unreadable or missing, contact a MILWAUKEE service facility for a free replacement.
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 specially designed to filter out microscopic particles.

GROUNDING
WARNING Improperly connecting the grounding wire can result in the risk of electric 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 sit 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 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. B Fig. C
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
- 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.
Recommended Minimum Wire Gauge for Extension Cords*

USING GRINDING WHEELS
WARNING To reduce the risk of injury, operator should be instructed in the use, and protection of grinding wheels.
Grinding Wheel Selection
Use grinding wheels, and accessories that are: - correct size as written on tool's nameplate.
- rated at or above the RPM listed on the tool's nameplate.
- correct accessory, wheel type and grit for the job. Grinding is the cutting action of thousands of abrasive grains on the face of a grinding wheel. When grinding metals such as steel and iron, choose an aluminum oxide grinding wheel. Select a silicon carbide grinding wheel for stone and concrete. Use cotton reinforced wheels for non-ferrous metals. Type 27 Reinforced 1/8" thick or less Cut-Off Wheels are suited for small cut-off and shallow notching operations only. Always handle wheels carefully to avoid damage. Before installing any wheel, always inspect it for cracks. If wheel is cracked, discard it to prevent others from using it.
Care of Grinding & Cut-Off Wheels
Grinding/cut-off wheels should be protected from:
- wetness and extreme humidity
- any type of solvent
- extreme changes in temperature
- dropping and bumping
Grinding and cut-off wheels should be stored:
- in an organized way so wheels can be removed without disturbing or damaging other wheels
• with their safety information
Grinding and cut-off wheels should NOT be dropped, rolled or bumped.
Discard wheels that have been dropped, rolled, bumped, subjected to extreme changes in temperature, or come into contact with solvents or wetness.
Grinding
When grinding, hold tool at a 5° to 15° angle, using constant pressure for a uniform finish. Too great an angle causes concentrated pressure on small areas which may gouge or burn work surface.
USING CUT-OFF WHEELS
WARNING A Type "1" guard must be called when using a cut-off wheel to provide maximum protection for the operator if the set should break.
Type "1" Cut-Off Wheels are suited for small cut-off and shallow notching operations only.
When using a cut-off wheel, hold the tool as shown, using only the edge of the wheel.
Fig. 6
WARNING Using the face of a Cut-Offel (as in grinding) will cause the Wheelack and break, resulting in serious per-1 injury.
USING WIRE BRUSHES
WARNING Everyone in the area must wear protective clothing and safety styles or face shields. Fatigued wires and blue will play off the brush with considerable use, causing potential for serious injury.
Wire brushes are useful for removing rust, scale, burrs, weld slag, etc.
Always install wire cup brushes according to the accessory manufacturer's instructions.

WARNING Because the wires on wire wheel brushes are directed towards theator, a guard must be used to protect theator when fatigued wires break.
When using a wire wheel brush, install guard according to "Installing/Removing Accessories".
Test wheel for balance and loose or damaged wires by letting it spin for one minute before applying it to the workpiece. During this time, no one should stand in front of or in line with it.
Control pressure and surface contact between wheel and workpiece. Too much pressure causes over-bending of wires and heat build-up causing premature wire breaking, rapid dulling and reduced brush life. Instead of more pressure, try a wire wheel with more aggressive cutting action (increased wire size, decreased wire length or different brush type (knot type vs.crimped wire type).
WARNING Never exceed Maximum Safe Operating Speed of brush. Do not use a damaged brush or one that is functioning Improperly (throwing wires, out-of-balance, etc.). These conditions increase the possibility of further brush failure and possible Injury. Discard and replace damaged brushes immediately.
USING SANDING DISCS
Sanding Disc Selection
Use sanding discs and accessories that are:
- correct size as written on tool's nameplate.
- rated at or above the RPM listed on the tool's nameplate.
- correct accessory, wheel type and grit for the job. Refer to the table below to select the correct type of sanding disc for your job. Generally, use 24 or 36 grit for heavy stock removal; 50, 60, or 80 grit for medium stock removal and 120 grit for nishing. Always begin with a coarse grit, using successively inner grits to obtain the desired finish. See your MILWAUKEE Electric Tool Catalog for a complete list of sanding discs.
Aluminum Oxide
For fast cutting, general purpose discs for most metal jobs. Best for cold-rolled steel, stainless steel or metals requiring tough, fast cutting, long lasting abrasives.
Aluminum Zirconia Bi-Cut
Unique grit pattern is arranged in clusters for faster stock removal and cleaning. Ideal for removing paint from cars, boats, etc. without clogging.
Ceramic
Lasts up to 3 times longer than Aluminum Oxide Discs. For general metal working. Ideal for tough jobs.
Installing Backing Pad and Sanding Discs
-
Unplug the tool.
-
Wipe the accessories, disc nut and spindle to remove dust and debris. Inspect the parts for damage. Replace if needed.
-
Slip backing pad onto spindle with flat side away from gear case.
-
Place sanding disc on backing pad and secure assembly to spindle with disc nut.
-
To tighten, press the spindle lock button while turning disc nut clockwise with the spanner wrench provided.
-
To remove backing pad and sanding disc, unplug the tool and reverse the procedure.
Sanding
Hold tool at 5^ to 15^ angle to ensure proper sanding pressure and control. Too great an angle will result in too much pressure and could cause excessive wear to the disc and workpiece. Too small an angle will reduce control.
Use long, sweeping, side to side strokes, advancing forward to produce the desired finish.
Cross Sanding
When finishing a surface that has been prepared by a coarse disc or wheel, sand at right angles to the strokes made by the coarser disc. Finishing marks left from previous sanding are easily seen and removed for a uniform finish. Failure to cross sand when changing from a coarse disc to a finishing disc may result in deep scratches and circular marks.
Removing Welds or Hammer Marks
When removing welds or hammer marks, limit coarse sanding to the immediate area. Use successively inner grits to smooth surface.
Finishing Metal
Constantly move across the surface. Work faster on curved surfaces where contact areas are smaller and pressure is greater. Flat areas may appear at the end of the stroke when pressure is too heavy. Ease up on pressure at end of each stroke and when reversing strokes.
Troubleshooting
Deep scratches and circular marks can result from:
• Using too coarse a grit
• Using a partially glazed disc
- Dirt or loose metal on the workpiece
- Failure to sand across the grain when changing from coarse to finishing discs
- Failure to use closed coated discs to reduce the problem of grains working loose and scratching the workpiece
Bluish discoloration of metal surface indicates:
• Excessive heat caused by circular motion in a small area
• Excessive pressure
• Use of worn out or glazed discs
MAINTENANCE
WARNING To reduce the risk of injury, always unplug your tool before performing any maintenance. Never disassemble the tool or try to do any rewiring on the tool's electrical system. Contact a MILWAUKEE service facility for ALL repairs.
Maintaining Tools
Keep your tool in good repair by adopting a regular maintenance program. Before use, examine the general condition of your tool. Inspect guards, switches, tool cord set and extension cord for damage. Check for loose screws, misalignment, binding of moving parts, improper mounting, broken parts and any other condition that may affect its safe operation. If abnormal noise or vibration occurs, turn the tool off immediately and have the problem corrected before further use. Do not use a damaged tool. Tag damaged tools "DO NOT USE" until repaired (see "Repairs").
Under normal conditions, relubrication is not necessary until the motor brushes need to be replaced. After six months to one year, depending on use, return your tool to the nearest MILWAUKEE service facility for the following:
- Lubrication
• Brush inspection and replacement
- Mechanical inspection and cleaning (gears, spindles, bearings, housing, etc.)
• Electrical inspection (switch, cord, armature, etc.)
- Testing to assure proper mechanical and electrical operation
WARNING To reduce the risk of Injury, electric shock and damage to the tool, never immerse your tool in liquid or allow a liquid to flow inside the tool.
Cleaning
Clean dust and debris from vents. Keep the tool handles clean, dry and free of oil or grease. Use only mild soap and a damp cloth to clean your tool since certain cleaning agents and solvents are harmful to plastics and other insulated parts. Some of these include: gasoline, turpentine, lacquer thinner, paint thinner, chlorinated cleaning solvents, ammonia and household detergents containing ammonia. Never use ammable or combustible solvents around tools.
Repairs
If your tool is damaged, return the entire tool to the nearest service center.
ACCESSORIES
WARNING To reduce the risk of injury, always unplug the tool before attaching or removing accessories. Use only specifically recommended accessories. Others may be hazardous.
For a complete listing of accessories refer to your MILWAUKEE Electric Tool catalog or go on-line to www.milwaukeetool.com. To obtain a catalog, contact your local distributor or a service center.
