ELECTRICAL SAFETY

WORK AREA SAFETY

• Grounded tools must be plugged into an outlet properly installed and grounded in accordance with all codes and ordinances. Never remove

the grounding prong or modify the plug in any way. Do not use any adaptor plugs. Check with a qualiﬁ ed electrician if you are in doubt as to whether the outlet is properly grounded. If the tool should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user.

• Double insulated tools are equipped with a polarized plug (one blade is wider than the other). This plug will ﬁ t in a polarized outlet only one way. If the plug does not ﬁ t fully in the outlet, reverse the plug. If it still does not ﬁ t, contact a qualiﬁ ed electrician to install a polarized outlet. Do not change the plug in any way. Double insulation

• Unplug tool when it is not in use, before changing accessories or performing recommended maintenance.

• Store idle tools. When not in use, store your tool in a dry, secured place. Keep out of reach of children.

• Never leave the tool running unattended. Turn power off. Do not leave the tool until it comes to a complete stop.

• Check for damaged parts. Inspect guards and other parts before use. Check for misalignment, binding of moving parts, improper mounting, broken parts and any other conditions that may affect 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. A guard or other damaged part should be properly repaired or replaced by a MILWAUKEE service facility . For all repairs, insist on only identical replacement parts.

• Use proper accessories. Consult this manual for recommended accessories. Using improper accessories may be hazardous. Be sure accessories are properly installed and maintained. Do not defeat a guard or other safety device when installing an accessory or attachment.

• Maintain tools carefully. Keep handles dry, clean and free from oil and grease. Keep cutting edges sharp and clean. Follow instructions for lubricating and changing accessories. Periodically inspect tool cords and extension cords for damage. Have damaged parts repaired or replaced by a MILWAUKEE service facility.

• Maintain labels & nameplates. These carry important information. If unreadable or missing, contact a MILWAUKEE service facility for a free replacement.

SERVICE

• Tool service must be performed only by quali-

ﬁ ed repair personnel. Service or maintenance performed by unqualiﬁ ed personnel may result in a risk of injury.

• When servicing a tool, use only identical replacement parts. follow instructions in the maintenance section of this manual. Use of

unauthorized parts or failure to follow maintenance instructions may create a risk of shock or injury.

SPECIFIC SAFETY RULES

WARNING T o reduce the risk of injury ,

avoid inhalation of dust generated by grinding and cutting operations. Exposure to dust may cause respiratory ailments. Use approved NIOSH or OSHA respirators, safety glasses or face shields, gloves and protective clothing. Provide adequate ventilation to eliminate dust, or to maintain dust level below the Threshold Limit Value for nuisance dust as classiﬁ ed by OSHA.

• 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 ﬁ lter out microscopic particles.

Wheel Instructions

• Use only the edge (not the sides) of the wheel for

cutting. Do not allow the wheel to twist or bind.

• Keep hands and body away from the rotating wheel. Do not wear loose clothing when using this tool.

• Store cut-off wheels with care. Do not drop them or subject them to excessive heat, cold or humidity.

• Make sure that all wheel ﬂ anges and other mount- ing hardware are in good condition and are always used properly. Defective or missing parts may cause damage to the wheel. Always use mounting ﬂ anges supplied with the tool.

• Cutting with a damaged wheel is very hazardous. After installing a new wheel, leave the tool unplugged and rotate the wheel by hand to see if it is uneven, warped, or cracked. If so, discard the wheel and replace it with a new one. Do not use a wheel that has been dropped; impact may result in breakage.

• Before starting a cut, step back from the tool and make a trial run to conﬁ rm that the wheel is in good condition. Trial run periods are:

When replacing a cut-off wheel — over 3 minutes. When starting routine work — over 1 minute.

• Never try to remove or clamp the workpiece to the tool while the cut-off wheel is rotating.

• Before installing a cut-off wheel, always inspect it for cracks. Visually check resinoid and rubberbonded wheels for cracks. Replace cracked wheel immediately.

• Always check maximum operating speed established for wheel against machine speed. Do not exceed the maximum operating speed that is marked on the wheel.

• Do not force a wheel onto the machine or alter the size of the arbor hole. Don’t use a wheel that ﬁ ts the arbor too loosely. If the wheel doesn’t ﬁ t the machine, get one that does.

• Do not attempt to install saw blades on this tool because it is not designed for this type of blade.

• Do not overtighten wheel nut.

Machine Instructions

• Start cutting only after the motor has reached full

speed.

• Release switch immediately if the cut-off wheel stops rotating or if the motor sounds like it is straining.

• Keep ﬂ ammable and fragile objects away from this tool. Do not allow cut-off sparks to contact the operator’s hands, face or feet.

• Place the tool securely on a ﬂ at, level surface.

• Always use the tool with the proper voltage speci-

ﬁ ed on the tool’s nameplate.

• Never touch a short cut-off piece until it cools.

• Never attempt to cut material larger than the rated

capacity listed in “Speciﬁ cations”.

• Never stand in line with the wheel while cutting. Always stand to the side.

• Always keep guards in place.

• Always start the cut gently. Do not bump or bang

a wheel to start a cut.

• Never make any freehand cuts. Always place the workpiece between the vise and fence when making cuts.

GROUNDING

WARNING Improperly connecting the

grounding wire can result in the risk of electric shock. Check with a qualiﬁ ed electri- cian 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: T ools 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 satisﬁ es 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

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 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.

Recommended Minimum Wire Gauge

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