Power Tool Safety Rules
! WARNING Read and understand all instructions. Failure to follow all instructions listed below, may result in electric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
Work Area
Keep your work area clean and well lit.
Cluttered benches and 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 which may ignite the dust or fumes.
Keep by-standers, children, and visitors away while operating a power tool.
Distractions can cause you to lose control.
Electrical Safety
Double Insulated tools are equipped with a polarized plug (one blade is wider than the other.) This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install a polarized outlet. Do not change the plug in any way. Double Insulation
eliminates the need for the three wire
grounded power cord and grounded power supply system. Before plugging in the tool, be certain the outlet voltage supplied is within the voltage marked on the nameplate. Do not use ìAC onlyî rated tools with a DC power supply.
Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of
electric shock if your body is grounded. If operating the power tool in damp locations is unavoidable, a Ground Fault Circuit Interrupter must be used to supply the power to your tool. Electrician’s rubber gloves and footwear will further enhance your personal safety.
Don't 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 to carry the tools or pull the plug from an outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged
cords immediately. Damaged cords increase the risk of electric shock.
When operating a power tool outside, use an outdoor extension cord marked "W-A" or "W." These cords are rated for outdoor use
and reduce the risk of electric shock. Refer to “Recommended sizes of Extension Cords” in the Accessory section of this manual.
Personal Safety
Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while
operating power tools may result in serious personal injury.
Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.
Keep handles dry, clean and free from oil and grease.
Avoid accidental starting. Be sure switch is ìOFFî before plugging in. Carrying tools with
your finger on the switch or plugging in tools that have the switch “ON” invites accidents.
Remove adjusting keys or wrenches before turning the tool ìONî. A wrench or a key that
is left attached to a rotating part of the tool may result in personal injury.
Do not overreach. Keep proper footing and balance at all times. Proper footing and
balance enables better control of the tool in unexpected situations.
Use safety equipment. Always wear eye protection. Dust mask, non-skid safety
shoes, hard hat, or hearing protection must be used for appropriate conditions.
Tool Use and Care
Use clamps or other practical way to secure and support the workpiece to a
-2-
BM 1609929C33 10/03 10/28/03 2:49 PM Page 3
stable platform. Holding the work by hand or against your body is unstable and may lead to loss of control.
Do not force tool. Use the correct tool for your application. The correct tool will do the
job better and safer at the rate for which it is designed.
Do not use tool if switch does not turn it ìONî or ìOFFî. Any tool that cannot be
controlled with the switch is dangerous and must be repaired.
Disconnect the plug from the power source before making any adjustments, changing accessories, or storing the tool. Such
preventive safety measures reduce the risk of starting the tool accidentally.
Store idle tools out of reach of children and other untrained persons. Tools are
dangerous in the hands of untrained users.
Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools, with sharp cutting edges are less likely to bind and are easier to control. Any alteration or modification is a misuse and may result in a dangerous condition.
Check for misalignment or binding of moving parts, breakage of parts, and any
other condition that may affect the tools operation. If damaged, have the tool serviced before using. Many accidents are
caused by poorly maintained tools. Develop a periodic maintenance schedule for your tool.
Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for
one tool, may become hazardous when used on another tool.
Service
Tool service must be performed only by qualified repair personnel. Service or
maintenance performed by unqualified personnel could result in a risk of injury. For example: internal wires may be misplaced or pinched, safety guard return springs may be improperly mounted.
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 electric shock or injury. Certain cleaning agents such as gasoline, carbon tetrachloride, ammonia, etc. may damage plastic parts.
Angle Grinder Safety Rules
Always use proper guard with grinding wheel. A guard protects operator from
broken wheel fragments. When using grinding wheel attachments, the guard must always be attached to the tool and positioned for maximum safety, so the least amount of wheel is exposed from the side the tool is being operated.
Accessories must be rated for at least the speed recommended on the tool warning
label. Wheels and other accessories running over rated speed can fly apart and cause injury. Grinding wheels or any other accessory must have a maximum safe operating speed greater than the “no load RPM” marked on the tool’s nameplate.
Hold tool by insulated gripping surfaces when performing an operation where the cutting tools 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.
Always use auxiliary handle for maximum control over torque reaction or kick-back.
Operation of the grinder without the side handle could cause loss of control of the grinder, resulting in possible serious personal injury.
Before using a grinder or installing a new wheel, inspect the grinding wheel for chips and cracks. Remove bad wheels immediately. Run the tool at no load for one minute, holding the tool in the direction away from people. Wheels with
flaws will normally break apart during this time.
Carefully handle both the tool and individual grinding wheels to avoid chipping or cracking. Install a new wheel if tool is dropped while grinding. Do not
-3-
BM 1609929C33 10/03 10/28/03 2:49 PM Page 4
use a wheel that may be damaged.
Fragments from a wheel that bursts during operation will fly away at great velocity possibly striking you or bystanders.
Do not use grinding wheel that is larger than the maximum recommended size for your tool, or worn down damaged wheels from larger grinders. Wheels intended for
large angle sander/grinders are not suitable for the high speed of a small angle sander/grinder, these wheels may easily burst and the fragments strike you or bystanders.
Do not use depressed hub grinding wheels for cut-off operations. Depressed
hub wheels or type 27 wheels are not intended for side loading and may shatter under overload.
Do not use this tool with ìWoodcarvingî blade. Such blades create frequent kick-
back and loss of control.
Wear proper apparel while using a sander/grinder. Face shield or at least
safety goggles, dust mask, leather gloves and shop apron capable of stopping small wheel or workpiece fragments.
Position the cord clear of the spinning grinding wheel or any other sanding accessory. Do not wrap the cord around your arm or wrist. If you lose control and
have the cord wrapped around your arm or wrist it may entrap you and cause injury.
Avoid bouncing and snagging the wheel, especially when working corners, sharp edges etc. This can cause loss of control
and kick-back.
Regularily clean the toolís air vents by compressed air. Excessive accumulation of
powdered metal inside the motor housing may cause electrical failures.
-4-
Do not grind or sand near flammable materials. Sparks from the wheel could
ignite these materials.
This tool can be converted to a sander. When grinding is resumed the proper guard and wheel flanges MUST be reinstalled before proceeding with grinding. The guard must always be attached to the tool and positioned for maximum safety, so the least amount of wheel is exposed from the side the tool is being operated. The grinding wheel guard
cannot be used for most sanding operations or for wire brushing.
When sanding, do not use oversized sanding disc. Larger sanding disc will
extend beyond the sanding pad causing snagging, tearing of the disc or kick-back. Extra paper extending beyond the sanding pad can also cause serious lacerations.
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 paints,
•Crystalline silica from bricks and cement and other masonry products, and
•Arsenic and chromium from chemicallytreated 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.

Operating Instructions
SLIDE ON-OFF SWITCH WITH LOCK
The tool is switched “ON” by the switch button located at the side of the motor housing. The switch can be locked in the “ON” position, a convenience for long grinding operations.
TO TURN THE TOOL “ON” without locking it, slide the switch button forward by applying pressure ONLY at the REAR portion of the button. When pressure is released the switch button will snap to “OFF” position.
TO LOCK THE SWITCH “ON”, slide the switch button forward and press “IN” the FRONT portion.
TO UNLOCK THE SWITCH, simply press and release the REAR portion of the button. Switch is spring loaded and will snap back automatically.
! WARNING Hold the tool with both hands while starting the
tool, since torque from the motor can cause the tool to twist.
Start the tool before applying to work and let the tool come to full speed before contacting
the workpiece. Lift the tool from the work before releasing the switch. DO NOT turn the switch “ON” and “OFF” while the tool is under load; this will greatly decrease the switch life.
ELECTRONIC FEEDBACK CIRCUITRY (EFC)
(1703EVS ONLY)
The internal electronic feedback system provides a "soft start", which will reduce the stresses that occur from a high torque start. The system also helps to keep the no load speed virtually constant between no-load and load conditions.
OVERLOAD PROTECTION
(1703EVS ONLY)
Your tool is equipped with overload protection to protect the motor. If the tool stops during operation TURN OFF SWITCH IMMEDIATELY and allow the motor to cool for about 30 seconds by running at no-load. If the overload protection stops the tool repeatedly, excessive force is causing the tool to overload. Don't press so hard and let the tool do the work.
VARIABLE SPEED WITH DIAL SETTING
(1703EVS ONLY)
Your tool is also equipped with a variable speed dial. The grinder’s RPM can be preset from zero to maximum nameplate rated RPM by rotating the dial on the motor housing. If tool is running at a set speed for extended periods of time, it may be necessary to run the tool at noload full speed to cool the motor.

Grinding Operations
SELECTING GRINDING WHEELS
! WARNING Before using a grinding wheel, be certain that its
maximum safe operating speed is not exceeded by the nameplate speed of the grinder. Do not exceed the recommended wheel diameter.
DISC GRINDING WHEELS
Grinding wheels should be carefully selected in order to use the grinder most efficiently. Wheels vary in type of abrasive, bond, hardness, grit size and structure. The correct type of wheel to use is determined by the job. Use disc grinding wheels for fast grinding of structural steel, heavy weld beads, steel casting, stainless steel and other ferrous metals.
GRINDING TIPS
Efficient grinding is achieved by controlling the pressure and keeping the angle between wheel and workpiece at 10° to 15°. If the wheel is flat, the tool is difficult to control. If the angle is too steep, the pressure is concentrated on a small area causing burning to the work surface.
! WARNING Excessive or sudden pressure on the wheel will slow
grinding action and put dangerous stresses on the wheel.
When grinding with a new wheel be certain to grind while pulling tool backwards until wheel becomes rounded on its edge. New wheels have sharp corners which tend to “bite” or cut into workpiece when pushing forward.
Sanding Operations
SELECTING SANDING DISC
Sanding discs are made of extremely hard and sharp aluminum oxide grits, phenolresin bonded to a sturdy fiber backing for fast heavy-duty service and long life. The discs vary as to size and spacing of the abrasive grits. OPEN COAT (type H) — used for soft materials and on paint or varnish. CLOSED COAT (type K) —used for metal, hardwood, stone, marble and other materials.
Sanding discs range in grit from 16 (very coarse) to 180 (very fine). To obtain best results, select sanding discs carefully. Many
jobs require the use of several grit sizes and at times both “open coat and closed coat” discs are required to get the job done faster. See chart for application examples.
Operation: Refinishing painted wood or metal surfaces.

SANDING TIPS
For best results, tilt the Disc Sander at a 10° to 15° angle while sanding so that only about 1" of the surface around the edge of the disc contacts the work.
! WARNING If the disc (accessory) is held flat or the back edge of the
disc comes in contact with the work, a violent thrust to the side may result.
If sander is tilted too much, sanding action will be too great and a rough cut surface or gouging and snagging will result.
Guide the Disc Sander with crosswise
strokes. Be careful not to hold the sander in one spot too long. Do not use a circular motion, as this makes swirl marks. Test before use on scrap stock.
Do not force or apply pressure when sanding. Use only the weight of the tool for pressure. Excess pressure actually slows the tool down. If faster stock removal is desired, change to a coarser grit disc.
Remove gummy paint from metal with an “open coat” disc. Sand until sparks start to appear, then stop and change to a “closed coat” disc to remove any remaining paint.
-10-
BM 1609929C33 10/03 10/28/03 2:49 PM Page 11
SANDING WOOD
When sanding wood the direction of the disc motion at the contact point should parallel the grain as much as possible. The rapid cut of discs and the swirl type scratch pattern they occasionally create generally prohibit their use for producing the final finish.
Scratches and circular marks are usually the result of using too coarse a grit. When changing to a finer grit, move across the sanding lines that were made by a previous coarser disc.
SANDING METAL
When sanding automobiles or appliances, wipe the metal clean with a non-flammable solvent or commercial cleaner to remove all wax and grease. By doing this first, the sanding discs will sand better and last longer.
For heavy duty work, use a coarse grit disc first. Follow-up with a medium grit to remove scratches. To produce smooth finish, use fine grit disc.
Wire Brush Operations
Wire brushes are intended to “clean” structural steel, castings, sheet metal, stone and concrete. They are used to remove rust, scale and paint.
! WARNING Avoid bouncing and snagging the wire brush, especially
when working corners, sharp edges etc. This can cause loss of control and kick-back.
BRUSHING PRESSURE
1.Remember, the tips of a wire brush do the work. Operate the brush with the lightest pressure so only the tips of the wire come in contact with the work.
2.If heavier pressures are used, the wires will be overstressed, resulting in a wiping
action; and if this is continued, the life of the brush will be shortened due to wire fatigue.
3. Apply the brush to the work in such a way that as much of the brush face as possible is in full contact with the work. Applying the side or edge of the brush to the work will result in wire breakage and shortened brush life.
