General Safety Rules
SAVE THESE INSTRUCTIONS
WARNING! Read all instructions Failure to follow all
instructions listed below may result in electric shock, fire and/or serious injury. The term “power tool” in all of the warnings listed below refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
1) Work area
a) Keep work area clean and well lit. Cluttered and
dark areas invite accidents.
b) 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.
c) Keep children and bystanders away while operating a power tool. Distractions can cause you
to lose control.
2) Electrical safety
a) 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
b) 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.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase
the risk of electri
c shock.
d) 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.
e) 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.
3) Personal safety
a) 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.
b) Use safety equipment. Always wear eye protection.Safety equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
c) Avoid accidental starting. Ensure the switch is in the off-position before plugging in. Carrying
power tools with your finger on the switch or
plugging in power tools that have the switch on
invites accidents.
d) 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.
e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
f ) 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.
g) 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.
4) Power tool use and care
a) 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.
b) 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.
c) Disconnect the plug from the power source before making any adjustments, changing accessories, or storing power tools. Such
preventive safety measures reduce the risk of starting the power tool accidentally.
d) 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.
e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tools operation. If damaged, have the power tool repaired before use. Many accidents are caused by
poorly maintained power tools.
f ) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
g) 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 intended could result in a hazardous situation.
5) Service
a) 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.

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 paints.
• Crystalline silica from bricks and cement and other
masonry products.
• 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.
1. 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.
2. 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 speed” marked on the tool’s nameplate.
3. 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.
4. 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.
5. 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 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.
6. 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.
7. DO NOT USE DEPRESSED HUB GRINDING WHEELS FOR CUT-OFF OPERATIONS.
8. DO NOT USE THIS TOOL WITH “WOODCARVING” BLADE. Such blades create frequent kick-back and
loss of control.
9. 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.
10. 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.
11. AVOID BOUNCING AND SNAGGING THE WHEEL, ESPECIALLY WHEN WORKING CORNERS, SHARP EDGES ETC. This can cause loss of control and
kick-back.
12. REGULARILY CLEAN THE TOOL’S AIR VENTS BY COMPRESSED AIR. Excessive accumulation of
powdered metal inside the motor housing may cause electrical failures.
13. DO NOT GRIND OR SAND NEAR FLAMMABLE MATERIALS. Sparks from the wheel could ignite these
materials.
14. 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.
15. 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.
16. WHEN SANDING CHEMICALLY PRESSURE TREATED LUMBER, PAINT THAT MAY BE LEAD BASED, OR ANY OTHER MATERIALS THAT MAY CONTAIN CARCINOGENS, USE SPECIAL PRECAUTIONS. A suitable breathing respirator must
be worn by all personal entering the work area. Work area should be sealed by plastic sheeting and persons not protected should be kept out until work area is thoroughly cleaned.
17. DIRECT THE DISCHARGE OF THE SPINNING WIRE BRUSH AWAY FROM YOU. Small particles and tiny
wire fragments may be discharged at high velocity during the “cleaning” action with these brushes and may become imbedded in your skin.

Grinding Tips
The tool is switched “ON” by the switch button located at the top 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.
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.
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.
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.
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 discs are made of extremely hard and sharp aluminum oxide grits, phenol-resin 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.
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.
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.
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.
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.
Wire brushes are intended to “clean” structural steel, castings, sheet metal, stone and oncrete. They are used to remove rust, scale and paint.
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.
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.
Hold the tool with both hands while starting the tool, since torque from the motor can cause the tool to twist.
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.
WARNING!
Excessive or sudden pressure on the wheel will slow grinding action and put dangerous stresses on the wheel.
WARNING!
Avoid bouncing and snaging the wire brush, especially when working corners, sharp edges etc. This can cause loss of control and kick-back.
WARNING!
Operation: Refinishing painted wood or metal surfaces.
