General Power Tool Safety Warnings

WARNING: Read all safety warnings, instructions, illustrations and speciﬁcations provid-ed with this power tool. Failure to follow all instructions listed below 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

a. Keep work area clean and well lit. Cluttered or 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.

Electrical safety

a. Power tool plugs must match the out-let. 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 elec-tric shock.
b. Avoid body contact with earthed or ground-ed surfaces, such as pipes, radiators, rang-es 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 electric 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 reduc-es the risk of electric shock.
f. If operating a power tool in a damp location is unavoidable, use a Ground Fault Circuit Interrupter (GFCI) protected supply. Use of an GFCI reduces the risk of electric shock.

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, alco-hol or medication. A moment of inattention while operating power tools may result in se-rious personal injury.
b. Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat, or hearing protection used for ap-propriate conditions will reduce personal injuries.
c. Prevent unintentional starting. Ensure the switch is in the off-position before connect-ing to 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 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 situ-ations.
f. Dress properly. Do not wear loose cloth-ing or jewelry. Keep your hair and clothing away from moving parts. Loose clothes, jewelry 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 dust collection can reduce dust-related hazards.
h. Do not let familiarity gained from frequent use of tools allow you to become compla-cent and ignore tool safety principles. A careless action can cause severe injury with-in a fraction of a second.

Power tool use and care

a. Do not force the power tool. Use the cor-rect 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 and/or remove the battery pack, if detach-able, from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safe-ty 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 unfamil-iar 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 and accessories. Check for misalignment or binding of mov-ing 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.
f. Keep cutting tools sharp and clean. Prop-erly 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 instruc-tions, taking into account the working con-ditions and the work to be performed. Use of the power tool for
operations different from those intended could result in a haz-ardous situation.
h. Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

Battery tool use and care

a. Recharge only with the charger speciﬁed by the manufacturer. A charger that is suit-able for one type of battery pack may create a risk of ﬁre when used with another battery pack.
b. Use power tools only with speciﬁcally des-ignated battery packs. Use of any other bat-tery packs may create a risk of injury and ﬁre.
c. When battery pack is not in use, keep it away from other metal objects like paper clips, coins, keys, nails, screws, or other small metal objects that can make a con-nection from one terminal to another. Shorting the battery terminals together may cause burns or a ﬁre.
d. Under abusive conditions, liquid may be ejected from the battery, avoid contact. If contact accidentally occurs, flush with wa-ter. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the bat-tery may cause irritation or burns.
e. Do not use a battery pack or tool that is damaged or modiﬁed. Damaged or modiﬁed batteries may exhibit unpredictable behavior resulting in ﬁre, explosion or risk of injury.
f. Do not expose a battery pack or tool to ﬁre or excessive temperature. Exposure to ﬁre or temperature above 265 °F may cause ex-plosion.
g. Follow all charging instructions and do not charge the battery pack or tool outside the temperature range speciﬁed in the instruc-tions. Charging improperly or at tempera-tures outside the speciﬁed range may dam-age the battery and increase the risk of ﬁre.

Service

a. Have your power tool serviced by a quali-ﬁed repair person using only identical re-placement parts. This will ensure that the safety of the power tool is maintained.
b. Never service damaged battery packs. Ser-vice of battery packs should only be per-formed by the manufacturer or authorized service providers.

Safety Warnings Common for Grind-ing, Sanding, Wire Brushing, and Abrasive Cutting-Off Operations

a. This power tool is intended to function as a grinder, sander, wire brush or cut-off tool. Read all safety warnings, instructions, il-lustrations and speciﬁcations provided with this power tool. Failure to follow all in-structions listed below may result in electric shock, ﬁre and/or serious injury.
b. Operations such as polishing are not rec-ommended to be performed with this pow-er tool. Operations for which the power tool was not designed may create a hazard and cause personal injury.
c. Do not use accessories which are not spe-ciﬁcally designed and recommended by the tool manufacturer. Just because the acces-sory can be attached to your power tool, it does not assure safe operation.
d. The rated speed of the accessory must be at least equal to the maximum speed marked on the power tool. Accessories run-ning faster than their rated speed can break and fly apart.
e. 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.
f. Threaded mounting of accessories must match the grinder spindle thread. for ac-cessories mounted by flanges, the arbour hole of the accessory must ﬁt the locating diameter of the flange. Accessories that do not match the mounting hardware of the power tool will run out of balance, vibrate excessively and may cause loss of control.
g. Do not use a damaged accessory. Before each use inspect the accessory such as abrasive wheels for chips and cracks, back-ing 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 acces-sory. After inspecting and installing an ac-cessory, position yourself and bystanders away from the plane of the rotating acces-sory and run the power tool at maximum no-load speed for one minute. Damaged accessories will normally break apart during this test time.
h. Wear personal protective equipment. De-pending on application, use face shield, safety goggles or safety glasses. As ap-propriate, wear dust mask, hearing protec-tors, gloves and workshop apron capable of stopping small abrasive or workpiece fragments. The eye protection must be capable of stopping flying debris generated by vari-ous operations. The dust mask or respirator must be capable of ﬁltrating particles gener-ated by your operation. Prolonged exposure to high intensity noise may cause hearing loss.
i. 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 ac-cessory may fly away and cause injury be-yond immediate area of operation.
j. Hold the power tool by insulated gripping surfaces only, when performing an opera-tion where the cutting accessory may con-tact hidden wiring. Cutting accessory con-tacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
k. Never lay the power tool down until the ac-cessory has come to a complete stop. The spinning accessory may grab the surface and pull the power tool out of your control.
l. 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.
m. Regularly clean the power tool’s air vents. The motor’s fan will draw the dust inside the housing and excessive accumulation of pow-dered metal may cause electrical hazards.
n. Do not operate the power tool near flam-mable materials. Sparks could ignite these materials.
o. Do not use accessories that require liquid coolants. Using water or other liquid cool-ants may result in electrocution or shock. that is entering into the pinch point can dig into the surface of the material causing the wheel to climb out or kickout. 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 un-der these conditions.

Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precau-tions as given below.

a. Maintain a ﬁrm grip on the power tool and position your body and arm to allow you to resist kickback forces. Always use aux-iliary handle, if provided, for maximum con-trol over kickback or torque reaction during start-up. The operator can control torque re-actions or kickback forces, if proper precau-tions are taken.
b. Never place your hand near the rotating ac-cessory. Accessory may kickback over your hand.
c. Do not position your body in the area where power tool will move if kickback occurs. Kickback will propel the tool in direction op-posite to the wheel’s movement at the point of snagging.
d. Use special care when working corners, sharp edges etc. Avoid bouncing and snag-ging the accessory. Corners, sharp edges or bouncing have a tendency to snag the rotat-ing accessory and cause loss of control or kickback.
e. 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

a. Use only wheel types that are recom-mended for your power tool and the spe-ciﬁc guard designed for the selected wheel. Wheels for which the power tool was not de-signed cannot be adequately guarded and are unsafe.
b. The grinding surface of center depressed wheels must be mounted below the plane of the guard lip. An improperly mounted wheel that projects through the plane of the guard lip cannot be adequately protected.
c. The guard must be securely attached to the power tool and positioned for maxi-mum safety, so the least amount of wheel is exposed towards the operator. The guard helps to protect operator from broken wheel fragments, accidental contact with wheel and sparks that could ignite clothing.
d. Wheels must be used only for recommend-ed applications. For example: do not grind with the side of cut-off wheel. Abrasive cut-off wheels are intended for peripheral grind-ing, side forces applied to these wheels may cause them to shatter.
e. Always use undamaged wheel flanges that are of correct size and shape for your se-lected wheel. Proper wheel flanges support the wheel thus reducing the possibility of wheel breakage. Flanges for cut-off wheels may be different from grinding wheel flang-es.
f. Do not use worn down wheels from larger power tools. Wheel intended for larger pow-er tool is not suitable for the higher speed of a smaller tool and may burst.

Additional Safety Warnings Speciﬁc for Abrasive Cutting-Off Operations

a. Do not “jam” the cut-off wheel or apply ex-cessive pressure. Do not attempt to make an excessive depth of cut. Overstressing the wheel increases the loading and susceptibil-ity to twisting or binding of the wheel in the cut and the possibility of kickback or wheel breakage.
b. 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.
c. When wheel is binding or when interrupt-ing a cut for any reason, switch off the pow-er 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.
d. 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.
e. Support panels or any oversized workpiece to minimize the risk of wheel pinching and kickback. 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.
f. Use extra caution when making a “pocket cut” into existing walls or other blind areas. The protruding wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback.
g. Do not use type 1 abrasive wheels designed for straight grinding.
h. Do not attempt to cut large stock or sheets of metal as this machine is not designed to be a dedicated cut-off machine.

Safety Warnings Speciﬁc for Sanding Operations

a. Do not use excessively oversized sanding disc paper. Follow manufacturer’s recom-mendations, 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 Speciﬁc for Wire Brushing Operations

a. Be aware that wire bristles are thrown by the brush even during ordinary operation. Do not overstress the wires by applying ex-cessive load to the brush. The wire bristles can easily penetrate light clothing and/or skin.
b. If the use of a guard is recommended for wire brushing, do not allow any interfer-ence of the wire wheel or brush with the guard. Wire wheel or brush may expand in diameter due to work load and centrifugal forces.

Additional Safpage headingety Warnings

Do not use AC only rated tools with a DC power supply. While the tool may appear to work, the electrical components of the AC rated tool are likely to fail and create a hazard to the operator.
Keep handles dry, clean and free from oil and grease. Slippery hands cannot safely control the power tool.
Use clamps or other practical way to secure and support the workpiece to a stable plat-form. Holding the work by hand or against your body is unstable and may lead to loss of control.
Develop a periodic maintenance schedule for your tool. When cleaning a tool be careful not to disassemble any portion of the tool since internal wires may be misplaced or pinched or safety guard return springs may be improperly mounted. Certain cleaning agents such as gaso-line, carbon tetrachloride, ammonia, etc. may damage plastic parts.
Do not use vacuum or other dust collection system when cutting metal. Sparks from metal cutting can cause ﬁre in the collector.

WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities con-tains chemicals known to cause cancer, birth defects or other reproductive harm. Some ex-amples of these chemicals are:

Lead from lead-based paints,
Crystalline silica from bricks and cement and other masonry products, and
Arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, depend-ing 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 ap-proved safety equipment, such as those dust masks that are specially designed to ﬁlter out microscopic particles.

Functional Descriptions

Kickback Control:
The electronics in the power tool detects situ-ations where the wheel or accessory may be at risk to bind. The electronics prevents further rotation of the drive spindle by switching the power tool off (it does not prevent kickback). To resume operation, turn on/off switch to the off position, then restart tool.

Constant Response Circuitry:
Helps maintain near constant RPMs between no-load and load conditions.

Soft Start:
Helps reduce stress on the motor that occurs from a high torque start. Helps bring accessory smoothly up to speed.

Automatic Restart Protection:
Helps prevent accidental startups after power has been interrupted, e.g. the tool was un-plugged with the switch locked in the on posi-tion. To resume operation, turn on/off switch to the off position, then restart the tool.

Overload Protection:
Helps protect tool from excessive heat that may damage motor. If tool stops or slows during op-eration, allow motor to cool for 30 seconds by running no- load. If the overload protection stops the tool repeatedly, excessive force is causing the tool to overload. Stop excessive force and readjust work piece to reduce force applied.

Drop Control:
The power tool is equipped with sensors that detect impact to the grinder. The tool will turn off if it is dropped on most hard surfaces from height greater than one foot, or hit with force ap-proximately equivalent to more than a one foot drop. After any impact or activation of the shut off feature, always inspect the grinder and the battery for signs of damage and do not use the tool or the battery if any damage is suspected.

Brake Operation

WARNING: Let the grinder accessory come to a complete stop be- fore setting the tool down. The brake action of this grinder is not intended as a safety feature. Using the appropriate guard when operating the grinder is your best protection against uninten-tional contact with a spinning accessory. Unin-tended contact with a rotating accessory can cause property damage and\or personal injury. Know the charge state of your battery. The electric braking action is initiated ONLY by the release of the trigger switch and in a tool that has pow-er available. When electrical power is lost due to a discharged battery or other causes, the electric brake will not operate and the motor will gradually slow down. Unexpected run down time may cause property damage and/or per-sonal injury.

Your grinder is equipped with an automatic elec-tric brake which is designed to rapidly stop the accessory from spinning after you release the trigger switch. This feature helps improve job-site productivity.
Braking starts once the power is turned off. The brake requires a charged battery to function. Stopping time will vary depending on, among other factors, accessory used, and number of actuations.
The electric brake of your grinder has been designed for a high degree of reliabil-ity, but unexpected circumstances such as con-tamination or failure of the motor’s components can cause the brake to not activate. If the tool operates but the brake does not consistently stop the accessory, DO NOT use the grinder and have it serviced by a Bosch Factory Service Cen-ter or Bosch authorized service facility.

Inserting and Releasing Battery Pack

This tool is equipped with Automatic Restart Protection. This feature helps prevent acciden-tal startups after power has been interrupted, e.g. the battery was removed with the switch locked in the on position. To resume operation, turn the side switch to the off position, and back to on position to restart the tool.
Make sure that the Side Switch (Fig. 14, 2a) is in the off position before inserting or removing battery pack. To insert the battery pack slide it into the housing until the battery pack locks into position.
Your tool is equipped with a secondary locking latch to prevent the battery pack from complete-ly falling out of the handle, should it become loose due to vibration.
To remove the battery pack, press the battery pack release button and slide the battery pack forward.
Press the battery pack release button again and slide the battery pack completely out of tool housing (Fig. 13).

Operating Instructions

WARNING: Never leave the trigger locked “ON”. Before plug- ging the tool in, check that the trigger lock is “OFF”. Accidental start-ups could cause injury. Be aware of the location and setting of the switch “Lock-ON” button. If the switch is locked “ON” during the use, be ready for emergency situations to switch it “OFF”. Do not use the switch “Lock- ON” feature in situations where kickback is likely, such as when working into a corner. When the wheel binds, the tool will kick-back in opposite direction of wheel ro-tation and the release of the trigger “Lock-ON” may be difficult. 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 contact-ing 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.\

Side Switch with LockON

To turn tool ON:
Press the back of the Side Switch (Fig. 14, 2a) and slide it forward towards the gear housing until it comes to a stop and the motor starts run-ning.
For Lock-ON, when the Side Switch (2a) is in the ON position, press the front of the Side Switch and release it. the Side Switch should remain in the Lock- ON position and the tool will continue to run.

To turn tool OFF:
Press the rear portion of the Side Switch (2a). The Side Switch is spring loaded and will return to the OFF position automatically.

Grinding

SELECTING GRINDING WHEELS
Before using a grinding wheel, be certain that its maximum safe operating speed is not exceed-ed by the nameplate speed of the grinder. Do not exceed the recom mended wheel diameter.

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 grind-ing wheels for fast grinding of structural steel, heavy weld beads, steel casting, stainless steel and other ferrous metals.

Allow the tool to reach full speed before touching the tool to the work surface.
Apply minimum pressure to the work sur-face, allowing the tool to operate at high speed. Grinding rate is greatest when the tool operates at high speed.
Maintain a 10° to 15° angle between the tool and work surface, (Fig. 16).
Continuously move the tool at a moderate speed to avoid creating gouges in the work surface.
Remove the tool from work surface before turning tool off. Allow the tool to stop rotat-ing before laying it down.

WARNING: Excessive or sudden pres-sure 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 work piece when pushing forward.

Cutting

METAL CUTTING
WARNING: A Type 1A/41 wheel guard may not be included with this tool but is required when using a cutting wheel. Cutting with a type 27 wheel guard may not provide the operator sufficient protection in the event of a wheel burst With this grinder it is possible to perform cut-ting of limited small stock such as metal tubes, piping or rebar. When cutting, work with mod-erate feed, adapted to the material being cut. When cutting proﬁles and square bar, it is best to start at the smallest cross section. Always follow precautions for kickback.

Allow the tool to reach full speed before touching the tool to the work surface.
The tool should always be used in such way that the sparks are directed away from user.
Apply minimum pressure to the work sur-face, allowing the tool to operate at high speed. Cutting rate is greatest when the tool operates at high speed.
Do not exert side pressure onto the cutting disc. Do not tilt or oscillate the tool as wheel may burst, (Fig. 17).
Remove the tool from the work surface be-fore turning the tool off. Allow the tool to stop rotating before laying it down.

MASONRY / CONCRETE CUTTING

WARNING: Never pull the tool back- ward, since blade will climb out of the material and KICKBACK, will occur. With this grinder it is possible to perform cut-ting of concrete and masonry materials. When cutting, work with moderate feed, adapted to the material being cut. Always follow precautions for kickback. Operate the tool with a dust extraction system and personal dust protection, e.g. respirator, dust mask, etc. The vacuum used for this appli- cation must be approved for the extraction of masonry and concrete dust. Bosch sells suitable vacuum cleaners.

Allow the tool to reach full speed before touching the tool to the work surface.
If plunge cutting:
a. Tilt tool forward with wheel lined up with the cut line and hold the tool by the grinder body and the auxiliary handle (Fig. 18).
b. Gradually lower the rear of tool using the front end of the foot as the hinge point.
c. When the foot rests flat on the surface being cut, proceed cutting in forward di-rection to end of cut.
Always maintain contact between the guard foot and work piece.
Slide the tool forward at a moderate speed adapted to the material being cut. Always cut towards the dust extraction port to maxi-mize dust extraction and reduce likelihood of kickback (Fig. 19).
Apply minimum pressure to the work sur-face, allowing the tool to operate at high speed. Cutting rate is greatest when the tool operates at high speed.
When the cut is completed, remove tool from work piece before turning off. Allow wheel to stop rotating before setting tool down.

Tip: When performing deep cuts, it is best to cut in several shallow passes. Each pass should be only to the segment depth of the wheel. Ma-sonry dust is abrasive and may wear and weaken the segment bond.When cutting especially hard material, e. g., concrete with high pebble content, the dry diamond wheel can overheat and become damaged. This is clearly indicated by circular sparking of the rotating dry diamond wheel. In this case, interrupt the cutting process and allow the dry diamond wheel to cool by running the tool for a short period of time at the maximum speed with no-load.
Noticeable decreasing work progress and circular sparking are indications of a dry diamond wheel that has become dull. Briefly cutting into abrasive materials (e. g. brick) can resharpen the wheel.

CONCRETE SURFACING
Operate the tool with a dust extraction system and personal dust protection, e.g. respirator, dust mask, etc. The vacuum used for this application must be approved for the extraction of masonry and concrete dust. Bosch sells suitable vacuum cleaners.

Diamond cup wheels should be carefully selected in order to use the grinder most efficiently. Wheels vary in type of material they are designed to remove and how aggressively they will remove material. The correct wheel to use is determined by the job.

Allow the tool to reach full speed before touching the tool to the work surface.
Hold the tool with two hands and keep dia-mond wheel flat on the work surface.
Apply minimum pressure, allowing the tool to operate at high speed. Removal rate is great-est when the tool operates at high speed.
Continuously move the tool at a moderate speed to avoid creating gouges in the work surface.
Remove the tool from work surface before turning tool off. Allow the tool to stop rotat-ing before laying it down.

Tip: For optimal dust collection, all sides of the surfacing dust collection guard must stay in con-tact with the surface and the surfacing guard must be connected to a vacuum. A dull diamond wheel can be sharpened by briefly surfacing an abrasive material (eg. sand stone).

Sanding: Sanding discs range in grit from 16 (very course) to 180 (very ﬁne). They also vary in size and spacing of grit. OPEN COAT (type H) is used for soft materials and on paint and varnish, CLOSED COAT (type K) is used for metal, hardwood, stone, marble and other materials. To obtain best results, se-lect 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 complete the job. See chart for application examples.

Allow the tool to reach full speed before touching the tool to the work surface.
Apply minimum pressure to the work sur-face, allowing the tool to operate at high speed. Sanding rate is greatest when the tool operates at high speed.
Maintain a 10° to 15° angle between the tool and work surface, (Fig. 20).
WARNING: If the disc (accessory) is held flat or the back edge of the disc comes in contact with the work, a vio-lent thrust to the side may result.
Continuously move the tool at a moderate speed to avoid creating gouges in the work surface.
Remove the tool from work surface before turning tool off. Allow the tool to stop rotat-ing before laying it down.

Tip: Guide the disc with crisscross strokes. Do not use a circular motion as this makes swirl marks.

Operation: Refinishing painted wood or metal surfaces.

Operation: Refinishing painted wood or metal surfaces.

REMARKS| GRIT
To remove paint and to smooth surface irregularities.| Coarse 16-24-30
To smooth the rough sanding.| Medium 36-50-80
To remove scratches left by previous discs.| Fine 100-120
To smooth surfaces for painting, polishing or waxing.| Very Fine 150-180

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 occa-sionally create generally prohibit their use for producing the ﬁnal ﬁnish.Scratches and circular marks are usually the re- sult of using too coarse a grit. When changing to a ﬁner grit, move across the sand ing 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 scratch-es. To produce smooth ﬁnish, use ﬁne grit disc.

Wire Brush Operations

WARNING: Avoid bouncing and snagging the wire brush, espe- cially when working corners, sharp edges etc. This can cause loss of control and kick- back. Wire brushes are intended to “clean” structural steel, castings, sheet metal, stone and concrete. They are used to remove rust, scale and paint.

BRUSHING PRESSURE

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.
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.
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.
