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 “AC only” 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"

-2-

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 “OFF” 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 “ON”. 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 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.

BM 2609931631 9/00 2/14/01 4:42 PM Page 3

Do not use tool if switch does not turn it “ON” or “OFF”. 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.

Belt Sander Safety Rules

Hold tool by insulated gripping surfaces when performing a operation where the cutting tool 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.

If your tool is equipped with a dust bag, empty it frequently and after completion of sanding. Be extremely careful of dust disposal, materials in fine particle form may be explosive. Do not throw sanding dust on an open fire. Spontaneous combustion, may in time, result from mixture of oil or water with dust particles.

Always wear eye protection and a dust mask for dusty applications and when sanding overhead. Sanding particles can be absorbed by your eyes and inhaled easily and may cause health complications.

Use special precautions when sanding chemically pressure treated lumber, paint that may be lead based, or any other materials that may contain carcinogens. A suitable breathing respirator and protective clothing must be worn by all persons

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.

Do not wet sand with this sander. Liquids entering the motor housing is an electrical shock hazard.

Never leave the trigger locked “ON”. Before plugging the tool in, check that the trigger lock is “OFF”. Accidental start-ups could cause injury.

Unplug the sander before changing accessories. Accidental start-ups may occur if sander is plugged in while changing an accessory.

Keep your fingers and clothing away from the belt. They could get cut or wedged between the pulley, belt and motor housing.

Properly adjust tracking of belt to avoid it overhanging the housing. A running belt overhanging its housing can cause severe lacerations.

Be aware of the location and setting of the Switch "Lock-ON"Button.If the switch

-3-

! WARNING

BM 2609931631 9/00 2/14/01 4:42 PM Page 4

is locked "ON", be ready for emergency situations to switch it "OFF", by first pulling the trigger then immediately releasing it without pressing the "Lock-ON"button.

Keep the cord to the side away from pulleys. The cord can be dragged into belt housing and become entangled with the pulleys.

Clamp or secure workpiece when sanding. Clamping the workpiece prevents it from being ejected from under the sander and leaves both hands to control the tool.

Clamp or secure sander if it is inverted and bench mounted for use as a table sander. Always use edge stop or guide when sanding short or small workpieces.

Fingers or clothing can be dragged into pulley and housing area.

Portable belt sanders are not intended to be permanently mounted as a bench or table sander. There are accessories available which can convert certain portable belt sanders for occasional stationary use. If such accessories are used always clamp or secure sander when inverted and bench mounted

-4-

for use as a table sander. Be aware of switch location and know how to shut off the tool in emergency situations. Always follow directions included with the accessory. Use sanding fence, stop or guide when sanding short or small workpieces.

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-basedpaints,

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.

BM 2609931631 9/00 2/14/01 4:42 PM Page 8

Turn tool on and place the complete sanding surface on the workpiece to achieve uniform material removal. Work with moderate forward motion. Perform the sanding movements with parallel and overlapping passes. Sand in the direction of the grain; crossways sanding can result in uneven finishes.

As a result of the high removal rate, only light application pressure should be used while working to prevent damage to workpiece.

When sanding corner frames (e.g., interior corners), always move forward only so far that the sanding belt does not come in contact with the side that is vertical to the workpiece.

FLUSH SANDING

Your sander has been designed to allow convenient flush sanding on the right side of the sander, however your sander can be used on either surface by simply turning the tool upside down. This unique design allows flush sanding on the right and left sides of a workpiece.

ATTENTION: When the tool is being used upside down belt will rotate the opposite direction, and the dust collection system will not work.

Only flawless sanding belts produce good sanding results and protect the tool. Do not continue to use worn out, torn or heavily clogged sanding belts.

To increase belt life, apply uniform pressure. Increasing pressure does not improve sanding performance, but increases wear to the tool and the sanding belt.

Do not sand wood and metal with the same sanding belt.

Use only original Bosch sanding belts and accessories.

Maintenance

Service

Preventive maintenance performed by unauthorized personnel may result in misplacing of

internal wires and components which could cause serious hazard. We recommend that all tool service be performed by a Bosch Factory Service Center or Authorized Bosch Service Station.

TOOL LUBRICATION

Your Bosch tool has been properly lubricated and is ready to use. It is recommended that tools with gears be regreased with a special gear lubricant at every brush change.

CARBON BRUSHES

The brushes and commutator in your tool have been engineered for many hours of dependable service. To maintain peak efficiency of the motor, we recommend every two to six months the brushes be examined. Only genuine Bosch replacement brushes specially designed for your tool should be used.

BEARINGS

After about 300-400hours of operation, or at every second brush change, the bearings

should be replaced at Bosch Factory Service Center or Authorized Bosch Service Station. Bearings which become noisy (due to heavy load or very abrasive material cutting) should be replaced at once to avoid overheating or motor failure.

Cleaning

! WARNING To avoid accidents always disconnect the tool from the

power supply before cleaning or performing any maintenance. The tool may be cleaned most effectively with compressed dry air.

Always wear safety goggles when cleaning tools with compressed air.

Ventilation openings and switch levers must be kept clean and free of foreign matter. Do not attempt to clean by inserting pointed objects through openings.

!

CAUTION

Certain cleaning agents and

solvents damage plastic

 

 

parts. Some of these are: gasoline, carbon tetrachloride, chlorinated cleaning solvents, ammonia and household detergents that contain ammonia.

Accessories

If an extension cord is necessary, a cord with adequate size conductors that is capable

of carrying the current necessary for your tool must be used. This will prevent excessive voltage drop, loss of power or overheating. Grounded tools must use 3- wire extension cords that have 3-prong plugs and receptacles.

NOTE: The smaller the gauge number, the heavier the cord.

Règles de Sécurité Générales

 

!

 

Vous devez lire et comprendre toutes les instructions. Lenon-respect, même

 

 

partiel, des instructions ci-aprèsentraîne un risque de choc életrique, d'incendie

et/ou de blessures graves.

CONSERVEZ CES INSTRUCTIONS

 

 

 

Aire de travail

Veillez à ce que l'aire de travail soit propre et bien éclairée. Le désordre et le manque de lumière favorisent les accidents.

N'utilisez pas d'outils électriques dans une atmosphère explosive, par exemple enprésence de liquides, de gaz ou de poussières inflammables. Les outils électriques créent des étincelles qui pourraient enflammer les poussières ou les vapeurs.

Tenez à distance les curieux, les enfants et les visiteurs pendant que vous travaillezavec un outil électrique. Ils pourraient vous distraire et vous faire faire une fausse manoeuvre.

Sécurité électrique

Les outils à double isolation sont équipés d'une fiche polarisée (une des lames est pluslarge que l'autre), qui ne peut se brancher que d'une seule façon dans une prise polarisée. Si la fiche n'entre pas parfaitement dans la prise, inversez sa position ; si elle n'entre toujours pasbien, demandez à un électricien qualifié d'installer une prise de courant polarisée. Ne modifiez pas la fiche de l'outil. La double isolation élimine le besoin d'un cordon d'alimentationà trois fils avec mise à la terre ainsi que d'une prise de courant mise à la terre. Avant de brancher l'outil, assurez-vous que la tension de la prise correspond, à celle indiquée sur la plaque signalétique. N'utilisez pas d'outils prévus pour courant alternatif seulement avec une source de courant continu.

Évitez tout contact corporel avec des surfaces mises à la terre (tuyauterie, radiateurs, cuisinières, réfrigérateurs, etc.). Le risque de choc électrique est plus grand si votre corps est encontact avec la terre.Si l'utilisation de l'outil électrique dans un endroit humide est inévitable, un disjoncteur de fuite à la terre doit être utilisé pour alimenter votre outil. Des chaussures et des gants en caoutchouc d'électricien contribueront à accroître davantage votre sécurité personnelle.

N'exposez pas les outils électriques à la pluie ou à l'eau. La présence d'eau dans un outil électrique augmente le risque de choc électrique.

Ne maltraitez pas le cordon. Ne transportez pas l'outil par son cordon et ne débranchez pas la fiche en tirant sur le cordon. N'exposez pas le cordon à la chaleur, à des huiles, à des arêtes vives ou à des pièces en mouvement. Remplacez immédiatement un cordon endommagé. Un cordon endommagé augmente le risque de choc électrique.

Lorsque vous utilisez un outil électrique à l'extérieur, employez un prolongateur pour l'extérieur marqué « W-A» ou « W ».Ces cordons sont faits pour être utilisés à l'extérieur et réduisent le risque de choc électrique. Reportez-vous aux « Dimensions recommandées des cordons de rallonge » dans la section Accessoires de ce manuel.

Sécurité des personnes

Restez alerte, concentrez-voussur votre travail et faites preuve de jugement. N'utilisez pas un outil électrique si vous êtes fatigué ou sous l'influence de drogues, d'alcool ou de médicaments.Un instant d'inattention suffit pour entraîner des blessures graves.

Habillez-vousconvenablement. Ne portez ni vêtements flottants ni bijoux. Confinez les cheveux longs. N'approchez jamais les cheveux, les vêtements ou les gants des pièces en mouvement.

Des vêtements flottants, des bijoux ou des cheveux longs risquent d'être happés par des pièces en mouvement. Gardez les poignées sèches, propres et exemptes d'huile et de graisse.

Méfiez-vousd'un démarrage accidentel. Avant de brancher l'outil,assurez-vousque son interrupteur est sur ARRÈT.Le fait de transporter un outil avec le doigt sur la détente ou de brancher un outil dont l'interrupteur est en position MARCHE peut mener tout droit à un accident.

Enlevez les clés de réglage ou de serrage avant de démarrer l'outil. Une clé laissée dans une pièce tournante de l'outil peut provoquer des blessures.

Ne vous penchez pas trop en avant. Maintenez un bon appui et restez en équilibre entout temps. Un bonne stabilité vous permet de mieux réagir à une situation inattendue.

Utilisez des accessoires de sécurité. Portez toujours des lunettes ou une visière. Selon les conditions, portez aussi un masque antipoussière, des bottes de sécurité antidérapantes, un casque protecteur et/ou un appareil antibruit.

Utilisation et entretien des outils

Immobilisez le matériau sur une surface stable au moyen de brides ou de toute autre façon adéquate.

Le fait de tenir la pièce avec la main ou contre votre corps offre une stabilité insuffisante et peut amener un dérapage de l'outil.

Ne forcez pas l'outil. Utilisez l'outil approprié à la tâche. L'outil correct fonctionne mieux et de façon plus
