Do not 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 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.

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.

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

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.

injury.

SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE

The term “power tool” in the warnings refers to your mains-operated (corded) power tool battery-operated (cordless) power tool.

Work area safety

Keep work area clean and well lit. Cluttered or 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 children and bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical safety

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.

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.

WARNING indicates a hazardous situation which, if not avoided, will result in death or serious injury.

CAUTION, used with the safety alert symbol, indicates a hazardous situation which, if not avoided, will result in minor or moderate injury.

General Power Tool Safety Warnings

Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious

Safety Symbols

or

Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

Prevent unintentional starting. Ensure the switch is in the off-position before connecting 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.

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.

Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.

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 dustrelated hazards.

Power tool use and care

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.

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.

Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.

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.

Maintain power tools. Check for misalignment or binding of moving 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.

Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.

Service

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.

Safety Rules for Oscillating Tools

Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.

Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body leaves it unstable and may lead to loss of control.

Do not drill, fasten or break into existing

walls or other blind areas where electrical wiring may exist. If this situation is unavoidable, disconnect all fuses or circuit breakers feeding this worksite.

Use a metal detector to determine if there are gas or water pipes hidden in the work area or call the local utility company for assistance before beginning the operation.

Striking or cutting into a gas line will result in explosion. Water entering an electrical device may cause electrocution.

Always hold the tool firmly with both hands for maximum control. Keep proper footing and balance at all times. This enables better

control of the power tool in unexpected situations.

Keep hands away from cutting area. Do not reach under the material being cut. The proximity of the blade to your hand is hidden from your sight.

Do not use dull or damaged blades. Bent blade can break easily or cause kickback.

Exercise extreme caution when handling the accessories. The accessories are very sharp.

Wear protective gloves when changing cutting accessories. Accessories become hot after prolonged usage.

Use thick cushioned gloves and limit the exposure time by taking frequent rest periods. Vibration caused by the tool may be harmful to the hands and arms.

Before scraping, check workpiece for nails. If there are nails, either remove them or set them well below intended finished surface.

Striking a nail with accessory edge could cause the tool to jump.

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

Never work in area which is soaked with a

liquid, such as a solvent or water, or dampened such as newly applied wallpaper. There is an electrical shock hazard when working in such conditions with a power tool and heating of the liquid caused by scraping action may cause harmful vapors to be emitted from workpiece.

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 use sandpaper intended for larger sanding pads. Larger sandpaper will extend beyond the sanding pad causing snagging, tearing of the paper or kick-back. Extra paper extending beyond the sanding pad can also cause serious lacerations.

Additional Safety Warnings

Always inspect accessories for damage (breakage, cracks) before each use. Never use if damage is suspected.

GFCI and personal protection devices like electrician’s rubber gloves and footwear will further enhance your personal safety.

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.

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 gasoline, carbon tetrachloride, ammonia, etc. may damage plastic parts.

Risk of injury to user. The power cord must only be serviced by a Bosch Factory Service Center or Autho rized Bosch Service Station.

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.

VARIABLE SPEED DIAL

This tool is equipped with a variable speed dial. The speed may be controlled during operation by presetting the dial in any one of six positions (Fig. 1).

OPERATING SPEEDS

The Bosch oscillating tools have a high oscillating motion of 8,000 - 20,000 /min (OPM). The high speed motion allows the Bosch tools to achieve with excellent results. The oscillating motion allows the dust to fall to the surface rather than slinging particles into the air.

To achieve the best results when working with different materials, set the variable speed control to suit the job (see Speed Range chart at right for guidance). To select the right speed for the accessory in use, practice with scrap material first.

NOTE: Speed is affected by voltages changes. A reduced incoming voltage will slow the OPM of the tool, especially at the

lowest setting. If your tool appears to be
running slowly, increase the speed setting
accordingly. The tool may not start at the
lowest switch setting in areas where outlet
voltage is less than 120 volts. Simply move
the speed setting to a higher position to
begin operation.
The variable speed control settings are
marked on the speed control dial. The
settings for approximate /min (OPM) are:
Speed Dial	Speed Range

Common Applications

For all accessories, work from the body. with the accessory away

Never position hand near or directly in front of working area. Always hold the tool with both hands and wear protective gloves.

Below are some typical uses for your Bosch oscillating tool.

Flush Cutting

Remove excess wood from door jamb, window sill and/or toekick. Removing excess copper or PVC pipe.

Removal work

e.g. carpets & backing, old tile adhesives, caulking on masonry, wood and other surfaces.

Removal of excess materials

e.g. plaster, mortar splatters, concrete on tiles, sills.

Preparation of surfaces e.g. for new floors and tiles.

Detail sanding

e.g. for sanding in extremely tight areas otherwise difficult to reach and require hand sanding

CUTTING

Saw blades are ideal for making precise cuts in tight areas, close to edges or flush to a surface.

Select a medium to high speed for making initial plunge, start off at medium speed for increased control. After making your initial cut, you can increase speed for faster cutting ability. Flush cutting blades are

intended to make precise cuts to allow for installation of flooring or wall material. When flush cutting

it is important not to force the tool during the plunge cut. If you experience a strong vibration in your hand during the plunge cut, this indicates that you are applying too much pressure. Back the tool out and let the speed of the tool do the work. While keeping the teeth of the blade in the work surface, move the back of the tool in a slow sideways motion. This motion will help expedite the cut.

When making a flush cut it is always a good idea to have a piece of scrap material (tile or

wood) supporting the blade. If you need to rest the flush cutting blade on a delicate surface, you should protect the surface with cardboard or masking tape.

The segment saw blade is ideal for making precise cuts in wood, plaster, drywall material.

s include cutting openings in flooring for venting, repairing damaged flooring, cutting openings for electrical boxes. The blade works best on softer woods such as pine. For harder woods, the blade life will be limited.

Select a medium to high speed.

GROUT REMOVAL

Grout removal blades are ideal for removing damaged or cracked grout. Grout blades come in different widths (1/16"

and 1/8") to tackle different grout line widths. Before selecting a grout blade measure the grout line width to pick the appropriate blade.

Select a medium to high speed.

To remove the grout, use a back and forth motion, making several passes along the grout line. The hardness of the grout will dictate how many passes are needed. Try and keep the grout blade aligned with the grout line and be careful not to apply too much side pressure on the grout blade during the process. To control plunge depth use the carbide grit line on the blade as an indicator. Be careful not to plunge beyond the carbide grit line to avoid damage to the backer board material.

The grout blades can handle both sanded and unsanded grout. If you notice the blade clogging during the grout removal process, you can use a brass brush to clean the grit, thus exposing the grit again.

The grout blade geometry is designed so that the blade can remove all grout up to the surface of a wall or corner. This can be accomplished by ensuring that the segmented portion of the blade is facing the wall or corner.

SCRAPING

Scrapers are suitable for removing old coats of varnish or adhesives, removing bonded carpeting, e.g. on stairs/steps and other small/medium size surfaces.

Select low to medium speed.

Rigid scrapers are for large area removal, and harder materials such as vinyl flooring, carpeting and tile adhesives. When

removing strong, tacky adhesives, grease the scraper blade surface with (petroleum jelly or silicone grease) to reduce gumming up.

The carpet/vinyl flooring removes easier if it is scored prior to removal so the scraper blade can move underneath the flooring material.

Flexible scrapers are used for hard to reach areas and softer material such as caulk.

craper blade with the logo side facing up. With the flexible scraper, make sure that the screw head does not make contact with surface during the scraping process (a 30 - 45 degree pitch is recommend). This can be accomplished by making sure that the tool is at an angle to the blade. You should be able to see the blade flex during the scraping process. If you are removing caulk from a delicate surface such as a bath tub or tile back splash, we recommend taping or protecting the surface that the blade will rest on. Use rubbing alcohol to clean the surface after the caulk and/or adhesive is removed.

Turn the tool on and place desired accessory on the area where material is to be removed. Begin with light pressure. The oscillating motion of accessory only occurs when pressure is applied to the material to be removed.

Excessive pressure can gouge or damage the background surfaces (e.g,. wood, plaster).

SANDING

Sanding accessories are suitable for dry sanding of wood, metal, surfaces, corners and edges and

hard to reach areas.

Work with the complete surface of the sanding pad, not only with the tip.

Corners may be finished using the tip or edge of the selected accessory, which should occasionally be rotated during use to distribute the wear on the accessory and backing pad surface.

Sand with a continuous motion and light
pressure. DO NOT apply excessive pressure -
let the tool do the work. Excessive pressure
will result in poor handling, vibration, and
unwanted sanding marks and premature wear
on the sanding sheet.
Always be certain that smaller workpieces are
securely fastened to a bench or other support.
Larger panels may be held in place by hand on
a bench or sawhorses.
Open-coat aluminum oxide sanding sheets are
recommended for most wood or metal sanding
applications, as this synthetic material cuts
quickly and wears well. Some applications,
such as metal finishing or cleaning, require
special abrasive pads which are available from
your dealer. For best results, use Bosch
sanding accessories which are of superior
quality and are carefully selected to produce
professional quality results with your oscillating
tool.
The following suggestions may be used as a
general guide for abrasive selection, but the
best results will be obtained by sanding a test
sample of the workpiece first.
Grit	Application
Coarse	For rough wood or metal
	sanding, and rust or old
	finish removal.
Medium	For general wood or metal
	sanding
Fine	For final finishing of wood,
	metal, plaster and other
	surfaces.

With the workpiece firmly secured, turn tool on as described above. Contact the work with the tool after the tool has reached its full speed, and remove it from the work before switching the tool off. Operating your oscillating tool in this manner will prolong switch and motor life, and greatly increase the quality of your work.

Move the oscillating tool in long steady strokes parallel to the grain using some lateral motion to overlap the strokes by as much as 75%. DO NOT apply excessive pressure - let the tool do the work. Excessive pressure will result in poor handling, vibration, and unwanted sanding marks.

SANDING TECHNIQUES

CORRECT: Sand with a smooth back and forth motion, allowing the weight of the tool to do the work.

INCORRECT: Avoid sanding with only the tip of the pad. Keep as much sand paper in touch with the work surface as possible.

CORRECT: Always sand with the pad and sandpaer flat against the work surface. Work smoothly in a back and forth motion.

INCORRECT: Avoid tipping the pad. Always sand flat.

CUTTING TECHNIQUES	FIG. 6

CORRECT: Always cut with a smooth back and forth motion. Never force the blade. Apply light pressure to guide the tool.

INCORRECT: Do not twist the tool while cutting.This can cause the blade to bind.

SCRAPING TECHNIQUES

CORRECT: Make sure flexible scraper blade flexes enough

INCORRECT: Avoid screw head touching surface with flexible scraper blade.
