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 us e any a dapte r plug s wit h eart h ed (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.

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 us e common se nse wh en ope rat ing 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.

General Power Tool Safety Warnings

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 sw itc h is in the off-position before connecting to power source and / or battery pa ck, p ick ing u p or carrying th e too l.

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

co ntro l o f t he pow e r tool in un expe cted 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 dust-

related hazards.

Power tool use and care

Do not for ce t he powe r to ol. 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

ca n not be con t roll e d wit h the swit c h 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.

Ma n y accid ents are cau s ed by poo r ly 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.

Battery tool use and care

Recharge only with the charger specified by t he manufacture r. A charg er that is

suitable for one type of battery pack may create a risk of fire when used with another battery pack.

Use power tools only with specifically designated battery packs. Use of any other

battery packs may create a risk of injury and fire.

When battery pack is not in use, keep it away from other metal objects like paper clips, coins, keys, nails, screws, or other sma l l meta l objec t s tha t can make a connection from one terminal to another.

Shorting the battery terminals together may cause burns or a fire.

Under abusive conditions, liquid may be ejected from the battery, avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the

battery may cause irritation or burns.

Service

Have your power tool serviced by a qualified re p air pe r son us i ng onl y ident ical replacement parts. This will ensure that the

safety of the power tool is maintained.

Hold power t ool by insulate d gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring. 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 wi ring may exi st. If thi s si tuat ion 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

co ntro l o f t he pow e r tool in un expe cted 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 expo sure ti me by taking frequ ent res t 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 wi th this tool. Liquid s entering the motor housing is an electrical shock hazard.

Never work in area which is soaked with a li quid , such a s a s olve nt or wa ter, o r da mpen ed s uch as newl y appl ied wall paper. T here is a n electric al shoc k

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 applic ations 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 th at may be le ad base d, or any o t her 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 sh ould be kept o ut unti l w ork 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.

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 y ou r tool. When cleaning a tool be careful not to disassemble any portion of th e tool since inte rna l wire s may be misplaced or pinched or safety guard return sp rin gs may be improperly mo unt ed.

Certain cleaning agents such as gasoline, carb on t etrachloride , am monia , et c. m ay 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 creat ed by

power sanding, sawing, grinding, drilling, and other construction activit ies contains chemicals known to ca use canc er, b irth de f ects or ot h er 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 chemically-

treated lumber.

Yo u r r i sk f rom thes e ex p osur e s v a ries , depending on how often you do this type of work . To re duce your expo sure to thes e 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.

After considerable service the backing pad surface will become worn, and the backing pad must be replaced when it no longer offers a firm

grip. If you are experiencing premature wear out of the backing pad facing, decrease the amount of pressure you are applying during operation of the tool.

For maximum use of abrasive, rotate pad 120 degrees when tip of abrasive becomes worn.

INTENDED USE

This Bosch Oscillating Tool is intended for dry sanding of surfaces, corners, edges, for scraping, for sawing soft metals, wood and

plastic components, and for grout removal using the applicable tools and accessories recommended by Bosch.

Introduction

Operating Instructions

LEARNING TO USE THE TOOL

Getting the most out of your oscillating tool is a matter of learning how to let the speed and the feel of the tool in your hands work for you.

The first step in learning to use the tool is to get the “feel” of it. Hold it in your hand and feel its weight and balance (Fig. 4). Depending on the application, you will need to adjust your hand position to achieve optimum comfort and control. The unique comfort grip on the body of the tool allows for added comfort and control during use.

When holding tool, do not cover the air vents with your hand. Blocking the air vents could cause the motor to overheat.

IMPORTANT! Practice on scrap material first to s ee how th e tool ’s hig h-s peed a ctio n performs. Keep in mind that your tool will perform best by allowing the speed, along with the correct accessory, do the work for you. Be careful not to apply too much pressure.

Instead, lower the oscillating accessory lightly to the work surface and allow it to touch the point at which you want to begin. Concentrate on guiding the tool over the work using very litt le pres sure from y our han d. Allow th e accessory to do the work.

Usually it is better to make a series of passes with the tool rather than to do the entire job with one pass. To make a cut, for example, pass the tool back and forth over the work. Cut a little material on each pass until you reach the desired depth.

SLIDE "ON/OFF" SWITCH

The tool is switched "ON" by the slide switch located on the topside of the motor housing (Fig. 1).

TO TURN THE TOOL "ON" slide the switch button forward to the “I” .

TO TURN THE TOOL "OFF" slide the switch button backward the “0”.

ELECTRONIC FEEDBACK

Yo ur to ol is equ ippe d wit h an i nte rnal electronic feedback system that provides a “soft start”, which will reduce the stresses that occur from a high torque start. The system also helps to keep the preselected speed virtually constant between no-load and load conditions.

BUILT IN WORK LIGHT

Model GOP18V-28 is equipped with an LED work light that turns on automatically when the switch is activated (Fig. 1).

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 s

ix positions (Fig. 1).

OPERATING SPEEDS

Th e Bosc h o sci lla ting t ools h ave a hig h oscillating moti on 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 di ffe rent mat erials, set the variable speed contro l to suit the job (see Speed Range chart at right for guidance). To select the right speed f or the accessory in use, practice with scrap material first.

For all accessories, work with the accessory away

from the body. 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, ca ulki ng on mason ry, 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. f or sand ing in extre mely ti ght are as 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.

Fl ush cu t tin g blade s 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 y our ha nd during t he plu nge c ut, th is indicates t ha t you are applying to o 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.

Ap pli cat ions i ncl ude c utting op eni ngs in fl oori ng fo r ven tin g , re p air ing damag ed 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 fo r rem ovin g dam aged o r 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 un sand ed gro ut. If y ou not ice th e blad e 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 gro ut u p to the su rfa ce of a wa ll or c orner. Th is ca n 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 va rnis h o r a dhe sive s, remo ving bo nded carp eting, e.g . on stai rs/steps a nd othe r small/medium size surfaces.

Select low to medium speed.

Rigid scrapers are for large area removal, and harder materials such as vinyl flooring, carpeting an d ti le a dhes ives . Wh en

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.

Mount the scraper 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 re comm end tap ing or pro tect ing 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 pres su re. The oscillatin g mo tion of acc esso ry only oc curs wh e n pres sure is app lied to the m ateri al 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 sele cte d accessor y, wh ich should occasionally be rotated during use to distribute the wear on the accessory and backing pad surface.

Sand with a conti nuous motion and l ight 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.
