General Power Tool Safety Warnings

WARNING
Read all safety warnings and all instructions. Failure to follow the warnings and instructions 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

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.
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 and 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 residual current device (RCD) protected supply. Use of an RCD 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 op-erating power tools may result in serious personal injury.
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 en-ergising power tools that have the switch on invites acci-dents.
Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a ro-tating 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 jewel-lery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
If devices are provided for the connection of dust ex-traction and collection facilities, ensure these are con-nected and properly used. Use of dust collection can re-duce dust-related 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 accident
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 bind-ing 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 tool
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 ac-cordance 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 per-son using only identical replacement parts. This will en-sure that the safety of the power tool is maintained.

**Safety Warnings for Multi-Cutters

**

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 the machine only for dry sanding. Penetration of water into the machine increases the risk of an electric shock.
Caution, fire hazard! Avoid overheating the object being sanded as well as the sander. Always empty the dust collector before taking breaks. In unfavorable conditions, e. g., when sparks emit from sanding metals, sanding debris in the dust bag, micro filter or paper sack (or in the filter sack or filter of the vacuum cleaner) can self-ignite. Particularly when mixed with remainders of varnish, polyurethane or other chemical materials and when the sanding debris is hot after long periods of working.
Keep hands away from the sawing range. Do not reach under the workpiece. Contact with the saw blade can lead to injuries.
Use suitable detectors to determine if utility lines are hidden in the work area or call the local utility company for assistance. Contact with electric lines can lead to fire and electric shock. Damaging a gas line can lead to explosion. Penetrating a water line causes property damage or may cause an electric shock.
When working with the machine, always hold it firmly with both hands and provide for a secure stance. The power tool is guided more secure with both hands.
Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand.
Wear protective gloves when changing application tools/accessories. Application tools/accessories become hot after prolonged usage.
Do not scrape wetted materials (e.g. wallpaper) or on moist surfaces. Penetration of water into the machine in-creases the risk of an electric shock.
Do not treat the surface to be worked with solvent-containing fluids. Materials being warmed up by the scraping can cause toxic vapours to develop.
Exercise extreme caution when handling the scraper. The accessory is very sharp; danger of injury.
Products sold in GB only: Your product is fitted with an BS 1363/A approved electric plug with internal fuse (ASTA approved to BS 1362). If the plug is not suitable for your socket outlets, it should be cut off and an appropriate plug fitted in its place by an authorized customer service agent. The replacement plug should have the same fuse rating as the original plug. The severed plug must be disposed of to avoid a possible shock hazard and should never be inserted into a mains sock-et elsewhere.

Noise/Vibration Information

BOSCH GOP 30-28 Professional Multi-Cutter 33
The vibration level given in this information sheet has been measured in accordance with a standardized test given in EN 60745 and may be used to compare one tool with another. It may be used for a preliminary assessment of exposure. The declared vibration emission level represents the main ap- plications of the tool. However if the tool is used for different applications, with different accessories or insertion tools or is poorly maintained, the vibration emission may differ. This may significantly increase the
exposure level over the total working period.
An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or when it is running but not actually doing the job. This may significantly reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep the hands warm, organization of work patterns.

Assembly

Changing the Tool

Before any work on the machine itself, pull the mains plug.
Wear protective gloves when changing application tools/accessories. Contact with the application tool/ac-cessory can lead to injuries.

Selecting the Sanding Sheet
Depending on the material to be worked and the required rate of material removal, different sanding sheets are available:
BOSCH GOP 30-28 Professional Multi-Cutter 37

Dust/Chip Extraction

Dust from materials such as lead-containing coatings, some wood types, minerals and metal can be harmful to one’s health. Touching or breathing-in the dust can cause allergic reactions and/or lead to respiratory infections of the user or bystanders.
Certain dust, such as oak or beech dust, is considered carcinogenic, especially in connection with wood-treatment additives (chromate, wood preservative). Materials containing asbestos may only be worked by specialists.
- As far as possible, use a dust extraction system suitable for the material.
- Provide for good ventilation of the working place.
- It is recommended to wear a P2 filter-class respirator. Observe the relevant regulations in your country for the materials to be worked.

Connecting the Dust Extraction

The dust extraction 8 is intended only when working with the sanding plate 9; it is not of use in combination with other application tools.
For sanding, always connect the dust extraction.
To mount the dust extraction 8 (accessory), remove the application tool and the depth stop 15.
Slide the dust extraction 8 all the way over the tool holder 4 onto the collar of the power tool. Turn it to the required position. Press shut the clamping lever 16 to fix the dust extraction.
Plug the tool sleeve 18 of the vacuum hose 19 onto the vacuum connection 17. Connect the vacuum hose 19 to a vacuum cleaner (accessory). You will find an overview of connecting to various vacuum cleaners on the fold-out page.
The vacuum cleaner must be suitable for the material being worked.
When vacuuming dry dust that is especially detrimental to health or carcinogenic, use a special vacuum cleaner.

Operation

Observe correct mains voltage! The voltage of the power source must agree with the voltage specified on the nameplate of the machine.
Power tools marked with 230 V can also be operated with 220 V.
Products sold in AUS and NZ only: Use a residual current de-vice (RCD) with a rated residual current of 30 mA or less.

Starting Operation

Switching On and Off

To start the machine, push the On/Off switch 1 forward so that the “I” is indicated on the switch.
To switch off the machine, push the On/Off switch 1 toward the rear so that the “0” is indicated on the switch.
To save energy, only switch the power tool on when using it.
GOP 40-30: The work light improves visibility in the immediate work area. It is automatically switched on and off with the power tool.
Do not look directly into the work area illumination – your sight can be temporarily degraded!

Preselecting the Orbital Stroke Rate

With the thumbwheel for preselection of the orbital stroke rate 2, you can preselect the required orbital stroke rate, even during operation.
The required stroke rate depends on the material and the working conditions and can be determined through practical testing.

Working Advice

Before any work on the machine itself, pull the mains plug.
Wait until the machine has come to a standstill before placing it down.

Note: Do not cover off the venting slots 3 of the machine while working, as this reduces the working life of the machine.
Operating Principle

The oscillating drive causes the application tool/accessory to oscillate back and forth up to 20000 times per minute. This enables precise work in the tightest of spaces.
Work with low and uniform application pressure, otherwise, the working perfor-mance will decline and the application tool can become blocked.
While working, move the machine back and forth, so that the application tool does not heat up excessively and become blocked.

Sawing

Use only undamaged saw blades that are in perfect condition. Bent or dull saw blades can break, negatively influence the cut, or lead to kickback.
When sawing light building materials, observe the statutory provisions and the recommendations of the material suppliers.
Plunge cuts may only be applied to soft materials, such as wood, gypsum plaster boards, etc.!
Before sawing with HCS saw blades in wood, particle board, building materials, etc., check these for foreign objects such as nails, screws, or similar. If required, remove foreign ob-jects or use BIM saw blades.

Separating
Note : When separating wall tiles take into consideration that the application tools/accessories wear heavily when used for longer periods of time.
Sanding

The removal rate and the sanding pattern are primarily deter-mined by the choice of sanding sheet, the preset oscillation rate and the applied pressure.
Only flawless sanding sheets achieve good sanding capacity and extend the service life of the machine.
Pay attention to apply uniform sanding pressure; this increases the working life of the sanding sheets.
Intensifying the sanding pressure does not lead to an in-crease of the sanding capacity, but to increased wear of the machine and the sanding sheet.
For precise on-the-spot sanding of edges, corners and hard to reach areas, it is also possible to work only with the tip or an edge of the sanding plate.
When selectively sanding on the spot, the sanding sheet can heat up considerably. Reduce the orbital stroke rate and the sanding pressure, and allow the sanding sheet to cool down regularly.
A sanding sheet that has been used for metal should not be used for other materials.
Use only original Bosch sanding accessories.
For sanding, always connect the dust extraction.

Scraping

For scraping, select a high oscillation rate.
Work on a soft surface (e.g. wood) at a flattage, and apply only light pressure. Otherwise the scraper can cut into the surface.

Maintenance and Service

Maintenance and Cleaning

Before any work on the machine itself, pull the mains plug.
For safe and proper working, always keep the machine and ventilation slots clean.
Clean Riff application tools (accessory) regularly with a wire brush.
If the replacement of the supply cord is necessary, this has to be done by Bosch or an authorized Bosch service agent in or-der to avoid a safety hazard.
