Fitting Protective Equipment

Note: If the grinding disc breaks during operation or the holding fixtures on the protective guard/power tool become damaged, the power tool must be sent to the after-sales service immediately; see the "After-Sales Service and Application Service" section for addresses.

Place the protective guard (10) onto the holder on the power tool until the coding cams of the protective guard are aligned with the holder. When doing so, press and hold the unlocking lever (1).
Press the protective guard (10) onto the spindle collar until the shoulder of the protective guard is sitting on the flange of the power tool and rotate the protective guard until it audibly clicks into place.
Adjust the position of the protective guard (10) to meet the requirements of the operation. To do this, push the unlocking lever (1) upward and rotate the protective guard (10) into the required position.

  • Always position the protective guard (10) such that the two cams on the unlocking lever  (1) engage in the corresponding openings on the protective guard  (10).
  • Adjust the protective guard (10) such that sparking in the direction of the operator is prevented.
  • The protective guard (10) must only be able to be rotated in the direction of the accessory while the unlocking lever (1) is actuated. Otherwise, the power tool must not be used any more under any circumstances and must be sent to the after-sales service.

Note: The coding cams on the protective guard (10) ensure that only a protective guard that is suitable for the power tool can be fitted.

For low-dust grinding of paints, lacquers and plastics in conjunction with carbide grinding heads (13), you can use the extraction guard (9). The extraction guard (9) is not suitable for machining metal.

A suitable Bosch dust extractor can be connected to the extraction guard (9). To do so, insert the vacuum hose with dust extraction adapter into the provided receiving connection of the extraction guard.

  • Always use the protective guard for cutting (11) when cutting with bonded abrasives.
  • Provide sufficient dust extraction when cutting stone.

The protective guard for cutting (11) is fitted in the same way as the protective guard for grinding (10).

The extraction guard for cutting with a cutting guide (31) is fitted in the same way as the protective guard for grinding.

By securing the auxiliary handle (8)/(7) with the clip through the extraction guard on the gearbox housing, the power tool is firmly attached to the extraction guard. A suitable Bosch dust extractor can be connected to the extraction guard with a cutting guide (31). To do so, insert the vacuum hose with dust extraction adapter into the provided receiving connection of the extraction guard.

Note: The friction generated by the dust in the vacuum hose and accessory during extraction causes an electrostatic charge that the user may experience as static discharge (depending on environmental factors and their physiological state). Bosch generally recommends using an anti-static vacuum hose (accessory) to vacuum up fine dust and dry materials.

  • Always fit the hand guard (23) when working with the rubber sanding pad (24) or with the cup brush/conical brush/diamond annular cutter.

Attach the hand guard (23) to the auxiliary handle (8)/(7).

Screw the auxiliary handle (8)/(7) on the right or left of the machine head depending on the working method.

  • Do not operate your power tool without the auxiliary handle (8)/(7).
  • Do not continue to use the power tool if the auxiliary handle (8)/(7) is damaged. Do not make any alterations to the auxiliary handle (8)/(7).

The low-vibration auxiliary handle (7) reduces vibration, enabling the tool to be used safely and more comfortably.
