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 car-
cinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials con-
taining asbestos may only be worked by specialists.
– 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.
 Prevent dust accumulation at the workplace. Dust can
easily ignite.

– When working with plastics and other materials with a low
melting point, use low speeds.

– When polishing, buffing and cleaning, work with speeds of
up to max. 15000 rpm in order to avoid damaging the
workpiece and application tool.
Working Advice
Detailed work can be carried out best if you hold the power
tool as a pen between thumb and index finger (see figure F).
For heavy work such as cutting or grinding, use the "golf grip
method" (see figure G).
Bosch Power Tools
Move the cutting disc or grinding accessory with light pres-
sure to achieve an optimum work result. Too much pressure
will reduce the performance of the power tool and lead to fast-
er wear of the application tool.

Recommended Cutting Methods
– Panel materials (see figure H)
– Bars (see figure I)
– Pipes (see figure J)
Blockage protection
The built-in blockage protection protects the motor and bat-
tery in case of a blockage. If the application tool becomes
jammed in the workpiece or if too much pressure is exerted on
the workpiece, the motor will stop.
– Determine the cause of the blockage and correct it.
