Bosch GRO 10,8 V-LI Original Instructions Manual page 19

Certain dusts, such as oak or beech dust, are considered
as carcinogenic, especially in connection with wood-treat-
ment additives (chromate, wood preservative). Materials
containing 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. Dusts can
easily ignite.

– When working with plastics and other materials with a low
melting point, use low speeds.
– Perform cutting work in wood, iron or steel at high 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).
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.
 Ensure that grinding tools and cutting discs are pro-
tected against impact when stored.

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.

Maintenance and Cleaning
 Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport

 For safe and proper working, always keep the machine
