Rotating the Machine Head
Before any work on the machine itself, pull the mains
plug.
The machine head can be
rotated with respect to
the machine housing in
90° steps. In this man-
ner, the On/Off switch
can be brought into a
more convenient posi-
tion for special working
situations, e. g., for cut-
ting operations using the
cutting guide with dust
extraction protection
guard 20 or for left-hand-
ed persons.
Completely unscrew the four screws. Rotate the machine
head carefully, without removing it from the housing, to the
new position. Screw in and tighten the four screws again.
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.
– 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.
Prevent dust accumulation at the workplace. Dust can
easily ignite.
Bosch Power Tools
Operation
Starting Operation
-1
[min
]
[m/s]
Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
11000
80
nameplate of the machine. Power tools marked with
11000
80
230 V can also be operated with 220 V.
Hold power tool by insulated gripping surfaces 22 and
auxiliary handle 5 only. The accessory may contact hid-
11000
80
den wiring or its own cord. Accessory contacting a "live"
11000
80
wire may make exposed metal parts of the power tool "live"
and shock the operator.
When operating the machine with power from mobile genera-
11000
45
tors that do not have sufficient reserve capacity or are not
11000
45
equipped with suitable voltage control with starting current
amplification, loss of performance or untypical behavior can
occur upon switching on.
Please observe the suitability of the power generator being
used, particularly with regard to the mains voltage and fre-
quency.
Switching On and Off
To start the machine, first slide the lock-off button 3 to the
rear and then push the On/Off switch 2 and keep it pressed.
To switch off the machine, release the On/Off switch 2.
Check grinding tools before using. The grinding tool
must be mounted properly and be able to move freely.
Carry out a test run for at least one minute with no load.
Do not use damaged, out-of-centre or vibrating grind-
ing tools. Damaged grinding tools can burst and cause in-
juries.
Working Advice
Before any work on the machine itself, pull the mains
plug.
Exercise caution when cutting slots in structural walls;
see Section "Information on Structures".
Clamp the workpiece if it does not remain stationary
due to its own weight.
Do not strain the machine so heavily that it comes to a
standstill.
After heavily straining the power tool, continue to run
it at no-load for several minutes to cool down the acces-
sory.
Do not touch grinding and cutting discs before they
have cooled down. The discs can become very hot while
working.
Do not use the power tool with a cut-off stand.
Rough Grinding
Never use a cutting disc for roughing.
The best roughing results are achieved when setting the ma-
chine at an angle of 30° to 40°. Move the machine back and
forth with moderate pressure. In this manner, the workpiece
will not become too hot, does not discolour and no grooves
are formed.
