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 sig-
nificantly 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, organisation of work pat-
terns.
Assembly
Mounting the Protective Devices
 Before any work on the machine itself, pull the mains
plug.
Note: After breakage of the grinding disc during operation or
damage to the holding fixtures on the protection guard/power
tool, the machine must promptly be sent to an after-sales ser-
vice agent for maintenance. For addresses, see section "Af-
ter-sales Service and Application Service".
Protection Guard for Grinding
Place the protection guard 12 on-
to the spindle collar as shown in
the illustration. The triangle marks
on the protection guard must cor-
respond with the respective
marks on the gear case.
Press the protection guard 12 on-
to the spindle collar until the
shoulder of the protection guard
is seated against the flange of the
machine, and turn the protection
guard until it can clearly be heard
to engage.
Adjust the position of the protec-
tion guard 12 to the requirements
of the work process. For this, press the release lever 1 up-
ward and turn the protection guard 12 to the required posi-
tion.
 Adjust the protection guard 12 in such a manner that
sparking is prevented in the direction of the operator.
 The protection guard 12 may be turned only upon actu-
ation of the release lever 1! Otherwise the power tool
may not continue to be used under any circumstances
and must be taken to an after-sales service agent.
Note: The encoding keys on the protection guard 12 ensure
that only a protection guard that fits the machine type can be
mounted.
Protection Guard for Cutting
 For cutting with bonded abrasives, always use the pro-
tection guard for cutting 14.
 Provide for sufficient dust extraction when cutting
stone.
The protection guard for cutting 14 is mounted in the same
manner as the protection guard for grinding 12.
Bosch Power Tools
Cutting Guide with Dust Extraction Protection Guard
The cutting guide with dust extraction protection guard 21 is
mounted in the same manner as the protection guard for
grinding 12.
Extraction Hood for Sanding
The extraction hood 7 can be used for low-dust sanding of
paint, varnish and plastics in conjunction with the carbide
grinding head 9 or the rubber sanding plate 17 with a sanding
sheet 18. The extraction hood 7 is not suitable for working
metals.
A suitable Bosch vacuum cleaner can be connected to the ex-
traction hood 7.
The extraction hood 7 is mounted in the same manner as the
protection guard 12. The brush collar is exchangeable.
Auxiliary Handle
 Operate your machine only with the auxiliary handle 5.
Screw the auxiliary handle 5 on the right or left of the machine
head depending on the working method.
Hand Guard
 For operations with the rubber sanding plate 17 or with
the cup brush/wheel brush/flap disc, always mount the
hand guard 16.
The hand guard 16 is fastened with the auxiliary handle 5.
Mounting the Grinding Tools
 Before any work on the machine itself, pull the mains
plug.
 Do not touch grinding and cutting discs before they
have cooled down. The discs can become very hot while
working.
Clean the grinder spindle 6 and all parts to be mounted.
For clamping and loosening the grinding tools, lock the grind-
er spindle with the spindle lock button 2.
 Actuate the spindle lock button only when the grinder
spindle is at a standstill. Otherwise, the machine may be-
come damaged.
Grinding/Cutting Disc
Pay attention to the dimensions of the grinding tools. The
mounting hole diameter must fit the mounting flange without
play. Do not use reducers or adapters.
When using diamond cutting discs, pay attention that the di-
rection-of-rotation arrow on the diamond cutting disc and the
direction of rotation of the machine (see direction-of-rotation
arrow on the machine head) agree.
See graphics page for the mounting sequence.
To fasten the grinding/cutting disc, screw on the clamping nut
10 and tighten with the two-pin spanner; see Section "Quick-
clamping Nut ".
 After mounting the grinding tool and before switching
on, check that the grinding tool is correctly mounted
and that it can turn freely. Make sure that the grinding
tool does not graze against the protection guard or oth-
er parts.
