Mounting the Protective Devices
 Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport
and storage, remove the battery from the power tool.
There is danger of injury when unintentionally actuating
the On/Off switch.
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 10 on
the spindle collar. Adjust the posi-
tion of the protection guard 10 to
the requirements of the operation.
Lock the protection guard 10 tight-
ening the locking screw 9 with a hex
key 4.
 Adjust the protection guard 10 in such a manner that
sparking is prevented in the direction of the operator.
Note: The encoding keys on the protection guard 10 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 16.
 Provide for sufficient dust extraction when cutting
stone.
The protection guard for cutting 16 is mounted in the same
manner as the protection guard for grinding 10.
Cutting Guide with Dust Extraction Protection Guard
The cutting guide with dust extraction protection guard 26 is
mounted in the same manner as the protection guard for
grinding 10.
Auxiliary Handle
 Operate your machine only with the auxiliary handle 7.
Screw the auxiliary handle 7 on the right or left of the machine
head depending on the working method.
Hand Guard
 For operations with the rubber sanding plate 19 or with
the cup brush/wheel brush/flap disc, always mount the
hand guard 18.
The hand guard 18 is fastened with the auxiliary handle 7.
Bosch Power Tools
Mounting the Grinding Tools
 Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport
and storage, remove the battery from the power tool.
There is danger of injury when unintentionally actuating
the On/Off switch.
 Do not touch grinding and cutting discs before they
have cooled down. The discs can become very hot while
working.
Clean the grinder spindle 8 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
13 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.
A plastic part (O-ring) is fitted around
the centring collar of mounting flange
11. If the O-ring is missing or dam-
aged, the mounting flange 11 must be
replaced before resuming operation.
Flap Disc
 For operations with the flap disc, always mount the
hand guard 18.
Rubber Sanding Plate
 For operations with the rubber sanding plate 19, al-
ways mount the hand guard 18.
See graphics page for the mounting sequence.
Screw on the round nut 21 and tighten with the two-pin span-
ner.
