Assembly
Avoid unintentional starting of the machine. During as-
sembly and for all work on the machine, the power plug
must not be connected to the mains supply.
Delivery Scope
Carefully remove all parts included in the delivery from their
packaging.
Remove all packaging material from the machine and the ac-
cessories provided.
Before starting the operation of the machine for the first time,
check if all parts listed below have been supplied:
– Cut-off grinder with mounted cutting disc
– Hex key 12
Note: Check the power tool for possible damage.
Before further use of the machine, check that all protective
devices are fully functional. Any lightly damaged parts must
be carefully checked to ensure flawless operation of the tool.
All parts must be properly mounted and all conditions fulfilled
that ensure faultless operation.
Damaged protective devices and parts must be immediately
replaced by an authorised service centre.
Stationary or Flexible Mounting
To ensure safe handling, the machine must be mounted
on a level and stable surface (e. g., workbench) prior to
using.
Mounting to a Working Surface (see figure A)
– Fasten the power tool with suitable screw fasteners to the
working surface. The mounting holes 11 serve for this pur-
pose.
Flexible Mounting (not recommended!)
In the exceptional case that it should not be possible to firmly
bench-mount the power tool, you can provisionally place the
legs of base plate 13 on a suitable surface (e. g. a workbench,
level floor, etc.) without bolting the machine down.
Changing the Tool (see figures B1–B2)
Before any work on the machine itself, pull the mains
plug.
Actuate the spindle lock 5 only when the tool spindle
20 is stopped. Otherwise, the machine can become dam-
aged.
Do not touch the cutting disc after working before it
has cooled. The cutting disc becomes very hot while work-
ing.
Use only cutting discs that have an equal or higher maximal al-
lowable speed than the no-load speed of your power tool.
Use only cutting discs that correspond to the characteristic
data given in these operating instructions and are checked ac-
cording to EN 12413 and marked appropriately.
Place unused cutting discs in an enclosed container or in the
original packaging. Store cutting discs lying flat.
Bosch Power Tools
Removing the Cutting Disc
– Bring the power tool into the working position. (see "Re-
leasing the Machine (Working Position)", page 17)
– Swing back the retracting blade guard 4 to the stop.
– Turn the hexagon bolt 23 using the hex key provided 12
and at the same time press the spindle lock 5 until it engag-
es.
– Hold the spindle lock pressed and unscrew the hexagon
bolt 23.
– Remove the washer 22 and the clamping flange 21.
– Remove the cutting disc 6.
Installing the Cutting Disc
If required, clean all parts to be mounted prior to assembly.
– Mount the new cutting disc onto the tool spindle 20 in such
a manner that its label faces away from the tool arm.
– Mount the clamping flange 21, the washer 22 and the hex-
agon bolt 23.
Press the spindle lock 5 until it engages and retighten the
hexagon bolt 23 turning in clockwise direction. (Tightening
torque approx. 18–20 Nm)
– Slowly guide the retracting blade guard 4 down until the
cutting disc is covered off.
– Make sure that the retracting blade guard 4 operates prop-
erly.
After mounting the cutting disc and before switching on,
check whether the cutting disc is properly mounted and if it
can rotate freely.
– Make sure that the cutting disc does not graze against the
retracting blade guard 4, the blade guard 18 or against
other parts.
– Run the machine for approx. 30 seconds.
Should significant vibrations occur, switch off the machine
immediately; remove and install the cutting disc again.
Operation
Before any work on the machine itself, pull the mains
plug.
Transport Safety (see figure C)
The transport safety-lock 15 enables easier handling of the
machine when transporting to various working locations.
Releasing the Machine (Working Position)
– Push the tool arm by the handle 3 down a little in order to
relieve the transport safety-lock 15.
– Pull the transport safety-lock 15 completely outward.
– Guide the tool arm slowly upward.
Note: When working, pay attention that the transport safety-
lock is not pushed inwards. Otherwise, the tool arm cannot be
lowered to the requested depth.
Securing the Machine (Transport Position)
– Guide the tool arm downward until the transport safety-
lock 15 can be pushed completely inward.
For additional information on transport, see page 19.
