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 significantly
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 acces-
sories, keep the hands warm, organisation of work patterns.

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
– Ring spanner 14
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 12 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
21 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.
Removing the Cutting Disc
– Bring the power tool into the working position. (see “Re-
leasing the Machine (Working Position)”, page 18)
– Swing back the retracting blade guard 4 to the stop.
– Turn hexagon bolt 24 with the provided ring spanner 14
(15 mm) and at the same time press the spindle lock 5 un-
til it engages.
– Hold the spindle lock pressed and unscrew the hexagon
bolt 24.
– Remove the washer 23 and the clamping flange 22.
– Remove the cutting disc 6.
