Assembly
► Avoid unintentional starting of the machine. During
assembly 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 accessories 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 13
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 9 serve for this
purpose.
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–B4)
► Before any work on the machine itself, pull the mains plug.
► Actuate the spindle lock 4 only when the tool spindle
24 is stopped. Otherwise, the machine can become
damaged.
► Do not touch the cutting disc after working before it
has cooled. The cutting disc becomes very hot while working.
Use only cutting discs that have an equal or higher maximal
allowable 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
according 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
"Releasing the Machine)", page 22.
– Pull lever 19 upward and slide it alongside the guide groove.
This pivots the retracting blade guard 5 upward to the stop,
where it is held in the open position.
– Loosen wing bolt 21 and swing the cover lid 20 toward
the rear.
