Fitting Protective Equipment
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Note: If the grinding disc breaks during operation or the
holding fixtures on the protective guard/power tool become
damaged, the power tool must be sent to the after-sales ser-
vice immediately; see the "After-Sales Service and Applica-
tion Service" section for addresses.
Protective Guard for Grinding
Open the clamping lever (8). Place the protective guard (6)
with the coding cam (7) engaging into the coding groove on
the spindle collar until the shoulder of the protective guard is
seated against the flange of the power tool, and turn the pro-
tective guard (6) to the required position. Close the clamp-
ing lever (8).
Adjust the protective guard (6) such that sparking in
u
the direction of the operator is prevented.
The tensioning force of the clamp from the protective
guard (6) can be changed by loosening or tightening the ad-
justment screw (9). Ensure that protective guard (6) is fitted
securely and check it regularly.
Note: The coding cams on the protective guard (6) ensure
that only a protective guard that is suitable for the power
tool can be fitted.
Protective guard for cutting
Always use the protective guard for cutting (15) when
u
cutting bonded abrasives.
Provide sufficient dust extraction when cutting stone.
u
The protective guard for cutting (15) is fitted in the same
way as the protective guard for grinding (6).
Extraction guard for cutting with a guide block
The extraction guard for cutting with a guide block (20) is fit-
ted in the same way as the protective guard for grinding (6).
Side handle
Do not operate your power tool without the side
u
handle (4).
Do not continue to use the power tool if the auxiliary
u
handle is damaged. Do not make any alterations to the
auxiliary handle.
Screw the side handle (4) on the left or right of the machine
head depending on how your are working.
Vibration Damping
The integrated vibration
damping function reduces
the generated vibration.
Do not continue to use the power tool if the damping
u
element is damaged.

Hand guard
Always fit the hand guard (21) when working with the
u
rubber sanding plate (23) or with the cup brush/disc
brush/flap disc.
Attach the hand guard (21) to the side handle (4).
Fitting the abrasive tools
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Do not touch grinding and cutting discs until they have
u
cooled down. The discs can become very hot while work-
ing.
Clean the grinding spindle (18) and all the parts to be fitted.
Lock the grinding spindle with the spindle lock button (1)
before clamping and releasing the abrasive tools.
Do not press the spindle lock button while the grind-
u
ing spindle is moving. The power tool may become dam-
aged if you do this.
Quick-clamping nut
To change the abrasive tool easily without having to use any
additional tools, you can use the quick-clamping nut (14) in-
stead of the clamping nut (13).
The quick-clamping nut (14) may be used only for
u
grinding or cutting discs.
Only use quick-clamping nuts (14) that are in good work-
ing order and not damaged.
When screwing on, make sure that the printed side of the
quick-clamping nut (14) is not facing the grinding disc;
the arrow must be pointing towards the index mark (27).
(27)
Press the spindle lock but-
ton (1) to lock the grinding
spindle. To tighten the
quick-clamping nut, turn
the grinding disc firmly
clockwise.
If the quick-clamping nut
has been attached correctly
and is not damaged, you
can loosen it by hand by
turning the knurled ring an-
ticlockwise. If the quick-
clamping nut is stuck, do
not attempt to loosen it
with pliers – always use
the two-pin spanner. Posi-
tion the two‑pin spanner as
shown in the figure.
