antly increase the exposure to vibration over the total work-
ing period.
To estimate the exposure to vibration accurately, the times
when the tool is switched off or when it is running but not ac-
tually being used should also be taken into account. This can
significantly reduce the exposure to vibration over the total
working period.
Implement additional safety measures to protect the oper-
ator from the effects of vibration, such as servicing the
power tool and application tools, keeping the hands warm,
and organising workflows correctly.
Fitting
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
Place the protective guard
(7) on the spindle collar. Ad-
just the position of the pro-
tective guard (7) to meet the
requirements of the opera-
tion. Lock the protective
guard (7) by tightening the
locking screw (6) using the
hex key (3).
Adjust the protective guard (7) such that sparking in
u
the direction of the operator is prevented.
Note: The coding cams on the protective guard (7) 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 (8) when
u
cutting bonded abrasives.
Provide sufficient dust extraction when cutting stone.
u
The protective guard for cutting (8) is fitted in the same way
as the protective guard for grinding (7).
Extraction guard for cutting with a guide block
The extraction guard for cutting with a guide block (22) is fit-
ted in the same way as the protective guard for grinding (7).

Side handle
Do not operate your power tool without the side
u
handle (5).
Screw the side handle (5) on the left or right of the machine
head depending on how your are working.
Low-vibration auxiliary handle
ably.
Do not make any alterations of any kind to the auxili-
u
ary handle.
Do not continue to use a damaged auxiliary handle.
Hand guard
Always fit the hand guard (17) when working with the
u
rubber sanding pad (18) or with the cup brush/disc
brush/flap disc.
Attach the hand guard (17) to the side handle (5).
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 (16) 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.
Grinding/cutting disc
Pay attention to the dimensions of the abrasive tools. The
diameter of the hole must match that of the hub flange. Do
not use an adapter or reducer.
When using diamond cutting discs, make sure that the arrow
indicating the direction of rotation on the diamond cutting
disc matches the direction of rotation of the power tool (see
the direction of rotation arrow on the machine head).
See the graphics page for fitting instructions.
To fasten the grinding/cutting disc, screw on the clamping
nut (12) and tighten with the two-pin spanner; see the
"Quick-clamping nut" section.
After fitting the abrasive tool, check that the abrasive
u
tool is fitted correctly and can turn freely before
switching on the power tool. Make sure that the abras-
ive tool does not brush against the protective guard or
other parts.
A plastic part (O-ring) is fitted around the cent-
ring collar in the hub flange (9). If the O-ring
is missing or damaged, the hub flange (9)
must be replaced before operation can re-
sume.
The low-vibration auxiliary
handle reduces vibration,
enabling the tool to be used
safely and more comfort-
