The vibration level given in these instructions has been
measured in accordance with a standardised measuring pro-
cedure and may be used to compare power tools. It can also
be used for a preliminary estimation of exposure to vibra-
tion.
The stated vibration level applies to the main applications of
the power tool. However, if the power tool is used for differ-
ent applications, with different application tools or poorly
maintained, the vibration level may differ. This can signific-
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 protection guard
(6) on the spindle collar. Ad-
just the position of the pro-
tection guard (6) to the re-
quirements of the operation.
Lock the protection guard (6)
by tightening the locking
screw (5) using a cross-head
screwdriver.
Adjust the protective guard (6) such that sparking in
u
the direction of the operator is prevented.
1 609 92A 36V | (01.06.2021)
Note: The encoding keys on the protection guard (6) ensure
that only a protection guard that fits the machine type can be
mounted.
Protective guard for cutting
Always use the protective guard for cutting (11) when
u
cutting with bonded abrasives.
Provide sufficient dust extraction when cutting stone.
u
The protective guard for cutting (11) 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 (18) 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 (3).
Screw the side handle (3) 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 (13) when working with the
u
rubber sanding plate (14) or with the cup brush/disc
brush/flap disc.
Attach the hand guard (13) to the side handle (3).
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 (4) 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 grinding tools. The
mounting hole diameter must fit the mounting flange without
play. Do not use reducers or adapters.
When using diamond cutting discs, pay attention that the
direction-of-rotation arrow on the diamond cutting disc and
the direction of rotation of the machine (see direction-of-ro-
tation arrow on the machine head) agree.
See graphics page for the mounting sequence.
The low-vibration auxiliary
handle reduces vibration,
enabling the tool to be used
safely and more comfort-
