Noise/Vibration Information
Sound emission values determined according to
EN 60745-2-3.
Typically the A-weighted noise levels of the product are:
Sound pressure level 91 dB(A); Sound power level
102 dB(A). Uncertainty K =3 dB.
Wear hearing protection!
Vibration total values a

The vibration level given in this information sheet has been
measured in accordance with a standardised test given in
EN 60745 and may be used to compare one tool with anoth-
er. It may be used for a preliminary assessment of exposure.
The declared vibration emission level represents the main ap-
plications of the tool. However if the tool is used for different
applications, with different accessories or insertion tools or is
poorly maintained, the vibration emission may differ. This
may significantly increase the exposure level over the total
working period.
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 sig-
nificantly 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
accessories, keep the hands warm, organisation of work pat-
terns.
Assembly
Mounting the Protective Devices
Before any work on the machine itself, pull the mains
plug.
Note: After breakage of the grinding disc during operation or
damage to the holding fixtures on the protection guard/power
tool, the machine must promptly be sent to an after-sales ser-
vice agent for maintenance. For addresses, see section "Af-
ter-sales Service and Application Service".
Protection Guard for Grinding
Place the protection guard 7 on the
spindle collar. Adapt the position of
the protection guard 7 to the re-
quirements of the work step. Lock
protection guard 7 by tightening
locking screw 20 with combination
spanner 4.
1 609 92A 3YF | (27.3.18)
Adjust the protection guard 7 in such a manner that
sparking is prevented in the direction of the operator.
Note: The encoding keys on the protection guard 7 ensure
that only a protection guard that fits the machine type can be
mounted.
Protection Guard for Cutting
For cutting with bonded abrasives, always use the pro-
tection guard for cutting 12.
Provide for sufficient dust extraction when cutting

,
stone.

.
The protection guard for cutting 12 is mounted in the same
manner as the protection guard for grinding 7.
Auxiliary Handle
Operate your machine only with the auxiliary handle 5.
Screw the auxiliary handle 5 on the right or left of the machine
head depending on the working method.
Hand Guard
For operations with the rubber sanding plate 15 or with
the cup brush/wheel brush/flap disc, always mount the
hand guard 14.
The hand guard 14 is fastened with the auxiliary handle 5.
Mounting the Grinding Tools
Before any work on the machine itself, pull the mains
plug.
Do not touch grinding and cutting discs before they
have cooled down. The discs can become very hot while
working.
Clean the grinder spindle 6 and all parts to be mounted.
For clamping and loosening the grinding tools, lock the grind-
er spindle with the spindle lock button 1.
Actuate the spindle lock button only when the grinder
spindle is at a standstill. Otherwise, the machine may be-
come damaged.
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 di-
rection-of-rotation arrow on the diamond cutting disc and the
direction of rotation of the machine (see direction-of-rotation
arrow on the machine head) agree.
See graphics page for the mounting sequence.
To fasten the grinding/cutting disc, screw on the clamping nut
10 and tighten it with the combination spanner 4.
After mounting the grinding tool and before switching
on, check that the grinding tool is correctly mounted
and that it can turn freely. Make sure that the grinding
tool does not graze against the protection guard or oth-
er parts.
