Protection class
The values given are valid for a nominal voltage [U] of 230 V. For differ-
ent voltages and models for specific countries, these values can vary.
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 93 dB(A); Sound power level
104 dB(A). Uncertainty K =3 dB.
Wear hearing protection!
Vibration total values a (triax vector sum) and uncertainty K
h
determined according to EN 60745-2-3:
2
Surface grinding: a =7.5 m/s , K=1.5 m/s
h
2
Disk sanding: a =7.5 m/s , K=1.5 m/s
h
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.

damage to the holding fixtures on the protection guard/power
tool, the machine must promptly be sent to an after-sales ser-

Protection Guard for Grinding
mm 22
Place the protection guard 6 on the spindle collar. Adjust the

position of the protection guard 6 to the requirements of the
operation. Lock the protection guard 6 by tightening the lock-
ing screw 7 using the combination spanner 4.
 Adjust the protection guard 6 in such a manner that

sparking is prevented in the direction of the operator.
kg 1.9
Note: The encoding keys on the protection guard 6 ensure
/II
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 13.
 Provide for sufficient dust extraction when cutting
stone.
The protection guard for cutting 13 is mounted in the same
manner as the protection guard for grinding 6.
Auxiliary Handle
 Operate your machine only with the auxiliary handle 3.

head depending on the working method.
Hand Guard
 For operations with the rubber sanding plate 16 or with
the cup brush/wheel brush/flap disc, always mount the
hand guard 15.
The hand guard 15 is fastened with the auxiliary handle 3.
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 5 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.
