The vibration emission 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
another. It may be used for a preliminary assessment of expo-
sure.
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 poorly maintained,
the vibration emission may differ. This may significantly in-
crease 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 pe-
riod.
Identify additional safety measures to protect the operator
from the effects of vibration such as: maintain the tool and the
accessories, keep hands warm, organise work patterns.

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
service agent for maintenance (for addresses, see section
„After-sales Service and Customer Assistance".
Protection Guard for Grinding
Release the clamping lever 8. Place the protection guard 6
with the encoding key 7 engaging into the groove on the spin-
dle collar until the shoulder of the protection guard is seated
against the flange of the power tool, and turn the protection
guard 6 to the requested position. Lock the clamping lever 8.
Adjust the protection guard 6 in such a manner that
sparking is prevented in the direction of the operator.
The tightening tension of the clamp from the protection guard
6 can be changed by loosening or tightening the adjustment
screw 9. Ensure that the protection guard 6 is tightly seated
and check regularly.
Note: The encoding keys on the protection guard 6 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 15.
Provide for sufficient dust extraction when cutting
stone.
The protection guard for cutting 15 is mounted in the same
manner as the protection guard for grinding 6.
Cutting Guide with Dust Extraction Protection Guard
The cutting guide with dust extraction protection guard 23 is
mounted in the same manner as the protection guard for
grinding 6.
Auxiliary Handle
Operate your machine only with the auxiliary handle 4.
Screw the auxiliary handle 4 on the right or left of the machine
head depending on the working method.
Vibration Damper (GWS 26-180 JBV/
GWS 26-230 BV/GWS 26-230 JBV)
The integrated vibration damper reduces occurring vibra-
tions.
