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.
Please observe the article number on the type plate of your machine.
The trade names of the individual machines may vary.
Noise/Vibration Information
Measured sound values determined according to EN 60745.
Typically the A-weighted noise levels of the product are:
Sound pressure level 92 dB(A); Sound power level
103 dB(A). Uncertainty K =3 dB.

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
1 609 929 Y20 | (13.7.11)
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
GKT 55 GCE
accessories, keep the hands warm, organisation of work pat-
Professional
terns.

Before any work on the machine itself, pull the mains
plug.
When mounting the saw blade, wear protective gloves.
Danger of injury when touching the saw blade.
Only use saw blades that correspond with the charac-
teristic data given in the operating instructions.
Do not under any circumstances use grinding discs as
the cutting tool.
Selecting a Saw Blade
An overview of recommended saw blades can be found at the
end of this manual.

Cutting Depth".
For changing the cutting tool, it is best to place the machine
on the face side of the motor housing.
– Pivot lever 3 toward the front.
– Push lock-off button 2 toward the front and press the saw
toward base plate 7 until it engages in the position for
changing the saw blade.
– Press the spindle lock button 25 and keep it pressed.
