Noise/Vibration Information
Noise emission values determined according to
EN 62841‑2‑8.
Typically, the A-weighted noise level of the power tool is:
Sound pressure level 83 dB(A); sound power level
94 dB(A). Uncertainty K = 3 dB.

The vibration level and noise emission value given in these
instructions have been measured in accordance with a
standardised measuring procedure and may be used to com-
pare power tools. They may also be used for a preliminary
estimation of vibration and noise emissions.
The stated vibration level and noise emission value repres-
ent the main applications of the power tool. However, if the
power tool is used for other applications, with different ap-
plication tools or is poorly maintained, the vibration level
and noise emission value may differ. This may significantly
increase the vibration and noise emissions over the total
working period.
To estimate vibration and noise emissions accurately, the
times when the tool is switched off or when it is running but
not actually being used should also be taken into account.
This may significantly reduce vibration and noise emissions
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 their hands warm,
and organising workflows correctly.
Assembly
Auxiliary handle
Screw the auxiliary handle (3) into the thread (6) on the left-
GNA 3,5
or right-hand side of the housing.

Adjusting the hold-down device
Adjusting the hold-down device (12) to the thickness of the
sheet being cut eliminates vibrations.
Hold the power tool so that the die (14) touches the under-
side of the sheet to be cut. Loosen the screws (13) on the
Products that are only sold in AUS and NZ: Use a resid-
ual current device (RCD) with a nominal residual current
of 30 mA or less.
Pay attention to the mains voltage. The voltage of the
power source must match the voltage specified on the
rating plate of the power tool. Power tools marked
with 230 V can also be operated with 220 V.
