and other regulations which are valid in individual countries
should be adhered to.
Danger
Lethal danger due to electric shock!
¾Remove the plug from the plug socket before undertaking any
maintenance work on the machine.
¾Check the plug, the cable and the machine for damage each
time before the appliance is used.
¾Keep the machine dry and do not operate in damp rooms.
¾When using the electric tool outside, connect the fault current
(FI) protective switch with a maximum breaking current of
30 mA.
Warning
Danger of injury possible due to improper handling!
¾When working with the machine, wear safety glasses, hearing
protection, protective gloves and work shoes.
¾Do not plug in the plug unless the machine has been
switched off. Pull out the mains plug after use.

2.1 Correct use
Warning
Risk of injury!
¾For processing and materials, only use machines which are
named in "Correct use".
The TRUMPF Nibbler TruTool N 350 is an electric hand tool used
for the following applications:
•Slitting plate-shaped workpieces made of a punchable material
such as steel, aluminium, non-ferrous heavy metals, and
plastic.
•Nibbling straight or curved exterior and interior cutouts.
•Nibbling from scribed lines or templates.
Note
The nibbling process produces cutting edges free of deformations.
Note
Because of the hollow round punch, the nibbler can be rotated at
any position such that processing can continue mm any direction.

Reducing the stroke rate: rotate setting wheel for the speed
controller counter-clockwise.
A reduced number of strokes improves the quality of the work
•for precise machining along scribed lines.
•for machining radiuses.
•for machining steel with a tensile strength > 400 N/mm²
(improved service life).

4. Operation
Caution
Damage to property possible due to too-high network
voltage!
Damage to the motor.
¾Check the power supply. The power supply must correspond
to the information on the machine type plate.
Warning
Danger of injury possible due to improper handling!
¾When working with the machine, always ensure that it has a
secure base.
¾Never touch the tool while the machine is running.
¾Always guide the machine away from the body while working.
¾Do not work holding the machine above your head.
The appliance may switch off prematurely when affected by
electromagnetic disruptions. The appliance will resume operation
once the faults have been cleared.
If the motor temperature is too high, the motor will switch off. The
red indicator light (LED) with the motor lights up.
¾Allow the machine to run in idle until it has cooled down.
The machine can be operated again normally after it has cooled
down.
