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.

controller on motor

Speed controller

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.
