Operation
The Needle Scaler is designed for rust and paint removal, weld dressing
and scaling, deslagging, cleaning concrete, etc. It is powerful and has a
very high scaling efficiency. The remarkably low vibration level makes it
possible to work with higher precision than with other tools and the noise
level is low compared to other needle scalers. With these ergonomic
features you can work for longer periods without fatigue.
As the GNV-19 doesn’t work exactly in the same way as conventional
scalers, you need to get acquainted with the tool to be able to fully take
advantage of the advanced features.
The scaling efficiency depends somewhat on the force you apply on the
tool. For efficient material removal you will find that an intermediate force
works the best. Don’t be fooled by the fact that you don’t feel a lot of
vibrations. The tool is very strong and works fast. Look at the result on
the surface you are working on!
The discharge of the compressed air is through the front of the tool.
Some air circulates in and out of the tool through an opening between
the rear (21) and the housing cover (23). This circulation is directed
towards one side and downwards but the opening in the housing cover
can be rotated to direct the circulation flow as desired.
This tool is a low vibration tool. If you can feel that the vibration level has
increased, stop using the tool! Increased vibrations indicate that
something is wrong and continued operation might damage or destroy
internal parts. The reason for more vibrations can be a damaged
housing, a broken spring or other part. It can also depend on that the tool
has been pulled apart and not been assembled properly.
For applications that produce a lot of dust it may be advantageous to
connect the tool to an industrial vacuum cleaner. This can be done via a
vacuum attachment that fits around the front part of the housing. See
page 6 for the part number.
The tool can also be fitted with a chisel adapter for occasional chisel
work. See page 6 for the part number.
