Operation
Intended Use

The air needle scaler has been designed for removing rust (stuck chunks
of rust are knocked off), for descaling and similar applications. The nee-
dle scaler can only be used to process massive metal parts, because the
high impact rate of the needles may penetrate thinner plates.

The intended use also includes an operation following the operating in-
structions.

Any use beyond these parameters (different media, applying force) or
any changes (reconstruction, no original accessory) can lead to serious
risks and is regarded as use that is contrary to the intended purpose.
Before first Use
Unpack the air needle scaler and check all parts for any damage in transit.
Dispose of packaging materials or store them out of reach of children. There
is risk of suffocation.
Operation
1. Screw the needle guide (2)
and the air needle scaler to-
gether by turning the needle
guide
clockwise on the
thread. Only hand-tight the
needle guide.
The air needle scaler
is equipped with an R ¼“ air inlet (6). For your own
safety it is not recommended to use a permanent connection between
the air needle scaler and the air hose, but use the plug nipple (7) instead.
2. Seal the end of the plug nipple (7) with Teflon tape before you screw it
onto the air connection of the air needle scaler.
The device has to be provided with lubricating oil during operation. Be-
fore each use add oil through the air inlet (6) or use an oil-fog lubricator.
Also read the chapter “Lubrication”.
3. Use a flexible hose to connect the air needle scaler to the compressor.
Set up a pressure of approx. 6.3 bar on the compressor. Check all air
connections for leakages.
