Depending on the intended use, NTK can be screwed on either with the cover/housing or
with the piston. Mount the NTK on the mounting thread (cover or piston) with a suitable
fastening screw and safety washer.
If necessary, additionally use a medium-strength liquid safety agent to secure the screw
connections. Observe the recommended values for screw sizes and tightening torques.

Vibration recommends NBS fastening kits for secure and permanent fastening.
3.
Fasten the compressed air supply securely. Observe the recommended cross-sections
for valves and hoses. For the air supply, use screw connections with integrated flat seal
or liquid sealant.
Notice: Screw-in threads that are too long can lead to machine damage.
The air resistance increases with the hose length. The specified nominal diameters apply
to hose lengths up to 3 m. Longer supply lines require larger cross-sections.
Discharge the escaping air through a hose if necessary (e. g. in dusty environments). To
achieve full performance, the exhaust hose must have a larger nominal size than the
supply hose.
4.
Mount the silencer/silencers.

Start-up and operation
Observe the safety instructions in chap. Safety, starting on page 3.
Observe the permissible operating conditions in chap. Technical data, page 4.
Starting pressure at low temperatures or after prolonged storage
At ambient temperatures 10 °C or after prolonged storage higher starting pressures
(≥ 2 bar) may be required. Start the NTK with a higher pressure of approx. 5 bar and then re-
duce to 2 bar.
Setting the frequency
The frequency of the NTK is set with the pressure regulator of the maintenance unit.
The frequency is reduced by lowering the air pressure before the NTK. The centrifugal force
is hereby also reduced. At the same time the amplitude remains almost constant.
Adjustment of amplitude
If required, install a throttle valve in the exhaust air line in order to adjust the amplitude of the
NTK by throttling the exhaust air. By throttling the exhaust air, the centrifugal force is reduced.
The frequency hereby remains almost constant.
Important: Reduced cross-sections already throttle (observe the nominal diameter).
Reduce the amplitude only up to approx. 50 %. This can cause start-up problems if below.
Setting mist lubricator
Set the mist lubricator to the recommended number of drops while the NTK is running.
Notice: The NTK is ready for operation only after adjustment and correct functioning of the
mist lubricator.
