4 Design and function
Start spring
(depending on
the type)
Start connec-
tion (depending
on the type)
There are two versions of the NTS.
Version 1 with aluminium housing and start spring (8) (exception: NTS 21/04).
Version 2 with steel housing and start connection (7).
NTS version 2 units can not start when installed horizontally due to the unfavourable position
of the piston. Therefore, these vibrators have a start connection (7) in the base plate (6), so
that the piston (1) can be pressed by a short pressure surge into the starting position. For this
purpose, an additional pneumatic control is required.
Observe the safety instructions in Ch. Safety, from page 3 on.
Special conditions of transport are not required.
Storage in a dry and clean environment, protected from UV-exposures,
weather and ozone. Storage temperature: -20 °C to 60 °C.
Preserve all NTS apart from the NTS L before storage:
Add anti-corrosion oil to the air inlet. Actuate the NTS briefly when mount-
ed. Close all openings afterwards.
