Lubrication
ISO viscosity class according to DIN ISO 3448, VG 5 to 15
Fill the mist lubricator with acid- and resin-free compressed air oil.
The use of a mist lubricator is mandatory:
•
for the models NTK16
,
NTK
25, NTK
40, NTK
55, NTK
85,
NTK
110,
•
when using additional oscillating weights,
•
if NTK is used as an impactor,
•
when using dried compressed air,
•
in aggressive ambient conditions.
A mist lubricator is recommended by
Netter
Vibration
for all NTK vibra-
tors (except NTK L).
