The bearings must be greased at the 2 greasing
points (Fig. 4/L) with 6 g per point, after the follow-
ing recommended operating hours or at the latest
one year operation:
50 Hz: V-VTA 60 - 100
➝ 10.000 h and V-VTA 140 ➝
6.000 h
60 Hz: V-VTA 60 / 80
➝ 10.000 h, V-VTA 100 ➝
8.000 h and V-VTA 140
➝ 4.000 h
NOTICE
These greasing instructions are valid for operation
at 20°C ambient temperature. At 40°C these should
be reduced by 50 %.
To lubricate the inlet grating (Fig. 4/G) must be un-
screwed.
We recommend the following brands of grease:
KlüberPetamoGY193 or other equivalent greases
(see also grease recommendation plate (Fig. 4/M)).

Blade check:
V-VTA models have 4 carbon blades that gradually
wear out during operation.
First check after 4,000 operating hours and then
every 1,000 operationg hours or, depending on the
height (Fig. 6/X) earlier.
Remove inlet grating (Fig. 4/G). To remove the end
cover (Fig. 5/b) from the housing, the bolt (Fig. 5/a)
located in the centre of the bearing cover (Fig. 5/c)
should be removed. To achieve this one of the fi x-
ing bolts (Fig. 5/s) from the housing cover should be
screwed into the thread in the centre of the bearing
cover. Remove the blades (Fig. 6/d) to be checked.
All blades on the machine must have a minimum
height (Fig. 6/X) of more than 38 mm.
The blades must only be changed as a set.
