5.0 INTRODUCING LUBRICANT OIL AT THE FIRST
USE
Linear motion exciters are supplied without lubricant oil. After
fixing the exiter and before driving the exciter it's necessary to
introduce the lubricant oil.
Before introducing lubricant oil fix the breather cap in the suitable
position indicated in the figures 1, 2, 3, 4, 5 in page 38, based
on the exciter position respect to the horizontal.
Except for positions included in figure 5, the breather cap has
to be always assembled with the 90° elbow M/F. Before screwing
the 90° elbow M/F in the body, apply a relevant quantity of teflon
tape on the thread.
Before introducing lubricant oil, for 180° position (fig.3 page
38) it's also necessary to place the glass plug in one of the D
points.
The user is responsible for introduction of lubricant oil in the
exciter. This operation has to be carried out when the power
supply of the drive motor is disconnected.
The oil quantity to be introduced in the exciter depends on the
angle of inclination of the exciter respect to the horizontal (see
table in page 38). The oil level can be determined by using the
dipstick supplied together with the exciter.
Keep the oil dipstick always in proximity of the vibrating machine
and exciter.
Remove the oil dipstick before operating the linear motion exciter.
The recommended oil type depends on the service temperature
of the exciter or on the ambient temperature, in the table at page
40 are indicated different types of oil with some suggestions
for different oil manufacturers.
Use only good quality lubricant oil in compliance with relevant
standards.
For the different exciter types, following the angle of inclination of
the exciter respect to the horizontal surface, move the nuts on the
dipstick to set X and Y positions, as in table at page 39.
As example for exciter type VU 23000/6-S08 mounted with an angle
of inclination of +75° (see page 38), the X dimension on the dipstick
has to be 557mm, while the Y dimension has to be 22mm.
From figures 1, 2, 3, 4, 5 in page 38, corresponding to the different
exciter positions, are put in evidence the following points:
A - Breather cap +90° elbow M/F
B - Oil dipstick
C - Plug for oil drain (drain plug)
D - Glass plug for visual level. To be used only in 180° position:
remove plug from one of the D points and replace it with the
glass plug included in the supply; introduce oil till the oil is just
over the glass plug.
In the figures 1, 2, 3, 4, 5 at page 38, are shown the different positions
to be used for the oil dipstick, unscrew the plug in the corresponding
position and introduce the oil dipstick.
From the same hole used for the oil dipstick fill oil till the
oil level reach the nuts fixed on the dipstick.

MAX OIL LEVEL
MINIMUM OIL LEVEL
5.1 TIME INTERVALS FOR OIL CHANGING
First oil change recommended after about 500 operating
hours.
Subsequently we recommend oil change every 1000 operating
hours or maximum three months.
Check oil level at least once a month. If a reduced level is found
proceed to fill oil at the correct level.
The exciter life increase with more frequent oil changes.
5.2 LUBRICANT OIL CHANGE
The lowest plug in the exciter body have to be used for oil drain, see
plug C in the figures 1, 2, 3, 4, 5 in page 38 for the different angle of
inclination of the exciter when mounted on the machine.
Unscrew the oil drain plug and collect old oil waiting the complete
exciter emptying.
The plugs are magneticly to collect metal particles created by gears
contact. Before screwing again the plugs clean them by the metal
particles.
ATTENTION: Replace seals every time the plugs are removed.
Otherwise there is danger of oil losses and consequent damage
to the exciter.
After complete emptying and plugs cleaning, screw again the
plugs.
If the old oil is in bad conditions we recommend to reduce the inter-
val time for oil change. Infact the mentioned above timing it's just
indicative, the oil life depends by the type of oil used and by the
operating temperature. Set time intervals also on consultation with
oil manufacturer.
ATTENTION: Old oil disposal have to be carried out in respect
of the Laws and Regulations in force in the country of use,
with particular reference to the Laws regarding environmental
protection and pollution.
Fill new oil following same indications at paragraph 5.0.
ATTENTION: The dipstick is only used to check oil level and must
be replaced with a screwed plug for operating the exciter.
ATTENTION: Don't mix mineral oil with synthetic oil.
ATTENTION: Be sure the filled oil is new, in compliance with
the requirements and specifications described in paragraph 5.0
and contamination free by particles and other.
ATTENTION: Before changing from a type of oil to another type,
be sure the exciter is completely empty and all old oil has been
drained. Don't mix different oil types in the exciter, oil features
get worse in case of oil mixing.
WARNING: When the oil level is lower the minimum oil level
detectable by the dipstick, the exciter it's not anymore correctly
lubricated, there is heavy risk of breakage.
