13.2 - Oil change
Execute the oil change with
machine at rest
and
cold gear reducer
.
Pre-arrange a proper tank system for the drain oil, unscrew the drain plug and the filler plug to facilitate
the drain; make sure that all oil has been drained, inclining the gear reducer of removing any residual parts
with a suction pump; dispose the drain lubricant according to the laws in force.
– wash the inside part of gear reducer housing using the same oil type suitable for the running; the oil used
for this wash can be applied for further washings after proper filtering by 25
µ
m of filtration standard;
Fill the gear reducer with oil again
up to level
.
The exact quantity gear reducer is to be filled with is definitely
given by the level
. For EP series gear
reducers, when output speed
n
2
is lower than 0,3 min
-1
, for all mounting positions refer to approximative
oil quantities stated for position V1.
During the oil change, replace the seal rings.
In this case, the new ring must be positioned so that it does not work on the same point of sliding contact
as the previous ring;
When dismounting the cap (whenever gear reducers are provided with), reset the sealing with adhesive on
cleaned and degreased mating surfaces.
For lubrication interval see table 8.2.
Indiependently from running hours: replace or regenerate synthetic oil at least each 5
÷
8 years, according
to gear reducer size, running and environmental conditions.
Never mix different makes of synthetic oil
; if oil-change involves switching to a type different from that
used hitherto (see ch. 8), than give the gear reducer a through clean-out.
13.3 - Coil and internal heat exchanger
In case of long non-running periods at ambient temperatures lower than 0 °C, the coil should be emptied
out using compressed air to blast out all the coolant, so as to avoid freezing-up which would cause the coil
to break.
Verify that there are no deposits inside the coil which may obstruct water circulation or affect cooling. If
any, wash the coil with suitable chemical cleaning products or consult Rossi.
Check the internal heat exchanger periodically and proceed with the cleaning of exchange surfaces taking
care not to damage the finned surfaces-
