3 - ROUTINE MAINTENANCE
Checks after start-up
After approximately 50 hours’ operation, check that the screws
fixing the motor and the coupling device are still tight.
In the case of chain or belt transmission, check that the tension
is correctly adjusted.
Cleaning
To ensure the motor operates correctly, remove any dust or
foreign bodies which might clog the cover grille and the housing
fins.
Precaution: before carrying out any cleaning operation check
that the motor is completely sealed (terminal box, drain holes,
etc).
Dry cleaning (vacuuming or compressed air) is always
preferable to wet cleaning.
Always clean at reduced pressure from the center
of the motor towards the extremities to avoid
introducing dust and particles under the seals.
Draining off condensation water
Temperature variations cause condensation to form inside
the motor, which must be removed before it adversely affects
motor operation.
Condensation drain holes, located at the bottom of the motors
(bearing in mind their operating position) are sealed with plugs
which must be removed and then replaced every six months (if
they were not replaced, the motor degree of protection would
no longer be maintained). Clean the orifices and plugs before
reassembling them.
Note: In conditions of high humidity and significant temperature
variations, a shorter period is recommended.
As long as it poses no risk to the motor protection, the
condensation drain plugs can be removed.
3.1 - Greasing
3.1.1 - Type of grease
When the bearings are not greased for life, the type of grease
is indicated on the nameplate.
As standard this grease is Polyrex EM103 and we recommend
that it is used for subsequent lubrication.
Avoid mixing greases.
3.1.2 - Permanently greased bearings
For LS/LSES and FLS/FLSES ≤ 225 motors , the bearings
defined offer long grease life and therefore lubrication for the
lifetime of the machines. The grease life according to speed of
rotation and ambient temperature is shown on the chart below.
