8.2.5.3 Machines with textile fan covers
In order to guarantee an essentially unobstructed flow of cooling air containing fluff, remains
of materials or similar dirt, machines with a fan cover for textile applications have a larger air
discharge cross-section between the edge of the cover and the cooling ribs of the machine
frame.
These machines have a warning sticker on the fan cover.
8.2.6 Stoppages
Longer non-operational periods
Note
•
For longer non-operational periods (> 1 month), either operate the machine or at least
turn the rotor regularly, approximately once per month.
• Please refer to the section "Switching on" before switching on to recommission the motor.
•
Remove any machine rotor locking devices before you turn the rotor.
NOTICE
Restricted motor function
If not used for longer periods of time, material damage or complete motor failure can occur.
If the motor is out of service for a period of more than 12 months, then environmental
effects can damage the motor.
•
Apply suitable corrosion protection, preservation, packing and drying measures.
Switching on the anti-condensation heater

Lubricating before recommissioning
NOTICE
Dry running bearings
Bearings can be damaged if they do not have sufficient grease.
• Re-grease the bearings if they have been out of service for more than one year. The
shaft must rotate so that the grease can be distributed in the bearings. Observe the data
on the lubricant plate.
