7.2.9 Replacing/retensioning the fan belt drive
After 10 fan starts, the V-belt tension and the alignment of the V-belt
pulleys must be checked for the first time.
We recommend replacing the V-belts every 1,600 operating hours or after
12 months at the latest.
Please proceed as follows when tensioning/replacing the V-belt:
1. Switch the product off at the I/O key and set the main switch to the O
position. Secure the main switch with a padlock.
2. Now open the fan maintenance cover to access the belt drive.
3. Make sure a new V-belt is available.
4. Release the tension on the motor tensioning carriage and remove the
V-belt(s).
5. Check the V-belt pulleys for unusual wear or significant damage. If
necessary, use a disc groove gauge for checking.
6. Insert the new V-belt and pretension the motor tensioning carriage.
7. Move the V-belt by hand for several revolutions.
