When a new V-belt is fitted, the tension must be checked after the fan
has been started up 10 times and adjusted if necessary.
If the product is stored and/or shut down over longer periods (longer
than 6 months), the belt drive must be given slack so that the fan
bearings are not subject to any unnecessary punctual permanent load.
7.2.9 Lubricating the fan bearings
Two different versions are fitted:
• Variant with lubrication nipple:
The fan bearings must be lubricated, initially after a short run-in phase
and thereafter at regular intervals, every 6 months or every 12 months at
the latest.
In each case, approx. 10 g will be greased. This is equivalent to approx. 8
x 1.2 g strokes using a standard grease gun. If measured lubrication is
not possible, grease until lubricant escapes from the bearing.
• Variant without lubrication nipple:
If no lubrication nipple is visible on the bearing, the version being used
is a fan with lifetime lubrication. In this case no lubrication is necessary.
7.2.10 Checking the compressed air container with
compressed air safety valve
The product has one or more compressed air containers with
compressed air safety valve.
Products with compressed air container and safety valve must be
serviced/checked according to current national regulations.
