Lubrication
FAN SHAFT BEARINGS
The fan shaft is supported by ball bearings (see figure below).
Under normal operating conditions the bearings should be greased every 2000 operating hours or at least every six
months. The bearings should be lubricated with one of the following water resistant inhibited greases (or an
equivalent), which are good for ambient temperature ranging from -20°C to 120°C or an equivalent.

Locking collar
The bearings should be lubricated only with a hand grease gun. Do not use high-pressure grease guns, since they
may rupture the bearing seals. When lubricating, purge the old grease from the bearing by gradually adding grease
until a bead of new grease appears at the seal. In particular when extended lubrication lines are fitted ensure that
ALL old grease is removed and that new grease is leaving the seal.
For grease products see table below.
