MAINTENANCE PROCEDURES
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, which are good for ambient
temperature ranging from - 55°C to 120 °C.
1. Lube Fitting
2. 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.

ADJUSTABLE MOTOR BASE
The motor base adjusting screw (see figure below) should be coated
every six months using a good quality corrosion inhibiting grease,
such as one of those recommended for lubricating the fan shaft
bearings.
