Standard fan congurations ship with fan bearings factory
lubricated (ready for start-up). The fan should be turned off
and locked out to prevent accidental start-up of the fan during
lubrication procedures. Also, secure sheaves before servicing
the unit to ensure that the fan cannot freewheel. Failure to
do so may result in severe personal injury.
Proper lubrication of bearings helps to assure maximum
bearing life. Generally, lubricate bearings every 1,000 hours of
operation or more frequently when exposed to wet location,
wide temperature variety or severe atmospheric conditions.
Add grease with manual grease gun until a light bead of grease
appears at the bearing grease seal or refer to lubrication
frequency in the Tables 1, 2 & 3. Observation of the condition
of the grease expelled from the bearings at the time of re-
lubrication is the best guide as to whether lubrication intervals
and the amount of grease added should be altered. Always
lubricate bearings prior to extended shutdown or storage and
rotate shaft monthly.

A Lithium / Petroleum base grease conforming to an NLGI
Grade II consistency is normally used. Lubricant must be free
of any chemical impurities such as free acid or free alkali,
dust, rust, metal particles or abrasives. This light viscosity,
low torque grease is rust inhibited and water resistant, has a
temperature range of -30°F to +200°F with intermittent highs
of +250°F. Lubricate bearings as required by the severity of
required duty.
