LUBRICATION
The bearings at the drive shaft end of the blower are grease lubricated. The timing gears and bearings at the other end
are lubricated by the lower timing gear (when in the horizontal flow configuration) acting as a oil slinger, carrying oil to
the upper timing gear and providing splash lubrication for the bearings. Both timing gears act as stingers when the
blower is in the vertical flow configuration.
Use a good grade industrial type anti-rust, oxidation and foam inhibited, non-detergent oil.
FILLING PROCEDURE
To fill the gear housing, remove the oil breather* (A) and oil level plug (B) on the gear end. Fill the gear housing until
oil drips out of the oil level hole. Replace plugs in their respective holes.
*Models 2002 and 2004 do not have oil breathers. In this case, remove plug to fill.
WARNING:
Do not start the blower until you are sure oil has been put in the gear housing.
GREASE LUBRICATED BEARINGS
Service drive end bearings at regular intervals. (See "Suggested Lubrication Intervals for Grease Lubricated Bearings"
below.) Use NLGI #2 premium grade, petroleum base grease with high temperature resistance and good mechanical
stability Using a pressure gun, force new grease into each bearing until traces of clean grease come out of the relief
fitting.
CAUTION:
To avoid blowing out the drive shaft seal, do not inject grease too rapidly.

LUBRICATION INSTRUCTIONS FOR
OIL LUBRICATED GEARS AND BEARINGS
Add fresh oil as required to maintain proper level. Drain
and refill after the first 100 hours of operation and
thereafter every 1,000 hours of operation under normal
service, more frequently depending on the type of oil
and oil operating temperature. Use a good quality oil.
