NOTICE:
Risk of equipment damage. Ensure that the grease container, the greasing device, and the fit-
tings are clean. Failure to do so can result in impurities entering the bearing housing while re-
greasing the bearings.

1.
Wipe dirt from the grease fittings.
2.
Remove the two grease-relief plugs on the bearing housings.
3.
Fill both of the grease cavities through the fittings with a recommended grease until the fresh
grease comes out of the relief holes.
4.
Run the pump for about 30 minutes or until grease no longer comes out of the housing.
5.
Reinstall the grease-relief plugs.
6.
Wipe off any excess grease.
7.
Recheck the alignment.
The bearing temperature usually rises after you regrease due to an excess supply of grease. Tempera-
tures return to normal in about two to four operating hours as the pump runs and purges the excess
grease from the bearings.
6.3.1.1 Lubricating-grease requirements
Grease-lubricated ball bearings are standard on this model. A grease-lubricated bearing can be identified
by grease fittings located on the bearing housing.
Precautions
NOTICE:
•
Avoid equipment damage or decreased performance. Never mix greases of different con-
sistencies (NLGI 1 or 3 with NLGI 2) or with different thickeners. For example, never mix
a lithium-based grease with a polyurea based grease. If it is necessary to change the
grease type or consistency, remove the rotor and old grease from the housing before re-
greasing.
•
Remove the bearings and old grease if you need to change the grease type or consisten-
cy. Failure to do so may result in equipment damage or decreased performance.
