Each truss section has a set of pillow block bearings
(Figure 34) that will require lubrication. Lubricate the
grease fitting for each bearing every 40 hours of operation
using any grade lithium base grease

Orientation of the eccentric shaft weights (Figure 35)
must be aligned so that the fat side of the weight is in line
(parallel) with the drive shaft key way.
For proper vibration of the shaft, all eccentric weights must
be aligned identically.

Failure to keep bearings lubricated (greased) will
cause rotation of eccentric drive shaft to stiffen. To
prevent contamination of the bearing, always insert the
