Eccentric Weight Adjustment
The eccentric weights may be adjusted to produce the desired centrifugal force output. It is
always best to operate the electric vibrator at the lowest weight setting that produces the desired
result. This will result in lower energy expense and extend the bearing life. The factory setting
is 50% which would result in 50% of the centrifugal force noted on the nameplate. To adjust the
force output, lockout/tag out the electric vibrator. Remove each weight cover and set it and the
screws, washers and O-rings aside. The outer adjustable weight clamping screw or the shaft nut
may be loosened and then the adjustable weights may be rotated to the desired position.
Reference Figure 10.
The eccentric weights must be adjusted to mirror images of each other at the same setting
number as shown in Figure 11.
Properly torque the clamping screw or shaft nut to secure the weights in position. Torque values
are outlined in the Appendix. Reinstall the weight covers making sure not to pinch the O-rings.
