Exciter Adjustment
Overview
Proper operation of the screed produces a creamy liquid around the blade during
strike-off. If a creamy liquid does not form at the standard throttle range of one-half
to three-quarters speed (6000–7000 rpm), or with slight speed increases, then
adjust the exciter.
Procedure
Perform the procedure below to adjust the exciter.
1. Remove the 4 screws
(a)
mounting the blade to the power unit.
2. Remove the 3 screws mounting the eccentric housing
(b)
.
3. Using a 1/4-inch Allen wrench, loosen the screw
(c)
holding the adjustable
eccentric weight in place.
4. The screed eccentric is preset at the factory to Position 2 as shown. Rotate the
exciter to the right for less vibration, or to the left for more vibration.
Note:
The maximum vibration exciter setting is Position 1. The minimum exciter
vibration setting is Position 3.
5. Reassemble components and tighten all hardware.
