ADJUSTING VIBRATIONS
The vibration frequency of the screed is set at the factory at 12,000 vpm’s. Should it
become necessary to adjust the vibration, use the instructions below only after
consulting your dealer or the factory.
Place a 2x4 against the bend and strike the
end with a 6lb. to 8lb. hammer firmly. NOTE:
The shaft should never be bent over 1/8" or
damage to the screed may result. Use ex-
treme caution when bending. Check the
shaft before operating the screed.
If the screed shaft bent too much you can
lessen the bend. Rotate the bend in the shaft
towards you and use a 2x4 as described in
#3.
If the screed is not finishing properly,
pulling or tearing the concrete, check the
engine speeds. The correct RPM setting is
3,450 to 3,600. If the engine RPM’s are
correct, the screed shaft can be adjusted,
within reasonable limits, to increase
vibration force.
Rotate the screed shaft at the point
between the bearing housings where
adjustment is needed. You will notice a
slight bend in the shaft. Turn the shaft so
that the bend is down or away from you.
