Vibration frequency and operation
speed
The vibrations in the product are caused by eccentric
elements. There is a centrifugal clutch between the
eccentric elements and the engine. This means that at
idle speed there are no vibrations in the product. When
the engine speed increases, the clutch engages and the
vibrations start. The vibration frequency decreases if the
engine speed decreases and stops fully when the
engine is at idle speed. Thus, the throttle control sets the
engine speed and also the vibration speed.
It is necessary to adjust the vibration frequency to the
condition of the concrete slump. For low water content in
the concrete slump, a higher vibration frequency is
necessary. For high water content in the concrete
slump, a lower vibration frequency is necessary.
Differences in the speed of the movement and the
vibration frequency gives different results.
To start the product
1. Open the fuel valve.
2. Set the choke control in the correct position.
