general information
NOTICE
Vibrator head spacing distance (D) is calculated by multiplying the vibrating head radius (area of influence) by 1.5.
When determining which head to choose it is important to access the application; mainly the dimensions of the application. Select the vibrator head based on its radiating radius characteristics. Refer to Table 4.
Select the vibrating head that covers the largest possible area without excessive overkill. This will allow for more efficient productivity. General rule of thumb is: DO NOT select a vibrator head which has a vibration radius of more than twice the width of the form.
Example:
If the form width is 9 inches (229 mm) the selected vibrator head radius should not exceed an 18 inch (457 mm) radius.
In this example the 2600HD vibrator head would be the recommended choice. Refer to Table 4 and Figure 3.

EXTENSION CORDS
When extension cords are used, refer toTable 5 for the correct size and lengths needed. Using an extension cord with a wire gauge smaller than or longer than the recommended size could result in reduced motor performance and/or damage to the motor or extension cord due to overheating.
