In certain applications it is necessary to modify the location of the precleaner pole due to permanent obstacles that obstruct the desired location. Relocating the pole location can be done easily and does not hinder the performance of the cleaner as long as the “C” dimension is maintained.

NOTE: In the following example, we will be lowering the pole location in the “Y” direction, but the same method could also be applied in the “X” direction.

Conveyor situation:
Pulley Diameter: 60" (1500 mm)
X=26 3/8" (670 mm)
Y=27 1/4" (692 mm)
C=38" (965 mm)

1. Determine the given location dimensions and define the change needed. After laying out the given X & Y dimensions, determine the distance of the modification required for adequate clearance of the pole and tensioning system. (In the example, we decide to lower the pole 2" (50 mm) to clear the support structure).
    
2. Write down known dimensions. We can now determine two of the three required dimensions which will allow us to find the third. We know we cannot alter the “C” dimension, so this will remain the same. Also, we are required to lower the unit in the “Y” dimension 2" (50 mm), so we add 2" (50 mm) to the given “Y” dimension.
   
   X = ?"
   Y = 27 1/4" + 2 = 29 1/4" (692 mm + 50 mm = 742 mm)
   C = 38" (965 mm)
    
3. Determine final dimension. On a flat, vertical surface, using a level, draw one horizontal line and one vertical line, creating a right angle (Fig 3a). Measure down from the intersection the determined “Y” dimension and mark (Fig 3b). With the tape measure starting at the modified “Y” mark, swing the tape across the “X” line and mark at the “C” dimension where it crosses the “X” line (Fig 3c). Measure from the intersection to the “C” intersection and this will be your new “X” dimension (Fig. 3d).
   
   X = 24 1/4" (616 mm)
   Y = 29 1/4" (742 mm)
   C = 38" (965 mm)
