Pioneer PNR 14-150 operation manual Table Parallelism Inspection

Table Parallelism

Your Pioneer planer is pre-set parallel at the factory and should rarely need adjustment. However, in the instance that lumber is not parallel in width follow the adjustment procedures.

Table Parallelism Inspection

1Disconnect from power source before performing any adjustments.

2Table parallelism adjustments less than .016” (the difference in thickness from one side of the board to the other)

3Loosen the caps screws that hold the head cast- ing in position. (Figure 32) Move the casting up or down to the proper position and tighten. See figure 33 and 34. Plane another test piece.

Adjusting Table Parallelism

If the variance is greater than .016” you will need to turn the column sprockets to adjust parallelism.

1You first need to gain access to the sprockets by tilting the planer on its side. ! WARNING: The planer is very heavy and should not be tilted by one person or by hand. Use proper lifting methods.

2	Loosen the 2 bolts that hold the idler sprocket which	Idler
	places tension on the chain. (Figure 35)	Sprocket
3	Remove the chain from the sprocket that needs to be
	adjusted.

4Turn this sprocket by hand either left or right depending on which way the adjustment is needed. Adjust this sprocket to be the same as the other 3. One tooth will usually be enough to make the adjustment.

5 Turning the sprocket clockwise will reduce the distance	Lock Bolts
between the head casting and the table and turning the
sprocket counter-clockwise will increase this distance.	Figure 35
