ADJUSTMENTS
HEIGHT ADJUSTMENT TENSION SCREWS (Fig. 16 & 17)
The six height adjustment tension screws on the height adjustment wheel
side of the sander apply pressure to the sliding mechanism of the sand-
ing head. The tightness of the screws can be tuned to allow accurate and
smooth height adjustments.
If the screws are too loose, the drum will deflect during operation, causing
an uneven sanded surface. If the screws are too tight, adjusting the height
of the sanding drum will be difficult, causing excessive wear on the height
adjustment system. To adjust the height adjustment tension screws:
1. Turn off and disconnect the machine from the power source.
2. Loosen the two center lock nuts on both sides of the frame (Fig. 16 - 1).
3. Step to the motor side of the sander. Loosen or tighten the 6 cap
screws (Fig. 17 - 1) evenly in 1/4 turn increments. Rotate the height ad-
justment wheel to test the sanding head movement. Adjust the screws
until the desired fit and smoothness is achieved.
4. Re-tighten the two center lock nuts (Fig. 16 - 1).

CONVEYOR BELT TO DRUM ALIGNMENT (Fig. 18 & 19)
To achieve an even sanding result, the sanding drum and conveyor belt
should be parallel with each other. To check the belt to table alignment:
1. Make sure the height adjustment tension screws are properly adjusted.
Otherwise the testing results may not be accurate.
2. Prepare a planed board about 2" thick and 8 - 10" wide. Make sure the
thickness on both ends of the board is even.
3. Turn on the machine. Feed the board through the sander to take
several light cuts from the top surface of the board.
4. Measure the thickness of the left edge and right edge of the board.
The difference between the two edges should be less than 0.05".
5. Remove the two cap screws (Fig. 19 - 1) on the side of the conveyor
table that produces a thicker sanding result. Slide a metal shim (not in-
cluded) between conveyor table and the frame to slightly elevate the
conveyor table to reduce the sanding thickness on that side.
6. Tighten the cap screws to secure the conveyor table.
7. Repeat steps 2 to 6 as necessary until the alignment between the con-
veyor belt and drum is within 0.05" difference.
