Sawmill Alignment

After tightening the blade guide arm rollers, check that the arm is aligned properly.

With the arm adjusted 1/2" (13 mm) from fully closed, measure the distance between the
blade guide roller flange and the back of the blade.

See Figure 7-32.

Adjust the blade guide arm to 1/2" (13 mm) from fully open and remeasure the distance
from the roller flange to the back of the blade. The two measurements should be the
same. If not, adjust the inner rollers in or out to tilt the arm horizontally.

See Figure 7-33.

To tilt the arm out away from the blade, loosen the front nuts on the

inner rollers and tighten the rear nuts. To tilt the arm in toward the blade, loosen the rear
