is approximately .003"
4.Turn nut (B, Fig. 16) to adjust the eccentric bearing snug to the blade. Blade should still move up and down freely when grasped as in
Fig. 17. Warning! Make sure power is disconnected and hands are protected before handling blade. ~e sure that the blade teeth do not interfere with the roller bearings.

Adjusting Bow Weight
Bowweight is one of the most important adjustments of the saw. If the bow weight is not set properly, one can expect poor performance, crooked cuts, tooth stripping, stalling, and the blade popping off the blade wheels. The hydraulic feed rate unit will not compensate for improper bow weight. Bow weight has been set at the factory and should not need adjustment. If adjustment is necessary:
1.Disconnect the machine from the power source.
2.Turn the hydraulic cylinder valve on and place the the saw arm in horizontal position.
3.Turn feed rate valve on hydraulic cylinder
