1. When installing the blade retaining-bolt, ensure the threads of the bolt are
aligned with the threads of the drive shaft so as not to “cross-thread” the bolt.
2. When installing the blade ensure that the blade shaft and flanges are free from dirt
and all foreign material before mounting blade on the blade shaft. Tightening a blade
against an uneven surface can cause fracture or cause the blade to run out of alignment.
3. Blade shaft threads are left-handed on the right side of the saw and right-hand on the
left of the saw.
