To align the guide blocks:
1. rotate the wheels by hand and watch how
the blade feeds through the blade guides.
—if the blade feeds through the blade guide
without touching the guide block or rotat-
ing the support wheel, no adjustment is
necessary.
—if the blade rotates the support wheel but
does not touch the guide blocks, go to
Adjusting the Support Wheel on
page 43.
—if the blade rubs against the guide blocks,
continue to the next step.
2. loosen the vertical adjustment bolts shown
in figure 57 if the blade is not centered verti-
cally in the guide slot.
These instructions present
a serious injury hazard if
done while the machine
is connected to power. DO
NOT connect to power until
instructed!
