NOTICE
Whenever changing a blade or adjusting ten-
sion and tracking, the upper and lower blade
support bearings and guide blocks must be
properly adjusted before cutting operations.
Figure 23. Correct support bearing positioning.
The blade guides support the sides of the blade
while a cutting operation is being performed. The
blade guides are designed to be adjusted in two
ways—forward/backward and side-to-side.
Proper adjustment of the blade guides ensures
accurate cuts by eliminating back-and-forth blade
flex. There is a set of blade guides both above
and below the table.
To adjust the upper and lower blade guides:
1. Disconnect the machine from the power
source!
2. Loosen the hex nut shown in Figure 24.
