Blade Changes
To remove the blade:

2. Release the tension on the blade by turning
the tension control knob counterclockwise.
3. Remove the upper guide assembly from the
support bar by loosening the hex bolt shown
in
Figure 25
.
4. Adjust the lower guide bearings away from
the blade.
5. Put on leather gloves to protect your hands
from the sharp teeth of the blade.
Caution—the blades are sharp!
6. Open the upper and lower wheel covers and
slide the blade off both wheels.
Wear gloves and safety goggles when han-
dling blades. Coiled blades spring open as
they are uncoiled and could cause deep
cuts or lacerations.
Always disconnect
power to the machine
when changing blades.
Failure to do this may
result in serious person-
al injury.
To replace the blade:
1. Put on leather gloves to protect your hands
from the sharp teeth of the blade.
2. Slide the blade through the table slot, ensur-
ing that the teeth are pointing down toward
the table.
If the teeth will not point downward on the
right hand side, the blade is inside-out.
Remove the blade, and twist it right side-out.
3. Slip the blade through the lower guides, and
mount it over the upper and lower wheels so
the blade is centered on the wheels.
4. Mount the upper guides by sliding the blade
between the guide bearings and then guide
the bearing bracket onto the guide post. Use
care when aligning the guide assembly so
that it does not twist the blade.
5. Apply tension, then check and adjust track-
ing as described in the section titled Blade
Tracking.
6. Adjust the upper and lower guide blocks and
support bearings.
7. Close and latch the wheel covers.
