Checking Blade Tracking
"Tracking" refers to how the blade rides on the
sawmill wheels. Proper tracking is important for
achieving correct blade tension and cutting accu-
rately. Improper tracking reduces cutting accura-
cy, causes excess vibration, and places stress on
the blade and other components. The orientation
of the wheels in relation to each other determines
how the blade tracks.
Saw blades are sharp and
may cause lacerations. To
reduce the risk of injury,
wear leather gloves when
handling saw blades.
Wear safety glasses when
handling blade.
To check blade tracking:
1.
DISCONNECT MACHINE FROM POWER!
2.
Turn blade cover lock knobs clockwise to
open blade covers (see Figure 68).

3.
Center blade on wheels, then tension blade
(see Tensioning Blade on Page 36).
4.
Rotate wheels by hand and observe blade
position. Blade should track in center of
wheels and blade gullets should track about
" in front of blade guides (see Figure 69).

Adjusting Blade Tracking.
Adjusting Blade Tracking
If blade tracking is out of alignment, the left wheel
shaft can be adjusted.
If adjusting the wheel shaft does not improve blade
tracking, adjust the blade guides, as blade guides
out of adjustment can make the blade wobble or
wander. If the blade is properly tensioned, the
blade guides have been properly adjusted, and
adjusting the wheel shaft still does not improve
blade tracking, replace the blade. A worn blade
can become "bell mouthed" and throw off wheel
coplanarity just enough to cause problems.
