"Blade tracking" refers to how the blade rides on
the wheels. When tracking correctly, the blade
rides just next to, but not touching the wheel
flange. Blade tracking is primarily controlled by
adjusting the upper wheel tilt.
Another way to track the blade is known as
"Coplanar tracking." Coplanar tracking involves
aligning the wheels so they are parallel and
aligned (see
Wheel Alignment on page 40).
When wheels are coplanar, vibration and heat are
reduced during operation.
Blade Tracking
To adjust the blade tracking:
1. open the upper wheel cover and familiarize
yourself with the wheel, the wheel flange, the
blade, and the relationship between the blade
and wheel flange (
figure 42).
Blade tracking on the Model G0659 must be
adjusted with the saw running. To reduce the
risk of serious injury, keep hands clear from
all moving parts and touch only the parts
indicated in the following instructions. In
addition, wear eye protection whenever the
machine is running.
