G0621 Wood/Metal Bandsaw
-17-
"Blade Tracking" refers to how the blade rides on
the wheels. When tracking correctly, the blade
rides in the center of the rim part of the wheels.
Blade tracking is primarily controlled by adjust-
ing the upper wheel tilt. Tracking the blade in
this manner is referred to as "Center Tracking,"
because you tilt the wheel until the blade rides in
the center.
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 42).
When wheels are coplanar, vibration and heat are
reduced during operation.
The wheels on the Model G0621 are factory
aligned, so center tracking is the only adjustment
that needs to be performed during setup.
To center track the blade:
1. DISCONNECT BANDSAW FROM POWER!
2. Adjust the upper/lower blade guides and sup-
port bearings away from the blade.
3. Open the upper wheel cover.
4. Adjust the blade tension by matching the size
of the installed blade with the equivalent mark
on the blade tension scale (located on the
back of the bandsaw).
5. Spin the upper wheel by hand at least three
times and watch how the blade rides on the
crown of the wheel. Refer to
Figure 19 for an
illustration of this concept.
—If the blade rides on the peak of the upper
wheel crown
, then the bandsaw is already
tracked properly and no additional adjust
-
ments are needed. Skip to Step 9
.
—If the blade does not ride in the peak of the
upper wheel crown, then continue with the
next step.
Blade Tracking
Connect this machine to a shop vacuum rather
than a dust collector. Most dust collectors are not
designed to capture metal shavings and doing so
may lead to a fire. If you are in doubt about the
capabilities of your shop vacuum or dust collector,
refer the owner's manual before connecting it to
this machine.
To connect a vacuum hose:
1. Fit the 2
1
⁄2" dust hose over the dust port, as
shown in
Figure 18, and secure in place with
a hose clamp
.
2. Tug the hose to make sure it is snug.
Note: A tight fit is necessary for proper per-
formance.
This saw creates substantial amounts of fine
dust while operating. Failure to use a vacuum
system can result in respiratory illness.
