Grizzly G0621 Dust Collection Blade Tracking, To connect a vacuum hose, To center track the blade

Dust Collection Blade Tracking

This saw creates substantial amounts of fine dust while operating. Failure to use a vacuum system can result in respiratory illness.

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 21⁄2" 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.

3.Close stand door and fasten it shut with the stand door knob.

"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.
