G0640X 17" Wood/Metal Bandsaw

-17-

Blade Tracking

Serious personal injury

can occur if the machine

starts while your hand

is touching the bandsaw

wheel during tracking

adjustments. Disconnect

power from the bandsaw

before performing blade

tracking adjustments.

"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 47).

When wheels are coplanar, vibration and heat are

reduced during operation.

The wheels on the Model G0640X 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. Make sure the upper and lower blade guides

are adjusted away from the blade.

3. Engage the quick tension lever and turn the

blade tension handwheel until the tension

scale (

Figure 18) reads between 4 and 6.

The cast iron spokes may have sharp edges

and the blade teeth may extend beyond the

edge of the wheel, creating a laceration haz

ard. In the next step, be careful when turn

ing the wheel by hand.

4. 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 in the center of the

upper wheel and is centered on the peak

of the wheel crown, then the bandsaw is

already tracked properly and no further

adjustments are needed at this time.

—If the blade does not ride in the center

of the upper wheel and is not centered

on the peak of the wheel crown, then

continue with the following steps.
