Checking Wheel Coplanarity

1.DISCONNECT BANDSAW FROM POWER!

2.Remove the table assembly from the machine.

3.Make sure the blade is correctly installed and tensioned.

4.Hold a self-made coplanarity gauge (see Figure 50) close to the center of both wheels, making sure that the gauge fully extends across the wheels as shown in Figure 50.

—If the wheels are coplaner (in the same plane), the gauge will evenly touch the top and bottom of both wheels.

—If the wheels are NOT coplanar, place the coplanarity gauge on the upper wheel first, ensuring that it touches both the top and bottom rim. Then adjust the lower wheel to be coplanar with the upper wheel.

Note: The upper wheel of the Model G8146Z can also be adjusted. To do this, refer to the detailed instructions later in this subsection.

Adjusting Lower Wheel

1.Check the coplanarity of the wheels as outlined above, then identify the four wheel adjusting assemblies of the bottom wheel (see Figure 51).

Note: The lower wheel adjusting assemblies have a locking hex bolt threaded into an adjusting sleeve.

2.Use a 17mm wrench to loosen the locking hex bolts.

3.Use a 21mm wrench to loosen or tighten the adjusting sleeves as necessary to bring the lower wheel coplanar with the upper wheel.

Example 1: If the top of the lower wheel leans to far forward (see the top right exam- ple in Figure 50), thread the top two adjusting sleeves out.

Example 2: Alternately, if the lower wheel is parallel to the upper wheel but behind the plane of the upper wheel (see bottom right example in Figure 50), then thread all four adjusting sleeves in.

4.Re-tighten the locking hex bolts to secure the settings of the adjusting sleeves.

5.Re-check the wheels for alignment and repeat the steps above if necessary.

6.Re-check the pulley alignment and V-belt tension (Page 41).

7.Re-install the table and check its alignment with the blade (Page 44).
