7.Tighten the tension handle as tight as necessary so the blade will not slip on the wheels during start up.

8.Put the gearbox in neutral by moving the gear change knob between two of the speed posi- tions.

9.Spin the wheel by hand until the blade resumes the previous tracking.

10.Put the gearbox back in gear.

—If the tracking needs to be adjusted, refer to the Tracking procedure in the next sec- tion.

—If the tracking is fine, proceed to Blade Tension on Page 34.

Blade Tracking

The blade tracking has been properly set at the factory. The tracking will rarely need to be adjusted if the bandsaw is used properly.

To adjust the blade tracking on the bandsaw:

1.UNPLUG THE BANDSAW!

2.Raise the bandsaw to the highest position and close the feed rate ON/OFF valve.

3.Remove both blade guide assemblies.

4.Open the wheel access cover.

5.Loosen, but do not remove the lower cap screw in the blade wheel tilting mechanism (Figure 37).

6.

Relax the blade tension.

7.

Adjust the tracking set screw with a 4mm hex

 

wrench as shown in Figure 37, then tighten

 

the cap screw loosened in Step 4.

 

—Tightening the set screw will move the

 

blade closer to the shoulder of the wheel.

 

—Loosening the set screw will move the

 

blade away from the shoulder.

8.

Tension the blade.

9.

Put the gearbox in neutral by moving the

 

gear change knob between two of the speed

 

positions and spin the wheel by hand.

 

—If the blade tracks along the shoulder of

 

the wheel (without rubbing), the blade is

 

tracking properly and this adjustment is

 

completed.

 

—If the blade drifts away from the shoulder

 

of the wheel or hits the shoulder, repeat

 

Steps 4-7.

10.

Replace the blade guard and blade guide

 

assemblies.

11.

Adjust the blade guides as needed. Refer to

 

Blade Guide Bearings on Page 35.
