ASSEMBLY
TRACKING THE BLADE
See Figure 10.
NOTE: Adjust blade tension properly before making tracking
adjustments. Check that the blade guides are not interfering
with the blade.
To Adjust:

Open the front cover by releasing the upper and lower
latches. Watch the blade’s position on the upper tire
through the tracking view window as, by hand, you
slowly turn the upper wheel clockwise. If the blade moves
away from the center of the tire, the tracking must be
adjusted.
If the blade has moved left or right of center:
NOTE: It may be necessary to loosen the hex nut for a larger
range of adjustments. Be sure to retighten after adjusting.

Turn the blade tracking knob (clockwise if blade has
moved left and counterclockwise if blade has moved right)
while turning the wheel by hand until the blade moves
back and rides in the center of the tire.
 Check the position of the blade on the lower tire. The
blade should be completely on the tire. If not, adjust the
tracking until the blade is on both tires.
 Rotate the upper wheel by hand in a clockwise direction
for a few more turns. Make sure the blade stays in the
same location on the tires. Readjust, if necessary, until
blade is tracking properly.
 Close front cover and relatch.
NOTE: The 1/8 in. blade may not track properly in the center
of the wheel. It may be better to track this blade on the back
half of the upper wheel.
WARNING:
The blade guides have been preset at the factory.
These settings are functional for some applications. We
recommend that you check and adjust blade guide
settings before first use of your saw. Refer to “Adjusting
blade guide support, thrust bearings, and blade guide
bearings” procedures explained in the ADJUSTMENTS
section of this operator’s manual.
ATTACHING THE WORKLIGHT
See Figure 11.

Slide the worklight bracket into the slot at the back of the
band saw housing.
 Insert wing screw and tighten securely.
IMPORTANT SAFETY INSTRUCTIONS
This worklight has a polarized plug (one blade wider than
the other) as a feature to reduce the risk of electric shock.
This plug will fit in a polarized outlet only one way. If the
plug does not fit fully in the outlet, reverse the plug. If it still
does not fit, contact a qualified electrician. Never use with
an extension cord unless the plug can be fully inserted. Do
not alter the plug.
