G1052 9" Bandsaw
Tracking Blade Guides
Rotate the upper wheel several turns by hand.
Watch the lateral movement of the blade on the
tire. The blade will move back and forth slightly
until it finds its equilibrium position. If the blade is
tracking correctly, it will stay on both tires in one
location, not necessarily in the center of the
wheels. If the blade will not stay in one place on
the tires, check that the wheels are co-planar. If
they are co-planar, adjust the tracking, as fol-
lows:
1. Disconnect the bandsaw from the power
source and adjust the upper and lower guide
bearings away from the blade. See Blade
Guide adjustment section.
2. Decrease the tension slightly before adjust-
ing tracking. Tracking adjustment will auto-
matically increase the tension.
3. Loosen the lock knob (#22) on the tracking
control knob. Turn the tracking control knob
clockwise or counter-clockwise while turning
the upper wheel by hand until the blade
stays in one position. Figure 8.
4. Re-tighten the lock knob and check the
tracking. Repeat step 3 as needed.

Check the upper and lower support bearings and
guide bearings each time you start your band-
saw.
Always adjust the assemblies away from the
blade before installing a new blade or making
blade tracking adjustments. After blade tension
and tracking are set correctly, re-adjust the upper
and lower support bearings and guide bearing
assemblies into position.
The support bearings back-up the blade during
the sawing operation. Perform steps 1-3 for both
upper and lower support bearings. Both upper
and lower assemblies are identical. See Figure 9
for adjustment locations. To adjust support bear-
ings:
1. Loosen the setscrews (#33) securing the
support bearing shafts (#38).
2. Turn the knurled end of the support bearing
shaft to position the edge of the bearings
behind the blade. Push or pull the shafts so
that the upper and lower support bearings
are about 1/64" behind the blade.
3. Re-tighten the setscrews.
