BLADE TRACKING
The blade tracking means where the blade
rides on the upper and lower wheels. It
should always be centered on both wheels.
Although the blade tracking of this band
saw is factory set you should check it again
to make sure that the blade is centered on
the wheels. The misalignment of the blade
can be controlled by adjusting the upper
wheel tilt lock nuts.
Disconnect the machine from power (if
connected) and open the upper wheel
cover. Rotate the upper wheel by hand
slowly and see how the blade rides on the
wheel.
If the blade is not properly aligned and
needs to be adjusted, loosen the lock nuts
shown in figure-11 and turn the knobs.
Figure-11 Knobs and Locks Nuts
TURN KNOBS CLOCKWISE:
If the blade moves towards the front edge
of the wheel. It makes the top of the wheel
to tilt back and moves the blade towards
the center.
TURN KNOBS COUNTER-CLOCKWISE:
If the blade moves towards the back edge
of the wheel. It makes the top of the wheel
to tilt to the front and moves the blade
towards the center.

When you have adjusted the blade tracking,
retighten the lock nuts.

IMPORTANT
In very rare cases if the blade tracking is
not adjusted by tilting the upper wheel,
then you will have to make minor
adjustments to the angle of tilt of the
lower wheel. Loosen the four hex bolts
and rotate the sleeves to tilt the lower
wheel to get the proper angle of tilt and
tighten the bolts back. Remember, this
adjustment is done only if the blade
tracking is not adjusted by tilting the
upper wheel.
