Blade Tracking - Hafco Woodmaster BP-430A Operation Manual

4.9 BLADE TRACKING

To operate correctly, the saw blade does needs to run in the centre of the rubber tyre. If the
blade rides in the centre of the upper wheel and is centred on the peak of the wheel crown,
then the band-saw is tracking correctly and no adjustment is needed. If the blade does not
ride in the centre of the upper wheel and is not centred on the peak of the wheel crown, then
adjustment is required.
To check or adjust the tracking:
1. DISCONNECT THE MACHINE FROM THE POWER
2. Open the upper and lower covers. (Fig. 4.16)
3. Adjust the top and bottom guides so that are
not touching the blade.
4. Make sure that the blade has been tensioned as
per the instructions on Page 15.
wheel may have sharp burrs and the blade teeth may
extend beyond the edge of the wheel, creating a lac-
eration hazard. Be careful when turning the wheels by
hand.
5. Turn the upper wheel by hand around two to three
times to see how the blade is tracking.
6. Loosen the lock lever (Fig. 4.17) so that the blade
tracking knob can rotate.
7. Manually rotate the upper wheel, taking care not to
touch the blade. At the same time turn the
adjusting knob (Fig. 4.17) clockwise or anticlock
wise until the saw blade tracks centred on the
rubber tyre.
8. After adjustment, re-tighten the tracking lock
lever and close the cover.
Fine Trackig Adjustment
During setup, the blade was tracked without the
machine connected to power. In this procedure, the
bandsaw is turned ON to perform fine blade tracking.
Make small changes with the blade tracking knob as
you monitor the effect on the blade tracking.
Close the wheel covers and turn the bandsaw ON.
Observe the blade tracking path through the clear
window on the right edge of the bandsaw, (Fig. 4.18)
Using the tracking controls, adjust the blade so that it
tracks on the center of the wheel. Tighten the tracking
lock to secure the setting.
