OPERATION MANUAL

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.

The cast iron spokes of the upper

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.
