ADJUSTMENTS

ADJUSTING THE BLADE GUIDES AND BEARINGS

See Figure 18.

Disconnect the machine from the power source before making any

adjustments!

Adjust the upper blade guides and blade support bearings only after the blade has the correct tension and is tracking properly.

The DELTA® 14" Steel Frame Band Saw features two upper and lower side bearings and two upper and lower rear bearings that can be adjusted in order to ensure straight and consistent cuts. It is recommended that you periodically check the position of all bearings and adjust if necessary.

Side Bearings

The upper and lower side bearings (A) should be positioned so that there is approximately 1/64" gap on either side of the blade. To adjust the position of the bearings, side-to-side, do the following:

Use a 3MM Allen wrench to loosen the bearing screws (B).

Reposition the bearings and tighten the bearing the screws.

The upper and lower side bearings also adjust back and forth and should be positioned so that the front edge of the bearings is just behind the blade gullet. To adjust the position of the bearings, front-to-back, do the following:

Use a 13MM open wrench to loosen the top retaining nut and a 10MM open wrench to loosen the bottom retaining nut. (The bottom retaining nut can be made more accessible by tilting the table slightly.)

With the retaining nut loosened, both upper side bearings or both lower side bearings will move back and forth as a unitPosition them so that the front edge of the bearings are just behind the blade gullet.

Re-tighten the retaining nuts.

Rear Bearings

NOTE: The upper and lower side bearings must both be set in place prior to adjusting the upper and lower rear bearings.

The upper and lower rear bearings should be positioned so that they nearly touch the blade.

• To adjust, use a 3MM Allen wrench to loosen the bearing screws.

• Reposition the bearings and tighten the bearing the screws.
