STEP FIVE:
ADJUSTING BLADE AND BOTTOM BEARINGS
Adjusting Blade Tension and Tracking
1. The blade adjustment screw (part #33A) is used to control the tension of the
band saw blade. Turning the screw clockwise increases the tension. The blade
tension should be released when the saw is out of use for any length of time.
2. The tracking knob (#34) to the side of the blade adjustment screw controls the
blade’s tracking. Turning the knob left or right will alter the lateral movement of
the top drive pulley. The tracking knob has a lock nut and must be loosened to
change the tracking; be sure to retighten it before turning the saw back on. The
blade should be positioned in the centre of the wheel.
TIPS ON ADJUSTING BLADE TENSION AND TRACKING:
• Track the blade each time you put a new or different blade on the band saw. Make
sure the machine is unplugged before making any adjustments.
• Ideal blade tension may vary with the type of blade you use and the type or thickness
of stock you are cutting. See TROUBLESHOOTING on page 23.
Adjusting Bottom Bearings
3. Do the bottom bearings adjustments before mounting the table bracket and
working table.
4. Using the Allen key (supplied), position the bottom bearings behind the kerf of
the blade. Adjust the thrust bearing so the blade doesn’t move when the bearing
moves. Tighten with the Allen key. Adjust the side bearings to the same distance
from the blade (close but the blade should still run free).
TIP ON ADJUSTING BEARINGS:
• Fold a piece of paper in half (use paper currency if it’s handy). Put it between the
bearing and the blade. Adjust the bearing close enough to the blade so that the paper
can move freely, the bearing runs free, but the blade doesn’t move.
