Setting Blade Speed; Blade Guide Adjustment - Jet HVBS-710S Operating Instructions And Parts Manual

Figure 22
The saw blade can be considered correctly
adjusted when the variation measure is no more
than 0.012 inch across the face of the disk.
If you do not have a piece of 2-inch bar stock
available for a test cut, use a larger diameter
test piece rather than a smaller one. The
maximum thickness variation on any test piece
should be no more than 0.003 inch, per side, per
inch of stock diameter.

9.11 Setting blade speed

1. Turn machine OFF.
2. Loosen knob (A, Figure 23) and open pulley
cover.
3. Reduce belt tension by turning the two
screws (B, Figure 23) counterclockwise.
4. Slip belt over pulleys for desired speed,
according to chart inside pulley cover (also
shown in Figure 24).
5. Tighten screws to tension belt. Proper
tension is when center of belt can be pushed
with a finger approximately 1/2-inch.
Material chips or shavings are the best indicator
of proper blade speed and downfeed rate. See
section 11.4, Evaluating cutting efficiency.
The belt should be parallel from motor pulley to
worm pulley. If adjustment is needed, loosen the
nuts holding the motor to the plate, and adjust
motor until belt is parallel. Retighten nuts.

9.12 Blade guide adjustment

1. Loosen knobs (A, Figure 25).
2. Slide guide
workpiece as possible, without interfering
with the cut. This will prevent excessive
blade exposure, and deflection of blade
during cutting.
3. Retighten knobs.
The guide bearings come pre-adjusted from the
factory, but should be inspected frequently and
adjustments made as needed.
For most efficient operation and maximum
accuracy, provide 0.001" clearance between the
blade and the guide bearings. The bearings will
still turn freely with this clearance. If the
clearance is incorrect, the blade may track off
the drive wheel.
