5. Using a machinist’s square, check to make
sure the table is 90 degrees to the blade.
USING LEATHER PROTECTIVE GLOVES,
turn the upper drive wheel to check the
squareness at a minimum of three points on
the blade
6. If the table is not level, unlock the lock nut on
the table leveling bolt.
7. Turn the leveling bolt as required to make the
table square to the blade.
8. Lock the leveling bolt lock nut and recheck the
table level. When the table is level.
9. Lock the table lock knobs securely and
recheck for level. Adjust as necessary until
the table is level while everything is tightened
to working tightness.
10. With everything is locked down, look at the
pointer for the angle gauge. It should be
exactly on the zero mark of the gauge (Figure
13). If not, loosen the pointer screw, adjust the
pointer until it is on zero, then tighten the
pointer screw while holding the pointer
securely in position on zero.
Adjusting Miter Gauge Slot
Parallelism
The miter slot should be parallel to the side of the
blade. If the saw is not cutting straight when using
the miter gauge, the miter slot may not be parallel.
1. Put a straight edge against the blade. Make
sure to position the blade so tooth offset does
not affect the straight edge.
2. Measure from both ends of the miter slot to the
straight edge.
3. If the measurements are not equal at both
ends of the slot, loosen six bolts securing the
table to the table trunnions (see Figures 13
and 14.)
4. Adjust the table until it is parallel with the
blade.
5. Tighten the trunnion attaching bolts.
Adjusting Blade Speed (Models J-
8201/J-8203)
Figure 7 provides blade speeds for various
materials. To adjust the blade speed, change the
clutch position of the clutch (in or out) and the
position of the drive belt on the pulleys on the
motor and reduction gearbox shafts.
Adjusting Blade Speed (Models J-
8201VS/J-8203VS)
See Figure 10.
1. The blade speed is controlled by an
adjustment mechanism on the right end of the
saw. Speed increases or decreases as the
knob is turned.
2. A placard on the drive belt guard (shown
below) provides recommended speeds for
various materials.
3. A speed indicator is provided on the barrel of
the adjustment mechanism. In surface feet per
minute; Position 0 = 334, 1 = 262, 2 = 216, 3
=171, 4 = 137, and 5 = 116.
4. Turn the speed adjustment knob to the desired
setting as determined by the material being
cut.

Changing Clutch Position
WARNING: NEVER attempt to shift the clutch
mechanism while the saw is running. The saw
must be turned off before clutch is shifted.
1. Turn the main switch to off.
2. Pull the door open on the pulley case.
3. Turn the clutch handle clockwise and push in,
to engage the high speed pulley drive. Or, turn
the clutch handle clockwise, and pull out, to
engage the reduction gearbox drive.
NOTE: When pushing or pulling the clutch
knob, the dogs on the clutch mechanism are
being engaged. Take the time to make sure
the clutch handle is all the way in, or all the
