Adjustments Adjusting Blade Support/Guide Height The upper blade support and guide mechanism can be adjusted to accommodate the height of the work piece. 1. To adjust the support, loosen the knob that clamps the support rod, then move the support up or down in its holder. (Refer to Figure 3 for location of the support mechanism.) 2. Adjust the support so that there is space between the support and work piece. Space of approximately 1/8-inch is generally appropriate. Adjusting Blade Tension Blade tension is set by a spring loaded tension mechanism on the upper drive wheel. Check the level of the tension device before cutting. The tension for various blade widths is indicated on the casting on the tension device. Adjusting Table Angle (Refer to Figure 9.) The angle gauge is under the front of the table. The angle gauge shows the angle of the table relative to the saw blade. The table is mounted on trunnions that allow adjustment downward 45 degrees, and upward 10 degrees. Loosen the two trunnion lock knobs slightly to adjust the table angle and retighten the lock knobs. Figure 8: Saw Blade Tension and Tracking Mechanism Figure 9: Table Tilt Mechanism and Angle Gauge NOTE: By adjusting the positive leveling stop on the table leveling mechanism, it is possible to tilt the table upward 10 degrees. When returning to0 degrees, the table leveling mechanism must be reset after completing the sawing operation (refer to Machine Set-up). WARNING: When cutting at an angle with a tilted table, provide a guide against which the material being cut can rest. Cutting "freehand" at an angle can result in injury, and make it difficult to maintain an accurate cut. Leveling Work Table The table can be adjusted to level the table relative to the saw blade. Use the following method: 1. Unplug the electrical cord or open the circuit breaker in the branch circuit. 2. Move the upper blade guide assembly to the very top of its travel. 3. Make sure the blade is straight, and fully tensioned. (A damaged or worn blade may provide a poor reference surface for squaring the table.) 14

Adjustments
Adjusting Blade Support/Guide
Height
The upper blade support and guide mechanism
can be adjusted to accommodate the height of the
work piece.
1.
To adjust the support, loosen the knob that
clamps the support rod, then move the support
up or down in its holder.
(Refer to Figure 3 for
location of the support mechanism.)
2.
Adjust the support so that there is space
between the support and work piece. Space of
approximately
1/8-inch
is
generally
appropriate.
Adjusting Blade Tension
Blade tension is set by a spring loaded tension
mechanism on the upper drive wheel.
Check the
level of the tension device before cutting. The
tension for various blade widths is indicated on the
casting on the tension device.

Mechanism
Adjusting Table Angle
(Refer to Figure 9.) The angle gauge is under the
front of the table. The angle gauge shows the
angle of the table relative to the saw blade. The
table
is
mounted
on
trunnions
that
allow
adjustment downward 45 degrees, and upward 10
degrees. Loosen the two trunnion lock knobs
slightly to adjust the table angle and retighten the
lock knobs.
Figure 9: Table Tilt Mechanism and Angle
Gauge
NOTE:
By adjusting the positive leveling stop on
the table leveling mechanism, it is possible to tilt
the table upward 10 degrees. When returning to0
degrees, the table leveling mechanism must be
reset after completing the sawing operation (refer
to Machine Set-up).
WARNING:
When cutting at an angle with a
tilted table, provide a guide against which the
material being cut can rest. Cutting “freehand”
at an angle can result in injury, and make it
difficult to maintain an accurate cut.
Leveling Work Table
The table can be adjusted to level the table relative
to the saw blade.
Use the following method:
1.
Unplug the electrical cord or open the circuit
breaker in the branch circuit.
2.
Move the upper blade guide assembly to the
very top of its travel.
3.
Make sure the blade is straight, and fully
tensioned. (A damaged or worn blade may
provide a poor reference surface for squaring
the table.)
