Adjusting Blade Tension

1. Disconnect machine from the power source,

unplug.

2. Turn blade tension hand wheel (E, Fig. 2)

counter-clockwise to tension blade, and
clockwise to loosen the tension. A gauge on
the upper wheel slide bracket (F, Fig. 2)
indicates the approximate tension according to
the width of the blade. The JWBS-16B comes
with a 3/4” blade so the tension should be set
at 3/4” when using this blade.

As you become familiar with the saw, you may find
it necessary to change the blade tension from the
initial setting. Changes in blade width, and the type
of material being cut will have an effect on blade
tension.

Keep in mind that too little, or too much blade
tension can cause blade breakage and/or poor
cutting performance.

Adjusting Blade Tracking

Disconnect machine from the

power source! Never adjust blade tracking with
the machine running! Failure to comply may
cause serious injury!

Note: Blade tracking has been adjusted at the
factory. If, however, it is determined that blade
tracking needs adjustment:

1. Blade must be properly tensioned before

adjusting blade tracking. Make sure upper and,
lower blade guides do not interfere with the
blade while adjusting the tracking.

2. Open the upper wheel door. Rotate the wheel

forward, and observe the position of the blade
on the wheel. The blade should rest in
approximately the center of the wheel.

3. If adjustment is necessary, loosen the wing nut

(G, Fig. 2) at the top rear of the saw.

4. Adjust tracking by turning the knob (H, Fig. 2)

in 1/4 turn increments. Rotate the wheel
forward, and observe the position of the blade
on the wheel. Rotating knob (H, Fig. 2)
counter-clockwise should move the blade
towards the front of the wheel. Rotating the
knob clockwise should move the blade towards
the back of the wheel.

5. Continue with adjustments until the blade is

tracking properly.

6. Tighten the wing nut (G, Fig. 2).

Upper Blade Guide Adjustment

Disconnect machine from the

power source, unplug before making any
adjustments! Blade teeth are sharp! Use care
when working near the saw blade. Failure to
comply may cause
serious injury!

1. Blade tension and tracking must be properly

adjusted prior to blade guide setup.

2. The blade guard has been removed in Figure 3

for photo purposes only.

3. Loosen the socket head cap screw (A, Fig. 3)

and position the blade guide assembly
(B, Fig. 3) so that the guides rest just behind
the gullet of the blade teeth. Tighten the socket
head cap screw.

4. Loosen lock nuts (D, Fig. 3).

5. Adjust guide knobs (E, Fig. 3) so guides

(C, Fig. 3) rest lightly against the blade. Do not
force the guides against the side of the blade.
Tighten both lock nuts.

6. Adjust the blade support bearing so that it is

0.003” away from the back of the blade, about
the thickness of a piece of paper. To make this
adjustment loosen wing nut (F, Fig. 3) and slide
the bearing and bearing post into position.
Tighten wing nut.

Note: Blade support bearing should be adjusted so
that the back edge of the blade overlaps the front
face of the ball bearing by approximately 1/8”. If
adjustment is needed loosen wing nut (F, Fig. 3)
and turn the bearing shaft. Tighten wing nut.
