Jet Tools PB-85, PB-150 Miter Cuts, Bow Depth Stop, Blade Tension, Blade Tracking

Miter Cuts

The band saw’s bow can be swiveled for miter cuts (up to 45° on the Model PB-85; up to 60° on the Model PB-150). Loosen the handle (A, Figure 9) and pivot the bow to the desired angle on the scale (B, Figure 9).

Adjustable stops (C, Figure 9) for square and 45° enable a quick setup.

NOTE: The handle (A, Figure 9) can be adjusted so that it does not interfere with other parts of the machine. Simply pull up on the handle, rotate it on the pin, then release the handle making sure it seats itself properly on the pin.

Bow Depth Stop

The stop (D, Figure 9) controls the depth to which the bow falls and prevents the blade from contacting the base. This stop has been set at the factory. If future adjustment is ever needed, loosen the hex nut and turn the screw with a hex wrench. When the depth stop is properly set, retighten the hex nut.

Blade Tension

Rotate the knob (Figure 10) clockwise to tighten the blade on the wheels. Do not overtighten.

The model PB-150 has a tension indicator, shown in Figure 11. The tension is correct when the indicators are aligned.

Blade Tracking

Tracking the blade requires that the band saw be operating while the back cover is removed. Use extreme caution.

Blade tracking has been set at the factory and should require no adjustment. Since tracking can only be accomplished with the blade moving and the back cover removed, it is suggested that any blade tracking be accomplished by qualified personnel who are familiar with this type of adjustment and the dangers associated with it.

Tracking is set properly when the back of the blade, while running, lightly touches the lip of the wheel. NOTE: Over-tracking (allowing blade back to rub hard against wheel lip) will damage the blade wheels and blade.
