Belt Replacement; Dro Calibration And Operation - Powermatic PM2000B Série Manuel D'instructions D'utilisation

4. Push motor to the right and tighten screw (C)
to tension belt. Retighten nut (D). Verify proper
tension by pushing on belt midway between
pulleys; deflection should be about 1/2-inch.
If belt shows signs of wear, fraying, cracks, etc. it
should be replaced, as follows.

8.9.2 Belt replacement

See Figure 8-12.
1. Lower trunnion completely.
2. Loosen screw (C) with 17mm wrench.
3. Slightly loosen nut
adjustable) wrench.
4. Pivot motor to the left to release tension.
5. Replace belt.
6. Push motor to the right and tighten screw (C)
to tension new belt. Retighten nut (D). Verify
proper tension by pushing on belt midway
between pulleys; deflection should be about
1/2-inch.

8.10 DRO calibration and operation

When the 0° and 45° blade tilt stops have been
verified to be correct, the DRO (digital readout) can
be calibrated to match the settings.
Sect. 8.10.1 describes
procedure. Sect. 8.10.2 describes mandatory
calibration procedures if the PCB sensor is ever
replaced in the table saw.
8.10.1 General calibration
1. Blade tilt stops must be correctly set. See sect.
8.6.
2. Connect machine to power source. DRO will
be illuminated.
3. If saw blade is relatively close to 0°, set blade
to exactly 0° and press "SET 0" button.
Readout will display 0.00. See Figure 8-13.
Or, if saw blade is relatively close to 45°, set
blade to 45°, and press "SET 45" button.
Readout will display 45.0.
(D) with 1-1/4" (or
general calibration
4. Calibration is complete.
NOTE: If power is disconnected, digital display will
reset to 0.00. When power is restored, repeat
above procedure.
8.10.2 PCB replacement calibration
1. Blade tilt stops must be correctly set. See sect.
8.6.
2. Connect machine to power source. DRO will
be illuminated.
3. Tilt saw blade to 0°.
4. Press and hold both SET buttons until display
shows "---" (Figure 8-14).
5. Release buttons and display will show "00.0".
6. Calibration at 0° is complete. (If "00.0" does
not display, disconnect from power, reconnect
and repeat above procedure.)
7. Tilt blade to 45°.
8. Press and hold both SET buttons until display
shows "---" (Figure 8-14).
9. Release buttons and display will show "45.0".
10. Calibration at 45° is complete. (If "45.0" does
not display, disconnect from power, reconnect
and repeat above procedure.)
