Autoclutch InstallationWiring Instructions 1

1.4 Wiring Instructions

DANGER! The key switch should still be off, the keyremoved and the negative battery cable disconnected asstated at the beginning of this section. The incoming powersupply of electric-powered sawmills should be discon-nected and locked out. Failure to do so will result in seriousinjury or death.

IMPORTANT! Avoid pinch and pivot points, unnecessarywire bending and open spaces where the wire could getcaught by a log, etc. If you have any questions, callWood-Mizer customer service.

Refer to the appropriate wiring diagram while perform-ing the wiring steps below (See Section 5.3).

1. 1998 and newer model sawmills are pre-wired for the autoclutch option. Locate the har-ness of four wires (#28, 29, 31, & 32) extending from the top of the conduit connecting thecontrol box to the saw head.

2. Remove any wire ties, tape or cable clamps securing the harness in its storage location. Ifnecessary, install the provided expandable conduit around the four wires and route theassembly through the cable clamp you installed behind the autoclutch assembly. Con-tinue the cable to the autoclutch. NOTE: The laser option wire #25 may be bundled withthe autoclutch option wires. If so, separate wire #25 and return it to the storage location.

3. Pull back the harness conduit to expose the four wires. Connect the 12 gauge black wire(#32) to the black autoclutch motor wire. Slide the supplied piece of rubber tube over oneof the wires and overlap the terminals on both wires. Fasten the wire terminals togetherwith the #10-24 x 3/8" screw and lock nut provided. Slide the rubber tube over the termi-nal connection and wrap with electrical tape.

4. Connect the 12 gauge red wire (#31) to the bottom terminal of the autoclutch solenoid.Remove the nut from the solenoid terminal and slide the wire ring terminal onto the stud.Replace the solenoid terminal nut.

5. Connect one of the 14 gauge red wires (#28) to the red wire from the autoclutch engageswitch. These wires have quick connects which simply snap together. Connect the other14 gauge red wire (#29) to the red wire from the autoclutch disengage switch in the samemanner.


Autoclutch InstallationWiring Instructions1

6. In the control box, locate the harness of four wires (#28, 29, 31, & 32). Remove any wireties, tape, or cable clamps securing the harness in its storage location. Pull back the har-ness conduit to expose the four wires. NOTE: Black wire #32 should be pre-installed tothe ground terminal stud in the bottom of the control box.

7. Connect the 14 gauge red wire (#28) to the bottom terminal of the autoclutch toggleswitch. Slide the wire terminal onto the switch terminal tab. Connect the other 14 gaugered wire (#29) to the top terminal of the autoclutch toggle switch in the same manner.

8. Connect the pre-installed red wire from the middle terminal of the autoclutch toggle switchto the Accessory circuit breaker. The Accessory circuit breaker is the second from the leftas you face the front of the control box. Remove the nut from the front circuit breaker ter-minal stud (closest to the front of the control box). Slide the wire ring terminal onto the cir-cuit breaker terminal stud and replace the nut. Be sure to maintain all other wireconnections on the circuit breaker terminal.

9. Connect the 12 gauge red wire (#31) to the bottom terminal of the 30 amp circuit breakeryou installed to the back wall of the control box. Slide the wire connector onto the circuitbreaker tab.

MaintenanceTroubleshooting3

3.6 Troubleshooting

Problem Cause Solution

Autoclutch will not stop; continues to engage and disengage

Cam and switches not aligned properly

Check microswitch alignment (See Sec-tion 3.5)

Microswitch damaged due to mis-alignment

Position autoclutch switch, in center position. If autoclutch stops, inspect microswitch lever. If bent, replace switch.

Autoclutch will not engage or disengage

15Amp or 30Amp breaker tripped; 15Amp ACC Breaker (CB4) tripped

Check and reset as needed

Cam and switches not aligned properly

Check microswitch alignment (See Sec-tion 3.5)

Bad microswitch Use volt meter to measure voltage at small post of solenoid (Solenoid 6) to chassis ground. If no voltage is present, replace microswitch and repeat align-ment procedure. (If you don’t have a volt meter, try to notice if solenoid is clicking. If it is not clicking, replace microswitch.)

Bad chassis ground at sole-noid

If there is +12V at small post on solenoid but it does not click, tighten solenoid mounting bolts for a better ground

Bad Autoclutch motor, motor brushes or armature

Disconnect both motor leads from circuit. Use an ohm meter to check continuity between the motor leads. If no continuity, inspect brushes, brush springs and armature. Rebuild or replace motor as necessary.

Motor overheating Drive belts are too tight. Check belt ten-sion and adjust properly.

Gearbox binding Check gearbox oil. Refill or replace as necessary.

Bad solenoid If solenoid clicks, +12V is measured at small post and ground to solenoid is good, but +12V is measured at only one large post, replace solenoid.

Autoclutch will engage or disengage only (won’t do both)

Bad microswitch connection Ensure good connection. If Autoclutch won’t disengage, the disengage switch (wire #29) must be reconnected. If Auto-clutch won’t engage, the engage switch (wire #28) must be reconnected.
